Abstract :
Electrolytic hydrogen offers a promising alternative for long-term energy storage of renewable energy
(RE). A stand-alone RE system based on energy storage in the form of hydrogen has been developed at the
Hydrogen Research Institute and successfully tested for automatic operation with an in-house designed
control system and power conditioning devices. In this system the excess energy with respect to load demand
is sent to the electrolyzer to produce hydrogen which, when properly stored, is available to the fuel cell to
produce electricity when there is insufficient wind and solar energy with respect to load requirement. The RE
system components have substantially different voltage-current characteristics, and they are integrated
through the designed and developed power conditioning devices on a DC bus, which allows power to be
managed between input power, energy storage and load. The DC-DC buck and boost converters are
connected for power conditioning between the DC bus and the electrolyzer, and between the fuel cell and the
DC bus, respectively. With respect to the energy level at the DC bus and the control strategy, the controller
sends the conditioned signal (duty ratio) to the digitally controlled DC-DC converters for on/off operation,
thus controlling the power flow to the electrolyzer and from the fuel cell. The converters' control is based on
a chopper multiphase switching technique, which reduces the harmonics levels and ripples with a simple
additional filter. The simulated and experimental results of the boost and buck converter operations are
compared. Also the effect of duty ratio with respect to the number of cells in the converters has been studied
for harmonic reduction. It has been found that the designed and developed DC-DC converters and the control
system give effective power flow control with automatic operation of the system under different load
conditions and with intermittent inputs from wind turbine generator and photovoltaic array.
