Abstract: In order to improve the optimization effect of new energy distribution network, the paper designs an optimization dispatching model of new energy distribution network based on improved particle swarm algorithm, simplifies the data collection process, improves the calculation efficiency, and the distribution network mode of new energy can be effectively identified by using the objective function and constraints, so as to effectively improve the frequency of power grid use and alleviate power shortage. The results show that the improved particle swarm algorithm can optimize the active power loss and voltage deviation effectively, and the overall satisfaction is over 0.950. So the improved particle swarm algorithm will be more and more widely used in optimization of new energy distribution network.
Keywords: improved particle swarm algorithm; new energy; distribution network; scheduling optimization
