Optimal Power Flow of the Manokwari Power Grid Regarding Penetration of 20 MW Combined Cycle Power Plant

Optimal power flow (OPF) is used to calculate the optimal power in to a power grid under some constraints. As a heuristic optimization method, particle swarm optimization (PSO) has been used to obtain optimal solution of penetration of 20 MW Combined Cycle Power Plant (CCPP) of PT. SDIC into 36 bus of Manokwari power grid owned by PT. PLN P2B. Results of simulation show that power loss is about 6.9749 MW by occupying the CCPP power plant at maximum of 20 MW while the minimum cost is reached in generation of 4.6298 MW of the CCPP generator when the other generators of micro-hydro and diesel power plants are work at maximum operation.
