  • The CBR-PNN approach to real-time voltage security assessment of power systems

    This paper presents the Case-based Reasoning (CBR) technique, a novel approach to voltage security assessment of power system in a real-time environment. The Probabilistic Neural Network (PNN) is used for determining the solution to a new case, using the old cases from the case base of the CBR system. A feature selection technique based on the information gained has been employed to identify the ...

  • Energy Management Contract

    1. Introduction Energy management contract (EMC) is a new market-oriented energy saving mechanism. It is not to market a product or a technology, but a financial management method to reduce the energy costs. EMC companies provide the customers with a complete set of energy saving services, including energy auditing, project design & financing, engineering construction, ...

  • Control and small-signal analysis of battery and supercapacitor hybrid energy storage systems

    This paper is devoted to control strategies for an active battery and supercapacitor hybrid energy storage system using the master-slave control scheme, where the charging and discharging currents of the supercapacitor are dependent on that of battery and the current sharing ratio depends upon the load conditions. A small-signal model is proposed, which considers the variations in the currents of ...

  • Why the fossil-fuelled reactor fleet in France will not be affected by an evolution of the wind power capacity

    Today's power electronics can confer high-performance adjustment capabilities on any technological object, including the frequency-power and voltage tuning of modern, synchronous-type wind turbines. However, this will not enable such devices to steadily produce electric power from an uncontrolled mechanical energy. Thus they cannot be considered independent generation units: the need to ...

  • Comparative performance of BESS and SMES in distribution network to improve power quality

    The FACTS devices, like STATCOM, are becoming a part of the modern power system to improve the power system operation and power quality problems. Integrating the battery energy storage system (BESS)/superconducting magnetic energy storage (SMES) across the dc bus of the STATCOM can provide effective modulation of the real and reactive power. The dynamics of each of these differ because of their ...

  • Risk assessment of catastrophic failures in electric power systems

    The declining reliability of the US electric power system is raising major concerns among both politicians and power engineers in the USA. One of the reasons put forward by the North Electric Reliability Council (NERC) is the detrimental role played by the protection systems during large disturbances, which tend to help the perturbations to propagate through over-tripping of fault free system ...

  • Installing an ESD LH1000 A Micro hydro Evolution Article describing the installation of an ESD LH1000 low head machine

    Every morning, before brushing teeth or having a look at the weather outside our Victoria, Australia, off-grid home, my wife Carrie or I pad downstairs to the battery room to check the meters that monitor our electrical system. The reading determines whether we use the propane stove or the electric jug to heat water for our tea. Since our microhydro plant upgrade, it’s usually the jug. ...

  • Spi-Sun simulator sets the standard

    Solar Simulators are critical to the industry testing photovoltaic modules featuring light sources that closely match the solar spectrum. Spire’s simulators can test the full range of solar modules – including crystalline or thin film. The importance of solar simulation is clear – solar modules must be tested under a standard set of conditions to assure consistency of results. ...

  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...

  • Beyond the Tesla Powerwall: How energy storage is shaping up in Ontario - How energy storage changes everything

    There are not many entrepreneurs who can command a room like Elon Musk. When he stepped onto a stage in May to unveil the Powerwall the audience oohed and ahhed and dutifully pre-ordered more than 38,000 of Tesla’s new home battery systems. And while Tesla gets the headlines other energy storage ...

  • After Record 2012, World Wind Power Set to Top 300,000 Megawatts in 2013

    Even amid policy uncertainty in major wind power markets, wind developers still managed to set a new record for installations in 2012, with 44,000 megawatts of new wind capacity worldwide. With total capacity exceeding 280,000 megawatts, wind farms generate carbon-free electricity in more than 80 countries, 24 of which have at least 1,000 megawatts. At the European level of consumption, the ...

  • Minimum Total Harmonic Distortion on board Scandlines New Hybrid Ferries Berlin & Copenhagen - Case Study

    In 2016, Scandlines inaugurated two new hybrid ferries for the Rostock-Gedser route. In order to improve the power quality, Scandlines installed active filters on board M/V Berlin and M/V Copenhagen. Before commissioning, Scandlines’ new hybrid ferries had a power quality of THDV 15%. In order for the ferries to go into operation, the power quality had to be reduced to below 8 ...

  • Offshore Wind Development Picking Up Pace

    Wind power is the world’s leading source of renewable electricity, excluding hydropower, with 238,000 megawatts of capacity installed at the start of 2012. Thus far, almost all of this wind power has been tapped on land; worldwide just 4,600 megawatts of offshore wind farms were operating as of mid-2012. Offshore wind capacity is growing quickly, however, expanding nearly six-fold ...

  • 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 ...
