Estado del arte de despacho económico hidro-térmico-eólico utilizando técnicas heurísticas

Hydrothermal planning has been seen as an optimization problem, where the aim is to minimize the fuel cost of thermoelectric power plants by searching the optimal dispatch scheme. The economic operation of power plants, thermal and hydro electrical units has been performed by deterministic methodologies, which the majority of times are extremely complicated to implement on large power systems. Set in this context, heuristic techniques have been implemented to solve the optimization problem in a simpler mathematical formulation including non-conventional renewable energy sources such as wind energy. The present analysis provides a comparative review based on the results obtained in different relevant articles that provide a satisfactory solution to the hydrothermal problem based on heuristic techniques for standard test systems.
