Optimal Reactive Power Flow In The Presence of Wind Power For Active Power Loss Minimization

This study proposes a solution to the optimal reactive power flow (ORPF) in power systems incorporating wind power. Two aspects are studied in this paper. The first one is the technical aspect, includes the real power loss reduction, which presents the main objective of this work. The second is the economic aspect, considers the optimal wind power and FACTS devices investment cost. The autonomous group particle swarm optimization (AGPSO) optimization technique is employed and compared with improved and modified particle swarm optimization (IPSO & MPSO) for solving the proposed ORPF problem. The Algerian power system 59-bus systems are used as test systems. The simulation results obtained from the proposed algorithm shows that this algorithm is capable to give higher quality solutions to solve the optimal reactive power flow problem.
