Optimal Reactive Power Planning And Real Power Loss Minimization Using Cuckoo Search Algorithm

Abstract: Reactive Power planning for the meeting the future demand is necessary for ensuring voltage stability of power systems. New reactive power sources may be installed or VAr output from existing sources may be optimized in reactive power planning. In this work, a new reactive power planning scheme is suggested by optimizing the real power loss and reactive power generation from SVCs in a system. Real power loss minimization results in optimized reactive power flow in the system. This work aims for reactive power planning by optimal reactive power flow and reactive power generation. For optimizing the reactive power, a new nature inspired cuckoo search algorithm (CS) is exploited. The proposed algorithm has less number of parameters and has good convergence quality. The suggested method is tested on the standard IEEE-30 bus system and the results are quite encouraging
