MPC Energy Management System For A Grid-Connected Renewable Energy/Battery Hybrid Power Plant

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 composed by a wind energy conversion system (WECS) and a LiION 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 efficiently the battery’s charge/discharge cycles and state-of-charge (SoC) to meet the generation commitments while considering the BESS lifespan. The energy management system is tested via Matlab/Simulink software by using real wind data.
