CCTV.com News: The reporter learned from the Southern Power Grid that China's largest vehicle-network interaction was launched in the Southern Power Grid business area on March 28. More than 100,000 new energy vehicles participated in the interaction, and the interaction's electricity reached 500,000 kWh.
The five provinces and regions of Guangdong, Guangxi, Yunnan, Guizhou and Hainan simultaneously carried out vehicle-network interactions. In 63 cities, more than 100,000 new energy vehicles participated. This is the first time that such a large-scale car-network interaction has been carried out in the country, and it is also the first cross-provincial linkage.
Li Minhong, marketing director of the Southern Power Grid Company, said that the number of cities participating in the large-scale car-network interaction set a new record, with the interaction power exceeding 500,000 kWh. Through reverse discharge to the power grid, intelligent and orderly charging and invitation-filling and valley charging, the feasibility of car-network interaction in technology applications, business models, business format innovation and other scenarios has been fully verified. A demonstration sample is provided for the future, with cities as the main body, large-scale and sustainable development of vehicle network interaction, and the promotion of two-way charging and discharging of new energy vehicles.
The so-called car-network interaction is the new energy vehicle becoming a power bank, exchanging power with the power grid. During the trough of electricity consumption, the battery is charged in an orderly manner. During the peak of electricity consumption, the electrical energy in the battery is transferred to the power grid in reverse to provide power support. This method not only balances the grid load, but also brings economic benefits to car owners.
Hu Zechun, deputy director of the Institute of Power Systems of Tsinghua University, said that developing large-scale vehicle-grid interactions within the urban power grid can reduce the peak-to-valley difference of urban power grids and reduce the investment in the corresponding power grids and power supplies of urban power grids, so it can become an important resource for the power system to ensure the safe and stable operation.
