Largest Vehicle-Grid Interaction Demonstration Area in China Officially Goes into Commercial Use
TapTechNews July 11th news, according to CCTV News, the largest vehicle-grid interaction demonstration area in the country - the Jiangsu Wuxi vehicle-grid interaction demonstration area was officially put into commercial use yesterday.
What is called vehicle-grid interaction means that through the charging pile, new energy vehicles can conduct two-way charging and discharging with the power grid. While allowing car owners to obtain corresponding benefits, it also alleviates the power supply pressure during the peak electricity consumption period.
New energy car owner Zhu Shixin said: Usually I charge at home, and one kilowatt-hour costs more than 30 cents. Here, discharging can get a 3-fold points reward, which can offset the charging cost, which is quite cost-effective.
It is reported that the first phase of this demonstration area includes 59 vehicle-grid interaction charging and discharging piles, and the maximum charging and discharging power per pile can reach 60 kilowatts. In the demonstration area, car owners can click the discharge button in the mobile phone applet to reverse charge the power grid. In the morning of the same day, a total of more than 50 new energy vehicles of different brands discharged to the power grid, and the cumulative discharged electricity exceeded 3100 kilowatt-hours.
TapTechNews noticed that the National Development and Reform Commission, the National Energy Administration, the Ministry of Industry and Information Technology, and the State Administration for Market Regulation released the Implementation Opinions on Strengthening the Integration and Interaction between New Energy Vehicles and the Power Grid in January this year, and put forward a series of tasks and goals for vehicle-grid interaction, two-way charging and discharging of new energy vehicles, etc.
The development goals mentioned in the Opinions point out that by 2025, the technical standard system of vehicle-grid interaction in China will be initially established, the peak-valley electricity price mechanism for charging will be fully implemented and continuously optimized, important progress will be made in the construction of market mechanisms, and vehicle-grid interaction pilot demonstrations will be carried out with greater efforts. It is力争 that in the cities participating in the pilot demonstration, more than 60% of the charging electricity throughout the year in 2025 will be concentrated in the off-peak period, and more than 80% of the private charging pile charging electricity will be concentrated in the off-peak period. The potential of new energy vehicles as a mobile electrochemical energy storage resource will be initially verified through pilot demonstrations.
By 2030, the technical standard system of vehicle-grid interaction in China will be basically established, the market mechanism will be more perfect, vehicle-grid interaction will achieve large-scale application, and intelligent and orderly charging will be fully promoted. New energy vehicles will become an important part of the electrochemical energy storage system, and it is力争 to provide the power system with a two-way flexibility adjustment capacity of tens of m illions of kilowatts.
