【摘要】：随着配电网智能化建设水平的提高,智能配电系统的运行与控制将受到大量不确定因素的影响。如何应对与控制不确定因素对供电特征所带来的不确定影响是智能配电网建设与运行面临的本质问题之一。首先,分析智能配电网所包含的源、网、荷、信息系统与外部异质能源系统等五类不确定因素及其对电压稳定性、电能质量等供电特征的不确定影响,概括了智能配电网不确定性分析与优化控制的研究框架。然后,分别从不确定因素特性及建模、因果式与关联式不确定性分析、供电特征不确定运行优化及其支撑技术三个方面进行了梳理和总结,并展望了各自的发展方向及其面临的挑战,以期为后续研究提供借鉴。
[Abstract]:With the improvement of intelligent construction level of distribution network, The operation and control of intelligent distribution system will be affected by a large number of uncertain factors. How to deal with and control the uncertain influence of uncertain factors on power supply characteristics is one of the essential problems in the construction and operation of smart distribution network. This paper analyzes five kinds of uncertain factors, such as source, network, load, information system and external heterogeneous energy system, which are included in smart distribution network and their uncertain influence on voltage stability, power quality and other power supply characteristics. The research framework of intelligent distribution network uncertainty analysis and optimization control is summarized. In this paper, three aspects of uncertain operation optimization of power supply and its supporting technology are summarized, and their development directions and challenges are prospected in order to provide reference for future research.
