Optimal allocation of multi-type FACTS devices and its effect in enhancing system security using BBO, WIPSO & PSO

Abstract FACTS devices play a vital role in improving the static as well as dynamic performance of the power systems. However the type, location and rating of the FACTS devices play a major role in deciding the extent to which the objective of improving the system performance is achieved in a cost effective manner. In this work an objective function comprising of cost, line loadings and load voltage deviations is proposed to tap maximum benefits out of their installation and the weights assigned to them decide their relative importance. The impact of installing TCSC, SVC, TCSC-SVC and UPFC in minimizing the formulated objective has been analyzed in enhancing security, under increased system loading conditions.
