This book describes the stochastic and predictive control modelling of electrical systems that can meet the challenge of forecasting energy requirements under volatile conditions. The global electrical grid is expected to face significant energy and environmental challenges such as greenhouse emissions and rising energy consumption due to the electrification of heating and transport. Today, the distribution network includes energy sources with volatile demand behaviour, and intermittent renewable generation. This has made it increasingly important to understand low voltage demand behaviour and requirements for optimal energy management systems to increase energy savings, reduce peak loads, and reduce gas emissions. Electrical load forecasting is a key tool for understanding and anticipating the highly stochastic behaviour of electricity demand, and for developing optimal energy management systems. Load forecasts, especially of the probabilistic variety, can support more informed planning and management decisions, which will be essential for future low carbon distribution networks. For storage devices, forecasts can optimise the appropriate state of control for the battery. There are limited books on load forecasts for low voltage distribution networks and even fewer demonstrations of how such forecasts can be integrated into the control of storage. This book presents material in load forecasting, control algorithms, and energy saving and provides practical guidance for practitioners using two real life examples: residential networks and cranes at a port terminal.

Energy storage systems (ESS) exist in a wide variety of sizes, shapes and technologies. An energy storage system's technology, i.e. the fundamental energy storage mechanism, naturally affects its important characteristics including cost, safety, performance, reliability, and longevity. However, while the underlying technology is important, a successful energy storage project relies on a thorough and thoughtful implementation of the technology to meet the project's goals. A successful implementation depends on how well the energy storage system is architected and assembled. The system's architecture can determine its performance and reliability, in concert with or even despite the technology it employs. It is possible for an energy storage system with a good storage technology to perform poorly when implemented with a suboptimal architecture, while other energy storage systems with mediocre storage technologies can perform well when implemented with superior architectures.

Photovoltaics is already an economic and practical option for providing electricity in many situations such as remote housing, in hybrid systems and for some service applications. Over the last decade, an International Energy Agency (IEA) team (Photovoltaic Power Systems, Task III) made up of members from 15 different countries has been studying these systems. Many valuable and practical lessons have been learned about economic, institutional, social and technical aspects of installing and using such systems. This book explains these lessons succinctly and clearly, and provides examples of fourteen practical, installed projects to illustrate them. Both PV specialists and non-specialists involved in the development, planning, commissioning, installation or use of stand-alone PV systems can benefit from the extensive experience of the Task members, and will find plenty of hints and guidelines within this concise publication to save them significant time and money. All members of the IEA Task have contributed to the book, which has been edited and coordinated by ECOFYS in The Netherlands. Published with IEA.

This book provides an overview of the fundamentals of plasmonic field enhancement phenomena and the recent advancements in the field of hydrogen energy technologies that utilize plasmonics for their performance enhancement. Hydrogen energy is currently a representative clean energy without polluting or greenhouse emission in its use. However, industrial production of hydrogen molecules, or other usable hydrogen-containing molecules, is required for the use of hydrogen energy. It is also important to produce hydrogen in clean, renewable manners, to contribute to the solution of the environmental problems, such as atmospheric pollution and global warming, and of the depletion of energy resources. For the widespread use of hydrogen energy, technical developments particularly for hydrogen production and storage are highly sought after. Free electrons in metals, particularly around metal surfaces or interfaces with dielectric materials, exhibit a strong interaction with electromagnetic fields or light in the form of collective oscillation, named surface plasmons. The electromagnetic field intensity around subwavelength-size metal particles can be highly localized due to the coupling between the incident photons and collective oscillation of free electrons at the metal surface, resulting in focusing of electromagnetic energy density, or namely local field enhancement.

Nuclear isomers are the long-lived excited states of nuclei. Therefore, they constitute the meta-stable landscape of nuclei. The first isomer was probably identified as early as 1921. Since then, the number of isomers has been growing steadily picking up pace in recent times. Interest in nuclear isomers has grown in recent years for many reasons. The experimental capabilities to observe isomers have been expanding to cover a wider time scale. This has opened up new windows to observe and decipher the underlying nuclear structure and interactions. Further, the isomers are beginning to be seen as potential energy storage devices and nuclear clocks with a host of applications. Possible discovery of a gamma ray laser has also ignited many researches in this area. Isomers now cover the full nuclear landscape with structural peculiarities specific to each region of the nuclear chart. Exploring the nuclear isomers, therefore, provides a novel insight into the nuclear structure properties of that region. There could be many different reasons for the long lives of excited nuclear states, which lead to the classification of isomers. Isomers are broadly classified in to four classes: Spin isomers, shape isomers, fission isomers and K-isomers. Seniority isomers have also been identified which are often clubbed with the spin isomers. We discuss this classification and the underlying causes in detail. Many examples are considered to highlight the large variety of isomers. The range of half-lives covered by the isomers varies from billions of years to nano-seconds and even small. To understand this vast variation is a fascinating endeavor in itself. The angular momentum couplings, nuclear shapes, pairing etc. conspire together to give this vast range of half-lives. We go through these aspects in detail, highlighting the various selection rules at work. It is interesting that the nuclear shapes play an important role in many types of isomers. The spin isomers, which occur in spherical or, near-spherical nuclei, are generally confined to the magic numbers. Seniority isomers are largely found in semi-magic nuclei and should be explored in conjunction with the spin isomers. New developments in seniority and generalized seniority isomers are discussed in detail. As the nuclei deform; the nature of isomers changes. We take a close look into the decay properties of isomers in deformed nuclei, particularly the K isomers, the shape isomers and the fission isomers. While doing so, the theoretical and experimental developments of isomers are also addressed. A number of open questions are posed for possible new experiments and better understanding of the isomers.
