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.
