Research on Data Mining Algorithm of Power Grid Based on Cloud Computing

There are a large amount of complex data in the power grid database. How to use these data reasonably and efficiently and solve the problem of power grid operation safety has become an urgent need. Based on the principle of association rule mining technology, this paper realizes the mining of the potential information of the massive data of the power grid database through the improved Apriori algorithm., The improved algorithm innovation introduces two factors of efficiency and interest, so that strong association rules can be screened more accurately. In addition, in view of the large number of candidate sets of the Apriori algorithm, which is not conducive to the shortcomings of later convergence, an early pruning mechanism is introduced. Thereby improving the efficiency of the algorithm for mining information. Finally, the effectiveness and accuracy of the method are verified through experiments.
