Project consortium


DC grids have become attractive in recent years due to the high proliferation of renewable energy sources together with the increase in DC loads. The TIGON project demonstrates hybrid microgrid innovations with the aim of enhancing the reliability and resilience of decentralised renewables-based power systems.



  • Sets out a path to the hybrid AC/DC grid transition
  • Develops new generation of broadband semiconductor-based power electronic devices, such as the introduction of solid-state transformers (SST) module to provide an interconnection between MV, AC and DC distribution grids
  • Increases share of RES in the power network and resilience to faults and cyber attacks


About the practice

DC grids can help energy efficiency and control of power quality. They can also better cater for renewables and energy storage. However, the lack of DC microgrids hinders these objectives and they need to be enhanced for future smart grids and turned into commercially viable technology.

TIGON proposes a four-level approach for improving reliability, resilience, performance and cost-efficiency of hybrid grids. This involves pioneering power electronic solutions and software systems and tools focused on the efficient monitoring, control and management of DC grids. Two hybrid microgrids are being designed and set up in France and Spain and two ‘use cases’ (a public metro network in Sofia, Bulgaria and a residential district in Finland) will demonstrate solutions.

TIGON is an EU-funded project under the HORIZON 2020 framework implemented by consortium of 15 partners and coordinated by Fundación CIRCE.
