Optimal Scheduling of Regional Integrated Energy System Based on Different Working Modes of Electric Boiler with Thermal Storage

针对区域综合能源系统的优化调度中未考虑各设备在不同工作模式下运行给系统带来的影响的现状,研究基于蓄热电锅炉不同工作模式的区域综合能源系统优化调度方法。以系统运行成本最小化为目标,综合考虑设备维护费用与可再生能源发电收益,并采用分时电价制度,建立以蓄热电锅炉为主体的区域综合能源系统优化调度模型。采用YALMIP工具箱和商业软件CPLEX在MATLAB中进行求解,求出了系统内蓄热电锅炉不同工作模式下各个单元各时段的出力情况以及总运行费用。通过仿真算例验证了所提模型和方法的可行性与合理性,仿真结果表明,含有蓄热电锅炉的区域综合能源系统可以通过改变蓄热电锅炉的工作模式,提高系统运行的经济性和灵活性。

The optimal scheduling method of regional integrated energy system based on different working modes of electric boiler with thermal storage is studied in view of the current research in this area in which the influence of the different operating modes of equipment on the system is not considered.Aiming at the system minimum operating cost considering equipment maintenance cost and the renewable energy generation income,adopting the time sharing price system,the optimal scheduling model of the regional integrated energy systems based on the electric boiler with thermal storage is established.The YALMIP toolbox and the commercial software CPLEX are used in MATLAB to find out the output and the total operating costs of each unit under different working modes of the electric boiler with thermal storage in the system.The simulation results show that the regional integrated energy system containing the thermal storage boiler can improve the economy and flexibility of the system by changing the working mode of the thermal storage boiler.The feasibility and rationality of the proposed model and method are verified.
