Predicting power outages caused by extratropical storms [PDF]
Natural Hazards and Earth System Sciences, 2021 Strong winds induced by extratropical storms cause a large number of power outages, especially in highly forested countries such as Finland. Thus, predicting the impact of the storms is one of the key challenges for power grid operators.

Power allocation for estimation outage minimization with secrecy outage constraints [PDF]
2016 Australian Communications Theory Workshop (AusCTW), 2016 In this paper, we investigate the distortion outage minimization problem for a wireless sensor network (WSN) in the presence of an eavesdropper. The observation signals transmitted from the sensors to the fusion center (FC) are over-heard by the eavesdropper.

Outage Estimation in Electric Power Distribution Systems Using a Neural Network Ensemble
Energies, 2021 Outages in an overhead power distribution system are caused by multiple environmental factors, such as weather, trees, and animal activity. Since they form a major portion of the outages, the ability to accurately estimate these outages is a significant ...

Power Outage Fault Judgment Method Based on Power Outage Big Data
EAI Endorsed Transactions on Energy Web, 2023 INTRODUCTION: With the deepening of the application of big data technology, the power sector attaches great importance to power outage judgment. However, many factors affect the judgment result of power outage, and the analysis process is very complicated, which can not achieve the corresponding accuracy.

Load dependence of power outage statistics [PDF]
EPL (Europhysics Letters), 2019 The size distributions of power outages are shown to depend on the stress, or the proximity of the load of an electrical grid to complete breakdown. Using the data for the U.S. between 2002-2017, we show that the outage statistics are dependent on the usage levels during different hours of the day and months of the year.
