  1. 1. Renewable Microgrid : Design and modelling of a potential microgrid by analyzing the renewable resource at island Östergarnsholm to supply the inhabitants of Herrvik with electricity and fresh drinking water

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Noor E Hira Gilani; [2021]
    Keywords : Renewable microgrid; Östergarnsholm; Herrvik; Islanded microgrid;

    Abstract : This project is aimed at developing a model for an off-grid microgrid by studying the wind and solar resource at Östergarnsholm, an island to the east of Gotland, Sweden. For the required consumption, a study and analysis of Herrvik’s local demand has been made which is a village close to the island and the possibility for implementing the microgrid to supply electricity to the inhabitants of Herrvik has been examined.

  3. 2. Operation of battery energy storage system for frequency control of hydropower operated in island mode

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Amanda Hallblad; [2020]
    Keywords : Battery energy storage system BESS ; hydropower; microgrid MG ; operational strategies; frequency control; PowerFactory;

    Abstract : The purpose of this study is to analyse how a battery energy storage system (BESS) can support the frequency and voltage stability for an islanded microgrid containing a hydropower plant. Two different microgrids, both situated in Sweden, are evaluated. Modelling and dynamic simulations are conducted in the PowerFactory tool. READ MORE

  4. 3. LCA of Microgrid System: a Case Study at ‘North-five Islands’ of Changshan Archipelago, China

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

    Author : Jiang Yuning; [2019]
    Keywords : Microgrid system; Life cycle Assessment LCA ; Climate change impact; Greenhouse gas emissions GHG ; China;

    Abstract : Microgrid can provide stable, clean, and sustainable electricity supply for remote places since it can operate on renewable energy sources and work isolated from the utility grid. This thesis evaluates the life cycle greenhouse gas (GHG) emissions of the microgrid system which is located at the ‘North-five Islands’ of Changshan archipelago in China. READ MORE

  5. 4. Analysis of Simris Hybrid Energy System Design and Working and Checking the Effects of Using High Capacity Factor Wind Turbine

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

    Author : Naeem Akhtar; [2019]
    Keywords : Renewable energy; Microgrids; Wind turbines; Solar PV; Storage betteries;

    Abstract : The world is entering the future where integration of renewable energy sources within the power grid will play an important role when facing the challenge of reducing global warming. The intermittent generation characteristics associate with renewable energy sources can be handled by the implementation of microgrids. READ MORE

  6. 5. Microgrid Safety and Protection Strategies

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Aryudha Hartono; [2018]
    Keywords : IB-RES; grid-connected mode; islanded mode; short circuit; IED; directional zero and negative sequence current protection; unbalanced load flow; protection coordination; fault ride-through;

    Abstract : One of the challenging issues with the Microgrid is that the bidirectional power flow providedby the distributed generator (DG) which modify the fault current level. Furthermore, theinverter based-renewable energy source (IB-RES) limits the total fault current contributionto the grid due to its thermal capability. READ MORE
