基于多能互补的综合能源系统多场景规划案例分析

综合能源系统存在冷热电气多种能源形式、多方利益主体、差异化用能需求等特点,如何统筹协调多种能源互补特性,通过源-网-荷-储等各环节灵活配置,实现可再生能源就地消纳,提升系统综合能效,是综合能源规划所面临的关键问题。结合北方某园区综合能源系统规划实例,对多场景规划理念进行了探讨,分别对能源需求预测分析、综合能源站子系统规划场景设计、建设时序及多能互补协同效益等规划环节进行了深入的分析,可为相关区域综合能源系统规划项目提供参考。

Case analysis of multi-scenario planning based on multi-energy complementation for integrated energy system

The integrated energy system has several particular features: multiple energy source types, such as electric power, natural gas, heat(cool) and so on, multiple interest groups, various energy demands, etc.,and the key problem of its planning is how to make the overall cooperation of multi-energy complementation for the flexible configuration of different sections, such as source, grid, load, storage and so on, to promote the local accommodation of renewable energies and enhance the comprehensive energy efficiency of system. With a practical multi-energy system planning for a region in northern China as an example, the concept of multi-scenario planning is discussed and several planning sections are deeply analyzed: the prediction and analysis of energy demands, the scenario design of multi-energy station subsystem planning, the construction schedule and the synergetic benefit of multi-energy complementation, which provides reference for the similar regional multi-energy system planning.
