MPC Energy Management System For A Grid-Connected Renewable Energy/Battery Hybrid Power Plant
Résumé
In this paper, an energy management system (EMS) based on model predictive control (MPC) and quadratic programming (QP) is presented. The control strategy manages the power performance of an island grid-connected hybrid plant combining a wind energy conversion system (WECS) and a Li-ION battery energy storage system (BESS). The hybrid plant should inject power into the grid continuously, subject to a commitment band previously fixed. For this, the proposed EMS handles the battery's charge/discharge cycles and state-of-charge (SoC) efficiently, to maintain the generation engagements while considering the BESS lifespan. The energy management system is tested via Matlab/Simulink software by using real wind data.
