Model Predictive Control

Definition

Model Predictive Control (MPC) is an advanced control strategy that uses a mathematical model to predict the future behavior of a system over a specified time horizon. By optimizing the control inputs based on these predictions, MPC effectively manages system performance while adhering to constraints. This approach is particularly valuable in power systems for enhancing stability and responsiveness, especially in dynamic environments like microgrids and wide-area networks.
