Book Description
Nowadays distributed energy resources (DER) can provide certain reactive power flexibility for voltage support in alternating current power systems. Besides local voltage support at the distribution level, the DER can also provide reactive power flexibility at the transmission-distribution (T-D) interface, which can improve the reactive power grid adequacy of the distribution level. The term reactive power grid adequacy describes the compliance level of a distribution grid with a predefined reactive power range at the T-D interface. However, a challenge in grid planning procedures is the consideration of the usually intermittent reactive power flexibility potential by the DER. This study aims to develop practicable grid planning procedures for advanced reactive power management at the T-D interface by making use of controllable reactive power sources at the distribution level, like DER and distributed reactive power compensators. The study is performed for a real German distribution grid section with very high-distributed generation.

Book Description
This book will be a collection of the papers presented in the 2021 International Joint Conference on Energy, Electrical and Power Engineering (CoEEPE’21), covering new and renewable energy, electrical and power engineering. It is expected to report the latest technological developments in the fields developed by academic researchers and industrial practitioners, with a focus on power electronics, energy storage and system control in energy and electrical power systems. The applications and dissemination of these technologies will benefit research society as new research directions are getting more and more inter-disciplinary which require researchers from different research areas to come together and form ideas jointly. It will also benefit the electrical engineering and power industry as we are now experiencing a new wave of industrial revelation, that is, electrification, intelligentization and digitalization of our transport, manufacturing process and way of thinking.

Book Description
AC/DC Microgrids are a small part of low voltage distribution networks that are located far from power substations, and are interconnected through the point of common coupling to power grids. These systems are important keys for the flexible, techno-economic, and environmental-friendly generation of units for the reliable operation and cost-effective planning of smart electricity grids. Although AC/DC microgrids, with the integration of renewable energy resources and other energy systems, such as power-to-gas, combined heat and power, combined cooling heat and power, power-to-heat, power-to-vehicle, pump and compressed air storage, have several advantages, there are some technical aspects that must be addressed. This Special Issue aims to study the configuration, impacts, and prospects of AC/DC microgrids that enable enhanced solutions for intelligent and optimized electricity systems, energy storage systems, and demand-side management in power grids with an increasing share of distributed energy resources. It includes AC/DC microgrid modeling, simulation, control, operation, protection, dynamics, planning, reliability and security, as well as considering power quality improvement, load forecasting, market operations, energy conversion, cyber/physical security, supervisory and monitoring, diagnostics and prognostics systems.

Book Description
Wind power is often held up as the most accessible and cost-effective route to reducing our reliance on fossil fuels and improving our energy independence, yet knowledge of what it offers is often clouded by myths and misunderstandings, which can hamper its adoption. This new book, the result of an ambitious project coordinated by the European Wind Energy Association, aims to present the facts about wind energy. It includes six sections discussing: technology grid integration economics of wind its industry and markets its environmental impacts the scenarios and targets for wind energy. Contributions are drawn from nine leading research bodies across Europe, and the material is global in its scope. It is therefore an essential resource and reference for those whose work or study demands an in-depth examination of the subject, and for anyone who wants detailed, accurate and up-to-date information on this key energy source.

Book Description
Americans' safety, productivity, comfort, and convenience depend on the reliable supply of electric power. The electric power system is a complex "cyber-physical" system composed of a network of millions of components spread out across the continent. These components are owned, operated, and regulated by thousands of different entities. Power system operators work hard to assure safe and reliable service, but large outages occasionally happen. Given the nature of the system, there is simply no way that outages can be completely avoided, no matter how much time and money is devoted to such an effort. The system's reliability and resilience can be improved but never made perfect. Thus, system owners, operators, and regulators must prioritize their investments based on potential benefits. Enhancing the Resilience of the Nation's Electricity System focuses on identifying, developing, and implementing strategies to increase the power system's resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur. It is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.

Book Description
This book evaluates a number of serious technical challenges related to the integration of renewable energy sources into the power grid using the DIgSILENT PowerFactory power system simulation software package. It provides a fresh perspective on analyzing power systems according to renewable energy sources and how they affect power system performance in various situations. The book examines load flow, short-circuit, RMS simulation, power quality, and system reliability in the presence of renewable energy sources, and presents readers with the tools needed for modeling, simulation, and analysis for network planning. The book is a valuable resource for researchers, engineers, and students working to solve power system problems in the presence of renewable energy sources in power system operations and utilities.

Book Description
This book addresses different algorithms and applications based on the theory of multiobjective goal attainment optimization. In detail the authors show as the optimal asset of the energy hubs network which (i) meets the loads, (ii) minimizes the energy costs and (iii) assures a robust and reliable operation of the multicarrier energy network can be formalized by a nonlinear constrained multiobjective optimization problem. Since these design objectives conflict with each other, the solution of such the optimal energy flow problem hasn’t got a unique solution and a suitable trade off between the objectives should be identified. A further contribution of the book consists in presenting real-world applications and results of the proposed methodologies developed by the authors in three research projects recently completed and characterized by actual implementation under an overall budget of about 23 million €.

Book Description
Risk-Based Energy Management: DC, AC and Hybrid AC-DC Microgrids defines the problems and challenges of DC, AC and hybrid AC-DC microgrids and considers the right tactics and risk-based scheduling to tackle them. The book looks at the intermittent nature of renewable generation, demand and market price with the risk to DC, AC and hybrid AC-DC microgrids, which makes it relevant for anyone in renewable energy demand and supply. As utilization of distributed energy resources and the intermittent nature of renewable generations, demand and market price can put the operation of DC, AC and hybrid AC-DC microgrids at risk, this book presents a timely resource. - Discusses both the challenges and solutions surrounding DC, AC and hybrid AC-DC microgrids - Proposes robust scheduling of DC, AC and hybrid AC-DC microgrids under uncertain environments - Includes modeling upstream grid prices, renewable resources and intermittent load in the decision-making process of DC, AC and hybrid AC-DC microgrids
