Book Description :

Abstract: The renewed interest towards the low range power plants operating solicits the search of optimal solutions in terms of several key aspects: - The optimization of the thermal cycle in relation with the heat addition source, say an externally fired combustor, solar energy collectors, or waste heat from topping processes, together with the choice of the most favorable operating fluid. - The realization of the power plant with affordable costs, so more suitable with its employment as a distributed energy systems. This paper deals, in particular, with a combined cycle plant consisting of a topping micro-gas turbine (MGT) and of a bottoming ORC system (fig. 1 and fig. 2). A hybrid energy source is considered by means of the integration of the conventional fuel supply with a solar field. The authors' work proceeds with the optimization of several main parameters, say: - The location and the size of the solar field (with parabolic trough assembly) and, therefore, of the temperature limits of the compressed air in the MGT; - The more appropriate working fluid in the ORC bottoming plant; - The off-design response for the best adaptation of the system to variable heat and power demands and to changes in the solar radiation intensity.

Book Description :

This book provides a platform for scientists and engineers to comprehend the technologies of solar wind hybrid renewable energy systems and their applications. It describes the thermodynamic analysis of wind energy systems, and advanced monitoring, modeling, simulation, and control of wind turbines. Based on recent hybrid technologies considering wind and solar energy systems, this book also covers modeling, design, and optimization of wind solar energy systems in conjunction with grid-connected distribution energy management systems comprising wind photovoltaic (PV) models. In addition, solar thermochemical fuel generation topology and evaluation of PV wind hybrid energy for a small island are also included in this book. Since energy storage plays a vital role in renewable energy systems, another salient part of this book addresses the methodology for sizing hybrid battery-backed power generation systems in off-grid connected locations. Furthermore, the book proposes solutions for sustainable rural development via passive solar housing schemes, and the impacts of renewable energies in general, considering social, economic, and environmental factors. Because this book proposes solutions based on recent challenges in the area of hybrid renewable technologies, it is hoped that it will serve as a useful reference to readers who would like to be acquainted with new strategies of control and advanced technology regarding wind solar hybrid systems

Book Description :

Abstract: This paper starts from the results of the paper "Combined MGT – ORC solar – hybrid system. Part A: plant optimization PART A" and, as far as the selection of the ORC expander is concerned, different solutions are compared between radial turbines, volumetric and scroll expanders. A preliminary extended similarity study aids the search of the most suitable expander to be adapted to the ORC application. Actually, the most critical aspects regard the change in the operating fluid with dramatically different characteristics in terms of compressibility effects, molecular weight, and transport properties. Once the adaptability of an existing expander to such a different fluid has been detected, the effectiveness of this choice is validated by a CFD analysis. The component analysis is completed by the investigation of the reacting flow through the MGT combustor supplied with natural gas or biogas.

Book Description :

Master's Thesis from the year 2020 in the subject Engineering - Power Engineering, grade: 1.0, Technical University of Berlin (Technische Universität Berlin), course: Energy Engineering Master of Science program, language: English, abstract: The thesis shows the process of sizing and optimizing a solar Photovoltaics (PV) system for an off-grid resort with desalination loads in Marsa Alam, Egypt. Through load profile management, an optimal hybrid solar PV-diesel system, in the sense of maximum solar share that could be achieved without using energy storage while avoiding surpluses, is analyzed and presented. The self- consumption analysis aim was to determine the optimal PV system size in two load profile case scenarios that would give a SCR of not less than 90 percent to avoid surpluses in the hybrid system. Then an economic analysis for the optimal system sizes was conducted to measure and compare the economic benefits of implementing a hybrid solar PV-diesel system. It accounts for three different scenarios for the projection of future diesel prices in Egypt.

Book Description :

Electricity is a quantity, commodity that everyone want from charging a phone to running a factory the ever growing demand of electricity renewable energy resources are the most important and easy sources of energy yet non-polluting. Wind energy is the most efficient way of generating electricity. The self-excited induction generator (SEIG) is the best suited isolated generation system due to its simple and robust construction, reduced unit cost and easy maintenance. In the same way. Photo-voltaic power is also another promising energy source. Wind power and PV power are complimentary because strong winds are mostly to occur during night time and cloudy days whereas sunny days are often come with weak winds. Hence, Wind-Solar hybrid generation system can offer higher reliability to maintain continuous power output than other individual power generation system. The stand alone wind- solar hybrid generation system is valuable to use. Therefore it is important to study the performance of standalone wind-solar hybrid generation system under steady-state and dynamic condition for the optimum utilization of its meritorious features. This article is a simple and generalized fuzzy logic based intelligent controller is proposed, which is suitable and for autonomous operation of solar energy conversion or for isolated hybrid energy conversion.

Book Description :

Solar-wind hybrid systems are discussed. It is shown that there are large areas in the United States where solar and wind resources are comparable in magnitude and there are diurnal and seasonal complementarities which offer the potential for cost-effective hybrid systems. There are also distinct engineering features of the two conversion technologies. Electric power generation from wind is straightforward and cost-effective, whereas solar thermal conversion to generate heat is more cost-effective than to generate electricity. Examples of hybrid systems utilizing these features in total energy applications are presented.

Book Description :

Energy Storage not only plays an important role in conservinq the energy but also improves the performance and reliability of a wide range of energy systems. Energy storagp. leads to saving of premium fuels and makes the system morA cost effective by reducing the wastage of energy. In most systems there is a mismatch between the energy supply and energy demand. The energy storage can even out this imbalance and thereby help in savings of capital costs. Enerqy storage is all the more important where the enerqy source is intermittent such as Solar Energy. The use of jntermittent energy sources is likely to grow. If more and more solar energy is to be used for domestic and industrial applications then energy storage is very crucial. If no storage is used in solar energy systems then the major part of the energy demand will be met by the back-up or auxiliary energy and therefore the so called annual solar load fract]on will be very low. In case of solar energy, both short term and long term energy storage systems can be used whjch can adjust the phase difference between solar energy supply and energy demand and can match seasonal demands to the solar availability respectively. Thermal energy storage can lead to capital cost savings, fuel savjngs, and fuel substitution in many application areas. Developing an optimum thermal storaqe system is as important an area of research as developinq an alternative source of energy.

Book Description :

This study develops the conceptual design for a commercial-scale (nominal 100 MWe) central receiver solar/fossil fuel hybrid power system with combined cycle energy conversion. A near-term, metallic heat pipe receiver and an advanced ceramic tube receiver hybrid system are defined through parametric and market potential analyses. Comparative evaluations of the cost of power generation, the fuel displacement potential, and the technological readiness of these two systems indicate that the near-term hybrid system has better potential for commercialization by 1990. Based on the assessment of the conceptual design, major cost and performance improvements are projected for the near-term system. Constraints preventing wide-spread use were not identified. Energy storage is not required for this system and analyses show no economic advantages with energy storage provisions. It is concluded that the solar hybrid system is a cost effective alternative to conventional gas turbines and combined cycle generating plants, and has potential for intermediate-load market penetration at 15% annual fuel escalation rate. Due to their flexibility, simple solar/nonsolar interfacing, and short startup cycles, these hybrid plants have significant operating advantages. Utility company comments suggest that hybrid power systems will precede stand-alone solar plants.
