This book provides a manual for the technical and structural design of systems for supplying decentralised energy in residential buildings. It presents the micro-combined cooling, heating & power systems Stirling engines & renewable energy sources (mCCHP-SE-RES) systems in an accessible manner both for the public at large, and for professionals who conceive, design or commercialise such systems or their components. The high performance levels of these systems are demonstrated within the final chapter by the results of an experiment in which a house is equipped with a mCCHP-SE-RES system. The reader is also familiarized with the conceptual, technical and legal aspects of modern domestic energy systems; the components that constitute these systems; and advanced algorithms for achieving the structural and technical design of such systems. In residential buildings, satisfying demands of durable development has gradually evolved from necessity to obligation and institutionalisation. Consequently a major paradigm change has appeared in the supply of energy to residential buildings, from the centralised production of energy using fossil fuels to the decentralised production of energy using local renewable sources. Furthermore, on the energy system market, energy micro systems which use renewable energy sources are increasingly commercialised. From among these, the mCCHP-SE-RES systems are particularly striking because they offer a high performance and they enhance the relationship between humans and the environment. This book is intended for postgraduate students of electrical engineering, applied mathematicians, and researchers of modelling and control of complex systems or power system technologies.

This thesis investigates the different strategies of operation and optimization criteria that a CCHP system can be operated under. As energy concerns increase, a major issue for the United States will be the efficiency of energy production. Due to this desire for the most efficient supply of energy CCHP will play an increasingly important role in both domestic and commercial applications as waste heat utilization provides an added measure of efficiency. The different strategies of operation under which a CCHP system can be operated under, electric load following and thermal load following, are defined in addition to the different optimization criteria that a CCHP system can be operated under. The different strategies and optimization criteria of CCHP operation are simulated for five various climate regions in the United States and the results for primary energy consumption, CO2 emissions, and cost of operation are compared.

Combined Cooling, Heating and Power (CCHP) presents an opportunity in commercial buildings to reduce electrical loads while increasing efficiency and emissions. In particular, High Temperature Fuel Cells (HTFCs) coupled with Absorption Chillers represent an opportunity to provide electricity, heating, and cooling to buildings at very high efficiencies. Because this combination has been demonstrated on only a few occasions, a need is evident for detailed system modeling and optimization to assure that the technology can meet its full potential and serve a wide variety of applications. In this thesis, the installation of a HTFC-Absorption Chiller system is analyzed and modeled in order to determine a favorable strategy for installation into an existing but generic commercial office building. Building loads were monitored and analyzed to establish the building electrical and HVAC demand. For the purposes of this system analysis, the HTFC is assumed to operate at steady state at all times. A steady state absorption chiller model was created in Aspen Plus® in order to analyze different operating points, given varied fuel cell exhaust conditions. Next, a dynamic absorption chiller model was created in Matlab Simulink®. This thermodynamic model incorporated mixing volumes, thermal mass, and transport delay in order to capture transient effects in the absorption chiller. The Aspen Plus® and Simulink® absorption chiller models were verified against manufacturer provided steady state data. Since the exhaust leaving the fuel cell during normal operating conditions was too high, analyses were performed with the steady state model to determine the best methods of reducing the temperature of the fuel cell exhaust. In parallel, simulations were run with the transient model to determine the ability of the absorption chiller to follow dynamic cooling loads throughout the day. Finally, representative load days were simulated while imposing operational constraints on the dynamic absorption chiller model. The use of a thermal energy storage (TES) tank was also analyzed. The most simple temperature reduction method, which alters the fuel cell steam-to-carbon ratio, is favored, combined with methods of diverting unnecessary exhaust from the chiller and sending it to a heat recovery unit. A heating-only mode, with the chiller configured for heat recovery, is the most effective method for energy utilization during the winter, when the cooling demand is marginal.

Many of the economic road blocks which have previously served to discourage the implementation of alternative power generation technologies can now be readily overcome through effective energy resource optimization. It is now a fact that solid financial returns can be achieved from combined heating, cooling and power generation projects by integrating energy and cost efficiency goals, and seeking a match between power production and heating/cooling requirements. This book is intended to serve as a road map to those seeking to realize optimum economic returns on such projects. The first section provides an introduction to basic heat and power thermodynamics, with an overview of heat and power generation technologies and equipment. The second section explores the infrastructure in which the project must be implemented, including environmental considerations, as well as utility rate structures. The third section provides detailed coverage of a broad range of technology types, and discusses how opportunities for their application can be identified and successfully exploited. The final section takes you through each step of project development, implementation and operation. Numerous examples are provided of actual field applications, with supporting documentation of system layouts and performance. The text is supplemented with more than one thousand graphics, including photos, cutaway drawings, layout schematics, performance curves, and data tables.

The goal of this study is to assess the potential of the Stirling engine in alternative energy applications including combined cooling, heating, and power (CCHP) and novel waste heat recovery (WHR) technologies. A first and second law model is developed to quantify Stirling engine performance and realize the crucial parameters in Stirling engine design. In addition, analysis of systems employing the Stirling engine as a prime mover can help justify particular design interests for the engine regarding certain applications. A model of a CCHP system is developed with a Stirling engine prime mover. Sensitivity analysis is performed on the CCHP system to gain a deeper understanding of how each component affects the overall performance of the CCHP system. The main objective of these analyses is to provide information on the feasibility of Stirling CCHP on the basis of primary energy consumption and cost. Finally, the potential of the Stirling engine as a waste heat recovery device is investigated. A thermodynamic model is developed to provide estimates of Stirling engine performance based on an available waste heat stream from any specific heat source, while suggesting practical design constraints on the engine based on bounds from the second law. These results are provided to strengthen the feasibility of the Stirling engine as a bottoming prime mover rather than the central power plant.

Combined cooling, heating and power (CCHP) systems are power generation stations designed for maximum waste heat recovery and energy sustainability. In a conventional CCHP system, a gas turbine provides the electrical generation and the waste heat is recovered for cooling and heating. Traditionally, utility-scale CCHP plants of 100 MW or more were commissioned to support large industrial processing plants. Light industry, commercial, and institutional applications have adopted smaller CCHP systems to realize economic savings and environmental benefits. Besides facing operating constraints such as smaller foot-print, shorter reaction time and shorter control tolerances, these plants also encounter low energy demands because of diurnal or seasonal variations, forcing them to operate at part-load. Coupled with relatively high capital and O & M costs, compact CCHP stations then become uneconomical for end-users. From flexibilities in operation, however, there are ample opportunities for favorable economic dispatch by operating the plant under demand response programs and ancillary services. The small-scaled CCHP systems fall under the distributed generation (DG) category of many regulatory policies and electricity rate tariffs of utilities. Several typical rate structures applicable to CCHP systems were evaluated, including standby and non-standby time-of-use (TOU), and critical peak pricing (CPP). The economic analysis produced insights on novel and preferred chiller dispatch strategies for energy and demand charge reduction. The increased variability and uncertainty of renewable generation add to the balancing duties of grid regulators whom previously had to deal with such behaviors in system load. The situation is becoming direr for California, as the state mandates 33% renewable resource generation by 2020 along with a plethora of stringent environmental legislation that would displace 18,000 MW of traditional base-load plants by 2020. Therefore, ancillary services will become more valuable as grid balancing authorities such as CAISO seek to address the uncertainty and variability in renewable generation. A gas turbine-driven CCHP system is one example of an ancillary service provider capable of complementing the increased renewable penetration. This dissertation seeks to elucidate the feasibility of implementing CCHP technology to light industrial and commercial applications for favorable economic dispatch to complement demand response services and renewable integration.

Combined cooling, heating and power (CCHP) systems are known as trigeneration systems, designed to provide electricity, cooling and heating simultaneously. The CCHP system has become a hot topic for its high system efficiency, high economic efficiency and less greenhouse gas (GHG) emissions in recent years. The efficiency of the CCHP system depends on the appropriate system configuration, operation strategy and facility size. Due to the inherent and inevitable energy waste of the traditional operation strategies, i.e., following the electric load (FEL) and following the thermal load (FTL), more efficient operation strategy should be designed. To achieve the highest system efficiency, facilities in the system should be sized to match with the corresponding operation strategy. In order to reduce the energy waste in traditional operation strategies and improve the system efficiency, two operation strategy design methods and sizing problems are studied (In Chapter 2 and Chapter 3). Most of the improved operation strategies in the literature are based on the ''balance'' plane, which implies the match of the electric demands and thermal demands. However, in more than 95% energy demand patterns, the demands cannot match with each other at this exact ''balance'' plane. To continuously use the ''balance'' concept, in Chapter 2, the system configuration is modified from the one with single absorption chiller to be the one with hybrid chillers and expand the ''balance'' plane to be a ''balance'' space by tuning the electric cooling to cool load ratio. With this new ''balance'' space, an operation strategy is designed and the power generation unit (PGU) capacity is optimized according to the proposed operation strategy to reduce the energy waste and improve the system efficiency. A case study is conducted to verify the feasibility and effectiveness of the proposed operation strategy. In Chapter 3, a more mathematical approach to schedule the energy input and power flow is proposed. By using the concept of energy hub, the CCHP system is modelled in a matrix form. As a result, the whole CCHP system is an input-output model. Setting the objective function to be a weighted summation of primary energy savings (PESs), hourly total cost savings (HTCs) and carbon dioxide emissions reduction (CDER), the optimization problem, constrained by equality and inequality constraints, is solved by the sequential quadratic programming (SQP). The PGU capacity is also sized under the proposed optimal operation strategy. In the case study, compared to FEL and FTL, the proposed optimal operation strategy saves more primary energy and annual total cost, and can be more environmental friendly. Finally, the conclusions of this thesis is summarized and some future work is discussed.
