Bus inertia for enhancing dynamic flexibility of hybrid power systems

A computer system comprising:

• one or more data processors;
• and
• one or more memory devices storing computer-readable instructions that, upon execution by the one or more data processors, configure the computer system to:
• receive data from a plurality of synchronous machines and phasor measurement units (PMUs) located in different geographic regions of a power grid,
• the data including an augmented admittance matrix;
• input the data into a real-time power grid model comprising non-linear algorithms;
• determine an output of the real-time power grid model, the output comprising bus inertia indicating a distribution of total inertia across a plurality of buses located in the different geographic regions of the power grid, wherein inertia for a bus indicating a capability of the bus to resist changes when a disturbance occurs, and wherein the bus inertia is determined based on a bus weightage matrix that indicates measurements of electrical distances between buses and physical generator inertia;
• and
• cause at least one action to be implemented based on the bus inertia.
