Electrical Distribution Modeling:An Integration of Engineering Analysis and Geographic Information Systems
This thesis demonstrates the value of integrating electrical distribution engineering analysis with Geographic Information Systems (GIS). The 37-Node IEEE Feeder model was used as the base distribution system in this study. It was modeled separately, both in software capable of unbalanced load-flow …

Optimizing automotive electrical distribution systems design and development by reducing design iterations
The design and development (D&D) of electrical distribution systems (EDS) is a practice that has been performed in the automotive industry for more than 100 years. The amount of technology infusion in vehicles within this history impacts the design and development of electrical distribution systems …
