An economic MPC approach for a microgrid energy management system

In this paper we address the problem of managing the energy production of a microgrid while satisfying a given demand. Emerging from the Smart Grid technologies, microgrids can be considered as subsections of the main grid with the capability to operate connected or isolated from the main network. An Economic Model Predictive Control (EMPC) scheme is proposed in order to achieve the optimal economic performance in the operational costs of the microgrid. The control scheme is tested in a simulated microgrid composed of a wind turbine, a set of PV panels, an energy storage device, and the connection to the main grid.
