Abstract

AbstractPower system inertia is receiving increasing attention because the inclusion of renewable energy generation equipment weakens the inertia of the regional equivalent system and affects the transient stability of the system. In this paper, the influence of variation of inertia constant on the transient stability of the system is studied analytically by adding short‐circuit faults, Equal Area Criterion, and derivation of equations. On the basis of theoretical analysis, multi‐machine system is established to simulate and verify the correctness of the analysis results.
