摘　　要：为了提高光伏电源逆变器并网对配电网电压的影响,并给出合理的分布式光伏并网规划方案,针对输出电能稳定性建立双环控制策略,利用仿真软件PSCAD/EDC进行了建模和仿真并以此组建了整个光伏微电网系统模型。用双环控制对控制策略进行了优化,使光伏发电系统进过逆变器输出功率最大。通过仿真实验,该仿真分析结果可为光伏发电控制系统系统优化及规划建设提供科学的参考依据。In order to improve the impact of grid-connected photovoltaic power supply inverters on the voltage of distribution network, a reasonable distributed photovoltaic grid-connected planning scheme is proposed. A dual-loop control strategy is established for the stability of output power. The whole photovoltaic micro-grid system model is established by using simulation software PSCAD/EDC. The control strategy is optimized with double-loop control to maximize the output power of photovoltaic power generation system through the inverter. Through simulation experiments, the simulation results can provide a scientific reference for the optimization and planning of photovoltaic power generation control system.
