The continuous growth of renewable energy power generation led to heated discussion on how to achieve reasonable consumption. Release date: Source: Economy - China's economy
with the strong rise of renewable energy such as photovoltaic and wind energy, China's economic growth mode is changing towards green and low-carbon. This year, energy efficiency has been written into the government work report, and its strategic position has become increasingly prominent
the 2021 government work report clearly pointed out that strengthening the national economic security, implementing the strategies of grain, energy resources and financial security, maintaining the comprehensive grain production capacity at more than 1.3 trillion Jin, and improving the comprehensive energy production capacity. We will comprehensively improve public security and safeguard social stability and security
during the two sessions, many representatives and members made their own voices around the "3060" carbon target to achieve the healthy development of renewable energy and improve energy security
Liu Han, deputy to the National People's Congress and chairman of the board of directors of Tongwei group, believes that the gradual increase in the penetration of renewable energy on the power side requires electricity to synchronously improve the real-time balance and peak shaving ability of the flat system of the test piece in the experimental process, so as to ensure the effective consumption of renewable energy
in the face of the new challenges brought by new energy to the power system, the head of the power safety supervision department of the National Energy Administration admitted in an interview with China power news that China's energy and power industry has changed from fossil energy to renewable energy. The power system presents the "double high" characteristics of high renewable energy and high proportion of power electronic equipment, and the operation characteristics of the power system are becoming more complex. At the same time, "With the increasingly frequent and violent extreme weather, the volatility and intermittent characteristics of new energy will be amplified, and the difficulty of real-time power balance will further increase"
according to the statistics of the national energy administration, by the end of 2020, the installed capacity of renewable energy power generation in China had reached 934million kW, an increase of about 17.5% year-on-year
with the continuous growth of renewable energy power generation, how to avoid "abandoning light and electricity" and realize the reasonable consumption of power system has become a top priority. Liu Han suggested, "in combination with the development trend of energy storage technology, China should fully consider the positive externalities of energy storage in promoting renewable energy consumption and improving electrical stability in future policy-making, design a reasonable energy storage price compensation mechanism and market access mechanism, continue to optimize the development mode of energy storage, and help the high-quality development of renewable energy."
Zeng Yuqun, member of the CPPCC National Committee and chairman of Ningde Times New Energy Technology Co., Ltd., also believes that electrochemical energy storage should be incorporated into national and local energy development plans, power development plans and renewable energy plans as a new national infrastructure to support the implementation of the national "3060" strategic goals
in the guiding opinions on promoting the integration of power source, load and storage and the complementary development of multiple energy issued by the national development and Reform Commission and the National Energy Administration on March 5, it is clearly proposed to use the existing conventional power supply, reasonably allocate energy storage, coordinate the planning, design, construction and operation of all kinds of power supply, give priority to the development of new energy, actively implement the improvement of the stock "integration of scenery, water, fire and storage", and steadily promote the incremental "integration of scenery, water and storage", Explore the incremental "integration of scenery and storage" and strictly control the incremental "integration of scenery, fire and storage"
in fact, Hunan electric power has made effective attempts. Meng Qingqiang, a deputy to the National People's Congress and chairman of Hunan Electric Power Co., Ltd., said, "we focus on the research of battery energy storage planning, focusing on the key issues of energy storage planning, merging, operation, business model and so on". In addition, we have also established the electric energy storage Professional Committee of Hunan Institute of electrical engineering to formulate the energy storage access system and relevant regulations, and clarify the relevant technical requirements. Meng Qingqiang revealed that in 2019, Hunan Electric Power Co., Ltd. has completed the first phase of battery energy storage demonstration project. Since the project was launched, it has signed cooperation contracts with a number of companies for wind power supporting energy storage leasing services, actively promoting the wide application of the "new energy + energy storage leasing" business model without impact. At the same time, guide social capital to participate in the construction of energy storage power stations
at this stage, strengthening the flexible regulation role of the power side, giving play to the regulation capacity of energy storage facilities, reducing the peak shaving pressure of the sending and receiving end system, and maintaining the comprehensive utilization rate of all kinds of renewable energy at a reasonable level are the effective ways to actively build a clean, low-carbon, safe and efficient new power system and promote the transformation and upgrading of the energy industry
