A scheduling optimization model for sun tracking of an autonomous heliostat

2013 IEEE Grenoble Conference, 2013
We propose a mathematical formulation for the problem of scheduling the movements of an autonomous heliostat in order to track the sun. We make use of a mixed integer programming model where the main objective is minimizing the total energy consumption.

Methodology for Closed Loop Control of Heliostat Tracking in a Solar Tower Power

Advanced Materials Research, 2011
Due to the inefficient utilization of solar energy in a solar tower power plant, this paper presents a new control method of closed loop tracking. With the current widely-used machine vision technology applied in the heliostats control, it is possible to obtain the deviation of heliostat position by image processing.

Comparison of Two Sun Tracking Methods in the Application of a Heliostat Field

Journal of Solar Energy Engineering, 2004
The basic mathematics and structure of heliostat have remained unchanged for many decades. Following the challenge first made by Ries et al., the non-imaging focusing heliostat recently proposed by Chen et al. provides an alternative in the field of concentrated solar energy.

Latitude-orientated mode of non-imaging focusing heliostat using spinning-elevation tracking method

Solar Energy, 2016
Abstract A comprehensive study of the latitude-orientated configuration of non-imaging focusing heliostat (LO-NIFH) is reported. In this configuration, we have made the sun tracking formulas of a non-imaging focusing heliostat (NIFH) to be independent of the latitude where it is installed; hence we name it a latitude oriented non-imaging focusing ...

Heliostat Dual-Axis Sun Tracking System: A Case Study in KSA

RE&PQJ
This paper demonstrates a case study for solar power tower (SPT) Heliostat, concentrated solar power topology in Dhahran, KSA. A MATLAB code is implemented for the solar position algorithm to calculate the incident angles in order to track the sunbeams during the whole year.
