Optimization and Analysis of Distributed Energy System with Energy Storage Device
Aiming at distributed energy system (DES) with energy storage device, the mathematical models of major equipments are established in this paper. With the objective functions of the daily minimum operation cost and the minimum equipment quantity, a mixed integer nonlinear multistage objective function is established, which is solved by the means of dynamic programming and penalty function and then the system optimization is completed.According to the case of a hospital in Tianjin, the optimized result is compared with the other two modes, which are DES without energy storage device and sub-production system (the existing system of the hospital).The result shows that the system with energy storage device is better than the system without energy storage device, and the economy of DES is superior to sub-production system significantly.
