| Abstract | The invention relates to a protection method of an energy storage system and the energy storage system. The protection method of the energy storage system is applied to an off-grid mode or a virtual synchronous generator mode of the energy storage system, and the protection method of the energy storage system comprises the following steps: obtaining a detection parameter value of the energy storage system and a detection threshold range corresponding to the detection parameter value; when the detection parameter value exceeds the detection threshold value range, shutdown protection timing is started, and the shutdown protection timing has timing duration; and when the duration that the detection parameter numerical value continuously exceeds the detection threshold range reaches the timing duration, shutdown operation is executed. According to the method, the shutdown protection timing is set when the detection parameter value exceeds the detection threshold value range, and whether the current detection para |
