A parking lot for fuel cell cars is considered inside a microgrid where the fuel cell cars are exploited to generate power inside the microgrid. A central control unit is considered in the microgrid in order to guarantee the power balance of the microgrid by means of scheduling the power generation of fuel cell cars. To compensate the uncertainty in the prediction of the load, three robust model predictive control methods are designed. Simulation of a case study compares the developed control methods and the performance of each method is evaluated.
