PROJECTS

The project aims to develop an innovative Secondary Substation. Efacec Energia – head of the promoter consortium -, Efacec Electric Mobility, Eneida, University of Coimbra, INESC TEC and ITeCons combine the industry expertise and expectation, and the knowhow and scientific ability that the national scientific and technology system organizations bring to the project, towards creating and applying new scientific knowledge, comprising a demonstrator to be installed at the Low Voltage – LV – distribution grid of EDP Distribuição, the outsourced entity.

MAIN OUTCOMES

• Modular housing granting high thermal, acoustic, physical and mechanical performance, including: sustainable materials; environment sensors and smart management of natural ventilation; urban customization; green roof and façades towards that performance and CO2 capture.
• Solutions towards grid resilience: environment and electric values wireless sensors (energy harvesting, plug and play, inter-changeable/operable).
• A controller providing: modular and distributed architecture; monitoring and remote selfhealing of the LV grid; asset condition monitoring; DER asset and street lighting management; automatic and agnostic smart meters mapping.
• A MV/LV transformer, according to Ecodesign, providing better energy efficiency and lower sound power, using a new partial discharges sensor.
• Less volume MV cells, adapted to the previous sensor and to the new fault detector.
• A device suitable for flexible applications – at the secondary substation and throughout the LV feeder – for: voltage regulation; grid services support, e.g. harmonic distortion mitigation, phase balancing, compensation of voltage dips and of power factor.
• An energy storage system, according to Ecodesign, for: adding dimension to the previous device function; bringing energy efficiency with capacity support during self-healing.

The new solutions will enhance the competitiveness in the domestic and global market.
