Email this article Pv Based Interline Dynamic Voltage Restoring Device For Mitigation Of Power Quality Problems
Abstract
Now a days the renewable energy sources importance has increased in the distribution system. In this paper an interline dynamic voltage restorer (IDVR) has proposed for the distribution systems to mitigate voltage sag/swell problems and improve power quality. In general for the normal voltage levels, the DVRs should be bypassed. Instead of bypassing the DVRs, this paper proposes new operating scheme for the DVRs, if needed, to improve the displacement factor (DF) in any one of the involved feeders. Generally an interline dynamic voltage restorer consists of several dynamic voltage restorers (DVRs) with a sharing dc link. IDVR is connected to the independent feeders to secure the electric power to the critical loads. One of the DVRs compensates for the local voltage sag in its feeder, and the other DVRs replenish the common dc-link voltage is supplied by using solar energy (PV). DF improvement can be achieved via active and reactive power exchange (PQ sharing) between different feeders. To validate the proposed system, Simulation results have been presented using MATLAB/SIMULINK software.
