含混合储能的冷热电联供系统运行策略及容量配置

冷热电联供系统是分布式能源未来主要发展方向和形式。建立了含混合储能的冷热电联供系统多目标优化模型,考虑设备初始投资成本和维护成本,分析在"以电定热"和"以热定电"不同运行策略下混合储能初始容量及总容量配置对系统能源性、经济性、环境性评估指标的影响,得出储能容量最优配置及系统运行策略,并与不含储能系统对比验证。通过算例验证表明,合理的储能容量配置及运行策略选择有助于提高系统能源利用率,减少二氧化碳排放和运行成本,为冷热电联供系统规划运行提供一定的理论和技术参考。

Operation Strategy and Capacity Configuration of CCHP System with Mixed Storage Energy

CCHP system was the main direction and form of the future development of distributed energy. The multi-objective optimization model of CCHP system with hybrid energy storage was established, considering the initial investment cost and maintenance cost of the equipment, the impact of initial capacity and total capacity allocation of hybrid energy storage on the energy, economy and environmental evaluation indexes of the system under operation strategies of "Setting heat with electricity" and "Setting electricity with heat". The optimal allocation of energy storage capacity and system operation strategy were obtained and compared with those without energy storage. Examples show that reasonable allocation of energy storage capacity and selection of operation strategy were helpful to improve energy utilization, reduce carbon dioxide emissions and operation costs, and provide a theoretical and technical reference for the planning and operation of CCHP system.
