Research on distribution network situation prediction model based on HMM-NSSP model

At present, most of the situation prediction models are established for the planning of large power grids, but a complete set of distribution network situation prediction models have not been formed. From the perspective of combining theory with practice, a real-time network security situation prediction model HMM-NSSP based on Hidden Markov model is proposed. The parameters are dynamically modified through the real-time performance of network nodes to realize the real-time monitoring and prediction of the security situation of the whole distribution network. The effectiveness and superiority of the model are verified by simulation experiments.
