Effectively promote the supply and demand balance of the power grid, and the capacity of the virtual power plant is not "virtual"
2022-08-19
Since the beginning of summer, high-temperature weather above 35 ℃ has occurred in many parts of the country, and high temperatures have occurred continuously in many cities. The economic recovery is superimposed on the high-temperature weather, the power load in China is growing rapidly, and the virtual power plant has frequently entered the public's view. Since the beginning of this year, the "14th five year plan" for modern energy system issued by the national development and Reform Commission and other departments, as well as the "14th five year plan" for energy and power development and the carbon peak implementation plan issued by more than 10 provinces including Tianjin, Beijing and Shanghai, have put forward clear requirements for the development of virtual power plants. The state is stepping up the layout of virtual power plants. What is a "virtual power plant"? "The virtual power plant is not a power plant, but an energy management system. It is installed in the control terminals of large power users such as factories. It integrates interruptible loads such as air conditioning and lighting into the control sequence, and achieves supply and demand balance through accurate control without affecting the normal production of enterprises." Said Yang Kun, executive vice president of China Electric Power Enterprise Federation. The relevant person in charge of the National Energy Administration said that reducing the load through demand side response will have a better effect on the development of the entire power industry. The "14th five year plan" for modern energy system further proposes to carry out the demonstration of virtual power plants integrating various resources such as industrial adjustable load, building air conditioning load, big data center load, user side energy storage, new energy vehicles and grid energy interaction. In October 2021, the State Council issued the action plan for reaching the carbon peak by 2030, which proposed to vigorously improve the comprehensive regulation capacity of the power system, speed up the construction of flexible regulation power supply, and guide self-contained power plants, traditional high load industrial loads, industrial and commercial interruptible loads, electric vehicle charging networks, virtual power plants, etc. to participate in system regulation. Yang Kun, who aims to improve the consumption capacity of new energy, said that as a new business form and new mode of energy intelligence, virtual power plants have broad application prospects. Under the background of the transformation of power grid structure to clean and low-carbon, the development of virtual power plants has important practical significance to promote the balance of power grid supply and demand, realize low-cost grid connection of distributed energy, fully absorb clean energy generation, and promote the transformation of green energy. In August 2021, the national key research and development project undertaken by the State Grid Jiangsu Electric Power Co., Ltd. -- the friendly interaction system between urban users and power grid supply and demand passed the acceptance, extending this precise load control mode to the residential power consumption side, which can achieve the purpose of "cutting peak and filling Valley" and maintaining the balance of power supply and demand. Yuan Yubo, chief engineer of the Electric Power Research Institute of the State Grid Jiangsu Electric Power Co., Ltd., said that the virtual power plant can suppress the strong random fluctuation of new energy power, improve the utilization rate of new energy, aggregate, optimize control and manage a variety of distributed energy, and provide auxiliary services such as frequency modulation and peak shaving for the power grid. At present, relevant enterprises have accelerated their layout. North China Power Grid took the lead in carrying out the transaction of virtual power plants participating in the auxiliary service market in China. The smart virtual power plant platform of State Grid Zhejiang comprehensive energy company was launched, and the virtual power plant platform of state power investment Shenzhen Energy Development Co., Ltd. participated in the transaction of power spot market. The market prospect of virtual power plant is promising. Many people in the industry pointed out that the current virtual power plant is still in the initial stage of development. Wang Peng, executive director of the National Energy Development Strategy Research Institute of North China Electric Power University, said that
