Optimization of Fault Current Limiter for Restoring Recloser-Fuse Coordination in Distribution System Integrated with Synchronous DG Units by Using MOPSO Algorithm
Authors: Purushottam Khadka, Asha Khanal
Abstract—With the integration of synchronous DG units in the distribution system, the contribution of fault current by the DG units to the fault location increases. The problem with the fault current provided by DG unit is that the proper coordination between protective devices such as recloser-fuse coordination is disturbed. With the optimal planning of Fault Current Limiter (FCL), the protection-coordination between recloser-fuse can not only be maintained but also the cost associated with FCL installation can be reduced. Thus, in this paper, the two objective functions: 1) the reduction of the fault current through the protective device and 2) the reduction of cost of FCL installation are considered. The optimization problem is solved by using Multiple Objective Particle Swarm Optimization Method (MOPSO) and the optimization result for Canadian Bench Mark Test System shows that the recloser-fuse coordination is restored in synchronous DG integrated distribution system. The solution is validated in ETAP software.
