Optimal Location And Size of The STATCOM to Enhance The Power System Stability

Abstract

The importance of power system operation is becoming increasingly significant due to the escalating demand observed in many nations. The exponential growth in load demand exerts substantial stress on electrical power systems, since they run in close proximity to their critical thresholds due to limitations imposed by environmental and economic factors. The basic goal of operating electrical power networks is to efficiently supply energy to users at optimal frequency and voltage levels, with a focus on cost minimization.

 The main objective of this study is to examine the augmentation of voltage stability margin by deploying Flexible AC Transmission Systems (FACTS) at their ideal positions.  In order to determine the most efficient size of a Static Synchronous Compensator (STATCOM), it is necessary to explore the relationship between the loading factor and the capacity of the STATCOM. The case study utilized the Iraqi National Super Grid System (INSGS), which consisted of a 24-bus configuration.

The effectiveness of the CPF technique has been assessed in the framework of the Iraqi Super Grid test System. The appropriate place for attaching STATCOM to enhance voltage stability in the Iraqi network system was identified to be Bus (20).
