Abstract

This paper proposes a multi-agent technique that is divided into two parts. The first part is a tracking agent that will track generators rotor angle to determine power system instability. According to the tracking agent's output, control agent is initiated. The tracking agent uses off-line time domain analysis to build look-up tables of required fast valving. The tracking agent employs two sub-agents. The first sub-agent determines if fast valving is required to attain transient stability for each credible system disturbance and operating condition. The second sub-agent compares the electric power for each generator before and after the disturbance to determine the appropriate reduction of mechanical power to stabilize the system. The control agent is turbine fast valving. The resulting multi-agent technique can determine system instability and establish system stability. Decoded MATLAB programs of both agents are linked to ETMSP program, power system simulation program, used in verifying the results.
