Evaluation on Power Supply Ability of Unbalanced Three-phase Distribution Network with Three-phase Unbalance of Distributed Generation
摘要
Abstract
With connection of distributed generations (DGs)especially connection of those intermittent DGs such as photo-voltaic (PV),inherent feature of three-phase unbalance of the power distribution network has become more and more prom-inent. Therefore,this paper discusses the evaluation method for power supply ability of the power distribution network with three-phase unbalance of DG. It firstly presents a kind of evaluation method for power supply ability of the distribution net-work with multiple three-phase unbalance of DGs which aims at the maximum of power supply load of the distribution net-work and considers constraint conditions such as load growth power factors and three-phase unbalance degree of the node at the same time. Secondly,it solves the problem of power supply ability of the power distribution network based on the quan-tum-behaved particle swarm optimization algorithm,and encodes continuous and discrete particles according to probabilities of quantum bits. By adopting the quantum rotation gate and integration method,it can respectively realize updating of con-tinuous particles and discrete particles so as to improve searching precision. In addition,by means of quantum NAND gate, it can realize variation of particles so as to avoid prematurity phenomenon and improve global searching ability and optimiza-tion efficiency of the algorithm. Finally,it makes simulation on power supply ability of the distribution network based on modified IEEE-33 three-phase unbalanced distribution network. Corresponding results prove effectiveness of the model and method.关键词
