含光伏接入的过电压时序递进无功优化方法研究

Study on over voltage sequential progressive reactive power optimization with photovoltaic access

近年来光伏发电得到了国内外大范围的使用,光伏发电并入电网后,易造成配电网的电压波动较大,电网及其不稳定。本文针对这一现象,重点论述了光伏发电的原理与组成,利用改进的遗传算法对光伏接入后的电压进行无功优化。

In recent years,photovoltaic power generation has been widely used at home and abroad.After photovoltaic power generation is incorporated into the power grid,it is easy to cause large voltage fluctuation of the distribution network and instability of the power grid.Aiming at this phenomenon,this paper focuses on the principle and composition of photovoltaic power generation,and uses the improved genetic algorithm and annealing fish swarm method to optimize the voltage after photovoltaic connection.
