  1. 1. Centralised MPC for Long-term Voltage Stability Control of Power System

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Johan Hallberg; [2023]
    Nyckelord :Voltage stability; Model predictive control; Tap-changing transformer; Capacitor bank; Spänningsstabilitet; Model prediktiv reglering; Lindningskopplare; Kondensatorbank;

    Sammanfattning : In a power system it is important to keep voltages at specific levels at network buses. Deviations from that can lead to reduced efficiency of transferred power or, in more severe cases, widespread power outages affecting large parts of society. There exists a variety of power system devices that have the ability to regulate the voltage levels. LÄS MER

  3. 2. Evaluation of a Centralized Substation Protection and Control System for HV/MV Substation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Jens Ljungberg; [2018]
    Nyckelord :Substation system architecture; Centralized Protection and Control; Voltage regulation;

    Sammanfattning : Today, conventional substation protection and control systems are of a widely distributed character. One substation can easily have as many as 50 data processing points that all perform similar algorithms on voltage and current data. LÄS MER

  4. 3. Reactive Power Control for Voltage Management

    Master-uppsats, Uppsala universitet/Elektricitetslära

    Författare :MD. Shakib Hasan; [2017]
    Nyckelord :STATCOM; PV inverters; LV and MV distribution network;

    Sammanfattning : This thesis presents methods for voltage management in distribution systems with high photovoltaic (PV) power production. The high PV penetration leads to both new challenges such as voltage profile violation and reverse power flow, and also new opportunities. LÄS MER

  5. 4. Analys av reaktiv effektinmatning till överliggande nät samt optimal kondensatordrift

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Göran Sundström; [2017]
    Nyckelord :Reactive power; Input; Compensation; Capacitive; Inductive; Reactor; Capacitor; Operating capacitors; Operation of capacitors; Operating capacitor banks; Operation of capacitor banks; Static VAr-compensator; SVC; STATCOM; Reaktiv effekt; Inmatning; Kompensering; Kapacitiv; Induktiv; Reaktor; Kondensator; Kondensatordrift; Statisk VAr-kompensator; SVC; STATCOM;

    Sammanfattning : Bakgrunden till detta projekt är att Vattenfall Eldistribution AB (nedan kallat Vattenfall) kommer att införa ett avgiftssystem för inmatning av reaktiv effekt till sitt elnät. Avgiften införs till följd av problem på elnätet som orsakas av reaktiv effekt. LÄS MER

  7. 5. MODELING AND SIMULATION OF A HYBRID WIND-DIESEL MICROGRID

    Master-uppsats, KTH/Elektriska energisystem

    Författare :Vincent Friedel; [2009]
    Nyckelord :Power Systems; Hybrid microgrid; Wind-Diesel system; PSCAD modeling;

    Sammanfattning : Some communities in remote locations with high wind velocities and an unreliable utility supply, will typically install small diesel powered generators and wind generators to form a microgrid. Over the past few years, microgrid projects have been developed in many parts of the world, and commercial solutions have started to appear. LÄS MER
