Chapter 1: Introduction

Abstract

In this chapter, after a brief review of chapters of this book, classifications of various models as well as various optimization problems applicable to energy systems were discussed. As the main step for optimization of energy systems, problem formulation was discussed thoroughly. However, the true formulation of an energy system is the subject of future chapters; for two simple examples, typical formulations in the form of a standard optimization problem were presented. Finally, the required steps for any modeling and optimization of an energy system were discussed briefly.

1.1: Preface

Improvement and optimization of energy systems are the concern of scientists and engineers for decades. The first step for this goal is providing a model that describes the system's behaviors. Then, using the employed model(s), the performance of the system is assessed, and if it is necessary, the system is either improved or optimized with the required tools. Therefore, the critical step for any improvement or optimization task is developing a model to describe the energy system from concerning aspects. In this regard, different types of models are usually developed, including thermal model, economic model, thermoeconomic model, environmental model, thermoenvironmental model, and empirical model. The goal of this book is to provide fundamentals of modeling, assessment, and optimization of energy systems. The contents of this book can be used by graduate students, engineers, and researchers in the field of energy and thermal systems.

1.2: Outline

This chapter provides the goal, scope, audience, and the outline of this book. Moreover, in this chapter, a brief review of the various classifications of models for energy systems as well as problem formulation is given too.

In Chapter 2, the fundamentals of thermal modeling based on thermodynamic models will be presented. Since the exergy is the rational thermodynamic parameter to express the energetic transaction of any energy system, after a brief review of thermodynamic concepts, fundamental to exergetic analysis will be provided in Chapter 2.

Advanced thermal models, including concepts of the finite-time thermodynamics (FTT), finite-speed thermodynamics (FST), combined FTT-FST models, quasi-steady models, and comprehensive thermal models are given in Chapter 3. In addition, in this chapter, basics regarding numerical and dynamic models are pointed out; however, detail regarding this numerical modeling is out of the scope of this chapter.

Combined thermal, economic, and environmental models are described in Chapter 4. Since exergy analysis is not able to consider the associated cost of energy streams, a more sophisticated tool is required for this purpose; therefore, exergoeconomic (thermoeconomic) modeling and analysis of energy systems is discussed in Chapter 4. In a similar analogy to exergoeconomics, the exergoenvironmental models have been introduced in Chapter 4 too. Moreover, in this chapter, a brief review of the combined exergoeconomic and ex...
