Numerical models for electricity markets are frequently used to inform and support decisions. How robust are the results? Three research groups used the same, realistic data set for generators, demand and transmission network as input for their numerical models. The results coincide when...

The electricity systems have a central role to play in the transition towards a low carbon economy and integration of renewable energy sources in the European Union. However, the European electricity networks face a diverse set of existing and new risks that can hamper the energy security of...

Connections between individuals facilitate the exchange of goods, resources and information and create benefits. These connections may be exploited by adversaries to spread their attacks as well.
