    Book SynopsisVoltage-Enhanced Processing of Biomass and Biochar A detailed introduction to voltage-enhanced processing of carbonaceous materials While there are many well-established biomass processing techniques that are suitable for a variety of different situations, the utilization of voltage-driven techniques for the processing of biomass and biochar has been shown to have advantages for certain applications. Specifically, the field of thermal plasma gasificationwhere plasma provides the conversion energyis relied upon in certain commercial equipment that is already available on the market. Crucially, however, the field of non-thermal plasma pyrolysis and gasificationchemical reactions are intensified by the presence of the plasma dischargeis still a developing subject with a great scope for innovation in research and development. A timely book considering its potential applications in a greener market, Voltage-Enhanced Processing of Biomass and Biochar helpfully provides a detailed description of voltage-enhanced processing of carbonaceous materials. The book explains aspects of this processing method in thermal and non-thermal plasmas, as well as describing the effects of Joule heating as part of the temperature distribution and conversion rate. In many ways, this book presents a detailed description of different processes and plasma discharges currently available, with the provision of experimental and simulation results gathered over years of research and development. Importantly, it also offers many methods by which we can be environmentally friendly when working with biomass and biochar. Voltage-Enhanced Processing of Biomass and Biochar readers will also find: Simulation results of Joule heating of biomass, biochar, and pyrolytic graphite Descriptions of thermal plasma torches currently available in the marketAccounts of the experimental results of conversion utilizing steam plasmaComparison of results against provided numerical models that predict synthesis gas composition under the presence of thermal plasma discharge Voltage-Enhanced Processing of Biomass and Biochar is a useful reference for researchers and practitioners working on applications of plasma for the conversion of biomass and biochar, as well as graduate students studying mechanical, electrical, and chemical engineering.Table of ContentsContributors xi Preface xiii Acknowledgments xv Acronyms xvii Introduction xix 1 Carbonaceous Material Characterization 1 1.1 Material Characterization 2 1.1.1 Thermophysical properties 3 1.1.2 Moisture Content 3 1.1.3 Ultimate and Proximate analysis 4 1.1.4 Dielectric and electrical properties 4 1.2 Biomass 6 1.3 Biochar 7 1.3.1 Surface area, cation exchange capacity, and pH 9 1.4 Activated carbon 11 1.5 Pyrolytic graphite 11 Bibliography 12 2 Conventional Processing Methods 21 2.1 Biomass Processing 22 2.1.1 Biomass Pyrolysis 23 2.1.2 Biomass Gasification 26 2.2 Biochar production and post processing 28 2.2.1 Biochar Activation 34 Bibliography 44 3 Introduction to Plasmas 49 3.1 Thermal Plasmas 50 3.1.1 Mathematical model 53 3.2 Non-thermal Plasmas 56 3.2.1 DC non-thermal electrical discharges 59 3.2.2 Dielectric barrier discharge 64 3.2.3 Pulsed discharges 65 3.2.4 Gliding arc 66 3.2.5 Microwave-induced discharges 67 3.3 Impedance matching 68 3.4 Discharges in liquids 71 3.4.1 Contact glow discharge electrolysis 72 3.4.2 Plasma electrolysis with AC power 76 3.4.3 Gliding arc in glycerol for hydrogen generation 77 Bibliography 78 4 Voltage-Enhanced Processing of Biomass 85 4.1 Biomass gasification with thermal plasma 86 4.1.1 Plasma parameters 87 4.1.2 Syngas composition 88 4.1.3 Energy balance 92 4.1.4 Temperature decay in plasma/biomass discharge 95 4.2 Dielectric breakdown of biomass 97 4.2.1 Biomass-in-the-loop 98 4.3 Biomass gasification with non-thermal plasma 99 4.3.1 Tar breakdown 100 4.3.2 Circuit configuration 104 4.3.3 Scaling up of the technology 107 Bibliography 107 5 Voltage-Enhanced Processing of Biochar 113 5.1 DC Power Applied to Biochar 114 5.1.1 Joule heating of biochar 114 5.1.2 Joule heating of activated carbon 118 5.1.3 Recent Trends in Mathematical modelling 150 5.2 Physical activation of biochar with non-thermal plasma 159 5.2.1 Plasma-steam activation 160 Bibliography 162 6 Numerical simulations 167 6.1 Background 167 6.2 Modeling approaches 168 6.2.1 Kinetic approach 169 6.2.2 Fluid model approach 172 6.3 Examples of non-thermal plasma modeling 175 6.3.1 Cathode fall of a DC glow discharge 176 6.3.2 RF plasma discharge 179 6.3.3 Plasma chemistry 185 Bibliography 191 7 Control of plasma systems 195 7.1 Control of thermal plasma torches 196 7.1.1 Dynamics 198 7.1.2 Control 201 7.2 Control of nonthermal plasma discharges 207 7.2.1 Plasma diagnostics 208 7.2.2 AI-based control 209 Bibliography 214

    Book SynopsisEnergy Global energy demand has more than doubled since 1970. The use of energy is strongly related to almost every conceivable aspect of development: wealth, health, nutrition, water, infrastructure, education and even life expectancy itself are strongly and significantly related to the consumption of energy per capita. Many development indicators are strongly related to per-capita energy consumption. Fossil fuel is the most conventional source of energy but also increases greenhouse gas emissions. The economic development of many countries has come at the cost of the environment. However, it should not be presumed that a reconciliation of the two is not possible. The nexus concept is the interconnection between the resource energy, water, food, land, and climate. Such interconnections enable us to address trade-offs and seek synergies among them. Energy, water, food, land, and climate are essential resources of our natural environment and support our quality oTable of ContentsPreface or Foreword? 1.

This allows e-paper devices to have a wider range of viewing angles than traditional LED products and are capable of being viewed in direct sunlightand without any additional power. As a result, e-paper displays create less eye strain, have a greater flexibility in their use, and have the potential to be used in place of paper for billboard advertising, educational applications, and transport signage, and more. In E-Paper Displays, editor Bo-Ru Yang and his team of experts present a detailed view into the important technologies involved in e-paper displays, with a particlular emphasis on how this technology's unique properties make possible a wTable of ContentsList of Contributors xi Series Editor's Foreword xiii Editor's Preface xv 1 The Rise, and Fall, and Rise of Electronic Paper 1Paul S.

  • Mathematical Programming for Power Systems

    John Wiley & Sons Inc Mathematical Programming for Power Systems

    Book SynopsisExplore the theoretical foundations and real-world power system applications of convex programming In Mathematical Programming for Power System Operation with Applications in Python, Professor Alejandro Garces delivers a comprehensive overview of power system operations models with a focus on convex optimization models and their implementation in Python. Divided into two parts, the book begins with a theoretical analysis of convex optimization models before moving on to related applications in power systems operations. The author eschews concepts of topology and functional analysis found in more mathematically oriented books in favor of a more natural approach. Using this perspective, he presents recent applications of convex optimization in power system operations problems. Mathematical Programming for Power System Operation with Applications in Python uses Python and CVXPY as tools to solve power system optimization problems and includes mTable of ContentsAcknowledgment ix Introduction xi 1 Power systems operation 1 1.1 Mathematical programming for power systems operation 1 1.2 Continuous models 3 1.2.1 Economic and environmental dispatch 3 1.2.2 Hydrothermal dispatch 3 1.2.3 Effect of the grid constraints 5 1.2.4 Optimal power flow 5 1.2.5 Hosting capacity 7 1.2.6 Demand-side management 7 1.2.7 Energy storage management 9 1.2.8 State estimation and grid identification 9 1.3 Binary problems in power systems operation 11 1.3.1 Unit commitment 12 1.3.2 Optimal placement of distributed generation and capacitors 12 1.3.3 Primary feeder reconfiguration and topology identification 13 1.3.4 Phase balancing 13 1.4 Real-time implementation 14 1.5 Using Python 15 Part I Mathematical programming 17 2 A brief introduction to mathematical optimization 19 2.1 About sets and functions 19 2.2 Norms 22 2.3 Global and local optimum 24 2.4 Maximum and minimum values of continuous functions 25 2.5 The gradient method 26 2.6 Lagrange multipliers 32 2.7 The Newton’s method 33 2.8 Further readings 35 2.9 Exercises 35 3 Convex optimization 39 3.1 Convex sets 39 3.2 Convex functions 45 3.3 Convex optimization problems 47 3.4 Global optimum and uniqueness of the solution 50 3.5 Duality 52 3.6 Further readings 56 3.7 Exercises 58 4 Convex Programming in Python 61 4.1 Python for convex optimization 61 4.2 Linear programming 62 4.3 Quadratic forms 67 4.4 Semidefinite matrices 69 4.5 Solving quadratic programming problems 71 4.6 Complex variables 74 4.7 What is inside the box? 75 4.8 Mixed-integer programming problems 76 4.9 Transforming MINLP into MILP 79 4.10 Further readings 80 4.11 Exercises 81 5 Conic optimization 85 5.1 Convex cones 85 5.2 Second-order cone optimization 85 5.2.1 Duality in SOC problems 90 5.3 Semidefinite programming 92 5.3.1 Trace, determinant, and the Shur complement 92 5.3.2 Cone of semidefinite matrices 95 5.3.3 Duality in SDP 97 5.4 Semidefinite approximations 98 5.5 Polynomial optimization 102 5.6 Further readings 105 5.7 Exercises 106 6 Robust optimization 109 6.1 Stochastic vs robust optimization 109 6.1.1 Stochastic approach 110 6.1.2 Robust approach 110 6.2 Polyhedral uncertainty 111 6.3 Linear problems with norm uncertainty 113 6.4 Defining the uncertainty set 115 6.5 Further readings 121 6.6 Exercises 121 Part II Power systems operation 125 7 Economic dispatch of thermal units 127 7.1 Economic dispatch 127 7.2 Environmental dispatch 133 7.3 Effect of the grid 136 7.4 Loss equation 140 7.5 Further readings 143 7.6 Exercises 143 8 Unit commitment 145 8.1 Problem definition 145 8.2 Basic unit commitment model 146 8.3 Additional constraints 150 8.4 Effect of the grid 151 8.5 Further readings 153 8.6 Exercises 153 9 Hydrothermal scheduling 155 9.1 Short-term hydrothermal coordination 155 9.2 Basic hydrothermal coordination 156 9.3 Non-linear models 159 9.4 Hydraulic chains 162 9.5 Pumped hydroelectric storage 165 9.6 Further readings 168 9.7 Exercises 169 10 Optimal power flow 171 10.1 OPF in power distribution grids 171 10.1.1 A brief review of power flow analysis 173 10.2 Complex linearization 177 10.2.1 Sequential linearization 181 10.2.2 Exponential models of the load 182 10.3 Second-order cone approximation 184 10.4 Semidefinite approximation 188 10.5 Further readings 190 10.6 Exercises 190 11 Active distribution networks 195 11.1 Modern distribution networks 195 11.2 Primary feeder reconfiguration 196 11.3 Optimal placement of capacitors 200 11.4 Optimal placement of distributed generation 203 11.5 Hosting capacity of solar energy 205 11.6 Harmonics and reactive power compensation 208 11.7 Further readings 212 11.8 Exercises 212 12 State estimation and grid identification 215 12.1 Measurement units 215 12.2 State estimation 216 12.3 Topology identification 221 12.4 Ybus estimation 224 12.5 Load model estimation 228 12.6 Further readings 231 12.7 Exercises 232 13 Demand-side management 235 13.1 Shifting loads 235 13.2 Phase balancing 240 13.3 Energy storage management 246 13.4 Further readings 249 13.5 Exercises 249 A The nodal admittance matrix 253 B Complex linearization 257 C Some Python examples 263 C.1 Basic Python 263 C.2 NumPy 266 C.3 MatplotLib 268 C.4 Pandas 268 Bibliography 271 Index 281

    Book SynopsisPOWER QUALITY MEASUREMENT AND ANALYSIS USING HIGHER-ORDER STATISTICS Help protect your network with this important reference work on cyber security Power quality (PQ) in electrotechnical systems refers to a set of characteristics related to the movement of energy and the delivery of voltage to consumers in the highest standard. As electricity networks change and adapt to new technologies and concepts of energy within a future Smart Grid, it has become clear that standardized methods by which stability and accuracy of electrical service along a network are currently measured are no longer enough to solve inherent issues in service and ensure established requirements are met. Power Quality Measurement and Analysis using Higher-Order Statistics reflects the latest information related to PQ (Power Quality) analysis solutions, particularly that related to the implementation of new quality indices in the domain of higher-order statistics (HOS).
