    摘 要:为了提高可再生能源的利用率,兼顾综合能源系统的运行经济性及风电、光伏消纳等多个目标,建立了含电转气设备的电、气、热互联的综合能源系统调度模型。以综合能源系统的运行成本、弃风和弃光量最小为目标,利用多目标模糊加权法将多目标问题转换为单目标问题,并遍历权值求解出帕累托解集,再根据熵值法的灰靶决策理论选择兼顾运行经济性和可再生能源利用率的调度计划。通过算例仿真,得出含电转气的综合能源系统可以有效促进可再生能源消纳。

    Abstract: In order to improve the utilization rate of renewable energy, take into account the operation economy of the integrated energy system and the consumption of wind power and photovoltaic power, a comprehensive energy system dispatch model with electricity, gas, and heat interconnection including electricity-to-gas equipment has been established. With the goal of minimizing the operating cost, wind abandonment and light abandonment of the integrated energy system, the multi-objective problem is converted into a single-objective problem using the multi-objective fuzzy weighting method, and the Pareto solution set is solved by traversing the weights, and then based on the entropy method the gray target decision-making theory chooses a dispatch plan that takes into account both operating economy and renewable energy utilization. Through simulation, it is concluded that the integrated energy system containing electricity to gas can effectively promote the consumption of renewable energy.
    Key words: integrated energy system; multi-objective scheduling; fuzzy weighting; gray target decision-making; electricity to gas
