| 摘要: |
| 能量枢纽(EH)可以促进不同形式的能源载体协同运行，是加快泛在电力物联网关键技术研究的重点。提出了一种基于非合作博弈的多EH优化运行方法，将包含多能源系统的单个园区抽象为一个EH，对EH中的能源生产、转换及储能设备进行建模，建立多能协同运行的EH框架；在此基础上，构建基于纳什均衡的多EH非合作博弈模型，各EH以日运行成本最小为目标函数与其他EH参与博弈，分析各EH中设备出力和负荷平衡情况。基于MATLAB进行仿真运行，结果表明多个EH之间能充分利用区域间负荷互补特性，使各EH在优化个体运行成本的同时，提高系统的灵活性。 |

| Abstract: |
| The EH(Energy Hub) can promote the cooperative operation of different forms of energy carriers and is the key point to accelerate the research on key technologies of ubiquitous power internet of things. A non-cooperative game-based optimal operation method of multiple EHs is proposed. The single park containing multi-energy system is abstracted into an EH, and the energy production, conversion and storage equipment in EH are modeled, so as to establish the EH framework for multi-energy cooperative operation. On this basis, the non-cooperative game model of multiple EHs based on Nash equilibrium is constructed. Each EH participates in the game with other EHs with the objective function of minimizing daily operation cost, and the equipment output and load balance in each EH are analyzed. Simulative results based on MATLAB show that multiple EHs can make full use of the complementary characteristics of inter-regional loads, so that each EH can optimize the individual operation cost and improve the system flexibility. |
