ABOUT HYNET

The interest in direct current (DC) power transmission and distribution (T&D) systems has surged in both academia and industry, driven by the growing use of power electronic-based loads and the increasing deployment of distributed energy resources (DERs), many of which operate in DC or include a DC stage. fIn response to the ongoing crisis in Ukraine, the European Commission (EC) introduced the REPowerEU Plan, which aims to reduce Europe’s reliance on Russian energy imports by increasing renewable energy generation capacity to 1236 GW by 2030 a significant boost from the originally projected 1067 GW under the “Fit for 55” package. Achieving this ambitious target will require contributions from various sectors, with DC technologies playing a key role in the energy transition.

While substantial progress has been made in increasing electricity generation from renewable energy sources (RES) in several EU member states, further efforts are necessary to achieve a fully carbon-neutral power system. A key component of this transition is the widespread adoption of offshore wind energy, which is favored for its higher availability rates and public acceptance.

HYNET PROJECT IS DESIGNED TO

  • Establish standardized methodologies and ensure interoperability for multi-terminal, multi-vendor MVDC and LVDC systems.

  • Develop innovative technologies for the transnational design and planning of AC/DC hybrid power systems.

  • Define and validate functional requirements for AC and DC grid-forming capabilities.
  • Design, implement, and demonstrate a comprehensive suite of solutions that promote the adoption of DC power systems across all voltage levels, while evaluating the techno-economic advantages of DC versus AC systems.

  • Demonstrate these innovations in four European countries, showcasing the potential of AC/DC hybrid grids in both existing and planned infrastructures.

PARTNERS

HYNET consists of 16 partners from 9 countries across Europe, combining competences and resources from academy/research community, as well as key grid stakeholders, to form a well-balanced and multidisciplinary consortium contributing, each in their area of expertise, to the success of the project goals.
