A Flexible Wind Energy Scheme for Voltage Compensation and Flicker Mitigation

Abstract

The wind energy is used widely in the modern electrical systems. This paper proposes a novel functionality of the interface, between the self excited induction generator (SEIG) coupled with a wind turbine and the utility network, not only to control the active power flow, but also to mitigate the voltage flicker and regulate the voltage at the Point of Common Coupling (PCC). In order to achieve this and to ensure constant dc supply for the STATCOM, the generated voltage of the SEIG is rectified and the de-side voltage is controlled using a de-chopper. The SEIG will be modeled under the EMTDC environment using the FORTRAN compiler. Simulations of the suggested scheme are conducted to evaluate the performance of the novel system.
