考虑供给-需求调控成本动态变化的园区供用能综合优化模型

对于包含柔性负荷的园区级综合能源系统，可通过调整各能源转换设备的出力改变冷、热、电、蒸汽等能源产品的供给量，也可通过需求侧管理调整各类能源产品的实时需求量。各能源转换设备出力调节及需求管控措施均需相应的成本，有必要对冷、热、电及蒸汽等能源产品的生产侧和需求侧进行综合协调。通过构建冷热电气各类能源转换系统与需求调节措施动态成本的数学模型，以供用能综合成本最低为目标，对能源转换设备出力和需求调节进行综合优化。结果表明：同单纯调节能源转换设备出力相比，园区能源转换设备出力与需求综合调控可进一步降低供用能成本。

The Collaborative Optimization Model of Park Energy Supply and Use Considering the Change of Supply - Demand Regulation Cost

For an integrated energy system (IES) of park with flexible load, the production of cold, heat, electricity, and steam can be changed by adjusting energy conversion equipment, and the load can also be changed by demand-side management. All energy conversion equipment operation and demand control measures require corresponding costs. It's necessary for integrated optimization of equipment side and demand side of energy products (such as cold, heat, electricity, and steam) to reduce cost of IES. In this paper, mathematical models for the various types of energy conversion and demand response costs are established, with the goal of minimizing the overall cost of energy supply, to comprehensively optimize the energy conversion system design and demand-side management in IES. The results show that compared with simply adjusting the output of energy conversion system, the coordinated regulation of energy production and demand side of the integrated energy system has the potential to further reduce the cost of integrated energy supply and utilization system.
