Research on distribution network fault recovery method with micro-grid based on improved BPSO algorithm

针对配电网中微网的接入使故障恢复需要考虑的安全因素更多,目前的故障恢复方法存在计算量大、故障恢复时间长等问题。以最小网损、最少开关动作次数和最少失电量为目标函数建立了含微网的配电网故障恢复模型,并将改进的二进制粒子群算法和遗传算法相结合用于模型求解。对多种故障恢复情况进行分析,验证了该故障恢复方法的可行性。结果表明,相比于传统恢复方法,所提方法收敛速度快、适应性强、恢复效果好。研究成果为我国智能电网的发展提供了一定的参考。

For the access of the micro-grid in the distribution network,more safety factors need to be considered for fault recovery,the current fault recovery method has problems such as large amount of calculation and long fault recovery time.Taking the minimum network loss,the minimum number of switching actions and the minimum power loss as the objective function,a fault recovery model of distribution network with micro-grid is established,and the improved binary particle swarm algorithm and genetic algorithm are combined to solve the model.The analysis of various failure recovery situations verifies the feasibility of the fault recovery method.The results show that,compared with the traditional recovery method,the proposed method has fast convergence speed,strong adaptability and good recovery effect.This research provides a certain reference for the development of smart grid in China.
