Remote communities are typically isolated from large power systems (off-grid) and use diesel generation in conjunction with a dump load to feed the local grid. Inherent high operation costs and emissions can be reduced with the integration of renewable energy (RE) sources at a high penetration level. These renewable sources such as wind and solar (PV) energies have been proposed due to their economical and environmental advantages.planning and operation of power systems with medium to high penetration levels of RE implies some difficulties due to the stochastic and intermittent characteristics of the sources. Furthermore, isolated grids with fossil-fuel based power generation that have been integrated with RE (primarily wind farms) require the additional use of dump loads or generation curtailment.The implementation of energy storage systems (ESS) with large storage capacity for several hours, offers a good solution for avoiding the energy wasted from intermittent sources and increases the penetration of RE
