Para resolver problemas prácticos se requiere una fundamentación teórica sólida y todo problema de ingeniería es uno de economía. En este libro se profundiza en las respuestas a temas tan cruciales en el Analisis de Sistemas de Potencia tales como: (a) su representacion circuital (valores en tanto por uno); (b) los metodos numericos que se aplican para hallar su respuesta bajo condiciones balanceadas (flujos de potencia); (c) algoritmos eficientes para estudios de corto-circuito y (d) potencia de corto-circuito. Para cada tema se trata en detalle su justificacion y derivacion y se incluye un ejemplo ilustrativo. Logicamente es obligada una discusion comparativa de las ventajas e inconvenientes de cada metodo. Mediante la inclusion de apendices se busca que sea de interes tanto para los ya iniciados como para los principiantes aunque se sabe que el Analisis de Sistemas de Potencia es una aplicacion de la Teoria de Circuitos, los Metodos Numericos y del Algebra Lineal al estudio del comportamiento de una interconexion de aparatos reales tales como transformadores, sistemas de transmision y generadores. Se describen inicialmente los metodos clasicos que aunque en desuso enriquecen conceptualmente (es decir, como NO se hacen las cosas), y en una segunda etapa los metodos modernos. Por esta razon se incluyen temas como: (i) Formacion de la Matriz Admitancia de Nodos y su aplicacion a estudios de corto circuito; (ii) Factorizacion Triangular simple ([A] =[L][D][U]), con estrategia de pivote ([A]=[P][L][U]) e inversa ([A] 1); (iii) Formacion de la Matriz Impedancia de Nodos Dispersa y (iv) Metodos de Vector Disperso.

El libro muestra la capacidad de las redes neuronales y en concreto de los mapas auto-organizados de Teuvo Kohonen, los conocidos como Self-Organizing Maps (SOM) para clasificar consumidores eléctricos a partir de historicos de datos reales de consumo. El espectro de datos de entrada esta formado por mas de 20 tipos de consumidores distintos de una misma region geografica. La red neuronal SOM ha demostrado ser una eficaz herramienta para segmentar y clasificar consumidores a partir de sus perfiles de carga diarios y ha permitido identificar nuevos consumidores, no utilizados antes para entrenar el mapa. Esta identificacion posterior y la asignacion automatica a un segmento o cluster de clientes permiten asociar nuevos consumidores a patrones de consumo previamente clasificados. Este procedimiento permitiria a compañias comercializadoras y a clientes conocer a partir de los datos de consumo diario a que cluster de consumidores pertenece y elegir tarifas especificas en funcion del patron de consumo de este grupo.

Circular Energy: circular energy means recycling, take back the amount of energy used minus the amount of energy dissipated in the process of transforming energy from one form to another form, such as mechanical form to the electric form. Currently the human being uses the energy only once and discard the energy used, and consequently needs to produce the total amount of energy used and discarded.

The analyzes carried out by artificial intelligence must start from a complete and integrated data structure, which is classified and grouped with the intention of synergistically producing mental and predictive captures. In this perspective, the objective of this study is to analyze the possibility of contribution of artificial intelligence in guiding decision-making in the public planning of sustainable electrical matrices. The methodological procedures of this investigation, built a structure of analysis of electricity sources, based on the economic, social, environmental and technological dimensions; as well as a sectoral analysis structure of energy sustainability indicators, supported by linear correlations of an economic, social, environmental and political nature. The planning of electrical matrices, according to the inferences of this investigation, can use artificial intelligence as a strategic guide for decisions, as long as they are based on analysis structures focused on the strategic use of electricity sources and the use of sectoral and multidimensional indicators. This investigation constitutes an original contribution insofar as it discusses the possibilities of connections between artificial intelligence and the construction of electrical matrices, from the perspective of improving the decision-making process in Brazilian public planning. The discussion about these connections helps to raise subsidies for machine learning to process and develop methodologies, based on algorithms, that automate the construction of decision analysis models in the planning and sustainable construction of the use of electricity.

Electricity and Magnetism, a volume in Elisha Grays Natures Miracles series, offers a lucid, apparatus-centered tour of charge, current, induction, and magnetic action. Interweaving historical vignettesVolta, Faradays lines of force, Maxwells field picturewith plainspoken demonstrations and crisp woodcuts, Gray moves from benchtop effects to power stations. Eschewing heavy mathematics, he shows how dynamos, transformers, telegraph circuits, and early telephones enact the same field laws, exemplifying late nineteenthcentury popular science at its best: empirical, practical, and democratically didactic. An accomplished electrical engineer and prolific inventor, Gray co-founded the firm that became Western Electric, created the harmonic telegraph and telautograph, and famously contested priority in the invention of the telephone. Trained at Oberlin and seasoned in shop and laboratory, he writes with a practitioners economy and a teachers patience, translating workshop intuitions into household-scale experiments. The books emphasis on applications and on FaradayMaxwell concepts betrays a life spent bridging patent office, factory floor, and lecture hall, and a desire to make the new electric age intelligible to non-specialists. Recommended to general readers, educators, and historians seeking a clear, context-rich primer that complements mathematical treatises and captures electrification at the moment it entered everyday life.Quickie Classics summarizes timeless works with precision, preserving the authors voice and keeping the prose clear, fast, and readabledistilled, never diluted. Enriched Edition extras: Introduction · Synopsis · Historical Context · Brief Analysis · 4 Reflection Q&As · Editorial Footnotes.
