Comparative Analysis of PSO and Proposed Hybrid (CSA-SSA) Algorithm for Optimal DG Location and FCL Sizing
Power system is the complex network in nature due to the integration of several devices such as circuit breakers, fuses, relays and power electronic equipment’s. Protection of these devices is a highly exacting task in the modern power system. The incorporation of DG has many advantages besides this it causes grid disturbances. DG integration with the existing distribution system increases the short circuit current levels. DG is producing fault currents which exceeds the breaking capacity of C.B and fuses. Fault current limiter (FCL) is most adapted technique to limit the abnormal electric current levels to an acceptable level. In this paper, Controlled Impedance type of FCL (CI-FCL) is used and it is tested on IEEE standard 33 and 69 distribution bus systems. The obtained Hybrid (CSA-SSA) results are verified with PSO technique.
