Hybrid operational approach for PV/DG microgrid without storage device

A hybrid approach is proposed in this research work as a grid connected PV/DG power generation systems without a battery bank. The aim of the proposed approach is to maintain power quality during operations and regulate the PV and DG output as per the load variations. Further the suggested approach will also restrict the PV system inverters to feed the excess energy into grid. A controller is also designed with the proposed hybrid approach to check the solution accuracy at real outdoor systems. Two different case study sites are selected to check the effectiveness of the controller based on proposed hybrid approach. The results at both the sites for different scenario are found to be very effective under all the load conditions. The suggested model will not only aid in the smooth operation of grid-connected PV/DG systems, but will also conserve fuel in DG, lowering fuel costs and reducing GHG emissions.
