Abstract

Abstract: As a high-power energy storage device, super capacitor (SC) is applied in micro-grid energy storage, secondary frequency regulation and peak load shifting in power system, and the research of which has become a hotspot. A second-order model of SC monomer suitable for the grid simulation was established, and the parameter identification using the charge and discharge experiment data under constant current and constant power modes was conducted based on genetic algorithm. A SC energy storage system has been set up in Simulink/Matlab based on the established second-order model of SC. The integrated dynamic equivalent model of SC energy storage system was established by steady-state and transient analysis of the 4-node grid simulation system containing SC, and parameters identification was conducted with genetic algorithm. The integrated dynamic equivalent model has been proven to have good description ability, parameter stability and applicability by co-simulation.
