Abstract
This paper presents the preliminary study of the modeling of a small standalone AC system with the fuel cells and solar panels as energy resources. The solar energy will be the main energy source for electricity generation during the day and will be complemented with the fuel cell when needed. The fuel cell and the battery will be responsible to meet the electricity demand during the night. The dynamic Simulink models of the fuel cell and the photovoltaic cell are implemented and the load characteristics were obtained for both. The system also includes two DC/DC converters to boost the output voltage from both the fuel cell and PV cell to 80V DC. The DC/AC PWM inverter is involved to converter DC to the standard AC voltage suitable for general household appliances. The power management strategy and the load sharing controller are the two main research jobs currently undergoing.
