An adaptive optimal protection of a distribution system using a multi-agent system

Abstract

This paper suggests an adaptive optimal protection scheme using multi-agent concept. An OCR agent, a software system to protect power devices from over current, is installed in every protective device and renews its parameters whenever a change in the operation condition occurs, in the manner that a performance measure is maximized. Protective effectiveness measure is adopted as the performance measure, in this paper. Simulations in a variety of cases show the possibility of application of the proposed scheme in power system protection.
