Agent based coordinated control of protection devices for transient stability enhancement
conference contribution
posted on 2013-01-01, 00:00 authored by Md Shihanur Rahman, H R Pota, T F OrchiThis paper presents the use of the multi-agent
technology in order to enhance the transient stability of power
systems by the dynamic evaluation of the critical clearing time
(CCT) including the effect of the distance of fault locations and
the impact of the renewable energy source (RES) integration. A
multi-agent framework is developed in this research, where the
intelligent agents use an algorithm for coordinating the protection
devices to isolate the faulted part from the rest of the system
before the corresponding CCT, so as to increase the stability
margin of the system for the transient stability assessment.
Simulations are carried out on a multimachine test system for
different fault locations and the stability of the system is observed
from the simulation of the machine’s relative rotor angles.
