The Optimal Scheduling of Solar-Wood-Storage Microgrid System Considering the Operation Characteristics of the Isolated Island Mode

As renewable energy advances, the microgrid system faces the problem of insufficient consumption of renewable energy. In addition, the microgrid is developing rapidly, but the microgrid needs to operate independently from the main network when encountering an emergency. Therefore, in this paper, the operation models of each power source for solar-wood-storage units are established. The objective optimization model is established at the minimum economic expense serving as the target function. Using the CPLEX solver in MATLAB and YALMIP, the optimal scheduling of the solar-wood-storage micro grid system is obtained. The results show that the method not only enhances the absorption ability of the system and reduces the operating cost, but also ensures the ability of isolated island operation.
