In a microgrid with solar and storage, storage dispatch primarily serves to:

Storage dispatch controls when to charge or discharge the storage assets to support the microgrid’s operation. By actively managing the inverter-based storage, you can damp voltage fluctuations that come from changing solar output, helping keep voltages within safe limits. When loads or solar generation create a high-demand moment, discharging storage during that peak smooths the total demand, reducing peak power and associated costs. Storage can also respond quickly to frequency deviations, injecting or absorbing real power to help restore the target frequency, which is especially important in islanded operation where inertia is limited. Because these capabilities can be leveraged together with coordinated control, storage dispatch serves voltage stabilization, peak shaving, and frequency regulation all at once.
