摘      要：In distribution systems,network reconfiguration and capacitor placement are commonly used to diminish power losses and keep voltage profiles within acceptable ***,the problem of DG allocation and sizing is great *** this work,a combination of a fuzzy multi-objective approach and bacterial foraging optimization(BFO) as a meta-heuristic algorithm is used to solve the simultaneous reconfiguration and optimal sizing of DGs and shunt capacitors in a distribution *** objective is transferred into fuzzy domain using its membership ***,the overall fuzzy satisfaction function is formed and considered a fitness function inasmuch as the value of this function has to be maximized to gain the optimal *** numerical results show that the presented algorithm improves the performance much more than other meta-heuristic *** results found that simultaneous reconfiguration with DG and shunt capacitors allocation(case 5) has 77.41%,42.15%,and 56.14%improvements in power loss reduction,load balancing,and voltage profile indices,respectively in 33-bus test *** result found 87.27%,35.82%,and 54.34%improvements of mentioned indices respectively for 69-bus system.
