  • 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 ...

  • Societal transformation: how radical does it need to be?

    It’s well known that Americans consume more resources on a per capita basis than citizens of other developed countries. In fact, research shows that if people in all nations used as many resources as the average American, we would need five Earths to meet this global resource ...

  • How solar is transforming an old mining town

    You hike over the crest of the hill and there it is: 96 sun-tracking solar masts, each with 42 solar modules — 4,032 modules in all — perched on the side of a hill with the beautiful Rocky Mountains in the background. It’s called the SunMine project and it’s all part of the reinvention of Kimberley, B.C., from mining town to a clean tech, tourism town of the ...

  • Zig–zag transformer for neutral current compensation in an isolated wind energy system

    This paper presents a voltage and frequency controller with neutral current compensation in a stand alone wind energy conversion system (WECS) employing an asynchronous generator. The proposed controller consists of a three leg insulated gate bipolar junction transistor (IGBT)–based voltage source converter and a battery energy storage system (BESS) at its DC bus. The neutral terminal for the ...

  • Solar Energy and Power Importance

    Have you ever wondered why solar energy or power is important? You are not alone in this because it is the common question of all. Before we can understand why solar energy is important we should have a good idea of what solar energy is. Solar energy is produced by the sun. It can be harnessed like any other type of energy and used to ...

  • Solar power generation by photovoltaic technology

    The various forms of solar energy, solar heat, solar photovoltaic, solar thermal electricity, and solar fuels offer a clean, climate-friendly, very abundant and in-exhaustive energy resource to mankind. Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). The research has been under way since the ...

  • Detection and classification of power quality events using multiwavelets

    Wavelet transforms have fundamentally been used to detect the major features of power quality events, as the transforms adapt to dynamic signals and are appropriate for capturing time-localised, short-period phenomena. The multiwavelets technique is proposed here to classify power quality events. This leads to easy extraction of a quality feature set, which is further used for classification and ...

  • 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 ...

  • Political support for nuclear power in Central Europe

    Since the Fukushima nuclear disaster in Japan, nuclear energy has been under increased media scrutiny. The focus is mainly on Germany and the radical transformation of the position on nuclear energy in that country. To understand and potentially predict the development, however, the situation needs to be viewed from a wider Central European perspective. Polarisation of countries' attitudes ...

  • Verification of nuclear power plants safety systems

    Although safety is and has always been the primary objective for the nuclear community, it happens that the established practices for verification of nuclear plants' safety systems fail to provide reliable knowledge. The traditional investigation techniques have proven to be insufficient in their attempts to solve the problems and to prevent new failures. In this paper, difficulties in performing ...

  • A two-stage power electronic interface for fuel cell-based power supply system

    The increasing energy demands, insufficient availability of power generation and increasing global environmental problems, need alternate/green power sources. Among the different green power technologies such as wind power, photovoltaic, gas turbine and fuel cell, the fuel cell-based distributed generation is considered as one of the most promising solutions for stand-alone/grid applications due ...

  • Tritium dispersion simulation in the atmosphere from ANGRA I Nuclear Power Plant

    In this work, we check the ability of an air pollution model to simulate the concentration of radioactive material emitted from the Nuclear Power Plant of Angra dos Reis, Brazil. To achieve this goal, we solve the time-dependent two-dimensional equation by the Generalised Integral Laplace Transform Technique (GILTT) method. The wind field was reconstructed by the MM5 mesoscale model and the ...
