2. 1. System-Wide Impacts of Distributed Generation on Power System Operation : Data-Driven Approaches to Addressing the Challenges of Integrating Distributed Generation

   Author : Tin Rabuzin; Lars Nordström; Marjan Popov; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; data-driven modelling; distributed generation; dynamic equivalencing; islanding detection; reduced order modelling; datadriven modellering; detektion av ödrift; distribuerad generation; dynamisk modellering; reducerad ordningsmodellering; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Deployment of distributed generation (DG) is happening at an increasing rate driven by both the need for the reduction of humanity's carbon footprint and economic opportunities. The trend of increasing penetration levels of DG has also introduced interdependence between the responsibilities of system operators and the owners of the generating units. READ MORE

4. 2. Electricity Distribution Network Planning Considering Distributed Generation

   Author : Yalin Huang; Lennart Söder; Karin Alvehag; Peiyuan Chen; KTH; []
   Keywords : Electricity distribution network; network planning; distributed generation; Electrical Engineering; Elektro- och systemteknik;

   Abstract : One of EU’s actions against climate change is to meet 20% of our energy needs from renewable resources. Given that the renewable resources are becoming more economical to extract electricity from, this will result in that more and more distributed generation (DG) will be connected to power distribution.

5. 3. Converter Interfaced Distributed Generation - Grid Interconnection Issues

   Author : Fainan Magueed; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VSC; harmonics; LCL-filter; power quality; weak grid; voltage regulation; vector control; strong grid; distributed generation; intentional islanding; L-filter; voltage dips;

   Abstract : Distributed generation (DG) with a converter interface to the grid is found in many of the green power resources applications. In this thesis, the control of a voltage source converter (VSC), as the DG front end, is in focus regarding the power quality problems that could appear at the connection point. READ MORE

6. 4. Impact of Economic Regulation on Distributed Generation Integration in Electricity Distribution Grids

   Author : Angela Picciariello; Lennart Söder; Karin Alvehag; Gert Brunekreeft; KTH; []
   Keywords : Distributed generation; distribution economic regulation; regulatory impact; distribution tariff design; cost allocation methodologies; cross subsidies; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Energy policies in favor of a larger adoption of renewable energy sources for electricity production purposes and the significant progress of several renewable technologies are among the main drivers behind an increasing integration of distributed generation (DG) in distribution networks.DG affects distribution network planning and operation and, consequently, higher or lower network costs than in a traditional passive network scenario arise.

7. 5. Efficient Integration of Distributed Generation in Electricity Distribution Networks - Voltage Control and Network Design

   Author : Ingmar Leisse; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coordinated Voltage Control; Distributed Generation; Electricity meter; PV; Wind Power; Distribution Network;

   Abstract : Distributed generation (DG), i.e. generation connected to the low and medium voltage distribution network (DN), has been increasing a lot during recent years. Thus the traditional assumption of a unidirectional power flow and a voltage decrease along the distribution feeders is no longer valid in all operation conditions. READ MORE
