Multistage stochastic programming model and solution algorithm for the capacity expansion of railway network

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
We consider a capacity expansion problem for a railway network under uncertainty. In our approach, integer and stochastic programming provide a basic framework.

Medium-Term Hydropower Scheduling with Variable Head under Inflow, Energyand Reserve Capacity Price Uncertainty

open access: yesEnergies, 2019
We propose a model for medium-term hydropower scheduling (MTHS) with variable head and uncertainty in inflow, reserve capacity, and energy price. With an increase of intermittent energy sources in the generation mix, it is expected that a flexible ...
