Abstract

Abstract : Sustainable microgrid primarily powered by renewable energy sources is a recent concept to fulfill the pledge of delivering reliable power supply for upcoming power systems. This study presents a microgrid system primarily powered by wind and solar energy sources and identifies the issues related to the design, operation, and control of the system. The system is designed and simulated to detect the practical issues involved in the control and operation of the sustainable microgrid system based on wind and solar sources. The technical challenges and a brief plan of conceptual methods to detect some of the technical issues are presented for further analysis. To achieve power quality improvement, effective control architecture is described here. Furthermore, an advanced random pulse position modulation technique for the voltage source inverter is proposed to influence the DC‐link inductor which further reduces the harmonic distortion. A current injected control loop (CICL) is also proposed to improve the dynamic behavior of microgrid, due to change in solar radiation and wind speed, which causes DC bus voltage oscillation and, hence, affects in proper system operation. The simulation results report that the microgrid system powered by renewable energy sources have a good performance.
