The main theme of this paper presents an improved control method for unified power quality compensator (UPQC) with an unbalanced load. In today's power systems power quality plays a crucial role. Power quality used to attain better stability to system. If the power quality is improved then the system produces better performance. Microgrid is one among the widely used areas to reduce the loses. Microgrid is a small scale version of utility grid which can operate independently (Standalone mode) as well as in conjunction with main grid. Microgrid involves use of renewable energy sources like solar, wind, fuel etc. This paper involves reduction of load harmonics in standalone microgrid designed with solar and wind with UPQC using Epll and alpha-beta theory
