Study on Reactive Power Optimisation of Distribution Network Containing Photovoltaic Power Generation
China vigorously develops and builds photovoltaic power generation technology.However,the distribution network of PV power generation contains a large amount of reactive power,which makes the power factor of the system very low,so it is necessary to carry out reactive power optimisation studies on the distribution network containing PV power generation to improve the security,reliability and economy of the grid.Based on the IEEE33 node system for reactive power optimisation analysis of PV distribution networks,a particle swarm algorithm is used,with active network loss optimisation as the objective function,in which the current calculation part is performed by using the forward back generation method,with active power,reactive power and voltage magnitude as the constraints.Finally,the feasibility and effectiveness of the algorithm is verified through simulation by comparing the network loss before and after access.
