Abstract

After the integration of distributed photovoltaics, the active distribution network is prone to significant voltage fluctuations and high failure rates. Therefore, a new method for optimising the capacity of the active distribution network is studied. Firstly, under distributed photovoltaic access, an active distribution network power model is constructed from three aspects: wind power model, photovoltaic model, and energy storage system model. Secondly, with the goal of minimising the annual cost and daily operating cost, construct an active distribution network capacity optimisation configuration objective function. Finally, the particle swarm optimisation algorithm is used to obtain the optimal solution of the objective function and complete the active distribution network capacity optimisation configuration. The analysis of experimental results shows that under the optimised configuration of the method proposed in this article, the fault rate of the active distribution network is significantly reduced, and the voltage stability is improved.
