  1. 1. A Computational Framework for Control of Machining System Capability From Formulation to Implementation

    Author : Andreas Archenti; Cornel Mihai Nicolescu; Mamoru Mitsuishi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining system; Stability; Statistical Dynamics; Elastic Linked System ELS ; Operational Dynamic Parameters ODP ; Loaded Double Ball Bar LDBB ; Virtual Machining System Engine VMSE ; Contactless Excitation and Response System CERS .; SRA - Production; SRA - Produktion;

    Abstract : Comprehensive knowledge and information about the static and dynamic behaviour of machine tools, cutting processes and their interaction is essential for machining system design, simulation, control and robust operation in safe conditions. The very complex system of a machine tool, fixture and cutting tools during the machining of a part is almost impossible to model analytically with sufficient accuracy. READ MORE

  2. 2. Wind Power - Added Value for Network Operation

    Author : Nayeem Ullah; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; torsional oscillation; reactive power ancillary service; voltage stability; power system simulator.; STATCOM; non-minimum phase system; Variable speed wind turbine; frequency control; sensitivity analysis; transient stability; small-signal stability;

    Abstract : This dissertation deals with the investigation on different value added properties of variable speed wind turbines (VSWT) that stem from the flexible controllability of converter interfaced wind turbines (WT). Improvements in voltage and transient stability of a nearby grid, small-signal stability improvement on the power system, frequency control support for the network operation, as well as thetechnical and the economic issues related to the reactive power ancillary service provision, are among the issues covered.

  3. 3. Expansion Governance of the Integrated North Seas Offshore Grid

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : João Gorenstein Dedecca; Paulien M. Herder; Rudi A. Hakvoort; Amineh Ghorbani; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Union; expansion planning; governance; HVDC; myopic optimization; North Seas; offshore grid; offshore wind; simulation;

    Abstract : The expansion of offshore power transmission and generation in the North Seas of Europe is accelerating rapidly. This is due to several drivers, including the decarbonization and reform of the European power system, and innovations in offshore wind and high-voltage direct current transmission. READ MORE
