استراتژی ترمیم قدرت برای شبکه توزیع بر اساس روش نقطه ایده آل وزنی

A power restoration strategy for the distribution network based on the weighted ideal point method is proposed in this paper. First, with the power loss, voltage quality and load balancing as the reconfiguration goal, the comprehensive evaluation function is established. And then, the rough set theory is used to calculate the weight coefficients of the sub-objective functions. Finally, the optimal solution of the comprehensive evaluation function is obtained by applying the ideal point method. Simulation tests on the 33-bus and 69-bus radial distribution networks verify that, the proposed method of using multi-objective function instead of single objective function to gain the optimal solution is more comprehensive in different considerations and more in line with the requirement of the actual distribution network power restoration. Furthermore, the uncertainty problem in traditional weight setting due to dependence on experience can be avoided.
