摘要: |
高比例新能源含电转氢综合能源系统中,新能源不确定性对系统产生较大冲击与影响,系统灵活性充裕度成为必须考虑的因素。因此,提出一种考虑灵活性供需平衡约束的含电转氢综合能源系统鲁棒优化调度方法。建立含电转氢综合能源系统各类灵活性资源供需模型,对各类灵活性资源调节能力进行了描述。采用鲁棒优化中基数性不确定集合方法描述风电预测误差,将风电预测误差和经济调度决策者视为博弈的竞争。依据零和博弈理论,建立计及灵活性供需平衡的含电转氢综合能源系统鲁棒优化模型。在鲁棒优化的基础上,分析了系统内新能源不确定性及灵活性供需平衡对于系统的影响。对东北某实际含电转氢综合能源系统的仿真分析表明,所提方法可有效应对风电出力的不确定性,兼顾系统的经济运行和灵活性。 |

Abstract: |
In the integrated energy system with a high proportion of new energy including power to hydrogen (P2H), the uncertainty of new energy has a great impact on the system, and the flexibility and adequacy of the system have become important factors. A supply and demand model of various types of flexible resources in an integrated energy system with P2H is established, and the flexible adjustment capability of the system is described. The base uncertainty ensemble method in robust optimization is used to describe the wind power forecast error. The forecast error and economic dispatch decision makers are regarded as the competition of the game. Based on zero-sum game theory, a new robust optimization model of an integrated energy system with P2H considering flexibility balance is established. On the basis of robust optimization, the influence of new energy uncertainty and flexible supply and demand balance in the system is analyzed. A simulation analysis of an actual integrated energy system with P2H in Northeast China shows that the proposed method can effectively deal with the uncertainty of wind power output, and take into account the economic operation and flexibility of the system. |
