Abstract

See full text

The invention provides a parameters tuning method of energy storage system and the energy storage system, and the method comprises the following steps: using PID control module to construct a closed-loop control subsystem of energy dispatching; acquiring PID initial parameters according to the energy dispatching model of the energy storage system; setting an adaptive model in the PID control module, and processing the PID initial parameters through the adaptive model to obtain PID adjusted and modified parameters; using the PID adjusted and modified parameters to modify the PID parameters and get the PID tuning parameters. What's more, the system comprises a battery module, a bidirectional converter device, an energy dispatching subsystem and a closed-loop control subsystem; and the closed-loop control subsystem is provided with a PID control module, and the PID control module is provided with an adaptive model for realizing the parameters tuning method of the energy storage system. In addition, the invention can realize the parameters tuning of the energy storage system, so that the control can adapt to the characteristics of the distributed energy storage system, deal with the uncertainty to achieve better control effect, and reduce the failure rate and maintenance cost.
