天津“车网互动”实现百兆瓦级突破 验证规模化应用可行性

Core Insights - The "Vehicle-Grid Interaction" initiative in Tianjin has successfully demonstrated the feasibility of large-scale applications, achieving a peak load response capability of 137.4 MW and 139.7 MW for peak shaving and valley filling scenarios respectively, equivalent to integrating a 100 MW "charging treasure" into the grid [1][2] Group 1: Event Overview - The initiative was guided by the Tianjin Municipal Development and Reform Commission and led by the State Grid Tianjin Electric Power Company, aggregating over 50,000 charging piles and involving approximately 15,000 vehicles [1] - The event resulted in a peak load reduction of about 320,000 kWh, saving vehicle owners approximately 160,000 yuan in charging costs [1] Group 2: Technological and Operational Insights - The "Vehicle-Grid Interaction" system was developed in collaboration with 19 charging and battery swap operators, covering various scenarios including public charging stations and community charging piles [1] - The virtual power plant technology played a crucial role by aggregating dispersed power resources via the cloud, ensuring stable grid operation, with a total capacity of 316 MW from six types of resources including charging stations, photovoltaics, and energy storage [1] Group 3: Industry Implications - The initiative is seen as a significant milestone in implementing national pilot tasks and constructing a new power system, providing practical support for replicable and scalable "Tianjin experience" [2] - The potential of electric vehicles as "mobile energy storage units" is gradually being realized, with the total number of electric vehicles in China reaching 36.89 million by the end of June, accounting for 10.27% of the total vehicle ownership [2]
