  1. 1. The Operational Strategy Optimization of Distributed Energy System Based on MATLAB : A case study in Northeast China

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yujun Han; [2023]
    Keywords : Distributed Energy System; CCHP; operational strategy; Distribuerat energisystem; CCHP; operativ strategi;

    Abstract : China is the largest energy consumer worldwide, with a fast-growing rate. But the energy and environmental problems brought by its unbalanced energy structure and low energy efficiency restrict the sustainable development of China. The Distributed Energy System (DES) is one of the internationally recognized solutions to the problems. READ MORE

  3. 2. System impact of micro-production

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Annie Haraldsson; [2023]
    Keywords : Fault ride through; LVRT; micro-production; solar production; photovoltaics; fault simulation; network modeling; power system disturbances; PMU-registrations; fault analysis; Technology and Engineering;

    Abstract : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG.

  5. 4. Sizing and dispatch optimization for PV BESS systems in specific markets

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Natalia Triunfo; [2023]
    Keywords : ;

    Abstract : The consistent rise in electricity demand, coupled with the degradation of our planet's resources, has driven the growth of renewable energy. Various strategies are being implemented to facilitate the transition to renewable sources, encompassing initiatives such as increasing transmission lines, developing energy storage technologies, or combining different renewable energies.

  6. 5. Extension of low voltage distribution by pure DC or mixed AC/DC parts for integration of solar PV and EV charging

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

    Author : Sofie Jiang; [2022]
    Keywords : LVDC; LVAC; solar PV system; electric vehicle charging station; IKN-regulation; distribution system; RES integration; LVDC; LVAC; solceller; elfordon; laddstolpar; IKN-regelverk; distributionsnät; förnyelsebara energikällor;

    Abstract : This work examines the local distribution system in two residential areas in two Swedish towns, Oxelösund and Karlskrona, and studies how integration of PV systems and electric vehicle (EV) charging stations (CS) will affect the present distribution system. The research questions focus on the economic feasibility of a LVDC system, how it compares to a traditional LVAC (low voltage alternating current) system from an economic and technical perspective, and the possibilities a LVDC system brings to other DC component applications.
