Multilabel learning for the online transient stability assessment of electric power systems

Abstract: Dynamic security assessment of a large power system operating over a wide range of conditions requires an intensive computation for evaluating the system's transient stability against a large number of contingencies. In this study, we investigate the application of multilabel learning for improving training and prediction time, along with the prediction accuracy, of neural networks for online transient stability assessment of power systems. We introduce a new multilabel learning method, which uses a contingenc… Show more

“…In [67], a MapReduce algorithm is used to parallelise the learning of several networks and predict both stability status and the transient stability index. In [68], when the prediction is not credible, time-domain simulations are used to improve the efficiency and in [69], in the context of pre-fault assessment, contingencies are first clustered and then a multi-label neural network is learnt per cluster, to predict the stability status after the occurrence of each contingency in the cluster.…”

“…Static Security Assessment (SSA) considers operating conditions such as overloads, under and over voltages, active and reactive power generation limits, among others using load flow calculation [9,10]. Dynamic Security Assessment (DSA) evaluates the system transient behavior after the occurrence of large disturbances, such as short circuit for example, so that it is of interest to determine if the system can operate maintaining a dynamically acceptable performance (transient stability) [11], and it is simulated considering dynamic time-varying models to represent the EPS, whose solution involves numerical integration algorithms that require great computational effort [12].…”
