Fire storage frequency regulation has high requirements on battery capacity design, charge and discharge rate, etc., and has strict requirements on grid-connected performance and scheduling flexibility of energy storage systems. The system must simultaneously meet primary and secondary frequency regulation and fast power direct regulation, etc. Multiple operating modes, while the energy storage system is installed in the power plant, the requirements for the safety of the energy storage system itself and the safety of the system operation are also higher.


ed through multi-dimensional simulation optimization with the customer. The 30-day trial operation results showed that the comprehensive frequency modulation performance index increased by 3.4 times, bringing higher benefits to customers; The system adopts the DC safety management design of "battery four-level management, four-level fusing and millisecond-level linkage protection" to ensure safe and reliable operation of the system.


In addition, during the trial operation, Guangdong Electric Power Research Institute conducted rigorous tests on the system's core performance indicators such as grid adaptability, high and low voltage ride-through, and power regulation response, and the system performed excellent in various performance indicators.
