Real-time transient stability assessment of electric power systems using pbkp_redictive-SIME based on machine learning

Abstract:

This paper presents a novel methodology based on machine learning for assessing the power system transient stability (TS) in real-time using synchronized phasor measurements as input in order to pbkp_redict the power system TS status related to the single machine equivalent (SIME) results. Based on the probabilistic models of input parameters, such as load variation and the occurrence of contingencies, Monte Carlo-type simulation is performed off-line to iteratively evaluate the system TS responses using the SIME methodology. Afterwards, the database obtained from the off-line simulations is employed for structuring and training an intelligent SIME's TS margin classifier based on support vector machines (SVM) to be used for real-time transient stability assessment (TSA). Besides, the SVM is optimally tuned by using the swarm variant of the mean-variance mapping optimization MVMO S . Several tests are then …
