摘要

为提高源荷匹配度,平抑负荷波动,该文提出计及需求响应负荷和地源热泵出力的综合能源系统优化调度模型,研究柔性负荷与地源热泵在调度顺序不同的情况下对系统的影响。首先,以系统的经济成本和环境成本最小为目标,建立综合能源系统优化调度模型优化各设备的出力。其次,在考虑新能源机组出力不确定性的基础上,利用地源热泵装置转换效率高的特点改善能源互补能力并使其作为一种可调度资源参与系统的调度。最后,在需求侧将柔性负荷分为可转移、可削减负荷作为可调度资源参与调度,平滑负荷曲线。通过算例分析可得：不考虑可调度资源出力顺序的情况下,能有效提高系统的经济和环境效益以及源荷匹配能力。

Abstract

In order to improve the source-load matching degree and suppress the load fluctuation, this paper proposes an optimization scheduling model of integrated energy system taking into account the demand response load and the ground source heat pump output, and studies the influence of flexible load and ground source heat pump on the system under different scheduling sequence. Firstly, the optimization scheduling model of integrated energy system is established to optimize the output of each equipment in order to minimize the economic and environmental costs of the system. Secondly, on the basis of considering the uncertainty of the output of the new energy unit, the energy complementarity of the ground source heat pump is improved by using the characteristics of high conversion efficiency of the ground source heat pump and the energy complementarity is made to participate in the system scheduling as a kind of dispatchable resource. On the demand side, flexible loads are divided into transferable and reducable loads as schedulable resources to participate in scheduling and smooth the load curve. The results show that the economic and environmental benefits and source-load matching ability of the system can be effectively improved without considering the output order of the dispatchable resources.
