“…This scheme is typical in solar plants with distributed collectors [22]. This static FF is designed supposing that outlet solar field temperature (T2) may be modeled by considering the behavior of a hypothetical equivalent absorber tube with the same behavior as the whole solar field [25]: (1) Where:…”

“…A control system has been developed to optimize distillate production under variable operating conditions. Feedforward controllers (FF) following the ideas in [22][23][24][25] were implemented. This paper is focused on the study and implementation of a control architecture for an experimental SMD facility in order to improve the system operation and reduce the use of nonrenewable energy.…”

Abstract-This paper presents a preliminary architecture for controlling solar membrane distillation facilities. Membrane distillation (MD) is a desalination technology under investigation, without industrial applications and with only few pilot systems. There is a general lack of information on how these systems perform during real solar-powered operation and how distillate quality deteriorates under intermittent conditions. One of the few systems that have been fully described in literature is the MD-solar pilot plant in Plataforma Solar de Almería (PSA), Spain. This paper presents a first step towards an optimal automatic operation of this system through the definition of operation modes and basic control loops. A discussion of control schemes to be implemented in the near future is also included in this work.

Adaptive Control of Solar Energy Collector Systems

View full text Add to dashboard Cite

This chapter provides a broad overview of solar thermal energy systems. The aim is to describe the context of distributed collector solar fields used in plants that apply parabolic trough technology. Furthermore, the temperature control problem associated to distributed collector solar fields is explained and the use of adaptive control to solve it is motivated. In contrast to subsequent chapters that use mathematics to explain control algorithms and the models upon which they rely, the approach in this chapter resorts to qualitative explanations together with some plant data to introduce the main ideas.

Abstract:The water deficit in the Mediterranean area is a known matter severely affecting agriculture. One way to avoid the aquifers' exploitation is to supply water to crops by using thermal desalination processes. Moreover, in order to guarantee long-term sustainability, the required thermal energy for the desalination process can be provided by solar energy. This paper shows simulations for a case study in which a solar multi-effect distillation plant produces water for irrigation purposes. Detailed models of the involved systems are the base of a predictive controller to operate the desalination plant and fulfil the water demanded by the crops.
