Effect of new deregulation policy on power quality monitoring and mitigation techniques

With the dawn of the competitive environment, electric power system restructuring is becoming a great concern for both electric utilities and customers. In this paper, the effect of power system deregulation on the power quality problems is investigated. Identifying the high priority research areas related to electric power quality in deregulated power systems and investigating the advances made in this area over the last decade constitutes the main goal of this paper. The paper addresses the definition of deregulated environment, and the different mitigation techniques implemented to improve the system power quality. Moreover, the advances in research on using modem signal processing techniques like a wavelet transform in developing automated recognition of power system disturbances is pointed out.
