摘　　要：为了高效协调新型配电系统电源和负荷功率平衡,提出了一种基于多元信息和边缘计算的源荷功率监测协调策略。首先,分析了新型配电系统的特点和网格划分方法、协调其内部电源和负荷功率所涉及的多元信息构成;其次,通过在网格内部署具备边缘计算功能的智能终端,给出了前端智能终端和后端监控系统相互配合协调网格内源荷功率平衡的策略,设计了多元信息监测通信方案;最后,选取相关设备对所给策略进行了试验验证,并与传统配电网系统源荷协调策略进行了对比。结果表明:将复杂的新型配电系统进行网格划分,能够利用前端智能终端在1 s内、后端监控系统在10 s内协调网格内源荷功率平衡;网格内电能损耗使后端监控系统协调时间的变化值小于0.5 s、对前端协调策略的影响可以忽略不计;将不同协调手段相结合,具有协调时间短、难度低的优势。所给策略解决了传统配电系统以系统整体进行集中协调源荷功率时信息采集、计算量大和延时长的问题,能够提高源荷协调的效率和可靠性,对快速实现系统整体源荷功率平衡、保障其稳定运行具有重要的参考价值。In order to efficiently coordinate power supply and load balance of novel distribution system,a source load power monitoring coordination strategy was proposed based on multivariate information and edge computing.Firstly,the characteristics and grid division of the novel distribution system were analyzed,as well as the multivariate information composition involved in coordinating its internal power supply and load power,and a multivariate information monitoring and communication scheme was designed.Secondly,the scheme of coordination between front-end intelligent terminals and the back-end monitoring system to balance internal load and power of the grid was proposed by deploying intelligent terminals with edge computing function in the grid.Finally,relevant equipment was selected for experimental verification of the given strategy,and compared with the traditional distribution network system source load coordination strategy.The results show that dividing the complex novel distribution system into grids can utilize front-end intelligent terminals to coordinate internal load power balance within 1 s and back-end monitoring systems within 10 s;The power loss of the grid causes the change in coordination time of the backend monitoring system to be less than 0.5 s,and the impact on the front-end coordination strategy can be ignored;Combining different coordination methods has the advantages of short coordination time and low difficulty.The given strategy solves the problems of large information collection and calculation workload,and long delay in centralized coordination of source load power in traditional distribution systems.It can improve the efficiency and reliability of source load coordination and has important reference value for quickly achieving overall source load power balance of the system and ensuring stable operation of the system.
