【摘要】：对配电网运行效率的评价有利于把握电网运营现状、提高决策水平、引导投资方向。针对目前对配电网运行效率评价存在的一些问题,首先对影响配电网运行效率的因素进行了分析,并提出基于负荷持续曲线的设备运行效率评价模型,该模型综合考虑电网安全性和设备运行经济性,提出了最大可输送负荷、基于安全运行限值的平均负载率、安全风险惩罚因子等全新指标;分析了负荷持续曲线形状对安全风险惩罚因子的影响;在设备运行效率基础上提出系统运行效率和系统协调度的计算方法,以反映配电网整体运行效率及各层级设备运行效率之间的协调程度。算例分析结果验证了模型的可行性和有效性。
[Abstract]:The evaluation of distribution network operation efficiency is beneficial to grasp the current situation of power network operation, improve the level of decision-making, and guide the investment direction. Aiming at some problems existing in the evaluation of distribution network operation efficiency at present, this paper analyzes the factors that affect the distribution network operation efficiency, and puts forward the equipment operation efficiency evaluation model based on the load continuity curve. Considering the security of the power network and the operation economy of the equipment, the new indexes, such as the maximum transportable load, the average load rate based on the safe operation limit, the safety risk penalty factor and so on, are put forward in this model. The influence of load duration curve shape on safety risk penalty factor is analyzed, and the calculation method of system operation efficiency and system coordination degree is put forward on the basis of equipment operation efficiency. To reflect the overall operational efficiency of the distribution network and the level of coordination between the operational efficiency of equipment. The feasibility and validity of the model are verified by an example.
