About the Project

The project aims to research and develop a new range of conversion solutions for large power photovoltaic power plants (> 50 MW), incorporating in a single conversion platform, the various aspects of the conversion circuit and integration into the grid, namely: inverter, transformer, medium voltage (MV) switchgear, sensing and distributed digital control platforms, ensuring distribution and operational coordination, with a view to maximizing their potential. The scope of study, research and development proposed here will naturally focus on all the aspects mentioned above, through the search for new solutions for the development of power modules, transformers and digital and algorithmic control platforms, up to the design of the self-supporting platform.

The broad spectrum of competences that the development of the solution proposed here implies is evident in the framework of partners that make up the active team allocated to this project. Efacec Energia – leader of the promoting consortium, University of Minho and Itecons combine the experience and expectations of the industry, as well as the “know-how” and scientific and technical capacity that characterize the SCTN entities. Given the project’s application scope, it is equally important to contribute to the operational needs and gains in a real exploration environment, a contribution that will undoubtedly be promoted by the partner Efacec Engenharia, which will actively contribute in the specification phase and in the promotion of an installation for the proof-of-concept and demonstration phase.

The proposal present in the Megasolar project fits precisely in this technological aspect, seeking to contribute to the global objectives stated above, based on the following pillars:

  • Efficiency – increasing efficiency is a key point and objectives will be established for each of the subsystems present in the project, whether in normal operation, in reducing the consumption of auxiliaries, and also in reducing consumption in standby mode;
  • Competitiveness – the photovoltaic solar market is quite competitive, so solutions will be sought that enhance the €/kW ratio, in various perspectives: increased power, reduced cost of the solution, or increased range of operating characteristics that have impact on the scale of the plant, or on the integrated design of the solution, focusing on the impact in terms of reducing installation costs;
  • Scope of solutions – the availability of technical solutions capable of being installed in diverse and extreme operating scenarios, in environmental terms, or others, must be addressed, together with the characteristics that allow transport;
  • Flexibility – flexibility in terms of application, both in terms of adaptation and configuration, which is decisive in interfaces with other systems, especially with regard to the interface with the electrical network;
  • Digitization – increased capacity for data acquisition, information processing and autonomous recognition of the operating status, promoting the platform for the execution of advanced operating control methodologies, optimized and integrated asset management, self-diagnosis and maintenance assistance;
  • Sustainability – development of equipment with an emphasis on the theme of ecodesign, using more sustainable materials and, whenever possible, recycled and/or recyclable, in order to reduce, across the global solution, its environmental impact.
