Reactive power optimization of distribution network with photovoltaic power based on sparrow search algorithm

Abstract

With the construction of new power systems centered around new energy, distributed photovoltaic power generation has been rapidly popularized. Photovoltaic power generation with volatility and randomness is connected to the distribution network, causing voltage fluctuations in the distribution network to exceed allowable values and an increase in system losses. The objective of this article is to establish a mathematical model for optimizing the distribution of reactive power using distributed photovoltaic power generation, to minimize system losses and voltage fluctuations. Using an improved sparrow search algorithm to solve the model and taking the IEEE30 node system as an example for simulation analysis, the feasibility of the model and algorithm is verified through case analysis.
