This book was released on 1991-04-30 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to facilitate detailed solar system simulations and to make such simulations readily available to solar engineers in their daily practice of system dimensioning and performance calculations, user friendly software for personal computers has been developed as a system specific simulation program for a frequently installed group of water based solar system types. The program package has been developed as part of the OPSYS R&D-program of the Commission of the European Communities and has been named EURSOL. The set of system configurations considered includes different types of thermal solar systems for space heating and hot water production. The simulations are based on validated physical system models. The program offers complete freedom with regard to all parameters describing the systems and includes on-line help, economic evaluations and graphical output. This book describes the system considered in EURSOL, the mathematical algorithm, the physical model of each component used, the processing of solar radiation data and the economic evaluation criteria. Although the book is mainly a manual for the use of the simulation program, it is also a guide for the development of simplified simulation models for solar systems.

This book was released on 2017-03-04 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: District heating and cooling (DHC) combined with renewable energy sources can help meet rising urban energy needs, improve efficiency, reduce emissions and improve local air quality. Although currently dominated by fossil fuels such as coal and gas, DHC systems can be upgraded, or new networks created, to use solid biofuel, solar and geothermal energy technologies. Depending on local conditions, renewable-based DHC brings a range of benefits, including increased energy security, improved health and reduced climate impact.To date, only a few countries have taken advantage of their renewable resource potential for DHC or created policies to promote further uptake. Sweden and Switzerland have started promoting renewable-based district heating,while Denmark - with ambitious decarbonisation policies -already uses high shares. Many cities and regions envisage a growing role for district in their energy plans; some are also looking increasingly at district cooling.As this REmap sector study from the International Renewable Energy Agency (IRENA) shows, renewables could feasibly supply more than one fifth of the energy needed for DHC worldwide. But to drive the transition, policy makers need to fully understand the costs, bene¿ts and actual potential for renewable-based DHC.

Available in PDF, EPUB and Kindle. Book excerpt: With the increase in electricity prices and environmental concerns, new technologies are being developed to extract energy from every available source and store the excess energy generated for later usage. One such solution is provided by Thermal Energy Storage Systems. Solar radiation in summer can be stored inter-seasonally to provide heating in winter, while the cold from winter air can be used to run air conditioning in summer. This thesis studies in detail the solar thermal energy storage system used for domestic water heating purposes in a typical detached home in St. John's, Newfoundland, Canada. It introduces the topic, discusses the background and development of the systems, and presents the basic concept of what a solar thermal energy storage system is and how it works. As well, it focuses on the availability of solar radiation, which is important for analyzing how effective the system can be, considering that the amount of solar radiation is not constant throughout the earth. In-depth information on how thermal energy storage system functions and operates, along with an extensive review of the literature, is also featured. Studies including experimental and simulation models are reviewed, which helps to compare earlier approaches to the present handling of the problem. Additionally, to establish the findings of the thesis, a simulation model of solar thermal energy storage for domestic water usage is created with the help of SAM software. Various parameters of MATLAB software are taken into consideration as well to establish the desired design of the system. These design parameters are extensively explained, together with a discussion on the assumptions and design technologies considered for creating the model for the MATLAB and BEopt simulations. Overall, this thesis demonstrates a method of designing a solar water heating system with thermal storage that can provide hot water for a small house. SAM and HOMER, which are design models that calculate the consumption of hot water and cost for a system, are extensively utilized in the study.

This book was released on 2021 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space heating is required in almost every dwelling across the country for different periods of time. The thermal energy needed to meet a heating demand can be supplied using different conventional and/or renewable technologies. Solar energy is one example of a renewable resource that can be used for supplying heating needs. It can be utilized either by using photovoltaic panels to generate electricity, that in turn can be used to operate heaters, or by using solar thermal panels. Solar thermal panels obtain higher operating efficiencies than photovoltaic panels, but solar energy for heating purposes suffers from a mismatch between supply and demand. This problem can be solved by employing large tanks that serve as seasonal thermal energy storage units. This work focuses on assessing the performance of solar thermal panels in supplying the space heating needs of a single-family dwelling in two different cities in the United States. These panels are coupled to a cylindrical tank buried in the ground for seasonal and daily energy storage, and a heat exchanger to transfer heat to the home. Storage tank size, collector area, and the working fluid mass flow rate are investigated to determine adequate values for these parameters to enhance the overall system performance. In addition, the simulation timestep for the program and the spatial grid sizes used in the CFD (computational fluid dynamics simulation) model of the storage unit have been examined to determine values of each to keep the simulation time reasonable without substantial loss in accuracy. These results are obtained by mathematically modeling the system components, the solar thermal panels, the heat exchanger, and the storage tank; then programming this mathematical model in MATLAB. Parts of the developed computer code were obtained from previous work and have been modified to suit the purpose of this project. Flat plate solar panels have been chosen for use as the solar collectors. An unmixed, crossflow heat exchanger is considered for transferring the thermal energy from the glycol-water mixture in the collectors to the air in the house. The storage unit CFD simulation is composed of the tank, insulation, and ground surrounding the tank and is based on the SIMPLE algorithm developed by Patankar.

Available in PDF, EPUB and Kindle. Book excerpt: Faced with an ever-growing resource scarcity and environmental regulations, the last 30 years have witnessed the rapid development of various renewable power sources, such as wind, tidal, and solar power generation. The variable and uncertain nature of these resources is well-known, while the utilization of power electronic converters presents new challenges for the stability of the power grid. Consequently, various control and operational strategies have been proposed and implemented by the industry and research community, with a growing requirement for flexibility and load regulation placed on conventional thermal power generation. Against this background, the modelling and control of conventional thermal engines, such as those based on diesel and gasoline, are experiencing serious obstacles when facing increasing environmental concerns. Efficient control that can fulfill the requirements of high efficiency, low pollution, and long durability is an emerging requirement. The modelling, simulation, and control of thermal energy systems are key to providing innovative and effective solutions. Through applying detailed dynamic modelling, a thorough understanding of the thermal conversion mechanism(s) can be achieved, based on which advanced control strategies can be designed to improve the performance of the thermal energy system, both in economic and environmental terms. Simulation studies and test beds are also of great significance for these research activities prior to proceeding to field tests. This Special Issue will contribute a practical and comprehensive forum for exchanging novel research ideas or empirical practices that bridge the modelling, simulation, and control of thermal energy systems.

Download or read book Predictive Performance Simulation of Concentrated Solar Power Technologies in Three Selected Cities in Northern Nigeria written by Haruna Mohammed Muye and published by Anchor Academic Publishing. This book was released on 2015-11-24 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work a predictive performance simulation of Solar Tower and Parabolic Trough Concentrating Solar Power plants was undertaken for three sites in Northern Nigeria. The simulation was done using Solar Advisor Model (SAM). The three sites - Minna, Kano, and Sokoto - were selected based on their Direct Normal Irradiation (DNI) values and hours of sunshine per day which are comparable to that of the sites where Concentrated Solar Power (CSP) plants are operating in Southern Spain. The simulation process adopted for this study includes: configuration of receiver and collector components, selection of Heat Transfer Fluid (HTF) and specification of the operating temperatures, sizing and configuration of solar field, specification of power cycle design point, specification of the thermal storage parameters, and optimization of hour of thermal energy storage, solar multiple and cooling system. The results show that the Solar Tower plant is more favoured to be adopted for use in the study sites because it has higher annual electrical energy generation, a higher capacity factor and lower Levelised costs of electricity. The Net Present Value of the CSP plants at all the sites is positive implying that the project is economically viable. The study also showed that at solar multiple of 2, the levelised cost of electricity for both Solar Towers and Parabolic Troughs is the lowest, irrespective of the cooling system (wet or dry cooling). Solar multiple has no effect on the water usage irrespective of the CSP plant. Dry cooling system reduces the water usage by 86% and 95% for Solar Tower and Parabolic Trough plants, respectively. The annual electrical energy generations of the CSP plants increase with increasing solar multiple. Dry cooling systems reduce the annual electrical energy generation in the range of 7.3 to 7.5 percent for the Solar Tower plant and 8 to 9 percent for the Parabolic Trough plant.
