rs action – Auto LTC – Load recover – Tie line flow by AGC ? After operator action – Manual LTC – Phase shifter – Manual HT bus voltage control with limit – Manual operation and adjustment to continuous rating Analysis of contingencies resulting in generationload mismatch ? Stage 1 During disturbance – Generator outputs according to electrical distance ? Stage 2 Following disturbance – Generator Accelerating and decelerating – Small system (inertia load flow) – Large system (by dynamic simulation) ? Stage 3 following the disturbance – Governor response load flow ? Stage 4 tens of seconds to several minutes – AGC response load flow
