Original title: New energy vehicles reversely supply electricity to the power grid Chongqing carries out large-scale vehicle-grid interactive application for the first time
Chongqing, August 25 (Xinhua) (Reporter Huang Xing) Chongqing has been experiencing continuous high temperatures and sunny weather recently, and the power load has risen rapidly. In order to further enhance Chongqing's power supply capacity during the peak summer season and enrich the means of power supply, Chongqing launched a large-scale vehicle-grid interactive application for the first time on the evening of the 24th, guiding new energy vehicles to participate in peak-shifting charging, V2G reverse discharge, and access to virtual power plants, helping the power grid to reduce peak loads.
It is understood that V2G is the reverse transmission of electricity from new energy vehicles to the power grid. New energy vehicle owners can obtain corresponding economic benefits by discharging electricity to the power grid through V2G piles, and can help reduce the peak load of the power grid. On the evening of the 24th, a total of 120 new energy vehicles participated in the V2G large-scale reverse discharge pilot application. The discharge lasted for 2 hours, with a total reverse discharge of more than 1,700 kWh, which can meet the electricity needs of more than 420 residential users for 1 hour.

In order to cope with the peak electricity consumption, Chongqing Power Department also relies on the valley electricity price policy to guide new energy vehicle owners to charge in the valley period, helping the power grid to shift peak loads. On the evening of the 24th, a total of 75,600 new energy vehicles in Chongqing participated in peak charging during the valley period of the power grid load, and at most more than 260,000 kilowatts of load were given up during the peak electricity consumption period. At the same time, there are 88 charging piles participating in the peak load reduction of the power grid through the virtual power plant model, reducing the peak load of the power grid by nearly 10,000 kilowatts.

"Through this large-scale vehicle-grid interaction application, it not only helps to reduce the peak load of the power grid and help the power grid safely meet the peak load in summer, but also verifies the effectiveness of the integrated interaction between new energy vehicles and the power grid, laying the foundation for Chongqing to carry out larger-scale vehicle-grid interaction in the future, and will better assist Chongqing in building a super-charging convenient city." The person in charge of the Market Department of the Marketing Department of State Grid Chongqing Electric Power Company said.
