The Hybrid system refers to those applications in which multiple energy conversion devices are used together to supply an energy requirements. The hybrid system can either be connected to the main grid or work autonomously with respect to the grid-connected mode. In the grid-connected mode, the hybrid source is connected to the main grid at the point of common coupling (PCC) to deliver power to the load. When load demand changes, the power supplied by the main grid and hybrid system must be properly changed. The power delivered from the main grid and PV (Photo Voltaic) array as well as FC (Fuel Cell) must be coordinated to meet load demand. The hybrid source has two control modes: 1) unit-power control (UPC) mode and feeder-flow control (FFC) mode. In the UPC mode, variations of load demand are compensated by the main grid because the hybrid source output is regulated to reference power. Therefore, the reference value of the hybrid source output must be determined. In the FFC mode, the feeder flow is regulated to a constant, the extra load demand is picked up by the hybrid source, and, hence, the feeder reference power must be known. This paper presents a method to operate a grid connected hybrid system. The hybrid system composed of a Photovoltaic (PV) array and a Fuel cell (FC) is considered. This output can be obtained for two modes of operation using perturbation and observation algorithm. The effectiveness of the proposed method was tested on grid connected PV-FC system using Simulink in MATLAB.
