Publication Category: Conference Papers Publication year: 2011 Activity Type: Hardware / Software Research Area: Super Grids

The European power transmission grid is on the critical path to meet the European Union (EU)’s climate change and energy policy objectives for 2020. This trend is expected to continue also for the years after 2020, in view of ambitious decarbonisation targets by 2050. The main challenge will be the power system integration of very large amounts of variable renewable energy sources (RES), especially wind and also solar, while keeping overall system reliability at acceptable levels, in a liberalised background. To this scope, a more flexible, yet robust, transmission grid is needed.

G. Celli, S. Mocci, F. Pilo, S. Tedde, G. Fulli, A. Purvins, E. Tzimas
Publication Category: Conference Papers Publication year: 2011 Activity Type: Software Research Area: Smart grids interfaces with Super Grids

In the last decades an increasing integration of renewable energy sources (RES) in the extra high voltage (EHV) and high voltage (HV) networks, boosted by technical reasons and political decisions has been noticed. RES introduce significant environmental benefits, but also considerable difficulties to power system planning and operation. In fact, if RES are correctly allocated, they allow deferring network upgrade investments and decreasing Joule losses.
