Small-scale test bench of a hybrid power system

The study of behaviour of the hybrid power systems (HPS) for remote areas is one of research axes of our laboratory. Simulink blocks with models corresponding to all the system parts have been developed. Control laws have been implemented to ensure the optimal power retrieval, the system stability and the output power quality. In order to make possible the models and the control laws validation, a small scale HPS (1:100 of power) is under construction. It is composed of renewable sources (a wind turbine generator and photovoltaic panels), buffer batteries, DC/DC and DC/AC converters, diesel generator and load/faults emulator. For the system development some stages is necessary. Beginning with a simple starting structure, in every step a part is added or changed and the system operation is verified
