IMPACTS OF LARGE-SCALE INTERMITTENT RENEWABLE ELECTRICITY - HOW TO INTEGRATE THESE INTO THE ENERGY SYSTEM WITH A MARKET-DRIVEN APPROACH?

摘要

A shift towards low-carbon electricity generation is prevalent in OECD countries. Particularly the intermittent renewable energy sources of wind and photovoltaics form the main pillars of future electricity generation. This unpredictable renewable infeed comes along with distinctive challenges for technical and market integration. This is especially valid for countries with strong wind and photovoltaic capacity development e.g. Germany, Denmark and China. A key issue is to find reasonable use for excess intermittent renewable electricity generation and avoid curtailment of renewables with close to zero short-term marginal costs.
