Research on Reactive Power Optimization of High Proportion New Energy Access Distribution Network Based on NSGA-III Algorithm

A reactive power optimization model with the objective of minimizing voltage offset and network loss is established from a comprehensive consideration of the safety and stability of the operation of high-occupancy wind power and PV connected to the grid. MATLAB software is used to simulate and analyze the reactive power optimization of wind power and PV power plants connected to the IEEE33 node system, and the multi- NSGA-III algorithm is used to solve the reactive power optimization scheduling scheme. The NSGA-III algorithm based on the Pareto front solution can provide solutions for decision makers according to different demands, and simultaneously achieve the objectives of improving the voltage stability of the tested system and reducing the network loss, which verifies the effectiveness of the proposed optimization strategy.
