Inertial, Governor, And Agc/Economic Dispatch Load Flow Simulations Of Loss Of Generation Contingencies

Abstract

The transient phenomena associated with the loss of generation contingency is described in this paper. The propagation of the disturbance, the time instant at which the inertial load flow captures a snapshot of the transient, and the time instant at which the governor load flow captures a snapshot of the transient is described. A method of determining the subset of generators that participate in governor load flow is described based on this discussion of the propagation and evolution of the transient phenomena associated with loss of generation contingencies. Finally, the application of inertial and governor load flow in planning is discussed. A description of the inertial and governor load flow program, developed for EPRI and residing in the EPRI Software Center, is described.
