By following these steps, you can introduce a switch function on the output of the PV array boost converter, on the grid-tied bus, and the battery storage bank using Simulink in MATLAB.
1. In the Simulink Library Browser, navigate to the "Sources" category and drag the "Step" block into the model. This block will generate a step signal that represents the switch function.
2. Connect the output of the Step block to the input of the PV array boost converter block. You can find the appropriate block in the Simulink Library Browser under the "Power Systems" category.
3. Repeat step 2 for the grid-tied bus and battery storage bank blocks.
4. Configure the Step block parameters by double-clicking on it. Set the "Time" parameter to the desired time at which you want the switch to occur. Adjust the "Amplitude" parameter to control the switch behavior (e.g., 0 for off, 1 for on).
5. Connect the output of the PV array boost converter block to the input of the grid-tied bus block, and connect the output of the grid-tied bus block to the input of the battery storage bank block.
