In a large power system operating day-in-day-out owing to the variation of load, and under different contingencies in operation configuration of system in terms of generator and their connectivity to decentralized load may vary. After determining inertia at a particular bus through simulation or otherwise how can it be verified from online actual operation of power system?
For the disturbance at the bus the power swing with time could be monitored, putting the value of power with time in swing equation the inertia could be obtained for the bus….
Hello, for this aim I had proposed the vector parameter - "dynamic stiffness", as dS/dd, where dS - increment of full power, and dd - increment of load angles as vector values for some bus i of power system.
Dear Dr. Oleg, it appears to be interesting. Can a reference be given to understand in details and evaluate inertia from the rate of change of full power with respect to load angle?
