摘要
提出一种基于加权理想点法的配网故障供电恢复策略。首先以网损、电压质量、负荷均衡作为重构目标,确定综合评价函数,并利用粗糙集理论确定各子目标函数的权系数,然后基于理想点法获取综合评价函数的最优解。验证结果表明,所提策略更符合实际配网供电恢复的要求,同时克服了传统权重设置依靠先前经验带来的不确定性问题,计算速度快。
A strategy of power restoration from distribution network fault based on weighted ideal point method is proposed,which takes the power loss,voltage quality and load balance as the goal of reconfiguration to establish the comprehensive evaluation function,adopts the rough set theory to determine the weight coefficient of each sub-objective function,and then applies the ideal point method to obtain the optimal solution of the comprehensive evaluation function. The results of verification show that,with faster calculation speed,it avoids the uncertainty of weight setting depending on previous experience,more corresponding with the power restoration requirement of actual distribution network.
