Multilevel MATE for Efficient Simultaneous Solution of Control Systems and Nonlinearities in the OVNI Simulator

Summary form only given: This paper presents the solution approach for simulation of control systems and nonlinearities used in UBC\´s OVNI ("object virtual network integrator") power system simulator. OVNI is aimed at simulation of full size power system networks in real time using integrated software/hardware solutions. The software solution is based on the MATE ("multi-area thevenin equivalent") network partitioning framework. "Multilevel MATE" expands the concept of MATE to a subsystem level, allowing for the efficient inclusion of controllers\´ equations and nonlinearities.
