Flexibility Needed IEEE Power and Energy Magazine, 2017 In modern power systems, WE are transitioning to an increasing penetration of massive low-cost wind and solar generation, which will require indispensable system flexibility for balancing requirements to maintain system performance. The existing actors have limited technical capabilities to provide the needed flexibility, and new alternatives are…
Managing Uncertainty in Implementation Times of Competitively-Procured Transmission via Risk-Sharing and Winner Selection Functions IEEE Transactions on Power Systems, 2017 We develop a MILP framework to design risk-sharing and winner-selection mechanisms, applying a principal-agent approach to competitive bidding processes to select transmission agents, with attention to cases where uncertainties in implementation times of transmission facilities…
Combinatorial and Simultaneous Descending Auctions for Electricity Transmission Concessions IEEE Transactions on Power Systems, 2017 Many countries use auctions to select agents to which transmission concessions are awarded. Where multiple concessions are auctioned each year, there are potential benefits, for transcos and grid users, in using auction protocols allowing risk-averse bidders to explicitly consider complementary…
Sustainable and Economic Alternative for the Electric Supply of Isolated Communities in the Brazilian Off-Grid Systems Journal of Power and Energy Engineering, 2017 Roughly 99% of the demand for electricity in Brazil is supplied by a national interconnected grid. The remaining 1% is spread in several “isolated systems” of the Amazon region—mini-grids that rely on…
The Paraíba do Sul River basin – The Paraíba do Sul River basin OECD Studies on Water, 2017 The Paraíba do Sul River basin represents an interesting case-study on the implementation of water charges in Brazil for two primary reasons: i) it was the first interstate basin in the country to implement water charges, helping…
