Abstract: The integration of renewable energy resources and employment of multi-terminal dc links have dramatically transformed the structure of traditional power systems into hybrid networks with reduced inertia levels. A novel approach is proposed for determining bus inertia that captures power system dynamics and facilitates the real-time computation of grid flexibility. The bus inertia is defined as the distribution of the total inertia across all of the system buses, located in different geographical regions. The computation of bus inertia can use augmented admittance matrix, bus voltages, line parameters, inertia constants, and internal voltage setpoints of synchronous machines. The determination of bus inertia can be used during planning and operation phases that span long and short-time horizons to enhance system flexibility.
