一流城市配电网的灵活适应性评价指标及计算方法
|
摘要
一流城市配电网的建设是国家、城市、电网的共同战略需求,但多元分布式电源和新兴负荷的增多,增加了配电网运行的不确定性,再加上可能存在的各种扰动或故障,对一流城市配电网的灵活适应性提出了更高的要求。立足配电网发展现状,进行一流城市配电网的内涵分析;对一流配电网灵活适应性进行特性分析,从配网侧、负荷侧和电源侧阐述各类灵活性资源;面向配网侧、负荷侧和新能源发电,提出一流城市配电网的灵活适应性评价指标体系及计算方法;最后针对修正的IEEE 33节点算例系统,计算不同场景设定下的部分指标值,定量评估不同场景下配电网的灵活适应性。所提一流城市配电网的灵活适应性评价指标及计算方法,对当前一流城市配电网的推广建设具有重要的指导作用。
The construction of first-class distribution network is a strategic demand of the state, the city and the power grid. However, the increase of multiple distributed power sources and emerging loads have increased the uncertainty of distribution network operation. Meanwhile, considering the existence of various disturbances or faults, the requirements for the flexible adaptability of first-class distribution network have been put forward. Based on the status of distribution network, the connotation analysis of first-class distribution network is carried out. The flexible adaptability of the first-class distribution network is explained and various flexible resources are introduced from the distribution network side, load side and power supply side. Then, the flexible adaptability evaluation index system and calculation method for the first-class distribution network are proposed from the distribution network side, load side and renewable energy side. Finally, some index values under different scenes are calculated for the modified IEEE 33-node system. Different flexible adaptability of the distribution network can be quantitatively evaluated in different scenarios. The flexible adaptability evaluation index and calculation method for the first-class distribution network will play a guiding role for the promotion and construction of the first-class distribution network.
