Configuration
PCS - Energy storage has 2 main parts. The PCS (Power Conversion System) handles AC to DC and DC to AC conversions, with AC to DC used for charging the batteries and DC to AC which converts battery storage power to AC Power and fed to the grid or Load.
BMS - The Battery Management System (BMS) controls proper operation of each cell ensuring the system works within the safe range of voltage, current and temperature, does the battery cell charging, balancing, and health monitoring. This ensures higher efficiency and longer life of the battery cell.
Battery – Lithium Ion batteries are used in the ESS. Using combination of series and parallel cells to form battery clusters, and further arranging the clusters in series to form battery modules.
Energy Management System - The purpose of the EMS is to monitor the power flow according to the specific application.
Transformer - According to the system size, medium / low voltage or high voltage/medium voltage in substations

Advantages of ESS
Uninterruptible Power Supply : ESS can provide power during Power interruption.
Load Levelling : Due to charging demand during the day time, the grid is subjected to a lot of stress, the ESS helps flatten the demand curve by charging when electrical demand is low and discharging when the demand is high.
Peak Shaving : Drawing power from the batteries during higher cost day time hours and recharging during Lower cost right time.
Using Renewables to Supplement Power : Supplementing the energy generated by Solar panels when sun energy is available, or wind turbine when wind is blowing, allows to help take advantage of electricity that is generated when renewable energy is not producing electricity.
