This paper accord the Power Quality interpretation to make apparent for electricity consumers been made better power quality with application of DVR.Despite of advantages of DVR, it focuses full extent of the relatedness surrounded by loads, various power networks. DVR is most accepted power device which could be used for better solution for the disturbances of voltages in distribution systems for sensitive loads. For efficiency considerations, the DVR mostly hinge on an act of presenting the control modus, and can be harnessed to switching the inverters. Reliability of hysteresis voltage control with ease in operation under variable switching frequency can be trustworthy for a DVR can introduced and the proposed methods achieves good compensation of voltages under disturbances and can be seen by the simulation by using fuzzy logic controller.

Control Methodology

The intermittent nature of photovoltaic (PV) generation causes the voltage to fluctuate and may lead to instability, especially, in case of high penetration. In this paper, a methodology is proposed to control the reactive power generation of PV-inverters. The objective is to mitigate the voltage fluctuations at the point of common coupling (PCC) resulted from increasing or decreasing the active power output of PV plants which is dependent on solar radiation level. The generic PV-inverter models developed and recommended by the Renewable Energy Modeling Task Force (REMTF) of the Western Electricity Coordinating Council (WECC) is used to analyze the effect of high PV penetration on the dynamic voltage stability of distribution networks. Then, the tested distribution network with the embedded PV plants is modeled and simulated using PSS/E software. Levels of control that are built-in PV-inverters are tested in the case of normal operation and during disturbances. Comparison results show that the most suitable control methodology in case of disturbances and after fault clearance is the local voltage control. While the plant voltage control with coordinated V/Q control is the most preferable control methodology during normal operation.
