As part of the test, all provinces will be asked to nominate one city to create V2G system.
Regions with more mature infrastructure, such as the Yangtze River Delta, the Pearl River Delta, the Beijing area and Sichuan Province, can nominate two cities to participate, the commission said. Each province can recommend up to five V2G projects, according to the directive.
What is Vehicle to Grid (V2G)?
V2G is a system that enables bidirectional energy flow between the power grid and an electric vehicle.thanks to which car batteries act as stores of electrical energy collected during periods of low demand and fed into the grid during periods of peak demand.
In addition, during periods of high generation of renewable energy sources, the system receives surplus energy produced by RES.
The aim of the Chinese test is to scale up V2G projects and explore commercial models that can be replicated, according to a document published by the National Development and Reform Commission.
Fluctuating energy prices
The regions where the test will be conducted should fully implement electricity pricing with high peak demand and lower demand for low demand, which is to be concentrated at least 60 percent of electric vehicle charging during off-peak hoursthe commission said. In contrast, the percentage of off-peak charging for electric vehicles via private chargers, should be at the level of at least 80 percent.
Nearly 25 million electric cars and potential energy storage
China’s electric car fleet is growing rapidly, with sales of battery-powered and hybrid cars outpacing sales of gasoline cars in each of the past two months. In the first half of 2024, the number of battery-powered vehicles reached 24.72 millionwhich accounts for about 7 percent of all cars on Chinese roads, Bloomberg notes.
Without proper management, charging such a large fleet of vehicles could increase energy demand and overload the grid, the agency said. But if done properly, electric vehicles can also store energy that can be fed back into the grid when needed.
In the first half of the year, demand for electricity to charge electric vehicles rose 64% year-on-year, the China Electricity Council said in July.
