A Review on Dynamic Voltage Restorer in power systems concerned to the issues of Power Quality

Abstract

Abstract Power Quality issues are the important concepts for all types of electricity usage consumers due to increase in power demand at different levels. For achieving power demanded, the power grid is incorporated with single or integrated renewable energy sources which resembles in rise of additional power quality issues than in regular isolated system. In this, a detailed review on different nature of power quality issues, monitoring devices of power quality & power quality mitigation especially by the dynamic voltage restorer-DVR has been explained. A review on DVR for power quality issues like voltage swell, sag, flickers, imbalance, reactive power imbalance and harmonics with distinct power circuit structure and the detailed control strategies for mitigating the mentioned issues is presented in this paper.
