A major concern of island power systems is frequency stability. A power system is said to be frequency stable if its generators are able to supply their loads at a frequency within acceptable limits after a disturbance. Frequency instability occurs if load-generation imbalances are not corrected in appropriate manner and time. Since island power systems are more sensitive to frequency instability than large ones due to the smaller number of generators online and the lower inertia, they require a larger amount of primary reserve per generator. This book provides a worldwide overview of island power systems, describing their main features and issues. Split into two parts, the first part examines the technical operation, and in particular, frequency stability of island power systems and its technical solutions, including more efficient underfrequency load-shedding schemes. The chapters explore both conventional and advanced load-shedding schemes and consider the improvement of these schemes by making them more robust and efficient. Advanced devices are modelled and analyzed to enhance frequency stability and reduce the need for load shedding. In the second part, the economic operation of island power systems is explored in detail. For that purpose, regulations and economic operations (centralized vs. market scheme) are reviewed by the authors. The authors discuss models for renewable energy sources and for advanced devices and systems such as demand-side management, energy storage systems, and electric vehicles. This book will be critical reading to all researchers and professionals in power system planning and engineering, electrical/power delivery, RES and control engineering. It will also be of interest to researchers in signal processing and telecommunications and renewable energy, as well as power system utility providers.
After four decades from the 1982 war between Britain and Argentina over possession of the Falklands/Malvinas islands in the South Atlantic Ocean, this book allows for a new and rounded reading of the causes, course and consequences of the war. It provides a comprehensive overview of the Falkland/Malvinas War by integrating the military history of the conflict into the diplomatic, political, social and cultural aspects of the war. Including a substantial body of advocacy, chronicle, narrative and analysis, the volume draws upon an extensive range of published sources, in English and Spanish, primary sources from both sides and unpublished testimonies. The book, written by Argentine and Australian historians and scholars, discuss themes such as the background to the war, the offensive campaign for the islands and the English and Argentine experiences and memories of the war from the perspective of the islanders. Being part of the Wars and Battles of the World series, this book will be an essential read for scholars and researchers of military history, British history, Latin American history, defence and strategic studies, geopolitics and modern history.
The victory of Alfonsn's Radicals in the November 1983 elections surprised most political observers by its depth and clarity. In this important and topical book, two Argentinian socialists briefly chart the country's political and economic history, before moving on to discuss the full-scale restructuring of the economy organized by the ruling junta. It was the crisis of this model, with its explicit ambitions of regional power, which drove Galtieri into the Malvinas adventure. The authors persuasively argue that although the integration of these bleak, inescapably dependent offshore islands with Argentina represents the only progressive solution, the junta's goal of self-aggrandizement gave the operation a reckless and overwhelmingly reactionary stamp. Itself the result of the crisis of military rule, the disastrous war with Thatcher's Britain intensified all the contradictions of the regime and isolated it from its original base of support in society. A concluding section written for this edition analyses the significance of the election results, especially for the declining Peronist movement and the left-wing groups and parties that threw themselves behind the war. First publication in English of a major, critical work from Argentina on the Malvinas/Falklands War and its aftermath.
