A Review of Matrix Algebra for Power and Energy Applications

Abstract

This report presents a brief review of matrix algebra and its implementation in Julia for power and energy applications. First, we present basic examples of data visualization, followed by conventional operations with matrices and vectors. Then, we study quadratic forms and norms, two main concepts required in the convergence study of the power flow in power and energy applications. After that, we give good practices to create a neat code in Julia. There is an extensive set of examples available on the Internet related to these basic aspects, so we avoid repeating what is well documented. Hence, we show only basic examples to create our first scripts.
