Abstract

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.

Abstract

Objectives: This paper deals with the power system problems like sag, swell and also improve power quality of the three phase system. Methods: Previously many compensating devices were used to improve the power quality of the system. Here the detailed analysis of matrix converter can be used to improve the power quality in the three phase system. Findings: The matrix converter is introduced as the compensating device. The major advantage of matrix converter is the elimination of dc link capacitor. These DC-link Capacitors results in an inefficient compensation of the system. By implementing the new strategy of using matrix converter as IUPQC the power quality is improved efficiently than the conventional methods. Applications: This system is designed for the power quality improvement in the three phase system.
