A case study of Western Rajasthan wind energy effects in power system and remedies

Abstract

Wind generation is currently the leading form of new renewable generation. The power generation through wind energy totally dependent on the flow of the wind due to uncertainty and randomness of wind flow, the generation of power is quite fluctuating in nature and large-scale wind farms may cause significant impact to the stability and power system safety. This paper presents a case study of Western Rajasthan which become high wind power penetration zone. Which includes the requirements of the reactive power mitigating device, the analysis of voltage, active and reactive power flow under condition of sudden increase of wind power and effect of reactive power compensating device Static Var Compensator if it is placed at major GSS of Western Rajasthan. To analyze the situation Mi-Power software is used. It is concluded that for Rajasthan power system the installation of suitable capacity SVC is must, preferably at the main wind bus.
