Abstract

This paper performs optimization-based controller design to avoid control interaction among multiple converter-interfaced generators (CIGs). To assess the control interaction between CIGs, an impedance-based stability analysis. Unexpected instability resulting from the CIG disconnection is investigated in a test case where three CIGs are connected to a microgrid. Parameter sensitivity is performed to determine which control parameter has more influence on the stability, and particle swarm optimization is utilized to adjust the control parameters to enhance the stability with computational efficiency. Simulation results demonstrated that the proposed tuning procedure helps ensure the stability of the test case even if a CIG is disconnected from the grid.
