Optimal sizing and placement of DFIG Wind Farm for Line Loss Reduction and Volt/Var Control in Distribution Network
Résumé
Over the past three decades, the amount of small scale wind farms (WF) used as distributed generators (DG) source within the distribution system has rapidly increased. From the benefits of power electronics, the doubly fed induction generator (DFIG) based variable speed wind turbine is the most used. The most important advantage of DFIG is the continuous supply of active and reactive power, which can be used for voltage profile improvement in distribution networks (DN). This paper presents a solution for Line Loss Reduction, voltage and reactive power control in the distribution network, by the use of Particle Swarm Optimization (PSO) technique to find DFIG WF optimal active (P) and reactive (Q) power output for losses reduction and voltage profiles improvement in distribution system (DS). In conclusion, the suggested approach is utilized on both the 34-node and 69- node IEEE DS, to evaluate the algorithm. Simulation results show that the technique can improve dramatically the voltage profiles of DNs.
