  • Following the fuel: How portable biomass energy generation may help rural communities

    The forests that surround many of California’s mountain communities tend to have an abundance of woody biomass and a pressing need for thinning to reduce fire danger. Revenue from selling forest residues to biomass power plants could help to support fuel reduction activities, but in many cases the nearest plant is so far away that hauling costs are prohibitive. The remoteness of such ...

  • The Rationale for Accelerating Regionally Focused Climate Intervention Research

    Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

  • Importance of Inspecting Reservoirs

    Inspecting Reservoirs – what is the importance of them, why they are inspected, and how ROVs help pave the way for low-cost, regular maintenance. What is a Reservoir? Deriving from the French word réservoir meaning “storehouse,” a reservoir is exactly that – a storage place for water. More often than not, these bodies of water are ...

  • Hidden failures in electric power systems

    Hidden failures in equipment are those failures which occur at random and that do not lead to any discernible change in the state of the network and, therefore, remain undetected. Although hidden failures can occur in any equipment, the hidden failures in protective equipment have attracted a good deal of attention in recent years. Admittedly these failures are rare but, when the power system is ...

  • Agents controlling the electric power infrastructure

    The electric power grid is evolving from a centrally controlled grid with only a handful of regulated monopolies to an open, liberalised electricity market. In addition, more and more small-scale dispersed generators are deployed in distribution nets. This puts extra stress on the power grid, in an era when electricity is one of the most important commodities for economic, industrial and everyday ...

  • Harmonic assessment of electrical power systems

    Advances in semiconductor technology have resulted in an escalation in the numbers and power ratings of non-linear loads connected to the power system. At all voltage levels, equipment is being installed which generates harmonics. At transmission levels, FACTS devices are being installed for controlling power flow, HVDC links are used to transfer real power between AC systems and large industries ...

  • Electricity trading in Indian restructured power market

    In the past few years, most of the electricity industries around the world have been undergoing a movement from monopoly utilities to restructured competitive electricity markets. At present time, the operation of electricity markets all over the world varies from one country to another. Indian electricity market is trading with power transactions through power exchanges. Practically, Indian ...

  • Power management policies and control of hybrid electric vehicle

    With increasing concern over the environment and ever-stringent emission regulations, the use of hybrid electric vehicle (HEV) is being investigated as an alternative form of transportation. A hybrid vehicle combines the advantages of an electric drive and an internal combustion engine. This paper proposes the necessary hardware and software needed for an effective control of the electrical part ...

  • Online condition monitoring of electrical power system imbalance

    Symmetrical components are of great importance in many applications in electrical power systems, such as power protection and condition monitoring. This paper presents a computer-based algorithm for online symmetrical components estimation. The proposed algorithm uses the samples of the phase variables (currents or voltages) to estimate the magnitude and phase angle of each phase phasor at each ...

  • Benefits of the Best Pressure Washers Powered By Electricity

    Ask any expert about the best pressure washers and they are likely to mention the electric powered versions. Since they run on electricity, the electric-powered ones are highly versatile and ideal for use in almost all settings with reliable electrical supply. The cleaning efficiency of the best pressure washers is measured in terms of their pressure in psi (pounds per square inch) and flow ...

  • Electric vehicles powering communities through natural disasters

    Mass power outages and blackouts have always been of great concern during and after natural disasters. In addition to the devastation that can occur from flooding, collapsed buildings, and disruptions to basic infrastructure, the absence of electricity can shut down basic communications systems, adding to the anxieties of those most critically affected. While much discussion revolves around what ...

  • Policy and economic issues of electrical power and energy systems

    During the last quarter of the 20th century, many developments have served as catalysts for changes in the national energy policies of countries throughout the globe. These catalysts have affected the institutions and energy framework of virtually every country. In the majority of countries, the predominant electricity supply institution is the electric utility monopoly characterised by some ...

  • Electric Power Supply Quality in ship systems: an overview

    Power Supply Quality (PSQ) has become an important concern for ship electric systems. Thus, deviations of voltage from nominal values and wave-shapes could cause several problems onboard. Considering that ship system electrification eventually dominates according to the All Electric Ship concept, PSQ will be a key-factor of the normal operation, survivability and safety aboard. The paper provides ...

  • Electric power systems real-time monitoring and control

    In recent decades, several improvements have been achieved in power system operation and control. The evolution was mainly in the development of computational and communication systems. Both areas allowed the analysis of complex models of power system operation and control that resulted in a more flexible system controlled in almost real-time mode. All these improvements favoured the change of ...

  • Solar thermal power plants for the Spanish electricity market

    Solar thermal power plants are at present the cheapest technology for solar electricity production. At good sites Levelised Electricity Costs (LEC) of 11 Ct/kWh have been achieved in commercially operated power plants. Economy of scale and further technical improvements will reduce the LEC for future projects. On the 27th of March 2004 in Spain the existing feed-in-law has been modified in order ...

  • Ships that harvest electrical power from ocean waves

    Electrical power generation from ocean waves is possible from ships that harvests wave energy through daily trips to offshore locations and that return back to port for the delivery of energy to the grid. Energy is stored locally on the vessel during harvesting phase and placed on the grid during periods of high demand (normally mid-day). Unlike conventional wave-power devices, the ships ...
