Analysis of micro cogeneration systems in the context of smart energy grids

 

Micro cogeneration (micro-CHP) is a technology that generates heat and electricity in the same time for residential buildings.  The Micro cogeneration systems are an advantageous means of producing decentralized green energy and offers significant benefits: reduced primary energy consumptions, reduced CO2 emissions, avoidance of central plant and network construction. In the context of Smart Energy Grids, Micro-CHP technology can contribute to the transition of the traditionally centralized energy supply system towards a more sustainable system. The aim of this paper is to give an overview on micro-CHP systems and technologies in the context of Smart Energy Grids and to present recent R&D activities carried out by INSA Strasbourg ICUBE. Furthermore, the present paper examines a variety of possible micro-cogeneration technologies to be coupled with an electrical vehicle in the context of energy transition. A numerical tool has been developed to simulate the interactions between micro combined heat and power systems, a residential building and the electric grid. Results show the relevance of the coupling between electric vehicles and micro cogeneration electricity production in the context of energy transition.

Big sensors for the smallest particles - studying Big Bang matter at the Large Hadron Collider

 

Collisions of nuclei at high energies produce deconfined quark-gluon matter, a state of matter which prevailed in our Universe in its first 10 microseconds of existence. I will discuss how we study the properties of this state of matter and its still-mysterious transition to hadrons with confined quarks and gluons, like the common protons and neutrons which make up the atomic nuclei. We employ the Large Hadron Collider at CERN, where we investigate billions of collisions using large, very sensitive and very fast detectors to measure in 3D the trajectories of the thousands of particles produced in such collisions and also identify them. This information allows us to reconstruct the state of deconfined matter and determine quantitatively its properties, for instance that the quarks and gluons form hadrons at a temperature of about 100000 larger than that in the center of our sun.

New trends for active distribution grids

 

Many drivers are determining continuous changes in the structure and operation of distribution grids. In addition to the now long-lasting effects introduced by the smart grid paradigm, a number of new trends are emerging. Relevant aspects include the impact of the diffusion of renewable energy sources in the operation and economics of distribution systems and microgrids, the development of local solutions for the generation, management and storage of energy at small- and micro-scale, the interactions among different energy networks, the increasing attention towards grid-side and demand-side flexibility, the provision of grid services, as well as the evolutions in progress to establish local energy markets and energy communities. The presentation discusses the key points of the energy transition seen from the points of view of the distribution side and of the local energy system manager at the prosumer side.

LEDs and Measurements – How Much Light Source Influence the Measurement Results

 

When measuring the illuminance or luminance under the light source with a photometer one should always consider the conditions at which the photometer was calibrated. Almost all photometers are today still calibrated with the CIE standard illuminants A, which is usually realized by incandescent lamp at color temperature of 2865 K. On the other hand, the measured light source in most cases is not an incandescent lamp but fluorescent lamp or HID lamp or today more and more LED lamp. For such cases the ISO/CIE 19476:2014 standard with title “Characterization of the Performance of Illuminance Meters and Luminance Meters” recommends use of spectral mismatch correction factors to correct the results. Unfortunately, the spectral mismatch correction factors are difficult to calculate if one does not know the measured spectrum and the spectral responsivity of the used instrument. Not considering the spectral mismatch correction factor will result in larger measurement error as the measurement uncertainty might be rather high. The main question of the presented research is so how large the measurement uncertainty might be when measuring the illuminance under different light sources with a lux meter of class C and no mismatch correction factor is applied
