THE PROJECT
The aim of HVDC4ISLANDS is to address and improve principal operational and economic aspects of energy islands and, in particular, to introduce the necessary concept of expandability to HVDC/MVDC and hybrid DC/AC systems.
Objective 1
To study viability of different configurations of HVDC and hybrid DC/AC energy islands including their physical location, offshore and onshore connections, availability of renewables and storage resources and multi-vector energy demand management.
Objective 2
To critically evaluate “grid-forming” aspects in multi-terminal HVDC energy islands allowing a seamless transition between operating modes, and provision of grid services at DC/AC interconnections (i.e. synthetic inertia, power oscillation damping, voltage control, “black-start” capability etc.).
Objective 3
To provide stability assessment considerations in order to ensure the intended operation and sufficient interoperability within energy islands and between energy islands and external grids.
Objective 4
To optimise the performance and develop energy management systems for multi-vector, reconfigurable energy islands and reduce their environmental impact. The potential of energy storage, local demand management and additional energy vectors including hydrogen will be considered.
Objective 5
To develop flexible HVDC protection systems for expandable and reconfigurable energy islands taking into account all viable operating scenarios.
Objective 6
To perform a techno-economic-environmental assessment of the proposed solutions for energy islands and to identify mechanisms for their market integration.
