Control strategy for utility interactive hybrid PV Hydrogen System

摘要

The combination of Photovoltaic (PV) with a hydrogen storage system as backup (HPVHS - Hybrid PV Hydrogen System) has been proposed in this paper. The Proposed system will cope up with the problems of grid connected PV System (GPVS) which is being stochastic in nature. The control strategy has been proposed for direct and indirect grid voltage regulation utilizing proposed HPVHS as static synchronous compensator (STATCOM). It has been shown that the HPVHS based on this control strategy would improve the dynamic behavior of the GPVS response to disturbance, voltage dips and in a day ahead market where decisions on the power supply should be taken at least 24 hours in advance. MATLAB/SIMULINK based simulation is done and results are provided to show the effectiveness of the proposed control strategy.
