Stochastic inflows and seasonal water value at Manantali
Steeven B. Affognon, Babacar M. Ndiaye, Pierre Mendy +4
Seasonal hydropower operation requires release decisions that account for uncertain future inflows and the opportunity cost of stored water. We assess the Modelling and Optimisatio…
InFlow: entropic stochastic dual dynamic programming with HJB cross-certification for seasonal energy storage
Steeven B. Affognona, Babacar M. Ndiaye, Pierre Mendy +1
Seasonal reservoir operation requires optimization methods that remain reliable under strongly periodic and uncertain inflow dynamics. We present InFlow, a verification-oriented fr…
From Daily Fluctuations to Annual Hydrological Cycles: A Wavelet-Based Analysis of Nonstationary Seasonality in Senegal River Hydropower Inflows
Steeven B. Affognon, Babacar M. Ndiaye, Pierre Mendy +1
This study presents a reproducible framework combining Fourier and wavelet analysis to examine the seasonality of daily inflows at three sites on the Senegal River (Bafing Makana,…
The Wade Formula and the oil price fluctuation: An Optimal Control Theory approach
Pierre Mendy, Babacar M. Ndiaye, Diaraf Seck +1
By considering the Wade Formula, we propose a model to study the evolution of the oil price per barrel. Our model shows that the policy of diversification of the energy is to be su…
