Multi-objective optimization strategy of islanding microgrid based on improved NSGA-II algorithm

Abstract

Abstract Aiming at the microgrid system with distributed energy sources such as wind, diesel generator, and fuel cell and flexible load in islanding mode, the optimal dispatching model is established to consider the optimal load and reduce the economic cost. This study adopts the improved NSGA-II algorithm, which can improve the optimization efficiency and get the optimal solution better. The simulation analysis of the microgrid in the islanded mode is carried out within a cycle of 24 h. The results of the model show that this strategy can effectively optimize the load curve and reduce the current cost of supply.
