Operating Strategies Optimization of STATCOM for Improvement of Voltage Profile

Abstract

The old power grid was not designed to meet the increased future demands of a restructured electricity market place, the digital society energy requirements, or the increase in the usage and variability of renewable power generation. As a result, the electric grid needs to be upgraded to a high-performance system that will have the full capability to serves today’s need and future power demand. In the modern power system, the stability of voltage is one important consideration. During the heavily loaded condition, the voltage stability problem becomes further critical. In this paper a shunt compensator, Static Synchronous Compensator (STATCOM) has been connected in the system and significant improvement in voltage profile has been obtained. By identifying the optimal location with the highest voltage stability in the network, it is possible to have a network with a healthy voltage profile resulting in an increase in voltage security.
