Abstract: With the continuous development of energy storage technology and the construction of large-scale energy storage power station, the test of energy storage station is necessary for further study to ensure the safety and normal operation after interconnecting to power grid. Firstly, test indicators and specific testing methods are analyzed based on the configuration of energy storage station. Then,an integrated test bench is developed based on the integrity of energy storage station and the interconnecting network. The hardware architecture and program structure of the proposed test bench and the function design are described in detail. Finally, according to the project scenario of test bench, the wiring diagram of test devices is described and the implementation of the test program is proposed.The practical application shows the feasibility of the proposed test bench and its supporting program.
