Impact of Photovoltaics on Frequency Stability of Power System During Solar Eclipse

摘要

This paper analyses the influence of variable production of photovoltaic plants on the synchronous continental Europe interconnection during the solar eclipse of March 20, 2015. For countries with a high share of photovoltaics, the daily photovoltaics generation is estimated for the worst-case scenario - a clear sunny day. The presented results of long-term dynamic simulations focus on frequency stability (taking into account daily load diagram, secondary and primary frequency control, system inertia, settings of frequency protections and load frequency shedding).
