Evaluation and sizing of energy storage systems for microgrids

This paper evaluates the energy storage systems (ESS) in the microgrids. The ESS unit is regarded as an added energy resource in microgrid system to support the power balance when regular distributed energy resources (DERs) are incapable of matching the load demand. Sizing and specifications of ESS are investigated in this paper using several test case scenarios. An overall evaluation of the energy storage functionality is carried out for the microgrid by looking at different storage options for diverse operating scenarios.
