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.
Another use case for battery storage on microgrids is aggregating BESS as a virtual power plant (VPP) to correct imbalances in the utility grid. At the grid level, when the supply of power from renewables temporarily drops, utilities need to respond quickly to maintain equilibrium between supply and demand and stabilize the grid frequency.
Each string has 60 elements. The entire system has a rated capacity of 300 kWh/120VDC (2,500 Ah). The maximum Depth of Discharge (DoD) allowed is 40%. In the Ilha Grande microgrid, the energy storage system was designed to have 24-hours of autonomy and to meet a demand of approximately 130 kWh/day including power inverter losses.
Because the optimum depth of discharge is 100 %, it can be seen that in most cycles the battery delivers all the energy to the microgrid. For each cycle, the resulting degradation is equal to cycle degradation for 100 % depth of discharge, so in each cycle the battery gives as much energy as possible.
... The integration of battery energy storage systems with photovoltaic systems to form renewable microgrids has become more practical and reliable, but designing these systems involves complexity and relies on connection standards and operational requirements for reliable and safe grid-connected operations.
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.
