摘要： 清洁能源消纳是影响园区综合能源系统（park integrated energy system， PIES）可持续发展的问题之一，基于此，文章构建了以设计峰谷分时电/热价为依托的综合型价格需求响应模型和以电转气（power to gas， P2G）、电制冷机（electric refrigerator， ER）、电锅炉（electric boiler， EB）为依托的转换型需求响应模型。首先构建了由能源供应中心和能源转换中心构成的耦合冷、热、电、气的园区综合能源系统及其交易策略；其次，在考虑综合型价格和转换型需求响应的基础上，构建了以出力、需求响应前后能量平衡等为约束条件，以系统净收益最大为目标函数的优化调度模型；然后，从经济和环境两方面构建了绩效评估指标；最后，进行了实例分析，验证了所建模型具有提高清洁能源消纳量和系统经济性的作用。

Abstract: The difficulty of clean energy accommodation is one of the problems affecting the sustainable development of park integrated energy system (PIES). This paper constructs a comprehensive price demand response model based on the design of time-of-use prices of power and heat and the conversion demand response model including power to gas (P2G)， electric refrigerator (ER) and electric boiler (EB). Firstly， a park integrated energy system， which is composed of an energy supply center and an energy conversion center， and its trading strategy， are constructed. Secondly， on the basis of considering the comprehensive price demand response and the conversion demand response， an optimal scheduling model with the objective function of maximum system net income is constructed with the constraints of the energy balance before and after the demand response. Then， the performance evaluation indicators are constructed from economic and environmental aspects. Finally， an example analysis is carried out to verify that the model has the effect of improving clean energy consumption and system economy.

Key words: park integrated energy system（PIES）, comprehensive price demand response, conversion demand response, combined cooling, heating and power（CCHP）, power to gas（P2G）
