Implementation of a dual input DC-DC boost converter for solar and fuel cell integration with a smart grid

This research involves the implementation of a dual-input DC-DC boost converter for integrating solar and fuel cell energy sources with a smart grid. The growing demand for renewable energy sources necessitates the efficient utilization and integration of multiple energy systems. The proposed dual-input converter enables simultaneous extraction and management of power from solar panels and fuel cells, resulting in improved energy generation and utilization. The converter incorporates a smart grid interface, allowing bidirectional power flow between the energy sources and the grid. The design and control strategy of the dual-input converter are discussed in detail, with a focus on achieving high conversion efficiency, maximum power point tracking, and optimal power sharing between the solar panels and fuel cells. The control algorithm utilizes a combination of Perturb and Observe (P&O) and Incremental Conductance (IncCond) methods for Maximum Power Point Tracking (MPPT), ensuring efficient power extraction from the solar panels. Additionally, a Proportional-Integral (PI) controller is implemented to regulate power flow between the energy sources and the grid. Simulation and experimental results are presented to validate the proposed converter's performance under various operating conditions.
