  • Ukrenergo review 22-29 september 2017

    We are elaborating the best and the brightest news for you to be in course of the world energy trends.  Right now, you are invited to attend the exhibition of the innovations in the energy sector. 5 modern texts. 5 minutes  of pleasure.

    1. Control center of the future. 

    Siemens and its partner entities have built the world’s first dynamic   grid control center –  the “DynaGridCenter” project. Here, the focus will be on optimizing the management of energy generated from renewable sources and the associated electricity trading environment.
    Siemens grid model transmits measurement data to the control center, where it’s analyzed in real time. The data is based on measurement technology that is already installed in many parts of the grid, but that most control centers are not yet able to make use of.  Phasor Measurement Units (PMUs), for instance, measure the extent and phase angle of current and voltage every 10-20 milliseconds. PMUs in the grid are synchronized to enable measurement values from different transformer substations to be directly compared. 

    Ilmenau University of Technology researchers proved the practical advantages both of the control center and grid model. Just a dream for Ukrenergo operators. Don`t think however we are advertising Siemens.

    1. But first cybersecurity.USA companies spend billions of dollars on cybersecurity. Research firm Zpryme estimates that U.S. utilities will spend$7.25 billion on  grid cybersecurity by 2020.   Cutting edge technologies are essential to help the electricity sector adapt to the evolving cyber threat landscape.   Specific products that could help with cybersecurity on the grid are Siemens’ Ruggedcom Crossbow, Cisco’s 2950 (Aggregator) and Schneider Electric’s Tofino Firewall.   The National Institute of Standards and Technology is conducting investigations.

    The Sierra Nevada Corporation has created a product called Binary Armor that provides bidirectional security for communication layers on the grid. This allows tailored rules to be set for specific messages to enter the network.  It is considered to have no alternatives to the technology.

    1. Energy efficiency is at the forefront. Yes, officially.Renewables serve as the most important drivers of the energy efficiency. Surprise? Actually, not. However IRENA has recently published a report  (https://irenanewsroom.org/2017/08/21/renewables-and-energy-efficiency-a-dynamic-duo/amp/) regarding influence of the renewables both on the energy efficiency and economic growth. Global energy-related CO2 emissions could be reduced 70% by 2050, IRENA finds.  Why? Owing to energy efficiency and electrification growth.

    How come? Renewables. Where can we find such a great amount of “green” generation? IRENA claims it is not a problem at all. Even the USA army is studying about new possibilities of the distributed renewables. Last month Redstone Arsenal installed new 10-MW solar power plants in Alabama. Glittering future. It is vital to keep the pace.

    1. Fill tank with a high quality…seaweeds.Let`s get acquainted with the Department of Energy’s Pacific Northwest National Laboratory in the USA. Recently they have worked out a technology to fill the tanks with the biofuel produced of the seaweed.  The program aims to create tools that enable mass production of marine biomass that can be turned into biofuel and bio-based chemicals.

    DOE estimates the U.S. could produce enough macroalgae to meet about 10 percent of the nation’s annual energy needs for transportation. 
    However, new technologies and innovative engineering approaches are needed to significantly increase production before cars can run on seaweed.

    Projects of the special farms to cultivate the seaweeds are being worked out. Looking forward to new types of fuel at the American gas stations.

    1. Turbines to harness electricity from ocean currents instead of NPPs. Scientists have developed a new turbine that can harness energy from ocean currentsto produce low-cost and sustainable electricity. The technology will protect the shore from erosion as well as generate the electricity. Okitawa Institutes proves using just one per cent of the seashore of mainland Japan can generate about 10 gigawatts of energy, which is equivalent to 10 nuclear power plants. The capacity is comparable to 10 nuclear units!

    It uses submerged turbines anchored to the sea floor through mooring cables that convert the kinetic energy of sustained natural currents in the Kuroshio into usable electricity, which is then delivered by cables to the land. The turbines themselves are built to withstand the forces thrust upon them during harsh wave conditions as well as extreme weather, such as a typhoon. The blade design and materials are inspired by dolphin fins – they are flexible, and thus able to release stress rather than remain rigid and risk breakage. Researchers have completed the first steps of this project and are preparing to install the turbines for their first commercial experiment. Successful completion. Researchers are now looking for the investors for a full energy expansion.
