  1. 1. Battery energy storage design and operation in an HVDC-system with WPP clusters

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Harald Åkesson; [2019]
    Keywords : BESS; Energy storage; State of charge; Windpower; HVDC; Technology and Engineering;

    Abstract : The electricity sector is in the beginning of a large shift from centralized dispatchable production to distributed variable production. With this necessary change, new challenges arise. One crucial challenge is related to upholding the system balance in the power grid. READ MORE

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

    University essay from Uppsala universitet/Elektricitetslära

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

    Abstract : 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. READ MORE

  4. 3. Operation and Control of HVDC Grids

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Adam Bianchi; Gabriel Nylander; [2018]
    Keywords : HVDC; grid control strategies; converter control strategies; fault simulation; HVDC; nätkontrollstrategier; omvandlarkontrollstrategier; felsimluering;

    Abstract : Meshed high-voltage direct current grids are becoming an increasingly important technology for integrating renewable energies into the power system. To control the grids in the best possible way, optimal converter and grid control strategies are needed. READ MORE

  5. 4. 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

  6. 5. Decentralized Model Predictive Controlfor smart grid applications

    University essay from KTH/Reglerteknik

    Author : Phillipp Heer; [2013]
    Keywords : ;

    Abstract : This thesis focuses on a model predictive control scheme which allows organizing the power production of power plants in a decentralized fashion. That way a less computationally demanding control scheme can be applied to control the frequency at each power plant without a governing, high level controller for the whole power grid. READ MORE
