According to the existing literature,,,, typical simple microgrids (one type of energy source) connected to the main grid have a rated power capacity in the range of 0. 05–2 MW, a corporative microgrid is in the range between 0.
A novel formulation for the battery energy storage (BES) sizing of a microgrid considering the BES service life and capacity degradation is proposed. The BES service life is decomposed to cycle life and float life. The optimal BES depth of discharge considering the cycle life and performance of the BES is determined.
By adding battery energy storage (BES) to a microgrid and proper battery charge and discharge management, the microgrid operating costs can be significantly reduced. But energy storage costs are added to the microgrid costs, and energy storage size must be determined in a way that minimizes the total operating costs and energy storage costs.
The use of battery is not limited to microgrid and the economic approach is not the only approach for determining the optimal energy storage size. In,, energy storage size is determined based on frequency maintenance in a microgrid disconnected from the grid, and economic issues are not considered in these studies.
