Transmission grid extensions for the integration of variable renewable energies in Europe: Who benefits where?

摘要: Abstract Variable renewable energy (VRE) generation from wind and sun is growing quickly in Europe. Already today, VRE's power contribution at times close to the total demand some regions with severe consequences for remainder of system. Grid extensions are necessary physical integration VRE, i.e., transports, but they also have important economic all system participants. We employ a regional, model examine role grid market effects VRE derive cost-optimal macroscopic transmission projected solar capacities Europe 2020 characterize their on high regional technological resolution. Without extensions, lower electricity prices, new price dynamics reduced full load hours conventional technologies result proximity capacities. This leads substantial changes achievable revenues utilities. partially alleviate redistribute these effects, mainly benefit baseload themselves.
