Core Insights - The article discusses the increasing demand for electricity due to heatwaves, leading to a peak in energy consumption and the implementation of virtual power plants and pumped storage to stabilize the grid [1][3]. Group 1: Virtual Power Plants - In Sichuan, the first "orderly charging and discharging" virtual power plant has been launched, allowing residents to charge their electric vehicles during off-peak hours and discharge during peak hours, benefiting from free charging [3][4]. - Sichuan has established 30 virtual power plants and 295 energy storage projects, with a total adjustable capacity exceeding 1 million kilowatts [4]. Group 2: Electricity Demand and Response - Wuhan's electricity load has reached a historical peak of 17.8681 million kilowatts, prompting the local virtual power plant management platform to conduct precise responses in high-load areas [4][6]. - A textile company in Wuhan adjusted its production schedule during peak hours, receiving approximately 40,000 yuan in response subsidies [4]. Group 3: Market Mechanisms and Performance - The actual response from users was about twice the targeted response, demonstrating the effectiveness of the market-driven mechanism of virtual power plants in guiding electricity load [6]. - Guangdong's electricity load has reached a record high of 164 million kilowatts, with six pumped storage power stations providing 1.936 million kilowatts of adjustment capacity, enhancing the grid's regulation capability by over 10% [6][8]. Group 4: Energy Management - The number of full-capacity operations of 31 units in the Greater Bay Area has significantly increased compared to last year, with a single-day maximum adjustment of over 100 million kilowatt-hours, equivalent to the daily electricity demand of 16.6 million residents [8].
