Description
In recent years, our star has significantly increased its activity. This has been reflected in a larger number of geomagnetic storms, manifesting in the geomagnetic field perturbation and the formation of strong ground electric fields (GEFs). One of the most important consequences of exceptionally high levels of GEF is the occurrence of geomagnetically induced currents (GICs), which are particularly dangerous for electrical infrastructure and the increasing number of grid failures. One of the interesting events was the May 2024 storm, the most powerful geomagnetic storm in twenty years.
In our study we analaze various parameters related to solar, heliospheric, and geomagnetic activity during the solar cycles 24 and 25, using different machine learning techniques. Moreover, we compute the GEF in the Poland region for these periods using a 1-D layered conductivity Earth model. Based on these parameters, we investigate the anomalies in transmission lines in Poland. Our findings indicate an increase in the anomalies during the appearance of geo-effective events, indicating a potential coupling between them.
