[Chinese Academy of Electrical Sciences: China's electricity demand response ratio will increase fourfold from 2030 to 2060] the largest fluctuation of new energy in the national network has reached 250 million kilowatts a day, equivalent to the electricity consumption of the whole of North China. " Geng Jian, director of the optimal dispatching Research Office of the Institute of Electric Power Automation of the Chinese Academy of Electrical Sciences, said at the 2023 Virtual Power Plant and Power Market Development Forum that with the continuous increase in the proportion of new energy generation, its intermittent and fluctuating characteristics are more obvious. coupled with the replacement of conventional power sources by new energy, the overall regulation capacity of the power grid system shows a downward trend, so there is an urgent need to awaken the massive load side resources and promote the coordination and interaction of load and storage in the source network. According to the analysis of the source load balance of the new power system by the Chinese Academy of Electrical Sciences, the power demand response ratio will reach 5% in 2030, 10% in 2045 and 20% in 2060.
