考虑热网与需求响应的综合能源系统优化调度

Optimal Scheduling of Integrated Energy System Considering Heat Network and Demand Response

针对需求响应不确定性给综合能源系统安全经济运行带来的挑战,提出一种考虑热管网传输与需求响应的多区域综合能源系统协同优化调度模型。首先,对热网的能量传输模型进行精细化建模;其次,对综合负荷采取需求响应策略,对可再生能源出力不确定性采取信息间隙决策理论的方法来进行处理;最后,以综合能源系统的调度成本与碳排放惩罚最低为优化目标,综合考虑各类约束条件,提出了综合能源系统日前运行调度方案。通过算例分析,证明了所提模型能够提高系统的经济性和对可再生能源的消纳能力。

Aiming at the challenge of demand response uncertainty to the safe and economical operation of integrated energy system,a cooperative optimal scheduling model of multi-region integrated energy system considering thermal pipe network transmission and demand response was proposed.Firstly,the energy transmission model of heat network was modeled in fine detail.Secondly,the demand response strategy was adopted for the comprehensive load,and the information gap decision theory was adopted to deal with the output uncertainty of renewable energy.Finally,the day-ahead operation scheduling scheme of the integrated energy system was proposed with the minimum dispatching cost and carbon emission penalty as the optimization objective,and various constraints were considered comprehensively.An example analysis proves that the proposed model can improve the economy of the system and the ability to absorb renewable energy.
