山东首次“车网互动”居民V2G桩集群放电在淄博完成

Core Viewpoint - The successful implementation of a "residential V2G charging pile cluster discharge scenario verification" in Zibo, Shandong Province, marks a significant step in exploring community electricity security through resident participation in emergency power supply [1][5]. Group 1: Implementation and Results - The verification involved 7 V2G charging piles with a peak output power of 49 kW, successfully powering essential loads such as an 18.5 kW fire fan and 16 kW emergency lighting [2]. - A 30 kW/60 kWh energy storage system was also configured to ensure the continuity of emergency power supply, providing voltage stabilization and dynamic balance [2]. - The smart energy management platform monitored the discharge process, confirming stable voltage and current, achieving the expected verification goals [2]. Group 2: Technology and Mechanism - The V2G technology enables bidirectional energy flow between electric vehicles and the grid, facilitating smart and orderly charging and discharging [3]. - The pricing mechanism for cluster discharges is based on the weighted average electricity price from the real-time market in Shandong [3]. Group 3: Future Prospects and Developments - Zibo is recognized as one of the first cities in China to implement large-scale "vehicle-grid interaction," setting a new standard for enhancing emergency resilience in power distribution networks [5]. - The company plans to reduce the cost of residential V2G charging piles through collaboration with technology firms and aims to establish 7 public V2G demonstration stations [6]. - Future incentives and improved market mechanisms are expected to expand the development space for "vehicle-grid interaction," contributing to community and societal power supply security [6].
