  • Fuel Cell Voltage Monitoring Considerations

    Knowing what’s happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltageof each cell in a stack. Although this may sound trivial, it can be more complex and more expensive than it may at first appear due to high voltages, high channel counts,communication types, etc. There ...

  • Voltage Optimisation can improve schools energy efficiency by up to 25%

    Voltage Optimisation is a key component in any energy efficiency programme and could deliver up to 25% savings on electricity bills. In April the registration period for the Carbon Reduction Commitment (CRC) Energy Efficiency Scheme will start again. Local authorities and companies with a portfolio of private schools will face sizeable fines unless they account for their energy use ...

  • Development of modulation strategies for three-phase to two-phase matrix converters

    In this paper, the modulation strategy is developed for three-phase to two-phase matrix converters for synthesising balanced and unbalanced output voltages from balanced and unbalanced input voltages. Reduction of low order input current harmonics with sinusoidal output voltages is achieved by using the proposed switching strategies. The other advantage of the proposed method is the significant ...

  • Power conditioning of an uncontrolled micro-hydroturbine-driven induction generator for distributed generation using a battery energy storage system

    Distributed Generation (DG) and its interconnection to the AC power grid is a relatively new concept. DG employs small generators, which are distributed throughout the power system. The electricity is usually generated by renewable energy sources such as wind, hydro and tidal, which are intermittent in nature. These generators connected to the AC grid may lead to severe power quality problems. ...

  • Design of single–stage three–phase grid–connected photovoltaic system with MPPT and reactive power compensation control

    This paper proposes a single stage three–phase grid–connected photovoltaic (PV) system topology, it being simpler and more efficient. This includes the modelling of PV module and the power conditioning unit interfacing the PV to the utility grid with proper power flow control. The output of the PV panel is connected to the DC–side of the voltage source inverter for interfacing to the grid. The ...

  • Integration of solar photovoltaic (PV) to LV distribution network: a case study

    The development of renewable energy sources will increase the amount of generation connected to distribution networks. The main advantages are that optimally located distributed generation resources can reduce or postpone the need for investment in the transmission and distribution infrastructure; transmission and distribution losses are reduced as well as improvement in power quality and system ...

  • A novel harmonic mitigator-based 12-pulse rectification for vector-controlled induction motor drives

    This paper presents an optimised 12-pulse autotransformer-based AC–DC converter with reduced kVA magnetics for reducing the harmonic distortion in AC mains current in a vector-controlled induction motor drive (VCIMD). The proposed AC–DC converter results in elimination of fifth, seventh and 11th harmonics in the supply current. The proposed system consists of an autotransformer and a tuned ...

  • How clean energy can power Parking lot lights

    Many cities have now opted to go green with parking lot lighting because it helps in a tight budget while also remaining environmentally sustainable. The use of green energy power through solar has the advantage of saving energy costs and can help in the reduction of carbon emissions. Energy efficiency is very important for any parking lot because there is a need to find long term solutions that ...

  • Energy savings: VFD versus CSV case study

    The two most common ways to produce constant pressure are Variable Frequency Drives or VFD’s, and Cycle Stop Valves or CSV’s. The end result is the same in that the system sees a steady or constant pressure, as the flow rates required vary from small to large. However, these two systems control the pump in completely different ways. Variable Frequency Drives or ...

  • Smarter grids, appliances, and consumers

    More and more utilities are beginning to realize that building large power plants just to handle peak daily and seasonal demand is a very costly way of managing an electricity system. Existing electricity grids are typically a patchwork of local grids that are simultaneously inefficient, wasteful, and dysfunctional in that they often are unable, for example, to move electricity surpluses to areas ...

  • Water vapour permeation measurement for PV Solar Cell packaging

    With fears of carbon dioxide causing global warming and diminishing supplies of fossil fuels, a looming energy crisis is affecting all countries.  As a consequence, a great deal of world-wide effort is going into the development of alternative energy technologies.  At present, wind, hydro and geothermal are becoming well established with more niche roles for tidal and solar. The latter ...

  • Offshore Wind Versus Solar in the Eastern US: An Unexpected Rivalry

    Less than a decade ago, offshore wind energy and solar PV were similarly priced energy sources. Unsubsidized installed costs for both exceeded $5 per watt, or more than double that for land-based wind. Despite their cost, both technologies were seen as the best hopes for supplying urban centers with green power, especially in the BOSNYWASH (Boston-New York-Washington, DC) corridor of the eastern ...

  • The Emerging Power of Microgrids

    Over many decades, the centralized power grid — a one-way flow of electricity, generated by large, remote power plants and distributed over miles of transmission lines to homes and businesses — succeeded in delivering electricity across continents to billions. But in recent years the system’s shortcomings have become increasingly ...
