This paper proposes a multi-agent transient stability platform for the study of self-operation of multiple microgrids. This platform combines a MATLAB-based time domain simulation of the grid's transient stability with a JAVA-JADE (JAVA Agent DEvelopment Framework) which supports the development of multi-agent systems that utilize distributed artificial intelligence techniques that support simultaneous, geographically-distributed, and coordinated decision-making techniques. This hybrid platform leverages the numerical strengths of MATLAB with JAVA's multi-threaded decision-making capability. To that effect, the platform was tested on two complementary test cases: one to demonstrate a dynamic reconfiguration capability and another to demonstrate the decentralized dispatch of multiple microgrids. The work presents many opportunities for future developments in the domain of resilient self-healing operation of power grids.
