摘要
针对综合能源系统中存在潜在的可调度资源,基于能源集线器构建包含储能、燃气轮机发电系统、柔性负荷等在内的社区综合能源系统数学模型。该模型综合考虑用户侧柔性负荷的可平移、可转移、可削减的负荷特性。最终建立以总运行成本最小为目标的综合能源系统供需联合日前优化调度模型,采用Yalmip工具箱和Cplex求解器对算例进行求解,得到3种场景下柔性电、热负荷参与调度的优化结果,并对比分析电热独立调度的经济效益。仿真结果表明:电热耦合调度,柔性电、热负荷的参与互动能明显降低系统运行成本,减小负荷峰谷差,缓解高峰用电压力。
Aiming at the potential dispatchable resources in the integrated energy system,this paper builds a mathematical model of the community integrated energy system based on the energy hub,including energy storage,gas turbine power generation system and flexible load,etc. The model takes into account the load characteristics of user-side flexible load,which can be shifted,transferred and reduced. Finally,a joint optimization model for the supply and demand of integrated energy system with the goal of minimum total operating cost is established. The Yalmip toolbox and Cplex solver are used to solve the example,and the optimization results of flexible electric and thermal load participation scheduling in three scenarios are analyzed,and the economic benefits of independent electrical and thermal dispatch are compared and analyzed. The simulation results show that the participation of electrical and thermal coupled scheduling and flexible electric or thermal loads can significantly reduce the system operating cost,reduce the load peak-to-valley difference,and relieve peak power consumption pressure.
