  1. 16. The Emergence and Compensation of Reactive Power in the North Western Province of Zambia

    University essay from Uppsala universitet/Elektricitetslära

    Author : Matthew Koenig-Barron; [2017]
    Keywords : reactive compensation; Zambia; transformer; powerworld; shunt reactor; long line model;

    Abstract : The design of a transmission project is as varied in the factors that affect it as the people to which the project supplies electricity. This thesis focuses on the theoretical considerations in the design process that affect the emergence of reactive power in a system and how reactive compensation is achieved. READ MORE

  3. 17. Reactive Power Control for Voltage Management

    University essay from Uppsala universitet/Elektricitetslära

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

    Abstract : 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. READ MORE

  4. 18. Benchmarking of Smart Grid Conceptsin Low-Voltage Distribution Grids

    University essay from KTH/Kraft- och värmeteknologi

    Author : Odilia Bertetti; [2017]
    Keywords : Smart Grid; Grid Integration; Distributed Generation; Electric Vehicles; Photovoltaic; Battery Storage; Heat Pump; Flexibility; DigSILENT PowerFactory.; Smart Grid; Nätintegration; Distribuerad Generation; Elfordon; Solceller; Batterilagring; Värmepump; Flexibilitet; DigSILENT PowerFactory;

    Abstract : Due to increasing penetration of decentralized variable renewable energy generators and the increasing demand of electrical power due to the electrification of the heat and transport sectors, low voltage grids are facing critical problems. Deviation of the permitted voltage range and local overloads of the grid equipment, are the two main issues that are compromising a smooth distribution grid operation. READ MORE

  5. 19. An MMC-based topology with Dual-Active-Bridge power channels for load balancing in 50 Hz-railway applications

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

    Author : Andreas Zafeiropoluos; [2017]
    Keywords : Power electronics; STATCOM; MMC; power channel; power quality; negativesequence compensation; high-speed trains;

    Abstract : The purpose of this thesis report is to investigate challenges related to railway electrification. Inac-railway systems, trains are most often single-phase loads, which can create significantunbalances in the grid, when fed directly from two adjacent phases. READ MORE

  6. 20. 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
