　　When electricity consumption is low, it is "charged" and stored through the power grid, and the stored electric energy is released until the peak of electricity consumption to ensure the stability of the power system — — This kind of energy storage power station, whose principle is similar to "charging treasure", has been widely used in China in recent years, which has played an important role in stabilizing power supply.

　　A few days ago, the National Development and Reform Commission and the National Energy Administration issued the Notice on Further Promoting the New Energy Storage to Participate in the Electricity Market and Dispatch (hereinafter referred to as the Notice), clarifying that the new energy storage can participate in the electricity market as an independent energy storage, and making arrangements for its market mechanism, price mechanism and operation mechanism. According to industry analysts, this move will strongly promote the development of new energy storage industry, and then provide strong support for China to build a new power system.

　　What is new energy storage?

　　— — Besides pumped storage, new energy storage technologies include new lithium ion batteries, flow batteries, compressed air, etc.

　　Have you ever seen a power station that doesn’t burn coal or natural gas, but lets the air "show its talents"?

　　On May 26th, Jiangsu Jintan Salt Cave Compressed Air Energy Storage Project was officially put into operation. Cao Qingwei, the chairman of Jiangsu Company of China Huaneng Group, who is responsible for the construction and operation of the project, told this reporter that as the world’s first non-afterburning compressed air energy storage power station, the power station does not burn coal or natural gas, but drives the turbine generator set to rotate and generate electricity through compressed air. When the electricity consumption is low, the air is compressed into the salt cave by electric energy, and the air is released at the peak of electricity consumption to generate electricity. After the project is put into production, it can provide 60,000 kilowatts of peak-shaving capacity for local power grids, and can store 300,000 kWh of electricity in one energy storage cycle, and increase the peak-shaving power by about 100 million kWh every year, thus realizing "peak-shaving and valley-filling" of power supply and demand.

　　Compressed air energy storage is a new energy storage technology, and its function can be commonly understood as "charging treasure". As the power is ready to use, it is often necessary to increase the power investment according to the peak load demand, which is not only costly, but also prone to surplus power supply. Using energy storage technology to store power at the low power consumption and release it at the peak power consumption can effectively avoid the "uneven busy and idle" of power system and ensure the stability of power supply.

　　"New energy storage is relative to traditional energy storage." Ceng Ming, director of the Energy Internet Research Center of North China Electric Power University, told this reporter that the main representative of traditional energy storage is pumped storage power stations, while new energy storage refers to new energy storage technologies other than pumped storage, including new lithium-ion batteries, flow batteries, compressed air and mechanical energy storage.

　　"In recent years, the traditional energy storage represented by pumped storage power stations has developed rapidly, and the technology is relatively mature and widely used." Ceng Ming said that promoting the development of new energy storage on this basis is closely related to its characteristics of quick response, wide functions, flexible configuration and short construction period. From the site selection and layout, the new energy storage has more space to be laid out and stronger environmental adaptability. It can be deployed on the power generation side, power grid side and user side, and can be laid out in a large scale or distributed manner. From the function point of view, the new energy storage can play the role of peak regulation and frequency modulation, and can also be used as a backup power supply to smooth the fluctuation of wind power generation and photovoltaic power generation.

　　In recent years, China has accelerated the development and utilization of renewable energy, and the concept of green and low carbon has been deeply rooted in people’s hearts. However, wind power and photovoltaic have the characteristics of "looking at the sky and eating". When it is "extremely hot without wind" and "extremely cold without light", it will easily lead to fluctuations in power supply. "To maintain the stability of frequency and voltage, it is necessary to systematically schedule energy storage resources to smooth the fluctuation of new energy power generation." Ceng Ming said that this includes unified dispatching of power system and optimized dispatching of distributed new energy storage within its own scope. In recent years, new formats such as virtual power plants can also ensure power stability by dispatching energy storage resources.

　　Clarify the identity of market subject

　　— — New energy storage can participate in the power market as an independent energy storage; If an independent energy storage power station sends electricity to the power grid, the corresponding charging amount will not bear the transmission and distribution price, government funds and surcharges.

　　With the accelerated development of renewable energy, the construction of new energy storage projects in China has obviously accelerated. By the end of 2021, the cumulative installed capacity of new energy storage in China has exceeded 4 million kilowatts, and application scenarios such as "new energy+energy storage", conventional thermal power configuration energy storage, and smart microgrid are constantly emerging, and the business model is gradually expanding, which initially shows its supporting role for energy transformation.

　　However, due to the lack of clarity in the identity positioning and investment return mechanism of new energy storage in the power market, the enthusiasm of market participants for investment and construction has been affected to some extent. "In the past, the relevant market rules mainly clarified that energy storage participated in the auxiliary service market of peak shaving and frequency modulation. However, the design of rules for energy storage participating in medium and long-term transactions, spot transactions and other markets, especially the access standards and registration, trading and settlement rules, still needs to be refined and improved." Huang Bibin, deputy director of the Institute of New Energy and Statistics of State Grid Energy Research Institute, told this reporter.

　　From the power generation side, at present, most of the new energy storage in China is combined with new energy or thermal power generating units, and the adjustment function of energy storage is used to improve the frequency modulation performance of thermal power, and the compensation for frequency modulation auxiliary services is obtained, and the related benefits are not high. In terms of independent energy storage, if the charging and discharging price mechanism is not clear, if it is implemented with reference to the traditional price mechanism of power users and generator sets, the power station, as a power user, needs to pay the on-grid price, transmission and distribution price, government funds and additional and related taxes and fees; However, when discharging to the power grid, independent energy storage is equivalent to a generator set, and only benefits such as electricity price and auxiliary services are obtained. When the power grid sells the electricity released by independent energy storage to the end users, the buyers still have to pay the transmission and distribution price, government funds and surcharges.

　　In order to better promote the development of new energy storage industry, the Notice issued this time proposes that new energy storage can participate in the power market as an independent energy storage. At the same time, accelerate the promotion of independent energy storage to participate in the power market and cooperate with the peak shaving of the power grid. If an independent energy storage power station sends electricity to the power grid, the corresponding charging amount will not bear the transmission and distribution price, government funds and surcharges.

　　"Encourage the signing of market contracts during peak hours and low hours, and refine the profit mode of independent energy storage participating in the power market; It is clear that the charging amount does not bear the transmission and distribution price, government funds and surcharges, etc., which solves the problem that the original charging amount price mechanism is unclear, and is conducive to promoting the development of independent energy storage and making profits in a market way. " Huang Bibin said.

　　Taking Shandong Province with independent energy storage power station as an example, according to the purchasing electricity price released by Shandong Electric Power Company of State Grid in March this year, the electricity transmission and distribution price for power users of 220kV and above is 0.1169 yuan/kWh, and the government funds and surcharges are about 0.027 yuan/kWh. According to industry insiders, after the implementation of the new policy, the independent energy storage participating in the spot market in Shandong will benefit directly, and the income from power consumption is expected to increase from 0.1 yuan to 0.2 yuan/kWh.

　　Promote the development of large-scale "charging treasure"

　　— — New energy storage on power generation side, user side and power grid side can participate in market transactions; Accelerate technical support and promote new energy storage to achieve high-quality development

　　On May 27th, the civil engineering of flywheel energy storage project of Ningxia Electric Power Lingwu Company, the national energy group, was completed, becoming the first full-capacity flywheel energy storage project in China — The project of combined frequency modulation of thermal power is also the project with the largest power of flywheel energy storage unit and the largest total energy storage in the world. "The biggest feature of this project is full magnetic levitation, low energy consumption and fast response. The life cycle can be designed as 25 years, and more than 10 million times of storage and discharge can be realized during this life cycle. The conversion between charging and discharge can reach millisecond level, which can effectively meet the needs of rapid frequency modulation of power grid." Diao Shijun, deputy general manager of Ningxia Electric Power Lingwu Company of National Energy Group, told the reporter.

　　At present, the new type of energy storage with configuration is mainly used to adjust the instability of power generation. The Notice proposes that new energy storage projects in the form of distribution and construction should be encouraged to be combined with other types of power supplies and regarded as a whole, and participate in the power market in accordance with existing relevant rules. At the same time, encourage new energy stations and energy storage facilities to jointly participate in the market, use energy storage to improve the network-related performance of new energy, and ensure the efficient consumption and utilization of new energy.

　　"Encouraging the joint participation of new energy distribution and its affiliated power sources in the power market will help the new energy storage to better carry out medium and long-term time-sharing curve trading, improve the performance of new energy in the spot market, and provide more support for power system regulation, which will further promote the development of new energy storage technologies on the new energy side." Huang Bibin said.

　　In addition to the power generation side, the Notice also puts forward requirements for the market-oriented construction of new energy storage on the user side and the power grid side, clearly further supporting the development of energy storage on the user side, "moderately increasing the peak-valley price difference to create space for the development of energy storage on the user side" and "encouraging further increasing the upper and lower prices of the medium and long-term power market and the spot market, guiding the user side to actively allocate new energy storage, and increasing the revenue channels for energy storage on the user side". At the same time, it is required to establish a price mechanism for energy storage on the grid side.

　　Huang Bibin told reporters that taking lithium-ion battery energy storage, which has developed rapidly in recent years, as an example, the current system construction cost is about 1,500 yuan ~ 2,000 yuan/kWh, but the life-cycle electricity cost is still 2-mdash of pumped storage; Three times. "The promulgation of the Notice will create conditions for new energy storage such as lithium-ion battery energy storage to participate in various power markets and obtain reasonable income."

　　The growth of the new energy storage industry is also inseparable from technological innovation. Huang Bibin believes that the new energy storage technology in China has made great progress at present, but the core indexes such as efficiency, capacity and service life still need to be broken, especially when the output time of new energy is limited under extreme weather conditions, there is a lack of new energy storage technology with large capacity and long period for system regulation. He suggested that in the future, with the goal of ensuring power supply and the safe and stable operation of the power grid, we should focus on promoting the research and development and system integration of new energy storage core technologies and equipment with large capacity, long period, low cost and high safety by deepening collaborative innovation of Industry-University-Research users and developing demonstration applications, so as to help the new energy storage industry achieve high-quality development.

1905 movie network news On March 26th, the film produced by Xú Zhēng and starring in it held a "The Birth of Drama Essence" conference in Beijing. Producer Xú Zhēng, director Pengyuan Ren and starring Claudia, Yanhui Wang and Duan Bowen appeared. After a lapse of three years, Xú Zhēng returned to the big screen. Although it was not the most familiar comedy for the audience, he revealed that the play had made him addicted to it. On the same day, Xú Zhēng also exchanged roles with Yanhui Wang and performed their opposite plays in the movie.

　

The movie "Behind the scenes player" tells the story of Zhong Xiaonian (Xú Zhēng), who has hundreds of millions of assets, who suddenly encounters an accident when his career is in full swing, and realizes his self-salvation after a series of embarrassing situations. When talking about the reasons for taking this film, Xú Zhēng bluntly said that the film satisfied his addiction to drama. "After getting the script, I finished reading it in one breath. Apart from the characters and stories, there are also many challenges in performance, especially the one-man show in a closed space, which makes me want to play."

　

Speaking of the role of Zhong Xiaonian, director Pengyuan Ren also recalled the casting process. He said that he was an actor who demanded "good acting" and "conforming to the role". Later, the producer told him that the script had been handed to Xú Zhēng. "At that time, I had two words in my mind, hehe, and I thought it was impossible." Xú Zhēng asked, "What do you mean by’ hehe’?"

　

In the film, Xú Zhēng and Claudia play the role of husband and wife. In a stills released by the film, the crew "changed their heads" to the stills taken before Claudia and Wu Yifan. Xú Zhēng also laughed and said, "I think it is quite appropriate."

＂Crowd＂ exposes director’s special to guide Andy Lau’s ＂soul pumping＂


1905 movie network news On February 10, the Spring Festival inspirational comedy starring director Rao Xiaozhi was revealed to the audience for his unique absurd comedy style.

But who knew that Rao Xiaozhi, who had won 790 million box office and high reputation as a dark horse, was in a long period of anxiety after entering the "Crowd" project, and even "nervous enough to suspect that he had a heart attack".


In the face of the strongest Spring Festival, in the face of Andy Lau’s joining, Rao Xiaozhi admitted that the popularity of "Crowd" had a bad start and was worried that it would live up to Brother Hua’s expectations, but Andy Lau’s reply gave him a shot in the arm: "Your talent will definitely be seen."


Xiao Yang was tortured the worst by Rao Xiaozhi, but still praised him as a "natural director"

The studio director Andy Lau’s "soul pumping" skillfully explains the troubles of Wan Qian’s lines


As a friend of Rao Xiaozhi for many years, Xiao Yang did not hide her recognition of the director. On the set of "The Crowd", Xiao Yang was always the one who was abused the most. The director’s requirements for him were also very high, always saying "another one" "can be better", and even in a scene where Liu Dehua slapped Xiao Yang bluntly: "Brother Hua should really fan it, the effect of real fan is better."


So Xiao Yang was forcibly slapped by Liu Dehua 36 times. But when it comes to the evaluation of the director, Xiao Yang still sincerely said that "he is naturally suitable to be a director, because he is not only immersed in his own world, but also can solve the difficulties in reality tit for tat." For example, when Wan Qian was faced with a difficult line and asked for advice on the spot, Rao Xiaozhi could immediately "prescribe the right medicine" to help her understand the character’s mood.


As a director with a very strong personal style, Rao Xiaozhi has an innate sense of humor, just as Xiao Yang described it as a "high-level joy." In the filming of the scene where Andy Lau taught Xiao Yang how to play the role of being stabbed to death, the director took a flash of inspiration from Andy Lau’s traditional character characteristics and proposed, "Brother Hua, you can add that kind of twitch." As it turned out, the performance became one of the most talked-about passages because of the temporary "twitch".


Andy Lau’s original sound in Mandarin, Rao Xiaozhi incarnated as a "sparring partner"

The line "nanny style" demonstration is very professional


At the request of the director, the whole film of "Crowd" must be played by Andy Lau in Mandarin, and no dubbing is used. It is difficult to know that there are not many movies with the original sound of Hua Ge’s Mandarin, and what is even more difficult is that he has to read the tongue twister "800 Pacesetters Run to the North Slope" fluently in the film. It is said that this tongue twister scene is also the most difficult one for Hua Ge. He practices back and forth on the set and reads the script anytime and anywhere.


In this director’s special, Andy Lau broke the news that "the director will read every line specially to me." In order to have a better line effect, the director will read every line to Andy Lau first, and then the two will communicate the final expression effect. Especially for some lines of stage performances, the stage director Rao Xiaozhi will read words synchronously with Brother Hua, looking for differences, and perfecting them to the best effect over and over again.


Deng Chao’s retro style appeared on Weibo night, and the gentleman’s funny style was seamlessly switched

Deng Chao interacts with the audience


1905 movie network news Deng Chao’s retro look appeared on the 2017 Weibo night. The classic black dress was paired with a white shirt, and the overall shape was casual and handsome. On the red carpet, Deng Chao showed a warm side, not only taking care of his red carpet companion Angelababy, but also interacting happily with photographers in different positions. When taking POSE photos, Deng Chao also showed his true colors as a ghost horse. After making a few handsome and serious movements, his style changed into a funny style, sometimes raising his hand and making a "take off" gesture, sometimes crossing his legs to show a ghost horse expression. Even the photographers who were filming couldn’t help but laugh, and the superhuman joy energy infected the scene.

Deng Chao and baby walk the red carpet


At the ceremony, Deng Chao, who met many friends, still maintained an excited mood, not only chatting non-stop off the stage, but also playing a humorous role on the stage. When it was announced on the spot that Deng Chao and Yang Mi were awarded the 2017 Weibo Night King & Queen respectively, Deng Chao waited for a moment at the entrance to the stage, and held Yang Mi on stage together in a very gentleman’s posture. However, it took only three seconds for the warm man to switch to the "talk" mode, praise his companions and say jokes frequently, and the live interaction was quite interesting.

Deng Chao won the 2017 Weibo Night King & Queen;

This year, "model worker" Deng Chao has also achieved double blossoming in the field of film and variety shows. The new season "Run" ranks at the top of the annual variety show topic ratings list. The joy energy of the super captain continues to release, and the national affinity index soars again. Two starring works have come out. The former plays a bohemian young man A Lang in a small town, and the latter is the sharp and wise detective Fang Mu. The two completely different roles not only make people feel the acting charm of Deng Chao again, but the box office 1.30 billion of the two films also adds a heavy weight to his personal cumulative box office and commercial appeal. In addition, Deng Chao won the Golden Rooster Award for Best Male Actor with his "unique and delicate psychological portrayal and strong character shaping skills" in the corner of Zhongxin Xiaofeng, which can be said to be deserved. The latest work was also completed in 2017. The film is the first time he has ventured into the theme of ancient costumes after many years, and has cooperated with Zhang Yimou for the first time. The performance of one person playing two roles has made Deng Chao accept huge challenges in physical shaping while investing in acting. He has completed the two processes of violent thinness and muscle growth in a short period of time, which has excited both inside and outside the industry.


[Ground Evaluation Line] Guisheng Online Comment： ＂Subject 3＂ goes out of the circle, and only by keeping the cultural roots can it move towards ＂long red＂

Dynamic music is accompanied by waving hands, twisting waist and hips, and half-twisted feet … During this period, the magic dance named "Guangxi Kemusan" is "out of the circle". Now this "subject three", which originated in Guangxi, has been "renovated" and created by netizens all over the country, and it has even spread through short videos. The "fire" is overseas and there are many circles.

Tracing back to the source,"Guangxi subject three"This dance is closely related to the living habits of Guangxi people, with a heavy cultural base. Speaking of Guangxi, the national carnival of "singing folk songs on March 3" and the snail powder of "smelling and eating incense" will first come to mind. As we all know, Guangxi people are also good at dancing. In this regard, it is rumored that "Guangxi people will experience three exams in their lives, one subject is singing folk songs, the other subject is rice noodles, and the third subject is dancing". In this way, this magical dance from Guangxi folk is called "subject three" "Fire" of "Guangxi Subject III"? Accidental with necessity. "Be the truest self" and "Happiness first" … These ideas conveyed by dance are infinitely close to the hearts of netizens. Although in the eyes of some netizens, "dynamic music+magical action" is a bit "earthy" or even a bit "non-mainstream", in the eyes of most people, this online cultural phenomenon is very interesting and has a cultural atmosphere.

I have to admit that "local flavor" culture has a great market among young people. Different from the traditional dance, the "subject three" mixed with burlesque performances can spread all over the world, driving more and more young people to participate in it, and many new "online celebrity" have emerged. Judging from the amplification of this phenomenon, there are many examples of "local flavor" culture setting off a "fashion style" in the Internet scene, which brought us joy and left a clear memory. For example, this year’s "digging, digging and digging" will explode all over the network. From children to "big friends", as long as the rhythm is turned on, most people will hum a few words; Looking ahead, the divine comedy "I’m from Yunnan and Yunnan Nujiang" also accidentally went off, and so on.

Some nonsense and earthy ideas have suddenly become popular on the internet, which is not unrelated to the multicultural needs of the online world. In the spiritual world of the Internet, a hundred flowers should have blossomed. The popularity of "Guangxi Subject III" is rooted in the cultural soil that Guangxi people can sing and dance well. With the spread of the Internet and the promotion of various eating places, it has achieved "coming out of the layer" and "breaking the circle", injecting new elements and vitality into the diversity and richness of online culture. Looking deep through this phenomenon, it itself reflects the cultural confidence of Guangxi people.

Only with culture and connotation can the roots be deeply rooted and become "long red". Whether "Guangxi Subject III" can achieve "long red" after leaving the circle depends on whether it has cultural connotation, whether it can arouse people’s spiritual resonance and stir up greater emotional resonance at a deeper level. Undeniably, many of the innovative ideas spread on the Internet, which are "popular" and "phenomenal", are difficult to "last forever", and some are even "short-lived", moving from a meteor to silence. However, "Guangxi subject three" is different from those niche ideas that suddenly "fire". The expression form of "subject three" is deeply integrated with the local dance in Guangxi, with distinctive regional characteristics and national symbols. However, what needs to be paid attention to is that in today’s information explosion era, the spread of network culture often lacks effective supervision and regulation, which requires preventing some commercialization and excessive speculation, keeping its roots and innovation, so as to help it grow healthily and continue to attract more netizens’ attention and pursuit.

The most important thing is that culture can reach the soul directly. The popularity of "Guangxi Subject III" network is also an opportunity for Guangxi to publicize and promote regional culture, national culture and historical culture. The local area should also dig deep into the cultural connotation and value significance behind it, incorporate more memorable and resonant innovative ideas, better protect and develop this distinctive network cultural phenomenon, and open up more "new ideas" and expectations.
