Frequency Control ‐ P(f)
Frequency is held to a very strict tolerance, therefore, deltas in frequency must be mitigated. Renewable energy can introduce fluctuations in grid frequency. Energy storage, specifically battery storage, is an ideal way to solve this issue due to its nearly instantaneous reaction time to frequency events. Enhanced inverter controls and rapid response times make for a great combination.
Voltage Control ‐ Q(V)
Fluctuations in grid voltage, especially at the far ends of distribution feeders, can cause damage to loads and utility equipment. Battery inverters can provide full, four-quadrant support to help maintain voltage levels at points of interconnection by utilizing the volt-var function or a voltage droop.
