Parenthetically, capacitor allocation as well as sizing may be the only convenient solution for RPC of power systems. Loss sensitivity factor (LSF) is applied here for finding optimum capacitor position. This paper presents quasi-oppositional fast convergence evolutionary programming (QOFCEP), fast convergence evolutionary programming (FCEP) and evolutionary programming (EP) for optimum location and sizing of shunt capacitors in isolated microgrid (MG) for minimizing total real power loss throughout the day with and without demand response program (DRP). 33-node, 69-node and 118-node isolated MGs has been studied to authenticate the efficacy of the suggested approach. Each MG includes small hydro power plants (SHPPs), solar PV plants (SPVPs), wind turbine generators (WTGs), diesel generators (DGs) and plug-in electric vehicles (PEVs).
