天津“车网互动”实现百兆瓦级突破

Core Insights - The "Car-Grid Interaction Demonstration Month" in Tianjin successfully showcased the potential of electric vehicle (EV) charging infrastructure, achieving peak shaving and valley filling capabilities of 137.4 MW and 139.7 MW respectively, equivalent to adding a 100 MW "power bank" to the grid [1] - The event was guided by the Tianjin Municipal Development and Reform Commission and led by State Grid Tianjin Electric Power Company, aggregating over 50,000 charging piles and involving approximately 15,000 vehicles, resulting in a peak load reduction of about 320,000 kWh and saving EV owners around 160,000 yuan in charging costs [1] - The initiative involved collaboration with 19 charging and battery swapping operators to create a "Car-Grid Interaction" system covering various charging scenarios, with virtual power plants playing a crucial role in stabilizing the grid by aggregating distributed energy resources [1] - The virtual power plant in Tianjin has aggregated six types of resources, including charging stations, photovoltaics, and energy storage, with a total capacity of 316 MW [1] - The event is seen as a milestone in implementing national pilot tasks and building a new power system, providing practical support for replicable and scalable "Tianjin experience" [2] Industry Developments - As of June 2023, the number of electric vehicles in China reached 36.89 million, accounting for 10.27% of the total vehicle population, indicating the growing potential of EVs as "mobile energy storage units" [2] - The successful validation of the "Car-Grid Interaction" model demonstrates its scalability and the feasibility of its technology and business model [2]
