This paper presents model predictive control method for load shedding based on trajectory sensitivities. According to the basic principle of model predictive control, aiming at minimizing the quadric performance index which comprehensively considers both the control cost and the deviation between bus voltage predictive trajectories and their reference values, the receding optimization model is described...
Voltage instability and voltage collapse are complicated phenomenon which can be influenced by the interactions of all power system components. This paper presents an approach for optimal coordination of static Var compensators (SVCs), transformer under load tap changers (ULTCs) and load shedding to improve voltage performance following disturbances and also to ensure a desired amount of post-transient...
The paper proposes a two-stage model predictive control (MPC) strategy for alleviating voltage collapse. The first stage uses a static load shedding algorithm to obtain stable MPC prediction simulations. The second stage uses the MPC simulations, and associated trajectory sensitivities, to establish a linear program (LP) that optimizes the control action. This LP builds on trajectory approximations...
