Enhancement of Voltage Stability in Grid Connected Wind Farms Using SVC

By K. Sree Latha and Dr. M. Vijaya Kumar


Abstract-- The wind energy stands out to be one of the most promising new sources of electrical power in the near term. The latest technological advancements in wind energy conversion and an increased support from governmental and private institutions have led to increased wind power generation in recent years. Wind power is the fastest growing renewable source of electrical energy hence it has become necessary to address problems associated with maintaining a stable electric power system. Unlike conventional sources, wind does not provide reactive power, which is necessary to maintain acceptable voltage conditions on the network. The use of Flexible AC Transmission Systems (FACTS) in distribution network to compensate for vagaries such as production related to wind energies and to control the voltage is an optimal solution. In this paper the effect of real power supplied, reactive power consumed due to variation and fluctuation of load and wind speed studied, the effect on grid voltage due to variation is extensively considered. The variation in voltage of grid is controlled by SVC which is shunt connected Thyristor control Reactor and Thyristor switched capacitor TCR-TSC. Results are produced in MATLAB/SIMULINK and considerable improvement in grid voltage received by compensating the reactive power
