Impact of Wind Electric Generator on Power Quality

Abstract

The use of renewable energy sources (RES) for electricity generation is increasing to reduce the dependence on fossil fuels. The trend is to connect renewable energy sources, such as wind energy, with grid to meet the increasing power demand. Also, power quality (PQ) is gaining importance in recent past due to the increase in sensitive loads, application of non linear loads and switching devices and increasing awareness of implication of poor power quality. With a view to these issues this paper presents a review of PQ problems associated with the wind electric generation. Wind farms are not only affected by poor power quality, but also affect the quality of power. Based on both the aspects various PQ issues are discussed in detail.
