Critical clearing time sensitivity for inequality constrained systems. Mishra, C., Pal, A., & Centeno, V. A. In IEEE Power Energy Society General Meeting (PESGM), pages 1–5, Atlanta, GA., August, 2019. ISSN: 1944-9933

From a stability perspective, a renewable generation (RG)-rich power system is a constrained system. As the quasi-stability boundary of a constrained system is structurally very different from that of an unconstrained system, finding the sensitivity of critical clearing time (CCT) to change in system parameters is very beneficial for a constrained power system, especially for planning/revising constraints arising from system protection settings. In this paper, we derive the first order sensitivity of a constrained power system using trajectory sensitivities of fault-on and post-fault trajectories. The results for the test system demonstrate the dependence between ability to meet angle and frequency constraints, and change in power system parameters such as operating conditions and inertia.
