Analysis of the correlation between characteristic of equivalent load and power loss in smart distribution grid

There are many kinds of characteristics of smart distribution grid, such as the complex structure, the complexity of the users, and the factors that affect the power grid loss, which not only related to the spatial distribution of the load, but also the load on the time scale of the power changes. Aiming at the relationship between the load and the network loss in the smart distribution grid, the relationship between the load and the network loss is taken into consideration, and the deep intrinsic relationship between the load and the loss is extracted and the corresponding temporal and spatial characteristic parameters are presented. Based on the spatial parameters and time parameters of the relationship between the equivalent load and the network loss, a time-space characteristic analysis model of equivalent load is established. Based on the data of a regional distribution network in Jiangsu Province, the correlation between the equivalent load and the network loss is analyzed, and its feasibility is verified. And to analyze its correlation to explore the deep link between load and loss.
