Power transmission in a renewable European future — •Sarah Becker1, Rolando Rodriguez2, Martin Greiner2, and Stefan Schramm1 — 1FIAS Uni Frankfurt, Germany — 2Uni Aarhus, Denmark
We investigate a renewable-based European electricity system, where wind and solar PV produce as much energy as is consumed. Since this generation flucuates with the weather, there will in general be a mismatch between load and generation in individual hours. We assume deficits to be covered by dispatchable power plants, while excesses are curtailed.
In this setting, we study different flow paradigms for inter-country power transmission, i.e. ways to share renewables and match deficits and excesses between the countries. Particular focus is placed on the effects on backup energy usage ("how much fuel is burned?"), backup capacity needs ("how many dispatchable plants need to be available?"), and transmission line investments. Furthermore, we examine different approaches to transmission grid strengthening and compare actual and optimized developments.
