中文摘要:

      为推动清洁能源供暖，提高北方城市供暖的质量和效率，提出了一种城市换热站热泵补热系统的优化运行策略。首先，对城市换热站热泵补热系统设备进行建模；然后，构建热泵补热系统与电网的互动场景，包括响应峰谷平电价和参与调峰辅助服务市场；接着，建立系统运行成本最低、热网稳定性最优的双目标优化模型，并将其转为单目标优化问题，采用粒子群优化算法进行求解；最后，通过算例进行4种供热方案的对比分析，验证所提模型的经济性和低碳性，为城市供暖的低碳化转型提供了新思路。

英文摘要:

      In order to promote clean energy heating and improve heating quality and efficiency of municipal heating in northern China, an optimal operation strategy of heat pump system in urban heat exchange station is put forward. Firstly, the equipment of heat pump system in urban heat exchange station is modeled；Secondly, the interactive scene between heat pump supplementary heating system and power grid is constructed, including responding to peak-valley average electricity price and participating in peak-shaving auxiliary service market；Then, a double-objective optimization model with the lowest operating cost and the best stability of heating network is established,which is transformed into a single-objective optimization problem and solved by particle swarm optimization algorithm；Finally, four heating schemes are comparatived and analysed through an example, and the economy and low carbon of proposed model are verified model,which provides a new idea for the low carbon transformation of urban heating.
