  1. 1. On Power-system Benefits, Main-circuit Design, and Control of StatComs with Energy Storage

    Författare :Hailian Xie; Hans-Peter Nee; Lennart Ängquist; Timothy Green; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage; Voltage source converter; VSC; Static synchronous compensation; StatCom; Active power compensation; Phase jump; Voltage dip; Weak network; Flux modulation; Deadbeat current control; Transformer saturation; Dual thyristor converter; dc interface; Electrical engineering; Elektroteknik; Electric power engineering; Elkraftteknik;

    Sammanfattning : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. LÄS MER

  2. 2. Voltage Source Converters with Energy Storage Capability

    Författare :Hailian Xie; Hans-Peter Nee; Lennart Ängquist; Ambra Sannino; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Voltage source converter; StatCom; Energy storage; Active power compensation; Phase jump; Voltage dip; VSC; Weak network; Flux modulation; deadbeat control; Electric power engineering; Elkraftteknik;

    Sammanfattning : This project deals with voltage source converters with energy storage capability. The main objective is to study the possible benefits of energy storage to a power system with a VSC as the interface between them. First of all, a converter control system is proposed for a two level VSC. LÄS MER
