    Opis:
    The subject of the work is an analysis of two types of solar collectors: flat-plate and evacuated tube collectors in the same, natural working conditions during the period from 1st May 2017 to 30th September 2017. The scope of work includes a descriptive presentation of a measuring setup, located on the roof of the building of the Construction University of Warmia and Mazury in Olsztyn, and also the research methodology, as well as an analysis of the results and conclusions obtained. The measurements allow a comparison of the efficiency of the flat-plate and evacuated tube collectors by calculating heat yields, based on the following variants: average hourly irradiation, outdoor air temperature, temperature of the medium supplying the collectors and temperature of the returning medium. An analysis of the heat yield was made in relations to the individual absorber surface, to determine which of the tested collectors showed higher efficiency under real operating conditions during the spring-summer period.

    Opis:
    By the emergence of distributed energy resources, with their associated communication and control complexities, there is a need for an efficient platform that can digest all the incoming data and ensure the reliable operation of the power system, which can be achieved by using digital twins. The paper discusses the advantages of using digital twins in the development of control systems and operation of distributed heat and electric power generation facilities. The possibilities of using the digital doubles for increasing the efficiency of the considered objects is presented as the example of optimizing the configuration of a control system of solar collectors in the presence of heat losses in pipelines of the external circuit. Further, the total balance consumed and generated electric and heat energy are presented. Examples of algorithms for protecting equipment to improve security are given, and the possibilities of improving the reliability of distributed power systems are considered. The system use of the digital twins provides the possibility of developing and debugging control algorithms, which increase the efficiency, reliability and safety of control objects, including distributed thermal and electrical power generation complexes.

    Opis:
    Solar energy is the most affordable source of energy. Parabolic trough systems are used to concentrate and extract heat, therefore it’s very significant to analyse its performance in terms of energy and exergy. Exergy based analysis of the system ensures the eradication of losses, resulting in the yield of energy of the highest quality. In this paper, an investigation has been carried out using numerical simulation with an objective of analysis of Parabolic Trough Collectors on the basis of energy and exergy. Detailed second law analysis has been performed by varying the system and operating parameters through computer simulation. Exergy output has been determined by analysing the effect of major system parameters, namely, mirror reflectivity, glass transmissivity, absorptivity, the diameter of glass envelop, and the receiver. The operating parameters considered in the investigation are insolation and temperature rise parameters. The extensive investigation of the parabolic trough of a concentrated solar power plant for various design parameters in the range of operating parameters reveals that it is beneficial to operate the system at higher temperature as opposed to the preference of the operating system at lower temperature from purely thermal considerations.
