Power flow control in electric power systems by use of controllable series power capacitors and phase shifters is discussed. Models suitable for incorporation in power flow programs are developed and analyzed. The power flow control problem is defined in a stringent way, and a method for solving the power flow control problem is proposed based on decomposition. This method is applied on test systems and the convergence rate of the algorithm is discussed. Simplified models of the components are also derived. These simplified models are shown to be quite accurate in most situations, and are used to construct regions of feasible power flows of the controlled lines. >read more

Sensitivity in Power Systems
TL;DR: In this article, two dominant types of sensitivity relations are defined, namely sensitivity of one electrical variable such as the voltage Vi at node i, with respect to another electrical variable, such as reactive production Qj at node j, and sensitivity of the operating cost F with respect with such electrical variables as the consumption Ci at vertex i and the production Pj at vertex j.
