Calculation of optimal energy flow in a regional integrated energy system taking into account multi-energy coupling
摘要：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:
Abstract：In order to improve energy utilization efficiency and achieve clean energy supply, regional integrated energy systems have become important technologies supporting energy transformation. Studying and mastering the multi-energy coupling mechanism of regional comprehensive energy has important 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 an integrated energy system. An optimization strategy for power systems, natural gas systems, and thermal systems based on energy hub models and fully considering energy consumption (solar energy, fuel oil, and biomass energy) is proposed. An interior point-based method was used to solve the regional integrated energy system model. By using supplementary firing equipment (SFE) to adjust the thermoelectric ratio of the combined heat and power (CHP) unit, a CHP model of biomass energy with SFE was established, thereby increasing the proportion of CHP energy supply. Realized the economic operation of the system.
