Hierarchical set-point optimization and feedforward strategy for collector defocusing of a solar plant
(Springer, 2021)
One of the main control objectives in parabolic trough solar thermal plants is to maintain the outlet temperature around an operating point. For this, a synthetic oil flow is used as the main control variable. However, ...

A deep learning-based strategy for fault detection and isolation in parabolic-trough collectors
(Elsevier, 2022-03)
Solar plants are exposed to the appearance of faults in some of their components, as they are vulnerable to the action of external agents (wind, rain, dust, birds …) and internal defects. However, it is necessary to ensure ...

Thermal balance of large scale parabolic trough plants: A case study
(Elsevier, 2019)
The main control objective in commercial solar parabolic plants is to track the average temperature of all the loops around a reference set by the operator, by manipulating the flow of a synthetic oil. Due to the large ...
