摘　　要：微能源网是促进新能源消纳和碳减排的重要载体,可提供电、热、气、氢等多类型的能源,有利于实现多种能源的统一协同调度。首先提出了含高比例风电的低碳微能源网架构,电、热系统通过包含电-热-氢多能转化和存储的能量枢纽互联;其次,综合考虑微能源网对上级网络能源价格及节点边际碳排放强度的响应、微能源网中配电网和热网自身的优化运行、电-热-氢能量枢纽内部灵活调节、终端负荷柔性能量需求,建立了考虑多元协同互动的微能源网多目标优化运行模型。通过分段线性化、二阶锥松弛、多目标加权模糊化处理技术将优化模型转化为易于求解的混合整数二阶锥单目标规划问题。最后,通过电-热-氢能量枢纽将改进的IEEE33节点电力系统和改进的巴厘岛32节点热力系统互联组成微能源网进行仿真验证,结果表明考虑多元协同互动的能源供需在系统运行经济性和低碳性方面具有优势。The micro-energy grid is an important carrier to promote the absorption of new energy and carbon emission reduction.It can provide electricity,heat,gas,hydrogen and other types of energy,which is conducive to realize the unified and coordinated dispatching of various energy sources.In this paper,firstly,we proposed a low-carbon micro-energy grid structure with a high proportion of wind power.The electricity and heat systems are interconnected through an energy hub that includes electricity-heat-hydrogen multi-energy conversion and storage.Secondly,we established a multi-objective optimization operation model of the micro-energy grid regarding multiple synergistic interactions,which comprehensively considers the response of the micro-energy grid to the energy price and the node marginal carbon emission intensity of the upper-level energy network,the optimal operation of the distribution network and the heat network itself in the micro-energy grid,the internal flexible adjustment of the electricity-heat-hydrogen energy hub,and the flexibility of the terminal load.The optimization model is transformed into an easy-to-solve mixed integer second-order cone single-objective programming problem through piecewise linearization,second-order cone relaxation,and multi-objective weighted fuzzification.Finally,we interconnected the improved IEEE 33-node power system and the improved Bali 32-node thermal system to form a micro-energy grid through the electric-thermal-hydrogen energy hub for simulation verification.The results show that the energy supply and demand considering multiple cooperative interaction has advantages in the system operation economy and low carbon.
