摘要(Abstract)：

大规模光伏发电接入配电网会使系统节点电压抬升，严重情况下将出现电压越上限问题。为此，提出了基于并联和串联电抗器以及遗传算法的调压策略。首先分析了配电网电压抬升的原因以及并联电抗器和串联电抗器在电压调整中的作用。然后，建立以经济最优为目标的无功优化模型，并利用遗传算法求解电抗器优化配置方案。最后，基于MATLAB仿真平台对并入大功率光伏电站的IEEE 33节点系统进行仿真，验证了方法的有效性。
Large-scale photovoltaic power connected to the distribution network will raise the voltage at the system nodes,and,in serious cases,the voltage overlimit. Therefore,a voltage regulation strategy based on shunt and series reactors as well as genetic algorithm is proposed. Firstly,the causes of voltage rise in the distribution network and the roles of shunt and series reactors in voltage regulation are analyzed. Then,a reactive power optimization model with the objective of economic optimization is established,and the genetic algorithm is used to solve the optimal reactor configuration scheme. Finally,the effectiveness of the method is verified by simulating the IEEE 33-node system incorporated into a high-power PV plant based on the MATLAB simulation platform.
