【摘要】：本文研究综合能源系统的优化规划问题,以提高其综合能源利用效率。首先,建立了以电为核心的综合能源系统规划两层优化模型,系统运行调度优化模型以及系统规划优化模型,以系统优化运行指标作为系统规划优化的依据。该模型分别以经济性和环保性最优为目标,重点考虑了在采暖期和空调期综合能源系统的运行约束。其次,针对两层优化模型分别提出了适合的求解算法,禁忌搜索算法和粒子群算法。最后,给出算例验证本模型和算法可得到经济性和环保性目标下的综合能源系统优化规划方案。两种准则下的规划方案存在矛盾,经济性准则下倾向配置储能设备以充分利用分时电价,而环保性准则倾向配置其他高能效的供能设备。

[Abstract]:In this paper, the optimization planning of integrated energy system is studied in order to improve the efficiency of comprehensive energy utilization. Firstly, the two-layer optimization model of integrated energy system planning, the optimization model of system operation and scheduling and the optimization model of system planning are established, and the optimal operation index of the system is taken as the basis of system planning optimization. The model aims at the optimal economy and environmental protection, and focuses on the operation constraints of the integrated energy system during the heating period and the air conditioning period. Secondly, suitable algorithms, Tabu search algorithm and particle swarm optimization algorithm, are proposed for the two-layer optimization model. Finally, an example is given to verify that the model and algorithm can obtain the optimal planning scheme of integrated energy system under the goal of economy and environmental protection. There is a contradiction between the planning schemes under the two criteria. Under the economic criterion, the energy storage equipment is inclined to be allocated to make full use of the time-sharing electricity price, while the environmental protection criterion tends to configure other energy-efficient energy supply equipment.
