This work is based on the master thesis proposal entitled “Autonomous operation of a hybrid microgrid using centralized and distributed control”. The selected microgrid architecture is composed of two Direct Current distribution buses and allows both grids connected and islanded operation. In Fig. 1, from left to right, the first bus is an Extra Low Voltage Direct Current (ELVDC) that operates to 48VDC, the second bus is Low Voltage Direct Current (LVDC) that operates to 240 VDC. Each bus interconnects several units that instantaneously supply, store or consume energy. In fact, each connected unit has a first level controller, which provides regulation of inner variables such as current and power. Besides, the development of any hybrid microgrid should guarantee the energy balance and regulation of the constant voltage in the buses, with the purpose of synchronizing each of the interconnected units. The propose includes a cooperative master-slave control where the control action changes between Pv, Pbatt, and Pilc. Each unit has different types of operation modes. And, the cooperative control will choose which unit is the master control. For the transition between the two units, cooperative control will be regulated with them at the same time using the logistic function as a transition reference.

SIRUI is research hotbed from the Engineering Research Group D+TEC. This initiative consists in an extra-class space where the engineering students create their own robotic platforms (Hardware and Software) according to their interests.

These low-cost developments involve prototyping tasks, handling of tools and equipment (3D print, laser cutter, PCB plotter, soldering), design and electronic implementation (Electronic simulation [Proteus], manufacture of PCBs), modeling and control (Dynamic simulation [MATLAB], Perception adaptations) and digital programing (Assembly, C, C++, Python, ROS, OpenCV).
