Abstract

One of the essential strategies for restricting fault areas and reducing the number of affected customers in each outage is the simultaneous use of distribution automation systems and distribution generations (DGs). The use of DGs in the distribution networks affects the problem of remote control switch (RCS) placement. This study presents a new and practical method to determine the optimal location of RCSs in the presence of DGs. In this research, an approach for the minimization of energy not supplied, the costs of installation, maintenance and operation of equipment, taking into account the practical parameters of the network have been presented. Also, the structure and possible constraints of the real network, according to opinion of experts, are included. The practical parameters have been extracted by the geographic information system and software of recording event (ENOX). The effects of DG units on the optimal number and location of switches have been assessed. To optimize the problem, a combination of genetics and particle swarm optimization algorithms has been utilized. The efficiency of the proposed method is shown by simulation results on standard 33-bus and real medium-voltage networks.
