摘　　要：从传统的负荷侧挖掘电网运行潜力,分析电网友好型微网响应电网运行需要的能力。通过微网内各类分布式电源的优势互补,发挥电动汽车的移动储能功能消纳随机性电源出力波动性,使微网出力在一定范围内具有可伸缩性。建立了微网经济运行模型,分析微网响应外部系统负荷特性的能力。算例结果表明微网在协调各类电源出力的方式下可消纳其内部间歇性电源,并能良好地完成系统调度计划,可调度性潜力巨大。The paper analyzes the ability of grid-friendly based microgrid responding to power grid operation demand by exploiting the potentialities of the grid operation from the traditional load side, balances the DG output uncertainties by controlling EV charging and discharging, and makes the microgrid output scalable through coordinating all kinds of DGs. Moreover, the paper establishes a microgrid economic operation model to analyze the load response ability of the microgrid. The simulation result shows that the microgrid can absorb internal intermittent power generation, execute a system dispatching well by coordinating various power supplies and has great potential of the dispatching.
