ANDES: A Python-Based Cyber-Physical Power System Simulation Tool

This paper introduces the design and implementation of a Python-based software package for cyber-physical power system research called Andes. Andes is developed in an attempt to bridge the gap between the traditional power system analysis and the fast-growing needs for cybersecurity studies. First, the architecture design is proposed to accommodate for power grid prototyping, communication network set up, and the interactions between the two. Design considerations are discussed from the research and development perspective. Examples are shown using Andes for modeling, monitoring, and visualization of cyber-physical power system studies.
