Smoking can kill! Our current energy system is
heavily smoking. In view of critical
CO

emissions and depleting
conventional resources, a transformation towards a sustainable energy system
is needed. Applied Theoretical Physics and the Physics of Complex
Networks are able to contribute to the solution of this grand challenge.
We discuss a simple
network model, which describes a future European electricity system with a high share of wind and solar power generation.
The weather acts as the fluctuating driving force. Weather
data covering multiple years are converted into prospective wind and solar power generation
with good spatial and temporal resolution.
The weather-driven network modelling represents
a direct approach to obtain fundamental estimates on the required backup infrastructure of
highly renewable large-scale energy systems. Estimates on the required amount of conventional backup power plants, transmission lines and storage will be given. Also the optimization of energy system costs is addressed, leading to new design concepts like the
optimal heterogeneity and the benefit of cooperation.
Related to diffusion processes on
networks, flow tracing algorithms are described, which
help to clarify the nodal cost
allocations. More physics-related topics l
ike the storage singularity
and the power flow
renormalization will also be shortly addressed. An outlook about current research on the
coupling of the different energy sectors, the
design of investment roadmaps into the future
as well as the impact of climate change will be given at the end.
