摘要：
In order to improve the operation efficiency of the combined cooling heating and power system (CCHP) in distributed energy system (DES), the hybrid energy storage technology combining battery energy storage system and heat storage system is proposed in this paper to be applied to DES with photovoltaic electric (PV). According to the mathematical models of gas turbine, PV system and other devices in DES, the energy flow model of the DES is first established in MATLAB and the boundary of the hybrid energy storage system (HESS) is determined. Moreover, the Power-Load-based control strategy is carried out and improved by researching the regulation effect of HESS and applied to the new DES which includes HESS and PV. Finally, the actual examples are analyzed to compare the load rate and running efficiency of the CCHP between traditional DES and the new DES. The results show that HESS could reduce the configuration capacity of CCHP and greatly improves its operation efficiency as well as the energy utilization efficiency of the overall system.
