摘要: For the large-scale integration of electricity from renewable energy sources (RES-E), German system seems to reach its limits. In 2009, wholesale market experienced serious negative prices at times high wind and low demand. The feed-in in Germany consists a fixed price, take-off obligation RES priority rule, practice only very restrictive use RES-E curtailment. Exactly latter is problem. We argue that overall performance would improve seriously by lifting restrictions on voluntary curtailment agreements, while retaining rule as such. Since generators can under this reform, investment conditions improve, leading higher installed capacity. This turn implies reduced output due actually be offset all periods which there no
