A Viable Residential Dc Microgrid For Low Income Communities – Architecture, Protection And Education, Karthik Palaniappan
A Viable Residential Dc Microgrid For Low Income Communities – Architecture, Protection And Education, Karthik Palaniappan
Theses and Dissertations
The availability of fossil fuels in the future and the environmental effects such as the carbon footprint of the existing methodologies to produce electricity is an increasing area of concern. In rural areas of under-developed parts of the world, the problem is lack of access to electrification. DC microgrids have become a proven solution to electrification in these areas with demonstrated exceptional quality of power, high reliability, efficiency, and simplified integration between renewable energy sources (principally solar PV) and energy storage. In the United States, a different problem occurs that can be addressed with the same DC microgrid approach that …

Solid State Protective Device Topological Trade-Offs For Mvdc Systems, Vikas Singh
Solid State Protective Device Topological Trade-Offs For Mvdc Systems, Vikas Singh
Theses and Dissertations
Presently accepted approaches to protection are “Unit-Based” which means the power converter(s) feeding the bus coordinate with no-load electromechanical switches to isolate faulted portions of the bus. However, “Breaker-Based” approaches, which rely upon solid state circuit breakers for fault mitigation can result in higher reliability of power and potentially higher survivability. The inherent speed of operation of solid state protective devices will also play a role in fault isolation, hence reducing stress level on all system components. A comparison study is performed of protective device topologies that are suitable for shipboard distribution systems rated between 4kVdc and 20kVdc from the …
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 …
