Abstract :
Distributed power generation will be formed in many weak distribution networks, after renewable energy sources are connected to them. It is very important to increase the reliability and efficiency of using these renewable energy sources. By using DVR (dynamic voltage restorer), the power quality problem in distributed power generation (e.g. voltage fluctuation) can effectively be solved. In this paper, super capacitor based energy storage will be used as the peak power unit, to ensure the power quality on the both sides of the DVR during short time and on the one side of the DVR during long time duration. The proposed control methods of each inverter and converter have been verified in Matlab simulation and tested in our laboratory. High power quality can be achieved in distributed power generation with the presented systems
