Reactive power optimization in distribution network considering seasonal load changing

This paper presents a reactive power optimization method considering seasonal load changing based on a two-year project. Data of lines, transformers and seasonal load were taken into account to create a simulation model. By taking the moment when the load is maximum in each season, flow of the distribution network was calculated. The calculation results were closer to the actual measurement results. Based on Genetic algorithm, four reactive compensation plan along with seasons were got. The paper got a best project Considerating the line losses, Voltage qualification rate and bus voltage Security. The best reactive power optimization result can significantly reduce the distribution network losses and improve voltage qualification rate.
