OPTIMAL LOCATION OF FACTS DEVICES FOR REACTIVE POWER PLANNING USING GENETIC ALGORITHM

Abstract

The demand for electric power is ever increasing due to rapid industrialization and population growth. Perhaps in India, the of total power generation requirement has been tremendously increased during the past decades. And hence power systems became more complex and have grown very large. It is now important to design and operate systems with high degree of practical efficiency, security and reliability. In recent years, the main emphasis of power system engineers has been on the improvement of service quality. It is noted that increase in capacity of interconnection systems, allow a reduction in the capacity of generation, means a more economic management of the system. This increase, especially in the case of long distances can be obtained more economically by the use of more complex technological devices. The resulting reliability of the electric system and the consequences on system operation are the subject in-depth study; these phenomena are sometimes difficult to represent at the planning stage and then concern more particularly the implicit or explicit margins required by the operators and the performance of the control system at his disposal. In other words, the reactive power control is aimed at the realization of the so-called rational system operation. Further, reactive power optimization has gained more importance due to exploitation of power generating sources at remote places and inclusion of long EHVAC as well as long DC transmission networks in the system
