“…Then the constraint can be determined by restricting the critical OMIB trajectory corresponding to the unstable condition [14]. Furthermore, the OMIB's stability margin can be defined as a multi-variable linear function of the mechanical power exchange between generators [28]. Thus, SIME-based transient stability analysis provides information of OMIB stability margin with defined fault clearing time and mechanical power of the OMIB equivalent.…”

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.Index Terms-Transient stability, optimal power flow, robust optimization, power flow router, renewable energy.
