Most of the research and experiments in the fields of modeling and control systems have spent significant efforts to find rules from various complicated phenomena by principles, observations, measured data, logic derivations. The rules are normally summarized as concise and quantitative expressions or “models”. “Identification” provides mechanisms to establish the models and “control” provides mechanisms to improve system performances. This book reflects the relevant studies and applications in the area of renewable energies, with the latest research from interdisciplinary theoretical studies, computational algorithm development to exemplary applications. It discusses how modeling and control methods such as recurrent neural network, Pitch Angle Control, Fuzzy control, Sliding Mode Control and others are used in renewable systems. It covers topics as photovoltaic systems, wind turbines, maximum power point tracking, batteries for renewable energies, solar energy, thermal energy and so on. This book is edited and written by leading experts in the field and offers an ideal reference guide for researchers and engineers in the fields of electrical/electronic engineering, control system and energy.

A reliable and secure protection and control system is a paramount requirement for any electrical network. This book discusses protection and control schemes of various parts of Solar Power Plants (SPP) namely solar generator, inverter, and SPP network connected to the grid. For this purpose small, medium, and large size of solar power energy sources have been considered. This includes residential, commercial buildings and large power plants. There are significant literature about solar energy, modeling and different aspects of integration of SPP to grids. But there is no book to address directly the setting/design of protection and control schemes, testing techniques and fault findings of solar generators and its networks. The topology and characteristics of solar generators and their networks are different from conventional ones. This has caused the following issues: - Conventional protection & control scheme may fail to detect different type of faults which may occur on solar cells/panels/arrays, DC cables, and inverters. This necessitated the requirement of special schemes for the detection of faults in blind spots, - Fault findings required tests, and testing equipment for solar generators are different from conventional ones, - The fault current contribution from solar generators is low (1.1-1.2 pu) as compared to conventional ones. The above problems have caused significant challenges for appropriate setting and design of protection & control scheme of SPP network which in some cases have resulted to several major plants shut down, safety risks and fire incidents. This book discusses the above challenges and proposes mitigation techniques to rectify the deficiencies of existing industry practices for the protection and control systems of solar generators. Most of the content of this book has been observed or successfully applied in the field for various SPPs projects worldwide and consequently can be used or considered as a practical guideline for future projects. Main Objectives of the Book The main objectives of the book are: - To familiarize engineers, technical officers, testers, and project managers with required power system protection and control schemes of solar power plants (SPP). - To provide a guideline for preparation of standards, technical specification, business case, functional scope, test, and commissioning plan as applicable to the installation of new SPP; - To provide adequate information to electricity companies, consultants, contractors, relay manufacturers,s and SPP owners about the requirement of protection and control systems of SPP.

A revolution is ongoing in the field of small-scale energy solutions, which can enable lower impact on the environment, more robust supply and self-determination. Solar power and other forms of renewable energy sources, which you can implement to generate your own electricity, are growing quickly. Electromobility is transforming the car industry and transportation systems and can also play a role in your energy system. Electricity can be used much more efficiently than before, for example by using LED light, variable speed motor drives and efficient home appliances. Smart controls are available, sometimes with free open source software. All this opens up tremendous opportunities for energy independence, which is the focus of this book. The book introduces the reader to a number of renewable energy sources, to different options for storing electricity and to smart use of electricity, particularly in the context of small isolated systems. This is important because many renewable energy sources are weather- and season-dependent and usually require storage and smart control, in order to obtain a system that is completely independent of the electricity grid. In the book, overall system design is explained, including how to combine different sources in a hybrid system. Different system sizes and architectures are also covered. A number of real cases are described, where homes, businesses and communities have achieved a high level of energy independence or are on their way to achieving it. This book will prove useful in university education in renewable energy at bachelor and master level, and also for companies and private individuals, who want to start or expand activities in the area of renewable energy.
