The paper presents experimental results from the operation of a test bench constituted of a Grid-connected Hybrid system. This device includes wind and photovoltaic (PV) physical emulators, battery energy storage, load and a controlled interconnection to the Low Voltage (LV) grid. Both the Wind generation unit and the PV generation unit are connected to the weak AC grid via a single phase inverter with a lead acid accumulator. The grid power inverter is suitably controlled to permit the operation of the system either interconnected to the LV grid, or in standalone mode, with a seamless transfer from the one mode to the other. The paper provides a technical description of the Hybrid system devices and of the inverter energy management, along with extensive measurement results which demonstrate the system capability to operate in the aforementioned mode.
