Multilevel MATE for efficient simultaneous solution of control systems and nonlinearities in the OVNI simulator

This paper presents the solution approach for simulation of control systems and nonlinearities used in UBC's Object Virtual Network Integrator (OVNI) 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 Multiarea Thevenin Equivalent (MATE) network partitioning framework. Multilevel MATE expands the concept of MATE to a subsystem level, allowing for the efficient inclusion of controllers' equations and nonlinearities
