Research on Optimal Allocation of Electric-Cool-Heat Integrated Energy System Considering Reliability
2020
Optimizing the capacity allocation of the integrated energy system (IES) can promote the cascade utilization of multiple energy sources of electric cooling and heating, which is an important research direction of IES planning and design. In this paper, the lowest operating cost and the highest reliability of the IES are taken as the objective function, and a variety of load balancing constraints and equipment operating constraints are considered, the output strategy of each unit is formulated, an optimal allocation model is established for IES with various energy sources. Based on the differential evolution (DE) algorithm, MATLAB simulation is carried out. First, three scenes are constructed based on different equipment types, and the role and feasibility of renewable energy consumption, energy storage and CCHP are gradually studied. Finally, the optimization results of the multiple scenes are analyzed and compared. The effectiveness of the model solving method is confirmed by the optimized results.
