| Sumario: | In this Master’s Thesis, a control architecture for a microgrid containing a Fuel Cell, Superca- pacitor and lithium-ion Battery (BT) has been developed, with the goal to be implementable in the microgrid located in the FC Lab of IRI. The mentioned microgrid has been modified with the addition of the BT, for which hardware and software had to be developed. As the topology of the microgrid is full-active, which means that every element is connected to a DC bus through a power converter, the control of this converters has been also designed, simulated and implemented. In order of effectively integrating the BT into the microgrid, a battery voltage model has been developed and fitted, and then used in the BT SoC estimation using EKF. Then, a strategy based in Filter-Based Control (FBC) has been developed and simulated, taking as case of application the behaviour of a van in the WLTP cycle. It has been found that the control could successfully manage the power distribution under this case, maintaining the bus voltage at the desired reference and the BT and SC SoCs within the desired ranges |
