摘    要:针对大量间歇性分布式电源接入微电网带来的冲击,提出了需求响应定义新延伸,将频率控制纳入需求响应的范畴。同时提出了将需求响应分为用户需求响应和电网需求响应的模式,分析了电网需求响应对平抑间歇性电源的冲击,提高微电网稳定性的显著作用。分析了将电动汽车充电站作为需求响应的主要可控负荷比作为分布式电源看待更具现实可行性。提出了将电动汽车充电站作为电网需求响应对象的更加经济的运行控制策略,并在Matlab/Simulink仿真平台上搭建了该微电网模型。通过算例仿真对比,验证了在微网孤岛运行时该控制策略出色的调频性能以及面对大波动下微网表现出的良好稳定性。

关 键 词:需求响应;电动汽车;微电网;稳定性

Abstract:For the impact of a large number of intermittent distributed power connecting to micro-grid, this paper proposes a new extension of demand response definition and takes frequency control into the area of demand response. Meanwhile, demand response is divided into user demand response and grid demand response. The impact of grid demand response on stabilizing intermittent power and its significant role in improving the micro-grid stability are analyzed. It analyzes that taking charging stations of electric vehicle as a main controllable load of demand response has more realistic feasibility than as a distributed generation. A more economic operational control strategy which regards the electric vehicle charging station as a grid demand response object is proposed and the micro-grid model is built on Matlab/Simulink simulation platform. By simulation comparison, in the micro-grid islanding operation, it verifies that this control strategy has excellent performance of FM and good stability when it faces large fluctuations of micro grid.
Keywords:demand response   electric vehicle   micro grid   stability
