The energy storage system consists of several major S components, allowing the entire energy storage system to operate. What are the roles of STS, PCS, ATS, EMS, and BMS in the entire system. Below, we will introduce the specific functions of these S one by one:

STS: English translation: Static Transfer Switch, Chinese name: Static Transfer Switch. The working principle of STS is based on the demand for power switching. When the main power supply fails or fails, STS can automatically switch the load from the main power supply to the backup power supply to maintain continuous power supply

PCS: Power Conversion System, also known as bidirectional energy storage inverter, is the core component that realizes the bidirectional flow of electrical energy between the energy storage system and the power grid. It is used to control the charging and discharging process of batteries and perform AC/DC conversion

EMS: Energy Manager System, also known as Energy Management System in Chinese, is responsible for the control strategy of energy storage systems. The control strategy affects the decay rate and cycle life of batteries in the system, thereby determining the economic efficiency of energy storage; It also monitors faults and anomalies during system operation, playing an important role in timely and rapid protection of equipment and ensuring safety

BMS: Battery Manager System, also known as Battery Management System in Chinese, measures the basic parameters of a battery, including voltage, current, temperature, etc., to prevent overcharging and discharging, extend the battery's service life, calculate and analyze the battery's SOC (remaining battery capacity) and SOH (battery health status), and report abnormal information in a timely manner

Automatic Transfer Switch, also known as Automatic Transfer Switch in Chinese, is a switching device that automatically switches the load circuit from one power source to another (backup) power source in an emergency power supply system to ensure the continuous and reliable operation
