POWER MANAGEMENT STRATEGIES FOR GRID CONNECTED PV-FC HYBRID SYSTEM

The objective of this paper is to maintain the reference value of the Hybrid system by changing the output values of the Photovoltaic array and Fuel cell with corresponds to each other. And the logic implemented in this work is, at a given load the total load is driven by the Grid, Photovoltaic and Fuel cell. Here the total load should be supplied by the PV array; if the load demand is not reached by the PV array then the Fuel cell is added to the PV array. Even though, if the load demand is not reached, the Grid will be connected to it to meet the load demand. In all these cases simulated system will maintain voltage and frequency at specified Value.
