Optimal Location of SVC Considering Techno-Economic and Environmental Aspect

Abstract

Maintaining Line stability, improving voltage profile, minimizing real power loss and reducing emission are one of the most vital issues in the operation of electrical power system. Flexible AC Transmission System devices (FACTS) like Static Var Compensator (SVC) can enhance line stability, improve voltage profile and minimize both the power losses and emission. Thus, the allocation of FACTS devices in power system is of great importance. However, due to their high installation cost involved, it is important to place these devices optimally in a power system. In this paper, an iterative study is carried out in Mi-power software for IEEE 57 bus test system. The severity of the line has been detected using Fast Voltage Stability Index (FVSI) and thereafter SVC is placed on the identified critical buses separately to save computation time and search space. In addition to the technical aspect, other aspects i.e. economic and environmental issues are also considered in this paper while placing SVC at the optimal location.
