1. 1. Power quality analysis and techno-economic modeling for microgrids

   Författare :Jakob Nömm; Sarah Rönnberg; Math Bollen; Josep Guerrero; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power Quality; Economy; Microgrids; Electric Power Engineering; Elkraftteknik;

   Sammanfattning : The work done in this thesis considers microgrids from two different aspects. Power quality and techno-economics of microgrids. Detailed power quality measurements have been made at a single house hydrogen-solar microgrid that consists of state-of-the-art energy efficiency technology, energy production and energy storage.

3. 2. Optimal Energy and Flexibility Dispatch of Grid-Connected Microgrids

   Författare :Kyriaki Antoniadou-Plytaria; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexibility; microgrids; Battery energy storage; optimization.; energy scheduling; energy management; distribution network;

   Sammanfattning : This thesis proposes an optimization model to efficiently schedule energy and flexibilities of a grid-connected microgrid (MG) with non-dispatchable renewable energy sources and battery energy storages (BESs). The model can also be used to coordinate the MG operation with the connected upstream distribution grid and to assess the MG flexibility considering economic viability, technical feasibility, and BES degradation.

4. 3. Optimal Energy Scheduling of Grid-connected Microgrids with Battery Energy Storage

   Författare :Kyriaki Antoniadou-Plytaria; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy management; Battery energy storage; distribution network; optimization; energy scheduling; microgrids;

   Sammanfattning : The coupling of small-scale renewable-based energy sources, such as photovoltaic systems, with residential battery energy storages forms clusters of local energy resources and customers, which can be represented as controllable entities to the main distribution grid. The operation of these clusters is similar to that of grid-connected microgrids. LÄS MER

5. 4. Risk-Averse Planning, Operation, and Coordination of Energy Systems Considering Uncertainty Modeling and Flexibility Services

   Författare :Hamed Bakhtiari; Jin Zhong; Manuel Alvarez; Jalal Kazempour; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system planning and operation; energy systems coordination; uncertainty modeling; microgrids; renewable energy; Electric Power Engineering; Elkraftteknik;

   Sammanfattning : Uncertainty sources affect the planning and operation of energy systems. Different system operators need proper alternatives to cope with these uncertainties and improve the operation of their systems from technical and economical viewpoints. LÄS MER

7. 5. Optimal and Resilient Control with Applications in Smart Distribution Grids

   Författare :Kaveh Paridari; Henrik Sandberg; De Persis Claudio; KTH; []
