A Multi-Agent Approach to Electric Power Systems

Abstract

Electric power systems are rather complicated objects for modeling, investigation and control because of many elements and complex structure. Comprehensive multi-functional software is necessary to study multi-dimensional systems of the kind. The problems of current state estimation should be solved for monitoring of electric power system operation conditions. Emergency control actions are required to improve stability of electric power systems. A multi-agent approach can be used to solve such complex problems of electric power systems. The chapter deals with the following important areas of modeling, investigation and control of large electric power systems: • Effective construction of comprehensive software by using the multi-agent approach; • Decomposition of state estimation problem for large electric power system by using phasor measurement units and the multi-agent approach; • Multi-agent approach to coordination of emergency control devices against voltage collapse. The effectiveness of multi-agent approach for solving the above problems is illustrated by test examples.
