Power Distribution System Analysis (ECE 5984)
Course Overview
This course covers the fundamentals of electric power distribution systems. With increased deployment of distributed generation, controllable loads and metering devices, it has become more and more important for researchers and power industry professionals to better understand power distribution systems. This course commences with an overview of distribution networks, including their components, typical topologies, and operational strategies. It continues with the characteristics and representations of electric loads. Key components in distribution grids, including unbalanced line segments, voltage regulators, and three-phase transformers will be studied. These topics will be further integrated into the power flow analysis for unbalanced distribution networks. It also discusses recent advances on approximate grid models and convex relaxations for optimal power flow.
