Role of electricity grids in energy transitions Allan Dahl Andersen

Drivers: RES geographically dispersed, often far from consumption (offshore wind) Two-way traffic on grid Electricity production increasingly distributed and local Non-dispatchable RES  need for flexibility Energy integration in EU Result in two broad trends of grid transformation

The grid is exposed to different forms of new transformation pressures: Distributed RES generation which is placed in new geographical areas Number of generators rises from 10.000s to millions while on average decreasing in scale There is a 2-way flow of power rather than 1-way flow Larger shares of non-dispatchable RES which creates supply-side fluctuations Electrification of energy use (transport and heating) leading to new patterns of demand-side fluctuations How are DSOs (distribution system operators) coping with the new technological challenges and increasing system complexity?

What are the main institutional and technological challenges in «transnational energy integration» (by coupling electricity grids together)? The Kriegers Flak project illustrates several challenges that are important for Europe’s possibilities for creating a pan-European supergrid. The transmission way forward
