Optimal allocation of Wind Turbines in distribution systems based on social welfare evaluation

In this paper, a hybrid optimization method that combines Particle Swarm Optimization (PSO) and Optimal Power Flow (OPF) is proposed in order to allocate Wind Turbines (WTs) in distribution systems. The OPF is used to determine the optimal number of WTs in order to maximize the Social Welfare (SW) of the network while the PSO is used to choose the best type of WTs at each candidate bus. The OPF problem is solved using Step-Controlled Primal Dual Interior Point Method (SCPDIPM) considering network constraints. The effectiveness of the proposed method is verified on an 83-bus 11.4 kV radial distribution system.
