  2. 1. Concurrent Engineering of Small Satellites using Hardware-in-the-loop Simulations

    Author : Cristóbal Nieto-Peroy; Mathias Milz; Élcio Jeronimo de Oliviera; Giovanni Palmerini; Sergio Montenegro; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concurrent Engineering; Hardware-in-the-loop Simulation; Small Satellite; CubeSat; Nanosatellite; Test-driven Development; Behavior-driven Development; Frictionless Platform; Floating Platform; Onboard space systems; Rymdtekniska system;

    Abstract : The miniaturization of spacecraft has brough the possibility of conducting space missions to a vast portion of private enterprises and scientific institutions. The inaccessibility of modest developers to the resources that governmental agencies and primary contractors utilize to develop conventional satellites has not been an obstacle for them to apply different, more agile and risk-seeking approaches.

  4. 2. Design, Modelling and Verification of Distributed Electric Drivetrain

    Author : Nimananda Sharma; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric vehicles; system modelling; mechanical-hardware-in-the-loop; real-time modelling; power-hardware-in-the-loop; Distributed drivetrain;

    Abstract : The electric drivetrain in a battery electric vehicle (BEVs) consists of an electric machine, an inverter, and a transmission. The drivetrain topology of available BEVs, e.g., Nissan Leaf, is centralized with a single electric drivetrain used to propel the vehicle. READ MORE

  5. 3. Synchrophasor Applications and their Vulnerability to Time Synchronization Impairment

    Author : Muhammad Shoaib Almas; Luigi Vanfretti; Mario Paolone; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hardware-in-the-loop; phasor measurement units; real-time simulation; time synchronization; wide-area monitoring protection and control.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Recent years have seen the significance of utilizing time-synchronized, high resolution measurements from phasor measurement units (PMUs) to develop and implement wide-area monitoring, protection and control (WAMPAC) systems. WAMPAC systems aim to provide holistic view of the power system and enable detection and control of certain power system phenomena to enhance reliability and integrity of the grid. READ MORE

  6. 4. Synchrophasor based Steady State Model Synthesis of Active Distribution Networks

    Author : Farhan Mahmood; Luigi Vanfretti; Francisco Gonzalez-Longatt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active distribution networks; phasor measurement units; model synthesis; real-time simulation; hardware-in-the-loop.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : With the increased penetration of distributed energy resources (DERs) at lower voltage levels, distribution networks (DNs) are being transformed into active grids. This has led to a paradigm shift in the operation, planning and control of DNs. READ MORE

  7. 5. Inverter Design for SiC-based Electric Drive Systems with Optimal Redundant States Control of Space Vector Modulation

    Author : Georgios Mademlis; Chalmers tekniska högskola; []
