Characteristics of electricity generation with intermittent sources depending on the time resolution of the input data

摘要

Data on the electricity supply with intermittent renewable sources are made public by the Transmission System Operators (TSO) and other sources. Data are typically provided in 1 h increments. In this paper, we analyse wind and photo-voltaic data from the Czech Republic. The analysis concentrates on major characteristics of a supply situation where the annual demand is formally met by scaled-up wind and photovoltaic power. The original data are supplied in 1 min increments and successively averaged up to 1 h time resolution. This paper focuses on the dependence of the major supply characteristics on the time resolution of the available electricity data.
