کنترل هماهنگ بهینه سازی توان راکتیو در سیستم قدرت توزیع با انرژی توزیع شده باد؟

Distributed generation (DG) systems are considered an integral part in future distribution power system. The reactive power injections from DG units, are seen as a cost-effective solution for distribution system voltage support, energy saving, and reliability improvement. This paper proposes a coordinating control method of reactive power optimization in distribution power system with distributed wind energy. The reactive capability limits of doubly fed induction generator (DFIG) are included in the optimization model. The problem of reactive power output/absorb of adjustable compensating capacitor and wind turbine (WT) is formulated as constrained conditions; differential evolution algorithm (DE) integrating depth-first search is developed to effectively obtain optimal solutions. The proposed algorithm is applied to a practical test system and results are compared and presented.
