  1. 11. Solar Tent : A Photovoltaic Generator Model for a Flexible Fabric with Inbuilt Cells

    University essay from Högskolan Dalarna/Energiteknik

    Author : Ali Manhal; Tammam M. Ali; [2019]
    Keywords : Solar tent; PV system; refugee camp; PV monitoring system; and flexible PV modules;

    Abstract : Natural disasters and conflicts in many different parts of the world force thousands of people to get displaced from their homes and live in refugee camps temporarily or permanently. For refugee families, lack of energy access has great impact on their lives. READ MORE

  3. 12. Optimization of a grid connected residential battery storage system in Sweden : Home Energy Management System Approach

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Fabrizio Gomez; [2018]
    Keywords : ;

    Abstract : The market for energy production has experienced relevant changes to reach more sustainable characteristics, during the last two decades. In this context, residential photovoltaic (PV) system has gained popularity as a practical and profitable alternative to complement the electric supply from the grid. READ MORE

  4. 13. On the use of integer and fractional flexible Fourier form Dickey-Fuller unit root tests

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Marcus Nordström; [2018]
    Keywords : Fractional frequency flexible Fourier form; Unit root test; Structural break; Smooth break; Nonlinear trend; Business and Economics;

    Abstract : In this paper we propose the use of a new set of conservative critical values for the flexible Fourier form Dickey-Fuller unit root test when the Fourier frequency is estimated. We consider both the integer frequency and the fractional frequency version of the test and investigate their size and power properties. READ MORE

  5. 14. Grid impact study of frequency regulation with EVs

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Emma Blomgren; [2018]
    Keywords : Electric vehicles EVs ; grid impact; ancillary services; frequency regulation; FCR-N; vehicle-to-grid V2G ; voltage; reactive power; load profile; Technology and Engineering;

    Abstract : The ongoing grid paradigm shift has resulted in synchronous generators currently being phased out. As the generators have been providing ancillary services, such as frequency control regulation, this means that new technologies to perform ancillary services need to be developed and evaluated.

  6. 15. A digital image correlation method for detection of fatigue cracks in non-load carrying T-joints

    University essay from KTH/Lättkonstruktioner

    Author : Björn Jonsson; [2018]
    Keywords : ;

    Abstract : In dynamical loaded welded structures fatigue life is often a limiting factor. Common practise is to reduce nominal stress by increased material thickness which leads to oversized, heavy structures. Those practises are replaced by improvement of production and designingtechniques to utilize better properties of high strength steels. READ MORE
