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.
Because of the fundamental uncertainties inherent in microgrid design and operation, researchers have created battery and microgrid models of varying levels of complexity, depending upon the purpose for which the model will be used.
For example, if a battery is replaced when it falls to 80% of original capacity and microgrid operation requires a certain battery capacity, the battery must initially be oversized by 25% to maintain the desired capacity at the end of the battery’s life.
Lithium-ion (Li-ion) batteries are the most highly developed option in size, performance, and cost. A broad ecosystem of manufacturers, system integrators, and complete system providers supports Li-ion technology. However, the vendors best equipped to bring value to microgrids bring the right components to each project.
