  1. 21. How grid connected solar cells impact on the low voltage grid of Duckarp

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Annelie Engdahl; [2017]
    Keywords : ;

    Abstract : To limit the ongoing climate change and to meet the UN target for an increased temperature of maximum 2 degrees, governments worldwide strive for sustainable and fossil free power generation. Hence, Photovoltaic Solar Cells (PVs) are of great interest. The potential from sun is infinite; the annual solar radiation corresponds to 6. READ MORE

  3. 22. Mitigation of Background Harmonic Amplification at PCC Using Active Filtering of STATCOM

    University essay from KTH/Elkraftteknik

    Author : Luai Malki; [2017]
    Keywords : FACTS; Hybrid-STATCOM; TSC; TSR; VSC; passive filter; active filter; PWM; MMC; passivity; input admittance; resonance; harmonics; ABB;

    Abstract : Shunt compensation devices have been a powerful candidate for expanding the limits of transmission facilities, allowing more active power transport and supporting voltage and overall stability of the network. An example of such devices is the Static Synchronous Compensator (STATCOM) which is based on Voltage Source Converter (VSC) which synthesizes output voltage and current for mainly reactive power compensation.

  4. 23. Application for Wind Farm Integration Complying with the Grid Code by Designing an Outer Control Strategy for the Converter.

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Alexandra Kapidou; [2016]
    Keywords : Wind Farm; STATCOM; Grid Code; Positive and Negative Sequence Current Controller; Reactive Power Compensation;

    Abstract : The continuously increasing energy penetration from wind farms into the grid raises concerns regarding power quality and the stable operation of the power system. The Grid Code´s requirements give strict guidelines for a wind farm´s behaviour under faulty or abnormal operating conditions. READ MORE

  5. 24. Evaluation of two distribution grids in terms of PV penetration limits and effectiveness of reactive power controls

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Leonard Hülsmann; [2016]
    Keywords : ;

    Abstract : The large integration of photovoltaic (PV) systems as well as wind turbines in the distribution grid poses new challenges on various levels. One of them is the increased steady-state voltage in the low voltage (LV) as well as the medium voltage (MV) grid, caused by the distributed generation. READ MORE

  6. 25. Reactive Power Planning with Voltage Stability Constraints for Increasing Cross-Border Transmission Capacity

    University essay from KTH/Elektriska energisystem

    Author : Mana Farrokhseresht; [2015]
    Keywords : ;

    Abstract : In this work Reactive Power Planning (RPP) is studied. It is the method which aims at locating reactive compensators of optimal size at an optimal location in order to achieve or optimize a certain objective. READ MORE
