Transmission network loading in Europe with high shares of renewables

摘要: The need for long-distance power transfers in the electricity system is being driven by both deeper market integration and increasing share of renewables generation. best resources are often located far from load centres, while variable renewables, such as wind solar, benefit smoothing effects when aggregated over large areas. However, increased usage transmission infrastructure raises question how associated costs should be distributed. authors present here application an existing algorithm called marginal participation (MP) which can used to allocate flowing through each network asset (lines transformers) particular users. They consider two new methods extend MP high voltage direct current lines that operate parallel alternating networks. then apply allocation a future scenario with penetration Europe 2050, developed part Smooth PV project. see significant increase usage, including rise proportion cross-border flows. disproportionately offshore wind, because its geographical concentration away centres.
