Abstract: |
In this study, controller parameters of static var
compensators (SVCs) at planned locations are optimized to
mitigate fault-induced delayed voltage recovery issues and
improve angular stability of a multi-machine power system.
The problem is formulated as a nonlinear optimization
problem involving constraints on post-fault trajectories of
voltages and frequencies. This paper proposes a mesh
adaptive direct search based algorithm interfaced with a
power system simulator for optimization of SVC controller
parameters. The proposed method is tested on the NPCC
140-bus system to optimize controller parameters for three
SVCs. Simulations on critical contingencies verify that
post-fault transient voltages and generator speeds can both
quickly recover and transient stability of the system is
improved. |
