The smart charging and discharging of ESSs are both crucial for saving energy, achieving optimum ESS efficiency, increasing ESS lifetime and achieving cost-effective network operation. Further research on the application of smart charging and discharging algorithms for optimal ESS implementation is recommended.
Several important parameters describe the behaviors of battery energy storage systems. Capacity [Ah]: The amount of electric charge the system can deliver to the connected load while maintaining acceptable voltage.
By using these concepts, intelligent charging and discharging protocols are developed in that framework to save ESS energy and lifetime. However, this framework is only developed for micro-grids by considering the distance to a placed ESS as a controlling factor and not extended to distribution grids.
Two conditions need to be satisfied in order to initialize the charging or discharging mode. If the input current is positive, and the state of charge of the battery is larger than the minimum state of charge (minimum SOC represents the discharged state), the discharging mode will be activated.
The EV charging impacts to distribution networks should also be incorporated during system modelling and objective function formulation. Moreover, various ESS control approaches (e.g., MAS) can be employed to facilitate optimal ESS operation in distribution networks.
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
