Abstract: Under the conditions of big data in power industry, the application of data mining technology ran through each link of deliver, transmission, transfer, distribution and usage. Introduction was made to the application of classification analysis, correlation analysis, clustering analysis and anomaly detection etc intelligent algorithms in thunder and lightning prediction of power transmission system, analysis of equipment operational condition, fault early warning and risk profile of power distribution system, user electro-behavioral characteristic clustering, electricity market behavioural analysis, load and electricity price prediction in electricity market and so on. The data mining technology could improve effectiveness in power grid remarkably and it is one of the core technologies for future intelligent power grids.
Key words: data mining; power transmission system; power distribution system; interaction with power; electricity market
