    分析了当今配电网规划的需求,确立了柔性负荷资源纳入规划的重要作用。从能量互动方式、调度响应方式、用户及设备类型3个角度提出柔性负荷的分类方式与分类结果。针对柔性负荷接入对配电网规划的影响,从负荷预测、电力平衡、规划优化、规划方案评估四大环节分析了现有规划方法的适应性与不足之处,并提出相应的改进思路与建议。最后围绕柔性负荷建模、配电大数据挖掘与应用等新型关键技术进行了综述,并对未来配电网建设发展进行了总结与展望。

    Abstract:

    First of all, this paper analyzes the demand of current distribution network planning, and establishes the important role of bringing the flexible load resources into planning. Furthermore, the classification methods and results of flexible load are proposed from three aspects, i.e. energy interaction mode, scheduling response mode, user and equipment type. Then, aiming at the influence of access of flexible load on the distribution network planning, the adaptability and shortcomings of the existing planning methods are analyzed from four aspects, including load forecasting, power balance, planning optimization and planning evaluation, and corresponding improvement ideas and suggestions are put forward. Finally, the new key technologies such as flexible load modeling, big data mining and application are summarized, and the future development of distribution network construction is summarized and prospected.
