  • How Does Solar Energy Transformed into Electricity?

    Many years ago, solar energy was never been the subject of all talks. Basically because the solar energy was never given that importance in people’s day to day life before. They just ignore and did not give attention on its importance. They fail to realize the importance of it. Now, as the period of modernized society where new technologies and innovations occurred came, the demand for ...

  • What the heck is a smart grid anyway?

    You know the old adage, ‘Never talk about politics or religion in polite company’? I’m beginning to think we need to add a third restraint, one against debate over the meaning of smart grid.Okay, it’s not exactly a dinnertime topic. But I’ve discovered in gatherings of energy nerds (I’m one), discussion can become fairly heated over what constitutes “smart grid.”On the one side are the ...

  • Cascade failures and distributed generation in power grids

    Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

  • Application of the LBM with adaptive grid on water hammer simulation

    A lattice Boltzmann method (LBM) is utilized to solve single-phase transient flow in pipes. In order to eliminate grid limitation related to the method of characteristics, governing equations are modified using appropriate coordinate transformation. The introduced modification removes connection between Courant number and spatial disposition of the computational nodes, forming a more flexible ...

  • Smart grid and stupid buildings: Can this marriage survive?

    Smart grid is still in its honeymoon phase. Hardly a day goes by without fanfare in the news about how it will reform building energy use. Maybe so. But for the marriage of smart grid and US buildings to work, someone's got to change. Is the stupid building up to the task? “Wiring the Smart Grid for Energy Efficiency,' a white paper by Oregon-based Portland Energy Conservation Inc (PECI), brings ...

  • Modelling photochemical air pollutant formation in Hungary using an adaptive grid technique

    A regional air quality model has been developed that describes the transport and chemical transformation of photochemical oxidants across Central Europe using an adaptive gridding method to achieve high spatial resolution. High-resolution emission inventories for Budapest and Hungary were utilised. The air pollution episode in August 1998 was modelled using a fixed coarse grid (mesh size 70 km) a ...

  • A complex network approach for identifying vulnerabilities of the medium and low voltage grid

    The vision behind the smart grid promises, among other things, to bring more attention to the lower layers of the distribution network where users are gradually transforming into prosumers. Independent of this transformation, users will expect the same (or higher) level of reliability of the infrastructure. In this paper, we consider physical samples from the Dutch medium and low voltage network ...

  • US plant shutdowns, grid focus drive storage growth: Greensmith CEO

    Power plant closures and hiking transmission costs are driving up US utilities’ investment in renewable energy storage, John Jung, CEO of Greensmith, an energy storage services firm, told Wind Energy Update. Some 60 GW of US coal-fired capacity is set to close between 2012 and 2020, according to the EIA. Nuclear plant lifespans will end and the US plans $180bn in planned transmission ...

  • An Action Plan to Integrate Plug-in Electric Vehicles with the U.S. Electrical Grid

    Executive Summary: Americans purchased almost 18,000 plug-in electric vehicles (PEVs) in 2011, a strong first year for these transformative vehicles. Recently, private industry and government have invested valuable resources in developing, promoting, and deploying PEVs. These vehicles offer an uncommon opportunity to address energy security, air quality, climate change, and economic growth. ...

  • A new time–frequency approach for hybrid differential and impedance protection of transmission lines

    A new current differential protection of transmission lines is presented in this paper using an S–transform variant having very fast computational speed suitable for real–time applications. The conventional S–transform used earlier for transmission line protection has large computational overhead and thus is not suitable for generating decisions regarding the occurrence of a fault and its type on ...
