  1. 1. Centralised MPC for Long-term Voltage Stability Control of Power System

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Johan Hallberg; [2023]
    Keywords : Voltage stability; Model predictive control; Tap-changing transformer; Capacitor bank; Spänningsstabilitet; Model prediktiv reglering; Lindningskopplare; Kondensatorbank;

    Abstract : In a power system it is important to keep voltages at specific levels at network buses. Deviations from that can lead to reduced efficiency of transferred power or, in more severe cases, widespread power outages affecting large parts of society. There exists a variety of power system devices that have the ability to regulate the voltage levels. READ MORE

  5. 4. Design of the model Community to Electric Vehicle to Community (C2V2C) for increased resilience and network friendliness in photovoltaic energy-sharing building communities

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Edgar Mauricio Ocampo Alvarez; [2022]
    Keywords : C2V2C; Photovoltaic; Coordinated Control; Electric Vehicle; Electromobility; Power Balance;

    Abstract : Both the solar photovoltaic (PV) installation and electric vehicles (EVs) deployment are increasing significantly in Sweden. With the large-scale integration of PV and EVs, problems such as the voltage deviations and overloading of components can arise, since the existing distribution grids are not designed to host the large shares of new EV loads and the intermittent PV power feed-in.
