This course is an examination of the evolution of DER networks based on the IEEE 2030.5 standard, how this evolution introduces cybersecurity risks, and how these risks can be mitigated. While there are no pre-requisites for this course, students with prior knowledge of DER and/or data communication systems based on TCP/IP protocols will benefit most. It is intended for students who are interested in exploring technical (e.g. cybersecurity, engineering, software, systems management), professional (e.g. architecture, marketing, finance), and operational (e.g. operations & maintenance, sit monitoring) careers in the rapidly growing distributed energy industry. Students will acquire a foundation in the basic cybersecurity concepts that are needed to understand the more detailed considerations associated with securing DER in the grid.
