A Study on Protection system for Energy Storage System

초록

Before the ESSs are installed, protection tests are performed to guarantee the safety and the quality of the ESS. Various protection devices are installed to protect the ESS and power facilities in substation. These devices guarantee the safety and the quality of the ESS. Maintenance is possible by the resistor of the ESS. User can check the fault record of the ESS in real time by the monitoring device. And the ESS has been improved for the safety.
