Electric grids are interconnected complex systems consisting of generation, transmission, distribution, and active\nloads, recently called prosumers as they produce and consume electric energy. Additionally, these encompass a\nvast array of equipment such as machines, power transformers, capacitor banks, power electronic devices, motors,\netc. that are continuously evolving in their demand characteristics. Given these conditions, signal processing is\nbecoming an essential assessment tool to enable the engineer and researcher to understand, plan, design, and\noperate the complex and smart electronic grid of the future. This paper focuses on recent developments associated\nwith signal processing applied to power system analysis in terms of characterization and diagnostics. The following\ntechniques are reviewed and their characteristics and applications discussed: active power system monitoring,\nsparse representation of power system signal, real-time resampling, and time-frequency (i.e., wavelets) applied to\npower fluctuations.
