Title: Managing massive wind integration in islands
Affiliation: SEV


In the Faroe Islands, a non-interconnected grid with limited sources of inertia and where wind generation can represent more than 50% of the online generation in low load periods, the variable nature of wind naturally induces grid stability issues and leads to about 20% of wind curtailment. In order to overcome short term variations, lasting from seconds to minutes, the local utility SEV has deployed a 2,3 MW ESS installation at the site. The presentation describes the high ambitions in the Faroe Islands reaching a 100% renewable electricity generation in 2030, the available resources in the islands and the technical solution and results of combining a 2,3MW Li-ion ESS with a 12 MW wind farm. The battery system, operational since 2016, provides ramp rate control of the wind farm and frequency regulation to the island grid, enabling maximum use of the wind resource and displacement of otherwise necessary diesel generation.
