  This paper proposes a robust transient stability constrained optimal power
flow problem that addresses renewable uncertainties by the coordination of
generation re-dispatch and power flow router (PFR) tuning.PFR refers to a
general type of network-side controller that enlarges the feasible region of
the OPF problem. The coordination between network-side and generator-side
control in the proposed model is more general than the traditional methods
which focus on generation dispatch only. An offline-online solution framework
is developed to solve the problem efficiently. Under this framework the
original problem is significantly simplified, so that we only need to solve a
low-dimensional deterministic problem at the online stage to achieve real-time
implementation with a high robustness level. The proposed method is verified on
the modified New England 39-bus system. Numerical results demonstrate that the
proposed method is efficient and shows good performance on economy and
robustness.
