Impact of thyristor controlled series capacitor on power system reliability

Abstract

This paper examines the impact of a thyristor controlled series capacitor (TCSC) on power system reliability. In this application, the TCSC is employed to adjust the natural power sharing of two different parallel transmission lines and, therefore, enable the maximum transmission capacity to be utilized. The improvement is measured using the two reliability risk indices of loss of load expectation (LOLE) and loss of energy expectation (LOEE).
