Modeling power system buses using performance based earthquake engineering methods

摘要

The Pacific Northwest region is in a constant threat of an imminent earthquake event. Numerous efforts are being made to make the electrical grid in the region more resilient to seismic activities. Performance-Based Earthquake Engineering (PBEE) is one of the approaches being used by researchers to analyze the risk associated with structures such as buildings and bridges. This research intends to introduce modeling of power systems using the PBEE method. Each bus in a one-line representation of a power system is a mini-substation with a different configuration and should be modeled as such. This paper also proposes guidelines for modeling every bus of a power system. Application of these guidelines on a 3-bus system is illustrated. An augmented model for a general power system with arbitrary number of buses is also described for adding system resiliency considerations.
