[Abstract]:Microgrid usually uses energy storage system to suppress DC bus power fluctuation caused by load change. Li-SC HESS, a hybrid energy storage system for lithium batteries and supercapacitors, is used to meet both the power and energy requirements caused by load changes. The model structure of hybrid energy storage system is studied, and a PCH strong tracking control method for coordinated power allocation of HESS is proposed. The simulation model of hybrid energy storage system of optical microgrid is established in Simulink by Simscape, and compared with the conventional double-closed-loop linear control strategy of micro-grid. The simulation results show that the proposed HESS control strategy can effectively reduce the charge and discharge times of lithium battery, smooth the charging and discharging process, prolong the service life, and improve the performance of hybrid energy storage system.
