Research of distribution network reconfiguration with renewable energy power generation unit

In order to make the high permeability of renewable energy of distribution network reconfiguration work more practical and effective, this paper put forward a new model which can absorb wind and photovoltaic generation. Firstly, we setup the mathematical model of renewable energy power generation unit which conclude wind and photovoltaic power generation, and made the output of wind and photovoltaic power generation discretization, divide a day time into three reconfiguration partition depend on load characteristic. Secondly, improve the basic genetic algorithm about chromosome coding method, reduce the initial population of infeasible solution vector space, and adaptively regulates the crossover ratio and mutation ratio during optimization process, improve the speed and effect of the optimization algorithm. Finally, using the improved genetic algorithm to distribution network reconfiguration optimization of each reconfiguration partition. Through the simulation analysis was carried out on the modified IEEE-33 system, verify the correctness and effectiveness of the proposed method.
