FACTS devices are used in power systems to increase the loadability of the system or to optimize other objective, like to reduce the power loss in the system. When only a single objective is considered in the introduction of the FACTS device, other end results of the system are adversely affected leading to increase in the total cost of the system. This paper proposes a method for considering multiple objectives and to arrive at a solution optimal for all considered objectives. The method proposed in this paper uses application of Differential Evolution (DE) algorithm in Weighted Additive Fuzzy Goal Programming (WAFGP) method. Use of STATCOM in Indian utility Neyveli Thermal Power Station (NTPS) 23 bus system is used for testing and validating the proposed method.
