考虑电动汽车空间分配的多目标配电网重构优化
Multi-objective optimization of distribution network reconfiguration considering the spatial allocation of electric vehicles
摘要
Abstract
The disorder of electric vehicles charging process in space will greatly influence the distribution network reconfiguration.On the premise of tending to choose the station of shortest distance and least time for users of electric vehicles , a multi-objective optimization model of distribution network considering space allocation of electric vehicles was established in this paper .This model chose network loss and voltage deviation level as optimization goal with utili-ty degree of the electric vehicles as constraint condition to optimize the network switch state and electric vehicles char -ging load space allocation at the same time .The fuzzy C-means clustering was adapted to cluster electric vehicles in the system according to the spatial index , and the electric vehicles in the similar position of spatial allocation were gathered the same clustering , thus reducing the dimension of the model effectively .Finally, the model is solved by the improved genetic algorithm to obtain an integrated optimization scheme .The simulation results show that the fuzzy C-means clustering can significantly reduce calculation difficulty and improve the convergence rate of the algorithm , be-sides, with the guidance of the reconstructed model , the grid ensured its operation economy and reliability , reducing the electric vehicle charging time and distance , as a result , the validity of the model and method is proved .关键词
