摘要： 风电、光伏并网装机容量的快速增长给电网的安全运行带来了巨大挑战，挖掘电网灵活性资源是保证新能源健康发展的有效途径。为此，提出了一种计及灵活资源调节潜力的高压配电网新能源接纳能力评估方法。首先，基于模糊C均值聚类算法生成风电、光伏和负荷典型场景集；然后，计及配电网水电和网架的灵活性，综合考虑系统的正常运行状态和N–1预想故障状态，以配电网新能源接纳能力最大为目标函数建立新能源规划模型；最后，选取某地区110 kV高压配电网进行算例分析，验证了所提模型及方法的有效性。

关键词: 电源灵活性, 网架灵活性, 新能源规划, 典型场景, N–1预想故障状态

Abstract: The rapid growth of grid-connected installed capacity of wind power and photovoltaic power has brought great challenges to the safe operation of the power system. Exploiting the flexible resources of the power grid is an effective way to ensure the healthy development of renewable energy. Therefore, this paper proposes an evaluation method for accommodation capacity of high voltage distribution networks considering the regulation potential of flexible resources. Firstly, a set of typical scenarios of wind power, photovoltaic and load are produced based on the fuzzy C-means clustering algorithm. Then, taking into account the flexibility of hydropower and power grid, a renewable energy planning model is established with the maximum renewable energy accommodation capacity of distribution networks as objective and with a comprehensive consideration of the normal operation states and the N–1 contingency states of distribution networks. Finally, the effectiveness of the proposed model and method are verified through case study of an 110 kV high voltage distribution network.

Key words: generation flexibility, grid flexibility, renewable energy planning, typical scenarios, N–1 contingency states
