Wind Power: Voltage and Power Quality Control System

Abstract

Power quality is a critical issue in a power system. The nonlinear nature of loads causes the majority of the pollution problems in the power system. Wind power, in general, does not contribute to voltage regulation in grids due to the large amount of non-linear equipment, impact, and fluctuating loads. Wind power is also frequently a source of voltage sag or swell. Power systems are frequently regarded as insufficient because they have a low short-circuit ratio when compared to a grid. As a result, network voltage control becomes a difficult task. The loads are also vulnerable to short-duration disturbances such as voltage sags or swells. The power systems are often considered feeble in that they possess relatively low short-circuit ratio, compared to a grid. Network voltage control becomes a challenging task as a result.
