  1. 1. Evaluating Security Mechanisms of Substation Automation Systems

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

    Author : Ziyang Zhou; [2023]
    Keywords : Substation automation system; Threat modeling; Meta attack language; Stationsautomationssystem; Hotmodellering; Meta attack language;

    Abstract : Substations are important components for transforming voltage and distributing power in electrical infrastructure. Modern substations are usually automated by substation automation systems, which offload the work of operators and reduce potential human error. READ MORE

  3. 2. Communication Interfaces for Mobile Battery Energy Storage Applications

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

    Keywords : BESS; DER; Smart Grid; IEC 61850; Communication Protocol; Flexible Grid; BESS; DER; Smarta nät; IEC 61850; Kommunikationsprotokoll; Flexibelt nät;

    Abstract : In the midst of the green energy transition, the need for flexible grid solutions is growing. One of the most desired and suitable flexible solutions are Battery Energy Storage Systems (BESS), in both stationary and mobile applications. READ MORE

  4. 3. Dynamic Virtual Admittance Control Hardware-In-The-Loop Real-Time Simulation

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

    Author : Damien Gadou-Sanyal; [2020]
    Keywords : ;

    Abstract : To enhance the transient stability and the power oscillation damping of the powergrid, supplementary controllers can be applied to the embedded point-to-point High-Voltage Direct Current (HVDC) links. The work presented in this report aimed tovalidate the Dynamic Virtual Admittance Control (DVAC) designed in SuperGridInstitute, in Software- and Hardware-In-The-Loop (SIL and HIL) simulations.

  5. 4. Power System Protection Modelling with IEC 61850 and IEC 61499

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

    Author : Francisco De Lima; [2019]
    Keywords : ;

    Abstract : The nature of the power system is changing; what was once a clearlydened generation-transmission-distribution-consumer power ow is nowshifting towards a distributed infrastructure, with great amounts of variablerenewable sources in the system. The penetration of alternative energieslike solar and wind have represented a game changer for the electricpower industry, diminishing the traditional dominance of fossil fuel basedsources, and moving towards a more renewable mixture.

  6. 5. Automatic post-fault analysis based on disturbance data stored in substation devices : Approach towards the preventive maintenance

    University essay from KTH/Hälsoinformatik och logistik

    Author : Riad Yalda; Miroslav Urosevic; [2019]
    Keywords : COMTRADE file; preventive maintenance; relay protection; automatic post-fault analysis; IEC 61850; wavelet transform.; COMTRADE filer; förebyggande underhåll; reläskydd; automatisk efterfelsanalys; IEC 61850; wavelettransform.;

    Abstract : This report studies the possibilities of minimizing unplanned maintenance work and improving the availability of power supply by enabling preventive maintenance in power systems, without having to make additional investments in the existing systems. This was done using information from COMTRADE files (disturbance recording files) that are created in the event of a fault in the power system. READ MORE
