The Stability Solution for 100% Variable Renewable Energy Supply in Microgrid Through Batteries Energy Storage System : Case Study The Iconic Island Nusa Penida

Since Nusa Penida Island has a complete resource of intermittent and non-dispatchable energy resources such as wind and solar energy then maximum integration of such power plant is possible to develop. However, the stability of the grid will be a consideration of the grid operator. Based on the research that discusses grid issue when supply by one hundred percent of RERs, its only possible and allowable if the advanced grid controller or defense backup system is applied to the grid. BESS are pretty suited to support operation of distribution system, to facing the challenges created by distributed, fluctuating, and uncertain renewable energy. The main contribution of this paper is to demonstrate (based on simulation) effect of BESS to the grid as a backup system. However, the advanced grid controller may better solutions.
