Modeling And Protection Scheme For Ieee 34 Radial Distribution Feeder With And Without Distributed Generation, Sidharth Parmar Ashok
Modeling And Protection Scheme For Ieee 34 Radial Distribution Feeder With And Without Distributed Generation, Sidharth Parmar Ashok
Theses and Dissertations
The existing power system was not designed with distribution generation (DG) in mind. As DG penetration is being considered by many distribution utilities, there is a rising need to address many incompatibility issues which puts a big emphasis on the need to review and implement suitable protection scheme. The usual practice for existing distribution feeders is the Overcurrent scheme which includes coordination between fuses and reclosers. But when DG is added to the distribution feeder, the configuration is no more radial as there is contribution of fault currents from the DG's and if the existing protection scheme is applied then …

Modeling, Analyses And Assessment Of Microgrids Considering High Renewable Energy Penetration, Qiang Fu
Theses and Dissertations
Microgrids are receiving attention due to the increasing need to integrate distributed generations and to ensure power quality and provide energy surety to the customers. Since renewables need to be in the mix for energy surety, a high renewable-energy penetrated microgrid is analyzed in this paper. The standard IEEE 34 bus distribution feeder is adapted and managed as a microgrid by adding distributed generation and load profiles. The 25kV system parameters are scaled down to 12kV and renewable sources including solar PV and wind turbines, an energy storage system, and a natural gas generator have been added to the 34-bus …
Dc Microgrid Modeling And Energy Storage Placement To Enhance System Stability, Carl Westerby
Dc Microgrid Modeling And Energy Storage Placement To Enhance System Stability, Carl Westerby
Theses and Dissertations
The work of this thesis represents a joint venture between the University of Wisconsin-Milwaukee and the University of Wisconsin-Madison. A DC microgrid is selected for the efficiency benefits, lack of reactive power in the system, and ease of connecting to an AC grid. The system modeling relies on physical parameters and industry standard methods for the estimation of loads and lines. An example model is created for the University of Wisconsin - Milwaukee's Campus. Due to the high penetration of renewable energy sources in the example model, system stability is a concern. To help mitigate stability issues, analysis is performed …
