Computation of maximum loadabilityof power systems including wind farms using particle swarm optimization

Recently, the integration of wind farms has increased to high penetration levels. Mathematical modeling of wind generator is concerned in this paper. To discuss the steady state condition of power systems with wind farms, the stall regulated fixed speed wind generator (SR-FSWG) power flow model is considered. The load flow equations are solved using Particle Swarm Optimization technique including SR-FSWG. The OPF is formulated as a Multi Objective Problem (MOP). The first function is to determine Maximum loadability. While, the second one is cost of generation and the third is voltage deviation at the load buses. We employ IEEE-14 bus system to verify the proposed technique. The result shows that the proposed method satisfies all the three objective function.
