رویکرد بر مبنای حساسیت جدید برای تخصیص بهینه خازن های موازی در شبکه های توزیع با استفاده از PSO

This paper proposes a new methodology for optimal allocation of shunt capacitors in distribution systems. The proposed method combines various objectives and constraints into a Comprehensive Constraint Multi-objective Function. The function has been optimized using a Particle Swarm Optimization (PSO) based method. Attempts have also been made to improve the performance of PSO. The search space of PSO is reduced by introducing a new reactive power flow sensitivity approach that determines the set of candidate nodes suitable for capacitor placement and also by employing a new constrained particle structure. The proposed method is tested on a 69-bus test distribution system and the application results are promising.
