Integration of wind energy system in microgrid considering static and dynamic issues

Microgrid is an integrated structure of distributed energy resources (DERs) which are connected together to deliver electrical power to a group of consumers under standalone mode and can also exchange power with the existing utility grid under grid connected mode. Integrated DERs in microgrid is getting importance over the last few years. As the integration of renewable based generation specially wind energy system has significant influence on various static and dynamic features of power system, wide scale penetration of wind turbines in microgrid system deserves a detailed investigation. This paper has investigated one of the major static issues - grid loss for the placement of wind turbine in a microgrid system. The level of penetration has finally been determined by examining the grid rule compatibility of post-fault voltage recovery feature of wind integrated system. Results show that maximum 30% wind energy penetration in test microgrid can ensure satisfactory static and dynamic operation.
