Research on Protection Optimization of Distribution Network Containing Distributed Power Generation Based on Sparrow Algorithm

Abstract

Abstract In recent years, the increasing energy crisis and environmental pollution have brought attention to distributed renewable power generation such as photovoltaics and wind power. However, the integration of distributed power sources puts forward higher requirements for the safety, stability and economic operation of the power system. Traditional protection setting methods face greater difficulties in solving the contradiction between action time and protection selectivity under complex conditions including distributed power generation. In many cases, the setting value is not optimal. With the increase in the penetration rate of distributed power sources and the increasingly complex operation of distribution networks, how to achieve the optimal setting of overall protection performance has become a current research hotspot. For this reason, this paper proposes a new scheme based on the Sparrow algorithm to optimize the online protection of distributed power distribution network protection, which is verified by a calculation example.
