Abstract

This paper is concerned with the optimal placement of protection devices in a microgrid using particle swarm
optimization algorithm. One of the main advantages of
Distributed Generation (DG) scheme and microgrids in modern
distribution systems is the reduction of number of outages and the associated damages caused by them. This task is
accomplished by supplying a feeder from multiple sources. In
order to prevent generator instability in DGs connected to utility, it is necessary to improve the protective schemes of traditional distribution systems and also to use proper relaying and setting for DGs. All of the downstream overcurrent (OC) relays of each DG are coordinated together and also should be coordinated with OC relay that is installed on the Point of Common Coupling (PCC) which is set at Critical Clearing Time (CCT) as a definite time, to have a desirable performance on each outage. In this paper, by the use of graph theory, various branches of a feeder
are identified and the constraints for using particle swarm
optimization algorithm to optimize the location of protective equipment are derived. In the proposed algorithm, the location, type and direction of relays are optimized simultaneously.
