  1. 1. Optimal Day-Ahead Scheduling and Bidding Strategy of Risk-Averse Electric Vehicle Aggregator : A Case Study of the Nordic Energy and Frequency Containment Reserve Markets

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jacob Dalton; [2018]
    Keywords : ;

    Abstract : The Nordic synchronous grid is facing a number of challenges. The ongoingphaseout of synchronous generation coupled with increased penetration ofintermittent renewable generation is leading to reduced system inertia. READ MORE

  2. 2. Microgrid Safety and Protection Strategies

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Aryudha Hartono; [2018]
    Keywords : IB-RES; grid-connected mode; islanded mode; short circuit; IED; directional zero and negative sequence current protection; unbalanced load flow; protection coordination; fault ride-through;

    Abstract : One of the challenging issues with the Microgrid is that the bidirectional power flow providedby the distributed generator (DG) which modify the fault current level. Furthermore, theinverter based-renewable energy source (IB-RES) limits the total fault current contributionto the grid due to its thermal capability. READ MORE

  3. 3. A micro-CT investigation of density changes in pressboard due to compression

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Johan Stjärnesund; [2018]
    Keywords : Micro computed tomography; μCT; pressboard; density; densification;

    Abstract : Pressboard, a high-density cellulose-based product, is used both as load bearing structures and dielectric insulation in oil-filled power transformers. During transformer operation, mechanical forces and vibrations are applied on the material. READ MORE

  4. 4. Integrated generator for use in aircraft engines

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Fredrik Andersson; [2018]
    Keywords : Integrated generator; aircraft engine; generator; aircraft generator; Technology and Engineering;

    Abstract : In this paper the use of integrated generators for airplane engines is examined. In order to accomplish this goal a combination of MatLab with FEMM and ANSYS Maxwell is used to make incrementally more and more detailed analysis of the integrated generator concept. READ MORE

  5. 5. AA-CAES physical modelling: integration of a 1D TES code and plant performance analysis

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Luca Santo; [2018]
    Keywords : energy storage; balancing; grid; AA-CAES; CAES; peaks; energy scenarios; s-function; simulink; simscape; matlab; C ; TES; thermal energy storage; dumping; demand side management; power systems; turbine; compressor; cavern; CAS; compressed air; heat exchange;

    Abstract : The focus of this thesis work was the development of an approachto couple a previosly existing Thermal Energy Storage (TES) modelwritten in C++ with a Simulink/Simscape plant model to simulate anAdvanced Adiabatic Compressed Air Energy Storage (AA-CAES) plant.After the creation and validation of such tool, the complete modelwas used to run simulations, with the aim of assessing the AA-CAESplant's performance under multiple patterns of charge anddischarge.
