Optimisation of Aiming Strategies in Solar Tower Power Plants
(AIP, 2018-11-08)
Inclement weather effects have a direct impact on the efficiency of a Solar Power Tower plant and have the potential to damage the receiver by flash heating. An optimised aiming strategy for the heliostat field mitigates ...

Optimisation of aiming strategies in Solar Power Tower plants
(PERGAMON-ELSEVIER SCIENCE LTD, 2017-10-15)
The distribution of temperature on a Solar Power Tower (SPT) plant receiver directly affects the lifespan of the structure and energy generated by the plant. Temperature peaks and uneven distributions can be caused by the ...

Continuous optimisation techniques for optimal aiming strategies in solar power tower plants
(PERGAMON-ELSEVIER SCIENCE LTD, 2019-01-01)
Optimising the aiming strategy is crucial for Solar Power Tower plants, in order to maximise the energy generated, whilst also preventing catastrophic damage to receiver components. In this work, a bi-objective ...

An optimization tool to design the field of a solar power tower plant allowing heliostats of different sizes
(Wiley, 2017)
The design of a Solar Power Tower plant involves the optimization of the heliostat field layout. Fields are usually designed to have all heliostats of identical size. Although the use of a single heliostat size has been ...

Exact controllability to the trajectories for parabolic PDEs with nonlocal nonlinearities
(Springer, 2019-09)
This paper deals with the analysis of the internal control of a parabolic PDE with nonlinear diffusion, nonlocal in space. In our main result, we prove the local exact controllability to the trajectories with distributed ...

A new proof of the existence of suitable weak solutions and other remarks for the Navier-Stokes equations
(Scientific Research Publishing, 2018-04)
We prove that the limits of the semi-discrete and the discrete semi-implicit Euler schemes for the 3D Navier-Stokes equations upplemented with Dirichlet boundary conditions are suitable in the sense of Scheffer. This ...

New results on the Stackelberg-Nash exact control of linear parabolic equations
(Elsevier, 2017-06)
This paper is concerned with Stackelberg-Nash strategies to control parabolic equations. We have one control, the leader, that is responsible for a null controllability property; additionally, we have a couple of controls, ...

Heliostat field cleaning scheduling for Solar Power Tower plants: a heuristic approach
(Elsevier, 2019-02-01)
Soiling of heliostat surfaces due to local climate has a direct impact on their optical efficiency and therefore a direct impact on the productivity of the Solar Power Tower plant. Cleaning techniques applied are dependent ...
