Critical transmission outages often cause line overloading and voltage degradation. Without corrective action, eventually overloaded lines may trip and/or voltage collapse may ensue. Importantly, these secondary effects evolve relatively slowly, allowing sufficient time for corrective controls to be enacted. This talk will present receding horizon model predictive control (MPC) strategies that capture the relevant dynamics governing the thermal behaviour of overloaded transmission lines. The controls available to MPC include generation set-points, energy storage and load regulation. MPC determines the optimal use of those resources, subject to a variety of constraints that include rate limits and resource availability. The proposed corrective control strategies will be illustrated using a system of around 100 nodes.
