【 摘 要 】

To solve the parallel circulating current problem in the operation control of modular energy storage converter, the causes of the parallel circulating current are analyzed, and a new circulating current suppression method based on improved single neuron PID is proposed. The superiority of the method is verified theoretically by building simulation model. The test verification is carried out by developing 50kW power module and 150kW modular energy storage converter prototype. The results show that the method can effectively suppress parallel circulating current and solve the problems of difficult parameter adjustment and poor adaptability to power mutation in traditional PID control.
