February 12 (Renewables Now) - Brazilian state-owned energy research firm EPE together with the National Electric System Operator (ONS) and German development agency GIZ have started a project to study how to better integrate intermittent renewable energy sources into the country's grid.
The project is part of the "Future Energy Systems: Integrating sources of intermittent renewable energy in the Brazilian energy mix" programme. In all, the study will focus on how the country's grid needs to be prepared - in terms of operation and expansion - to support the increased penetration of renewable energies with variable generation throughout the day, such as wind and solar power plants, as well as the combination of the said sources with energy storage systems. The technological solutions available to mitigate any potential negative impact of the increased green energy share in the National Interconnected System will also be evaluated.
Lahmeyer International has been contracted, after a competitive selection process, to carry out the study, EPE noted. It has up to 14 months to do so.
