Risk-Constrained Optimal Dynamic Trading Strategies Under Short- and Long-Term Uncertainties IEEE Transactions on Power Systems, 2023 Recent market changes in power systems with high renewable energy penetration highlighted the need for complex profit maximization and hedging strategies against price volatility and generation uncertainty. This work proposes a dynamic model to represent sequential decision making in…
An Integrated Progressive Hedging and Benders Decomposition With Multiple Master Method to Solve the Brazilian Generation Expansion Problem IEEE Transactions on Power Systems, 2022 This paper exploits the decomposition structure of the large-scale hydrothermal generation expansion planning problem with an integrated modified Benders Decomposition and Progressive Hedging approach. We consider detailed and realistic data from…
Reliability-Constrained Power System Expansion Planning: A Stochastic Risk-Averse Optimization Approach IEEE Transactions on Power Systems, 2019 This work presents a methodology to incorporate reliability constraints in the optimal power systems expansion planning problem. Besides Loss Of Load Probability (LOLP) and Expected Power Not Supplied (EPNS), traditionally used in power systems, this work proposes the use…
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…
