| Research Abstract |
A topology of the interconnected hybrid generating system with photovoltaic cells and a wind turbine to the AC power grid has been investigated in this research. We have first discussed the interconnected wind generating system. DC Motor simulating the wind turbine drives the Permanent Magnet Synchronous Generator. The generating AC power should be converted to the DC by diode rectifier, and then be interconnected to the AC power grid through the three-phase current source inverter. By adjusting only the modulation factor in the inverter appropriately, the maximum power in each wind velocity can output to the grid regardless of the wind fluctuation.
Next, the solar generating system has been discussed so that plural PV panels under the different solar irradiances can output the respective maximum powers. The cascaded boost choppers are connected to such two PV panels. It has been made clear by several experiments that the proposed system can carry out the above purpose.
Finally, in order to combine properly the both PV and wind generating voltages, the DC-DC converter applied with the series-parallel chopper is employed. Even if the solar irradiance and the wind velocity are fluctuated violently, the inverter circuit can be operated stably, and the respective maximum output powers can be supplied to the grid by controlling the duty factor in the converter and the modulation factor in the inverter.
