Comparison and Analysis on the Role of D-STATCOM and DVR with PI Controller to Improve the Power Quality in Distributed Networks

In the running years and the coming era, power quality is one of major concerns in the expansion of power electronics. Whenever using a non-standard voltage, current or frequency that results a failure or disoperation of end user equipments. Distribution networks, industrial loads etc., are suffered by power quality problems. A number of power quality solutions are provided by custom power electronic devices. Now, a wide range of flexible controllers, which capitalize on newly available power electronic components are utilizing for power application among them, the Distribution STATic synchronous COMpensator (DSTATCOM) and Dynamic Voltage Restorer (DVR) or makes the efficient solutions for Improving power quality in distribution networks.
