Evaluation of Solar and Lunar Eclipse Impacts on Danish Power System as a Case Study

Power systems stability and reliability are two critical issues that are considered in designing and operational states of the power systems. In addition to the technical failures that can affect the appropriate performance of the power systems, there are several environmental menaces, namely, storms, earthquakes, freezing weather, animal-caused outages, etc. In this paper, the effect of solar and lunar eclipses on the Danish power system has been investigated among the other environmental threats. The power system of Denmark, due to the high penetration of renewable energy sources, is contemplated as a case study. The reports and data depict that despite the often occurrence of an eclipse, these astronomical events' impacts should have been taken more into consideration to maintain stability and improve the reliability of the power system.
