Abstract
Wind generation is currently the leading form of new renewable generation in the world. 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. Wind power has significant variation over shorter time periods, but is growing very consistent from year to year. A significant amount of wind power is integrated into the power system day by day. With large variations in wind generation, reactive power flows on transmission lines and voltage are two major variables which affect the performance of the power system. The shunt connected FACT devices such as a static var compensator (SVC), which is dynamic reactive power compensator whose reactive power output depends upon the system voltage, is adopted for control of bus voltage magnitude and to bring the system near to unity power factor, thus for mitigation of reactive power. This paper presents the reactive power control by application of SVC in the power system having high wind power generation and its effect analyzed on static and dynamic var mitigation with the change of the location of SVC to far off the bus. For analysis Rajasthan Grid(India), comprising of different voltage level with high wind power penetration in the Western part selected. Mi.-Power software is used in actual field conditions simulation and analysis. The comparative effect of altering the location of SVC analyzed.
