Advanced Control & Optimization Paradigms for Energy System Operation and Management
by Kirti Pal Saurabh Mani Tripathi Shruti PandeyDistributed energy technologies are gaining popularity nowadays; however, due to the highly intermittent characteristics of distributed energy resources, a larger penetration of these resources into the distribution grid network becomes of major concern. The main issue is to cope with the intermittent nature of the renewable sources alongside the requirements for power quality and system stability. Unlike traditional power systems, the control and optimization of complex energy systems comprising of wind, solar, thermal, and energy storage becomes difficult in many aspects, such as modelling, integration, operation, coordination and planning etc. This means that energy conversion as per the standards imposed by the energy market is unachievable without adequate control, management, and optimization.This edited book serves as a resource for the engineers, scientists and professionals working on distributed energy systems. The book is an extensive collection of state-of-the-art studies on advanced control paradigms for complex energy systems, with emphasis on the optimization and management of the high penetration of distributed energy resources into power distribution networks.

Advanced Control Methodologies For Power Converter Systems (Studies in Systems, Decision and Control #413)
by Ligang Wu Jianxing Liu Yunfei Yin Wensheng Luo Xiangyu ShaoThis book aims to present some advanced control methodologies for power converters. Power electronic converters have become indispensable devices for plenty of industrial applications over the last decades. Composed by controllable power switches, they can be controlled by effective strategies to achieve desirable transient response and steady-state performance, to ensure the stability, reliability and safety of the system. The most popular control strategy of power converters is the linear proportional–integral–derivative series control which is adopted as industry standard. However, when there exist parameter changes, nonlinearities and load disturbances in the system, the performance of the controller will be significantly degraded. To overcome this problem, many advanced control methodologies and techniques have been developed to improve the converter performance. This book presents the research work on some advanced control methodologies for several types of power converters, including three-phase two-level AC/DC power converter, three-phase NPC AC/DC power converter, and DC/DC buck converter.

Advanced Crop Improvement, Volume 1: Theory and Practice
by Aamir Raina Mohammad Rafiq Wani Rafiul Amin Laskar Nasya Tomlekova Samiullah KhanAs per the reports of FAO, the human population will rise to 9 billion by the end of 2050 and 70% of more food must be produced over the next three decades to feed the additional population. The breeding approaches for crop improvement programs are dependent on the availability and accessibility of genetic variation, either spontaneous or induced by the mutagens. Plant breeders, agronomists, and geneticists are under constant pressure to expand food production by employing innovative breeding strategies to enhance yield, adaptability, nutrition, resistance to biotic and abiotic stresses. In conventional breeding approaches, introgression of genes in crop varieties is laborious and time-consuming. Nowadays, new innovative plant breeding techniques such as molecular breeding and plant biotechnology, supplement the traditional breeding approaches to achieve the desired goals of enhanced food production. With the advent of recent molecular tools like genomics, transgenics, molecular marker-assisted back-crossing, TILLING, Eco-TILLING, gene editing, CRISPR CAS, non-targeted protein abundant comparative proteomics, genome wide association studies have made possible mapping of important QTLs, insertion of transgenes, reduction of linkage drags, and manipulation of genome. In general, conventional and modern plant breeding approaches would be strategically ideal for developing new elite crop varieties to meet the feeding requirement of the increasing world population.This book highlights the latest progress in the field of plant breeding, and their applicability in crop improvement.

Advanced DC/AC Inverters: Applications in Renewable Energy (Power Electronics, Electrical Engineering, Energy, and Nanotechnology)
by Fang Lin Luo Hong YeDC/AC inversion technology is of vital importance for industrial applications, including electrical vehicles and renewable energy systems, which require a large number of inverters. In recent years, inversion technology has developed rapidly, with new topologies improving the power factor and increasing power efficiency. Proposing many novel approaches, Advanced DC/AC Inverters: Applications in Renewable Energy describes advanced DC/AC inverters that can be used for renewable energy systems. The book introduces more than 100 topologies of advanced inverters originally developed by the authors, including more than 50 new circuits. It also discusses recently published cutting-edge topologies. Novel PWM and Multilevel Inverters The book first covers traditional pulse-width-modulation (PWM) inverters before moving on to new quasi-impedance source inverters and soft-switching PWM inverters. It then examines multilevel DC/AC inverters, which have overcome the drawbacks of PWM inverters and provide greater scope for industrial applications. The authors propose four novel multilevel inverters: laddered multilevel inverters, super-lift modulated inverters, switched-capacitor inverters, and switched-inductor inverters. With simple structures and fewer components, these inverters are well suited for renewable energy systems. Get the Best Switching Angles for Any Multilevel Inverter A key topic for multilevel inverters is the need to manage the switching angles to obtain the lowest total harmonic distortion (THD). The authors outline four methods for finding the best switching angles and use simulation waveforms to verify the design. The optimum switching angles for multilevel DC/AC inverters are also listed in tables for quick reference. Application Examples of DC/AC Inverters in Renewable Energy Systems Highlighting the importance of inverters in improving energy saving and power-supply quality, the final chapter of the book supplies design examples for applications in wind turbine and solar panel energy systems. Written by pioneers in advanced conversion and inversion technology, this book guides readers in designing more effective DC/AC inverters for use in renewable energy systems.
