Voltage Stability Margin Computation and Visualization for Tri-State South Colorado Area using EPRI Power System Voltage Stability Region (PSVSR) Program

摘要

A comprehensive study has been performed to compute the voltage stability margin for Tri-State South Colorado area using EPRI power system voltage stability region (PSVSR) program. We determined the critical cut-sets to separate the weak region from the rest of the transmission network, calculated the voltage stability boundaries in cut-set state space, and investigated remedial action schemes.
