Abstrakt

A Danish island, Aero, has wind power more than it needs, but still has to import power from the mainland due to the balance issue of the island. In addition, Aero has just set up an e-ferry to facilitate transportation between the island and the mainland over a 20 km distance. This paper will study the minimum storage that will be needed to support the balance of its 100% renewable-based energy system, i.e., reduce the power import from the mainland to zero. The analysis will include different storage technologies with different efficiencies, such as Lithium-ion battery (close to 100% round-trip efficiency) and high-temperature thermal storage (about 41% round-trip efficiency) since they require different optimization models. The results show that for the case with a low round-trip efficiency, more wind power will be required in order to be 100% self-sufficient. In addition, as the self-sufficiency (the percentage of the total energy consumption that is supplied by the island itself) goes up, the required size of the storage goes up even quicker.
