  1. 1. The role of location of low inertia in power systems

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Bashar Alahmad; [2021]
    Nyckelord :Low inertia; Frequency stability; Rotor-angle stability; Nordic 32; Kundur; PowerFactory; Small-signal stability; Inter-area oscillation; Rate of Change of Frequency.;

    Sammanfattning : The plans to reduce the energy-related greenhouse gas emissions stimulate the deployment of electronically interfaced renewable resources. The increased penetration of such intermittent sources together with phasing conventional power plants out and the installation of High Voltage Direct Current (HVDC) links for long-distance more efficient transmission, reduces the stored inertia in any electrical grid.

  3. 2. Investigation of Frequency Containment Reserves With Inertial Response and Batteries

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

    Författare :Hashem Ghasemi; Jakob Melki; [2019]
    Nyckelord :Frequency Containment Reserves; Inertial Response; Instantaneous Frequency Deviation; Battery Energy Storage System;

    Sammanfattning : The rise of Renewable Energy Sources (RES) such as wind and solar power, creates new challenges for electric power systems. One of these challenges occur in Frequency Containment Reserves (FCR) on power system because of decreasing system inertia from RES. LÄS MER

  4. 3. Decentralized Secondary Frequency Control in an Optimized Diesel PV Hybrid System

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

    Författare :Alice Vieira Turnell; [2018]
    Nyckelord :Solar photovoltaic; frequency stability; decentralized secondary frequency control; reserve allocation; hybrid system; island system; HOMER; PowerFactory; Solceller; frekvensstabilitet; decentraliserad sekundär frekvenskontroll; reservallokering; hybridsystem; ösystem; HOMER; PowerFactory;

    Sammanfattning : This research argues that a diesel-based isolated electrical system can be optimized byintegrating a high share of solar photovoltaic (PV) generation and that the frequencystability of such system can be improved by including the PV participation in frequencyregulation. A case study is developed in order to explore an island’s expansion of theinstalled generating capacity and its optimization. LÄS MER

  5. 4. Design and Implementation of a 2-Channel High Precision and High Speed Digitizing system

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Albert Llimós Muntal; [2016]
    Nyckelord :Analog; Digital; ADC; Digitizing; data acquisition; two channel; precision; resolution; speed; Technology and Engineering;

    Sammanfattning : Recently, new spectroscopic techniques have been developed such as photocurrent detected two-dimensional spectroscopy [1], which measure the response from a sample that is excited by a high intensity laser pulses. The responses are linear and nonlinear signals that have very different amplitudes; the linear signal can be from 103 to 105 times larger than the nonlinear signal. LÄS MER

  7. 5. Fördelning av energikostnader på flera tågoperatörer

    L2-uppsats, KTH/Elkraftteknik

    Författare :Marcus Wik; [1994]
    Nyckelord :;

    Sammanfattning : Enligt riksdagsbeslut skall fler företag än SJ få möjlighet att bedriva järnvägstrafik. Hur skall då Banverkets energikostnader för kontaktledningsnätet fördelas mellan de olika trafikerande före­tagen? Individuella mätningar på järnvägsfordonen kan vara ett sätt att skapa ett underlag för hur energikostnadema skall fördelas. LÄS MER
