“…The condensate produced in the PCS is treated and returned to the steam generator. The set of SCF, storage tanks, and PCS systems are called Distributed Collector Systems (DCSs) [22,23]. Next, the SCF and PCS models will be described with their basic principles and foundations, such as the energy balance.…”

The increase of renewable energy generation to change the productivity of a country and electrify isolated sectors are some of the priorities that several governments have imposed in the medium term. Research centers are looking for new technologies to optimize the use of renewable energies and incorporate them into hybrid generation systems. In the present work, the modeling of a solar thermal energy generation plant is being carried out. The climatic data used belong to two coastal cities and one island of Ecuador. The contribution of this work is to simulate a complete model of SCF and PCS, in which the variables of outlet temperature and oil flow are involved at the same time. Previously investigations use only outlet temperature for evaluating power plants. The model of the solar thermal plant is composed of a field of solar collectors, a storage tank, and an energy conversion system. As a result, we obtain a model of a thermosolar plant that will allow us to make decisions when considering the incorporation of micronetworks in systems isolated from the electrical network. The use of thermosolar technology allows the reduction in the risk of spills by the transport of fossil fuels in ships. The study of the CO2 emission factor in Ecuador from 2011 to 2018 is also carried out.

“…The net load ramp rate of PT with TES, which operates as a peaking plant, must vary rapidly in a high renewable electricity scenario [8,13]. The dynamic characteristics concern to the operation safety of PT need to be investigated, including the dynamic performances of PT receiver, steam generator, thermal storage system, and steam turbine [14][15][16]. To better understand the dynamic performances of the steam generator in PT, which act as a peaking plant in the multi-energy integration system to carry out peak-valley regulation, will be especially significant.…”

Concentrated solar power plant (CSP) with thermal energy storage can be operated as peak load shaving plant, which is one of the most economic solutions to the intermittency of renewable energy grid. The steam generation system (SGS) is the central hub between the heat transfer fluid and the working fluid of CSP, of which the dynamic characteristics need to be further investigated. The SGS of Solar Two power tower plant with the molten salt as both the heat transfer fluid and storage media is selected as the object. The mathematical model with lumped parameter method is developed to analyze its dynamic characteristics. Model validation is carried out and it shows that the proposed model can simulate the characteristics of SGS in an accurate manner. Five simulation tests were carried out under the disturbances that the molten salt solar tower power plant may encounter under various solar irradiation and output electrical load. Both the dynamic and static

“…The thermo-solar plant combined 5960 m 2 flat-plate collectors with 4039 m 2 of parabolic collectors. Ampuño et al [13] proposed a dynamic model for the control and simulation of a solar network located in Almeria, Spain, to supply the thermal duty of a multi-effect desalination unit. The solar plant consisted of 60 flat-plate collectors with five parallel lines.…”

Incorporating the Concept of Flexible Operation in the Design of Solar Collector Fields for Industrial Applications

This work introduces the concept of flexible operation in the design of solar thermal utility systems for low temperature processes. The design objectives are: (a) The supply of the thermal needs of the process (heat duty and minimum required temperature), and (b) the maximization of the operating time during the day. The approach shows how the network structure is defined by adjusting the mass flow rate and the inlet temperature of the working fluid to achieve the smallest collector surface area. This work emphasizes the need to specify the solar network structure, which is comprised of two main elements: The number of lines in parallel and the number of collectors in series in each line. The former of these two design specifications is related to the heat load that the system will supply, while the latter is directly related to the delivery temperature. A stepwise design approach is demonstrated using two case studies where it is shown that the detailed design of the solar collector network structure is fundamental for a successful thermal integration with minimum investment. In this paper, the design methodology is based on flat-plate solar collectors, but it can be extended to any other type of low temperature solar technology.
