Power flow router sensititvities for post-contingency corrective control

Abstract

Power electronics based power flow routers are powerful tools that provide easy and cost-effective control of power flows in large-scale electricity networks. By adding additional controls, fast power flow routing can increase the secure operational range of bulk power systems both during normal operations and contingencies. Increased integration of power flow routers could allow the bulk power system to operate at a lower cost while maintaining, and possibly increasing, the level of security. In this paper, we develop power flow router sensitivities that enable corrective flow routing capabilities during post-contingency conditions.

“…A sensitivity method is employed in [11] to analyse the impact of PFCs on corrective power flow control. However, due to the inherent complexity of the method, power losses and the reactive power are not considered in [11]. In this paper, we develop a rigorous PFR load flow model characterized by "branch terminal voltages."…”
