چکیده :

In this paper a control scheme based on hybrid model predictive control (HMPC) is peresented with two different cost functions for the energy management of a grid-connected microgrid (MG), including a battery storage devise, a diesel generator, a photovoltaic system and critical load. The real time controller relies on mixed-logical dynamical (MLD) model of the system, and is in charge of computing the operating conditions for each MG component over a 24-hour horizon, with sampling period of 60 min. An economic cost function proposed to minimize the operation cost. Furthermore, considering the terminal equality constraint an alternative cost function based on minimization of the battery tracking error is presented. The mentioned constraint is in charge of stability and recursive feasibility of operation. Moreover, simulation results are provided to show the advantages and disadvantages of both approaches
