<p>Este articulo trata sobre el estudio de viabilidad económica de una central termosolar cilíndrico-parabólica de 50 MW en el término municipal de Badajoz. Para ver las diferentes alternativas en el diseño y estudio económico de la instalación se han tenido en cuenta dos casos, un primer caso de la central sin almacenamiento térmico y un segundo caso de la central con almacenamiento térmico. La finalidad con la que se presenta este estudio es analizar los diferentes casos y presentar conclusiones al respecto.</p><p>The aim of this study is to do an economic feasibility study in a cylindrical-parabolic solar thermal plant of 50 MW in Badajoz. Two different cases have been studied, first case the solar thermal plant without thermal storage and the other case, the solar thermal plant with thermal storage (salt tanks). The advantages and disadvantages of the use of each element have also been analyzed.</p>

Research on efficient and economical thermal storage technology becomes common issue to the scholars. Especially research on PCMs becomes hot spot these years. In view of the discontinuity and instability of solar energy, efficient and economic research on energy storage technology occupies a very important position. This article summarizes and evaluates the research development and applications of solar thermal storage technology with PCMs both in China and the other countries. Including four parts: A review on preparation of new composite phase change materials and its thermophysical properties was carried out. Various heat transfer enhancement technology was overviewed. Including adding metal fill, adding graphite, capsule package, plus fins, adding carbon fiber and composite phase change materials, etc. Mathematical modeling of a latent heat thermal energy storage system (LHTES) was reviewed in recent years which is used for the optimum material selection and to assist in the optimal designing of the systems. The important characteristics of different models and their assumptions used are presented and discussed, the experimental validation of some models are also presented. The applications and prospects of PCMs used in the different fields were summarized, such as industry, agriculture, construction, textiles, electronic products, medicine, transportation etc. Finally, conclusions and perspectives were drawed. Hope to provide references to the other researchers in this field.

Levelized Cost Of Electricity

Due to climate change and the need to decrease the carbon footprint of urban areas, there is an increasing pressure to integrate renewable energy and other components in urban energy systems. Most of the models or available tools do not provide both an economic and environmental assessment of the energy systems and thus lead to the design of systems that are sub-optimal. A flexible and modular simulation tool, Eco-Sim, is thus developed in the current study to conduct a comprehensive techno-economic and environmental assessment of a distributed energy system considering different configuration scenarios. Subsequently, an intermodel comparison is conducted with the Hybrid Optimization Model for Electric Renewable (HOMER) Pro as well as with a state-of-the-art industrial tool. Eco-Sim is then extended by including the heating demand, thermal conversion (by using heat pumps and solar thermal) methods and thermal storage. A parametric analysis is conducted by considering different capacities of solar photovoltaics (PV), solar thermal panels and energy storage technologies. The levelized cost of electricity, the autonomy level and the CO 2 emissions are used as the key performance indicators. Based on the analysis of a study case conducted in a neighbourhood in Geneva, Switzerland, the study reveals that, with the present market prices for batteries and seasonal changes in solar energy potential, the combination of solar PV with battery storage doesn’t bring a significant autonomy to the system and increases the CO 2 emissions of the system. However, the integration of thermal storage and solar thermal generation is shown to considerably increase the autonomy of the neighbourhood. Finally, multiple scenarios are also run in order to evaluate the sensitivity of economic parameters on the performance indicators of the system. Under the assumptions of the model, to foster investments in solar PV and battery installations, falling installation costs or stronger policies in favor of renewable energy seem necessary for the future.

The One

The main methods (pressing and winding) of the processing of hybrid polymer composites to obtain items were examined. Advantages and disadvantages of the methods were noted. Good combinations of different-module fibers (carbon, glass, boron, organic) in hybrid polymer materials are described, which allow one to prepare materials with high compression strength on the one hand, and to increase fracture energy of samples and impact toughness on the other hand.

First Case

Coordinative constructions are traditionally opposed to subordinative constructions. However, this opposition comes down to denial of dependence in coordinative constructions. Thereby the parity of these two constructions does not come to light: subordinative construction can be described without coordinative one. This situation is not improved by detection of a coordinative triangle in all coordinative constructions. The article shows a new approach in the study of coordinative constructions: a coordinative construction is a system; there are not only specific relations – a coordinative triangle, – but also specific elements. Novelty of the study consists in the address to extralinguistic facts, viz. a mathematical concept of a set and its elements. There are a lot of similarities between them. A set in mathematics includes generalizing elements and the composed row in coordinative constructions; in the first case the set is not partitioned, in the second case it is partitioned. In mathematics equivalent components in coordinative constructions correspond to the set elements. A characteristic property in mathematics is homogeneity in coordinative constructions and etc. It is firstly demonstrated, that coordinative and subordinative constructions are correlative and the study of one construction is impossible without the study of the other one. Their parity is shown in coordinative constructions with elements of one set, in subordinative ones with elements of different sets. Cf.: roses and tulips –red roses. In the coordinatiму construction elements of one set are called: «flowers »; in the subordinative construction there are elements of different sets: «flowers » and «colors». It should be noted that the mathematical concept of a set relates to so called logical aspect in linguistics or thinking about reality.
