“…In this O’Reilly report, Sean Patrick Murphy, Chief Data Scientist at PingThings, describes how data science is helping electric utilities make sense of a stochastic world filled with increasing uncertainty—including fundamental changes to the energy market and random phenomena such as weather and solar activity. Murphy also reviews several cutting-edge tools for storing and processing big data that he’s used in his work with electric utilities—tools that can help traditional engineers pursue a data-driven approach in many industries. …”

“…Distributed energy resources (DERs) are small-scale energy resources usually situated near sites of electricity use, such as rooftop solar panels and battery storage. Their rapid expansion is transforming not only the way electricity is generated, but also how it is traded, delivered and consumed.Accordingly, DERs can create new power system opportunities, but at the same time, can pose new challenges when a grid has not been properly prepared. …”

“…The text begins with a definition of harmonics, along with analytical expressions for electrical parameters under nonsinusoidal situations, and then: Discusses important and widely used industry standards to control harmonic distortion levels ;Describes methods to mitigate the effects of harmonics, detailing the operation principles and design of passive filters and active filter fundamentals ;Presents alternative methods, such as stiffer AC sources, power converters with increased number of pulses, series reactors, and load reconfiguration ;Reviews the elements that play a role in the study of the propagation of harmonic currents in a distribution network ;Explains how to determine power losses in electrical equipment attributed to harmonic waveform distortion ;Covers harmonics from solar and wind power converters and power electronics in FACTS and HVDC technologies ;Explores harmonics from electric vehicles connected to the grid, superconductive fault current limiters, and electric vehicle charging stations. …”

“…But what happens when supply becomes more variable and less certain, as with some renewable sources of electricity like wind and solar PV that fluctuate with the weather? To what extent can the resources that help power systems cope with the challenge of variability in demand also be applied to variability of supply? …”

“…Morocco has an abundance of renewable resources, especially wind and solar power, and is a regional leader in deploying clean energy technologies. …”

“…Es un libro clásico, ingenioso, que conviene leer para soñar, para no dejar nunca de ser pequeño. Desde que te hice mi amigo, eres único en el mundo, ayudará, sin duda, a ahondar y a saborear el contenido de El Principito…”

“…The analysis covers 87 countries, six renewable energy sectors (wind, solar, biomass, small hydropower, marine and geothermal) and the 2000-2011 time-span. …”

“…This book offers interdisciplinary elements to map the paths in which a group of authors whose life and work was marked, directly or indirectly, by the experience of exile cross: Max Aub, Luis Cernuda, José Gaos, Manuel García Morente, Juan Larrea , Eduardo Nicol, Alfonso Reyes, Josep Solanes and María Zambrano. The texts thematize the work, context, and influences of writers, poets, and philosophers who arrived in Latin America fleeing political persecution and the Civil War in Spain. …”

“…Analyses of these previously returned samples have led to major breakthroughs in the understanding of the age, composition, and origin of the solar system. Having the instrumentation, facilities and qualified personnel to undertake analyses of returned samples, especially from missions that take up to a decade or longer from launch to return, is thus of paramount importance if the National Aeronautics and Space Administration (NASA) is to capitalize fully on the investment made in these missions, and to achieve the full scientific impact afforded by these extraordinary samples. …”
