EE 5240 provides practical insights and experience with mathematical formulations and programming/implementation of algorithms related to eletrical networks, both  large and small.  Many of the methods are also applicable to other areas of Electrical Engineering, and so this may also be an attractive elective for graduate students in specialties other than EE Power Systems.  The main goal of the course is to learn key computer algorithms and programing approaches and to provide programming experience.  A very valuable benefit of the course is also  to enhance understanding of the "number crunching" going on behind the scenes when you use commercial software simulation and analysis packages, so as to avoid  the age-old "Garbage-In / Garbage-Out" scenario. 

Computer analysis and simulation of power systems can be categorized as steady state, dynamic (eg. stability), and transient.  In recent years we have primarily been using Matlab for programing.  Topics typically covered in this 15-week course are as follows (textbook, instructor, and priorities may alter coverage):

• Network topology, [Zbus], [Ybus], incidence matrices. 
• Solution of Linear systems of Equations - Gaussian Elimination, Gauss-Jordan, LU factorization, other triangularization methods. Kron Reduction.
• Augmentation methods for ideal components - shorts, independent and dependent sources, ideal transformers.
  
• Sparsity Methods, Linked List Data Structures, Fills and Zeros, Reordering, Dynamic Data Structures.
  
• Opening data files, direct vs. sequential access, file formats, data types, pointers vs. offsets, practical I/O methods.  IEEE CDF (common data format). 
• Building [Ybus] one element at a time, transformers with off-nominal turns ratios, "switching" lines and transformes in and out of the network.
  
• Newton iteration, convergence, programing loadflow, voltage-controlled buses, transformer tap ratios, constained/optimal loadflow. 
• Symmetrical Components and Short-Circuit Analysis, [Ybus] for sequence networks, obtaining a row or column of [Zbus] from [Ybus] w/o inverting. 
• Numerical Integration methods
• The swing equation, System-Level Stability Analysis
• Introduction to Transient Analysis, time-domain methods based on [G], inductance and capacitance representation using injected "history" current.

Prerequisite Material

• Euler's Identity - The foundation of phasor analysis, hyperbolic functions (used for long transmission lines) 
• Matlab Programming (fundamentals).  Tutorials:  [ Part 1 Notes | Part 1 Video ]; [ Part 2 Notes | Part 2 Video ]
