Advanced Reconfiguration and Protection of Distribution Systems: Four Areas of Supporting Research

Abstract

Historically, distribution systems have been very susceptible to transmission- and distribution-level events, such as line trips and faults within substations, because local sources of energy, if available at all, were only designed to operate in the context of a fully functional grid. However, the increasing deployment of advanced measuring devices, distributed energy resources (DERs), and energy storage provide the opportunity to improve reliability at the distribution level using advanced measurement-based reconfiguration and protection methods. This report discusses research regarding 1) a transmission equivalent model, 2) an algorithm for distinguishing between transmission- and distribution-level events, 3) a spreadsheet to help site new measurement devices, and 4) network theory to enable smart reconfiguration of distribution systems. Each of these areas of research support the development and study of advanced reconfiguration and protection methods.
