为了提高能源利用效率与实现能源清洁供应，区域综合能源系统已成为支撑能源转型的重要技术。研究掌握区域综合能源多能耦合机理，对未来实现系统的有序规划、运行具有重要研究意义。文中提出了一种区域综合能源系统中具有分布式能源的最优能流模型和方法。提出了基于能源集线器模型并充分考虑能耗（太阳能、燃料油、生物质能）的电力系统、天然气系统、热力系统的优化策略。采用基于内点法对区域综合能源系统优化模型进行求解。通过利用辅助燃烧设备（Supplemental Firing Equipment，SFE）调节热电联产（Combined Heat and Power，CHP）单元的热电比，建立了带有SFE的生物质能CHP模型，从而增加了CHP供能比例，最终实现了系统的经济运行。
英文摘要:
In order to improve energy efficiency and achieve clean energy supply, regional integrated energy systems have become an important technology to support energy transformation. Studying and mastering the multi-energy coupling mechanism of regional integrated energy is of great research significance for the orderly planning and operation of the system in the future. This paper proposes an optimal energy flow model and method with distributed energy in a regional integrated energy system. The optimization strategy of power system, natural gas system and thermal system based on the energy hub model and fully considering energy consumption (solar energy, fuel oil, biomass energy) is proposed. The optimization model of regional integrated energy system is solved based on the interior point method. The heat and power ratio of combined heat and power (CHP) units is adjusted through using supplemental firing equipment (SFE), and a biomass energy CHP model with SFE is established, which increases the CHP energy supply ratio, and the economic operation of the system is realized.
