According to the features of the Energy Storage System (ESS) under grid-connected mode, a fault diagnosis and treatment strategy is proposed, which is especially designed for the MW-level ESS connected to the grid. On the basis of the study of the main structure and operation modes of the ESS, as well as its control strategy, the theoretical analyses of the ESS with different fault locations are made and the simulation verifications are proceeded, considering the distinctive fault features of the ESS. Using the analyses and summaries of the simulation results, a novel protection strategy, which is suitable for the large-scale ESS, is proposed and proved to be effective after the test and simulation verification. This protection strategy and simulation results of the grid-connected ESS can be useful and provides reference value for designing and configuring the protection of the MW-level ESS.
