<p>With an increased share of solar and wind energy e.g. in the German and
European energy systems it is becoming increasingly important to analyze the
impact of weather variability on the reliability of the energy production.
In this study, we calculate solar PV and wind power capacity factors using
two recently developed climatological datasets that provide information with
high spatial and temporal details on the continental (European) scale and
are of sufficient length for assessments at climatological time scales:
Surface radiation derived from meteorological satellites (SARAH-2) and wind
speed from a high-resolution regional reanalysis (COSMO-REA6). Balancing
effects are analysed: On average, the seasonal cycles of PV and wind power
production complement each other in Germany as well as in Europe. The
frequency of events with a risk of low electricity generation is analyzed
under different assumptions. When using wind energy over German land areas
as a reference case, the results illustrate that the number of low
production events is reduced when Germany's Exclusive Economic Zone is
included into the analysis, or when a combined system of PV and wind energy
is considered. A European-wide analysis also leads to a distinct reduction
of such events.</p> |
