Demonstrations of DC Microgrid and Virtual Power Plant Technologies on the Danish Island of Bornholm

The paper presents the scope and research activities, both analytical and experimental, to be carried out on the Danish Island of Bornholm under the 4-year (2019-2023) H2020 Insulae project. The two use cases taking place in Denmark are described. The first use case is dedicated to modelling and testing a low-voltage DC microgrid comprising a battery storage, renewable energy sources, and an EV fast charger, towards providing grid services. The second use case investigates the potential of a renewable-driven virtual power plant embracing different energy domains (electrical, heat, gas, transportation) for flexibility provision to the islanded energy system. Planned research activities for both use cases are described along with results in terms of design and engineering.
