Xinhua News Agency, Hangzhou, August 21 (Reporter Lin Guangyao) The reporter learned from State Grid Zhejiang Electric Power Co., Ltd. that this summer, Zhejiang Province has a total of 33,000 public charging piles in the form of virtual power plants to help the power grid shift peak loads. Various charging facilities such as bus charging piles, V2G charging piles, and private charging piles are concentratedly involved in vehicle-grid interaction.

Among them, from August 5 to 8, Zhejiang Car-Grid Interaction responded to a total of 1.63 million kWh of electricity and achieved a maximum peak load reduction of 115,300 kW, providing the power grid with more than 100,000 kW of flexible load regulation capacity.

In terms of bus charging piles, in Quzhou City, Zhejiang Province, the Quzhou Bus Group uses the charging management platform to adjust the original charging tasks during peak hours to off-peak hours, helping the power grid to shift peak loads.

At the same time, it has become a new trend for new energy vehicles to interact with the power grid through V2G charging piles. Recently, in Xiaoshan District, Hangzhou, Zheng Cheng, a new energy vehicle owner, experienced the "charge-discharge-swap" vehicle-grid interactive application. By using the State Grid's "e-charging" App and a 60-kilowatt V2G charging pile, he "fed back" the remaining 60 degrees of electricity in the car's battery to the power grid, helping the power grid to reduce peak loads while also earning the difference between peak and valley electricity prices.

In addition, in terms of private charging piles, a total of 406,000 new energy vehicle owners in Zhejiang participated in the "One Hour Later Charging" activity this summer, reserving the charging time to after 11 pm, and shifting the charging load back by more than 500,000 kilowatts per day. (End)
