A Behind-the-Meter Battery Control Algorithm with the Consideration of Li-ion Battery Degradation

A behind-the-meter energy storage system can be utilized to mitigate the impact of renewable generation and to improve the monetary benefit to the owner. However, different charging/discharging profiles will directly impact the cycle life of a battery system. A new battery scheduling algorithm with consideration of battery life degradation has been proposed. Software simulations have been performed on a modified IEEE 13-node test feeder with a 100 kW / 400 kWh battery system to validate the voltage regulation and demand charge reduction functionalities. Hardware experiments have been performed to analyze the effectiveness of the proposed algorithm on battery life management.
