Hybrid ABC-BAT for Solving Short-Term Hydrothermal Scheduling Problems
Energies, 2019 The main objective of short-term hydrothermal scheduling is the optimal allocation of the hydro and thermal generating units, so that the total cost of thermal plants can be minimized.

Combining hydro-generation and wind energy biddings and operation on electricity spot markets [PDF]
, 2006 Wind generation is growing rapidly in all the world, especially in Europe. The power produced by this kind of generation is difficult to predict and the predictions are not very accurate. In most systems these imbalances are costly.

Inexactness of the Hydro-Thermal Coordination Semidefinite Relaxation
, 2017 Hydro-thermal coordination is the problem of determining the optimal economic dispatch of hydro and thermal power plants over time. The physics of hydroelectricity generation is commonly simplified in the literature to account for its fundamentally ...

Spatially-constrained clustering of ecological networks
, 2014 Spatial ecological networks are widely used to model interactions between georeferenced biological entities (e.g., populations or communities). The analysis of such data often leads to a two-step approach where groups containing similar biological ...
