About Simulink Solar Energy Model

I have an assignment to do with Simulink, but I don't know how to do it. I want to use solar energy to produce energy, then use a DC-DC converter to electrolyze water and generate hydrogen, which will be used in a PEM fuel cell to produce 9 kW of energy. In the final stage, I need to convert this energy to city electricity using a DC-AC converter. How can I do this? I would appreciate it if you could explain it through modeling without specific values.

Hi Malik,

I see that you want to create a Simulink Model to utilize solar energy.

To achieve your objective, please follow these instructions:

1. Model a Photovoltaic (PV) System: This system should convert solar energy into electrical power. Use the SimElectronics library in Simulink to create a solar cell block.
2. Incorporate a DC-DC Converter: Add this to your model to manage voltage and current for water electrolysis, which divides water into hydrogen and oxygen using electrical energy. The DC-DC converter optimizes power transfer.
3. Model a Proton Exchange Membrane (PEM) Fuel Cell: This component uses hydrogen and oxygen to generate electricity, aiming for a 9 kW output. Adjust your model's parameters to achieve this power level.
4. Add a DC-AC Converter (Inverter): Include this in your Simulink Model to transform the direct current from the PEM fuel cell into alternating current (AC), making it compatible with the electricity grid.

This is a high-level overview, and you'll need to create the detailed models for each component.
