At present

the user side information acquisition capability of the power grid is relatively backward. The lack of customer load type information and the unclear composition of the grid load seriously restrict the optimization and improvement of customer service.The non-intrusive load identification technology only collects the total current and voltage data of customers at the entrance

and uses advanced algorithms to realize the accurate identification of the indoor load

which is an effective way to break the bottleneck of customer load information acquisition.This paper briefly introduces the mainstream technical route of non-intrusive load identification technology

analyzes and prospects the typical application scenarios of this technology for grid enterprises and customers

and introduces its application in Hunan power grid.
