摘要(Abstract)：

在“双碳”目标下新型配电网具有典型平衡区的特征，提升配电网平衡区的平衡能力对保障新型配电网经济高效运行具有重要的工程意义。首先，考虑联络线利用率、自平衡度、可调能源占比、可控负荷占比和可再生能源利用率，构建5项平衡指标。其次，采用直觉模糊交叉熵算法计算指标权重，通过加权得到综合判别平衡因子，用于综合量化平衡能力。然后，以全寿命周期成本最小和综合判别平衡因子最大为目标，设备运行、配置和平衡指标作为约束条件，构建多目标优化配置模型，提出考虑分时电价的能量优化运行策略。最后，以工程实测数据为例进行了仿真，结果验证了所提方法的有效性。
The new distribution networks under the “dual carbon” goal have the characteristics of the typical balance areas. The balance capacity improvement of the distribution network balance area is of engineering significance to ensure the economical and efficient operation of new distribution networks. Firstly, five balancing indexes are constructed by considering the utilization ratio of tie lines, self-balancing degree, the proportion of schedulable energy, the proportion of controllable load, and the renewable energy utilization ratio. Secondly, an intuitionistic fuzzy crossentropy algorithm is used to calculate the index weights. A comprehensive discriminant balancing factor is obtained by weighting and used to quantify the balancing capacity comprehensively. Afterward, with the goal of minimizing the life cycle cost and maximizing the comprehensive discriminant balancing factor, and taking the equipment operation, configuration, and balancing indexes as constraints, a multi-objective optimal configuration model is constructed, and an optimal energy operation strategy considering time-of-use tariffs is proposed. Finally, the simulation on measured engineering data is conducted. The results verify the effectiveness of the proposed method.
