Requirements of the Conventional Energy Supply System for the Integration of a Large Share of Renewable Energy Sources
Abstract
The development of renewable energy sources (RES) motivated by the urgent need to reduce CO2-emissions has been strongly supported during the last years by the German Renewable Energy Act (EEG). To plan the further development of RES, several scenarios were proposed by different institutions. In these scenarios, the impact of RES on the German energy system is usually assessed on the basis of yearly energy production and demand. However, renewable energy sources have a strong impact on the power system due to the weather dependent characteristics of their power production. The influence of a high share of RES on the conventional power plant can thus not be assessed without considering time series analysis.
