This paper describes a methodology for implementing in FPGA models of photovoltaic panels for Hardware-in-the-Loop (HIL) and real-time simulations. The proposed methodology integrates numerical solutions, SysML diagrams and Petri nets for structural design and formal validation. In this study, photovoltaic cells have been modeled using the single diode circuit. The photovoltaic panel model is solved...
This paper outlines a methodology for modeling photovoltaic systems in embedded hardware. This methodology uses the HiLeS platform to transform SysML models in Petri nets and generate VHDL code. The proposed methodology is intended for Hardware-in-the-Loop simulations of power converters and PV panels in microgrids. In addition, this methodology allows the design of MPPT controllers for their direct...
The rapid increase in the integration of distributed resources such as distributed generation (DG), demand response (DR) and electricity storage (ES) requires management schemes to integrate distributed resources into low and medium electricity networks. Energy management represents a challenge for operation of electric grids when distributed resources are merged into the network. This paper address...
Swarm robotics requires the development of new strategies and algorithm integration, which allow for the improvement of the design and the applications for harvesting or collecting resources.
