Abstract
With distributed photovoltaic (DPV) connected to the distribution network, distribution network faces new challenges. The distribution network needs to dynamically adjust the switch state of branches in order to deal with the fluctuation of DPV output, but the original static reconfiguration cannot satisfy the requirements. Therefore, this paper proposes a method of distribution network with DPV dynamic reconfiguration based on information entropy time division and Binary Particle Swarm Optimization (BPSO) algorithm. Firstly, this paper describes the concept and existing research methods of reconfiguration. And the power flow calculation method loop impedance method and its related concepts are described. Secondly, it introduces the method of time division using information entropy, which can divide the equivalent daily load curve more accurately and reasonably. Then, BPSO is applied in dynamic reconfiguration of distribution network. The program is compiled by MATLAB R2021a. The simulation results of IEEE33 with DPV distribution system shows that the proposed method is effective and rational.
