EPE and the Brazilian Ministry of Mines and Energy (MME), in partnership with the German Ministry of Economy and Energy (BMWi), with the support of the German Agency for International.
Cooperation (GIZ) organized the Workshop "Untapping flexibility in power systems", with the objective of discussing strategies to promote operational flexibility in its electrical systems, especially to cope with the growth of variable renewable resources, notably wind energy and solar photovoltaic. The event was held in Rio de Janeiro, on October 6th, 2017, on the premises of EPE, with presentations and debates with experts from Brazil and Europe.
Opening speeches were delivered by Mr. Luiz Augusto Barroso (CEO of EPE), Mr. Carlos Alexandre Pires (Director at the MME) and Mr. Ralf Christmann (Deputy Head of the Renewables Division at BMWi). Attendees included experts from relevant institutions in the Brazilian power sector, such as EPE, CCEE, CEPEL and ONS, and also Christian Segnitz, a representative of the German Embassy.
The presentations started with a comprehensive overview of both the Brazilian and German power systems and the main drivers for the growing needs for operating flexibility in face of renewable penetration. A presentation on the innovative concept of "Virtual Power Plant", which makes use of technology to aggregate distributed resources and offer valuable services to the system (including demand-side management), in a competitive environment, closed the morning session. In the afternoon, presentations explored the "Flexibility Tracker", a scoring system that can work as a tool for assessing how certain systems stand regarding to flexibility, and the potential adjustments to market signals and regulatory arrangements. Both morning and afternoon sessions were followed by debates.
As a result, EPE and the BMWi have published a document, available at the link below, with a summary of the presentations and debates, as well as the main findings of the workshop.
