摘要
基于能源互联网框架,提出了一种计及人体舒适度和柔性负荷的综合能源协同优化调度方法。首先,从用户需求侧的角度研究能源使用特性,将柔性负荷分为可转移负荷、可削减负荷以及可转换负荷,分别建立数学模型,并分析其经济性;然后,根据建筑热物质特性,构建了建筑等效热阻模型,用于分析冷/热功率与人体舒适度之间的关系;最后,考虑人体舒适度和用户侧柔性负荷,以综合能源服务商运行收益最大为目标函数,得到了园区级综合能源协同优化调度结果,结果表明所提模型可提高经济性并促进新能源的就地消纳。
Based on the energy internet framework,an integrated energy collaborative optimal dispatch method considering human comfort and flexible load is proposed.Firstly,the energy usage characteristics are studied from the perspective of the user demand,flexible loads are divided into transferable loads,reducible loads and convertible loads.The mathematical models are established according to these loads respectively,and their economic efficiencies are analyzed.Secondly,a thermal resistance model is constructed according to the thermal properties of building to analyze the relationship between cold/heat power and human comfort.Finally,considering the human comfort and user-side flexible load,taking the maximum operating revenue of integrated energy service providers as the objective function,the results of the park-level comprehensive energy collaborative optimization scheduling are obtained,which shows that the proposed model can improve economic efficiency and promote local consumption of new energy sources.
