Hierarchical Control Based on MPC for a Smart-Grid Including Power Distribution

The rapid growth of smart grids necessitates advanced control strategies to ensure efficient and reliable power distribution. This paper proposes a hierarchical control framework based on Model Predictive Control (MPC) for managing power distribution in a smart grid. The hierarchical structure comprises three control levels: the first hierarchy is to control the inverter variables and the LC filter voltage, the second hierarchy supervises the power control restriction for every inverter, and the hierarchy is for power coordination, which utilizes long-term condition and prediction and power supply restriction (solar or wind capability, among other conditions or restrictions). The simulation results presented in this paper validate the fast control response and the capability of coordination between the different hierarchies of the proposed strategy.
