Optimal placement of STATCOM for improving voltage profile and reducing losses using crow search algorithm

Abstract

Continuous expansion of power demands and lack of supply have led the study on Flexible Alternating Current Transmission System (FACTS) devices, a fascinated area for research. Considering the benefits and applications of FACTS devices, it aims to investigate the optimal placement of Static Synchronous Compensators (STATCOMs) to enhance voltage stability limits and to reduce the transmission losses. An objective function is modeled to minimize the total line losses in the power system by placing STATCOM. Using this objective function, the best location for placement of STATCOM is achieved by using Crow Search Algorithm (CSA) optimization technique. IEEE 14, IEEE 30 and IEEE 57 standard bus systems are used to vaUdate the proposed method.
