PV array are often included in designing a PV (photovoltaic) system framework in MATLAB/Simulink. In Simulink, we provide crucial measures on how to develop a simple PV system:

Step-by-Step Measure to Design a PV System Model in Simulink

2. Then, type Simulink in the MATLAB command window and click the Enter option.
3. To design a novel framework, choose the “Blank Model” option in the main page of Simulink.

Step 2: Include the PV Array Block

2. On our framework, “PV Array” must be dragged.

Step 3: Set up the PV Array Block

1. To open its parameters, we need to double-click on the “PV Array”.
2. Depending on our requirements like module parameters, number of modules per string and number of strings, the parameters of the PV array ought to be determined.

Step 4: Insert a Power Converter (DC/DC Converter)

1. We have to select Simscape > Electrical > Specialized Power Systems > Power Electronics in the browser of Simulink Library.
2. On our model, the “Boost Converter” block or different suitable DC/DC converter should be dragged.

Step 5: Include an MPPT Controller

1. Make use of accessible blocks or we can model our personal MPPT controller.
2. Consider the basic instance: To execute the P&O (Perturb and Observe) MPPT algorithm, we can utilize the block of “MATLAB Function”.
3. Then, click User-Defined Functions > MATLAB Function in the Simulink Library Browser.
4. On our framework, the block “MATLAB Function” needs to be dragged.
5. We have to double-click on the “MATLAB Function” block. In MATLAB code, script the MPPT algorithm.

Sample code for a basic P&O MPPT algorithm:

function duty = mppt(voltage, current)

persistent prev_voltage prev_current prev_power prev_duty

if isempty(prev_voltage)

prev_voltage = 0;

prev_current = 0;

prev_power = 0;

prev_duty = 0.5; % initial duty cycle

end

power = voltage * current;

delta_power = power – prev_power;

delta_voltage = voltage – prev_voltage;

if delta_power > 0

if delta_voltage > 0

prev_duty = prev_duty – 0.01;

else

prev_duty = prev_duty + 0.01;

end

else

if delta_voltage > 0

prev_duty = prev_duty + 0.01;

else

prev_duty = prev_duty – 0.01;

end

end

duty = max(0, min(1, prev_duty));

prev_voltage = voltage;

prev_current = current;

prev_power = power;

end

Step 6: Include the Load

1. It is required to choose Simscape > Electrical > Specialized Power Systems > Elements in the Simulink Library Browser.
2. On our framework, we must drag a “Resistor” block or other capable load.

Step 7: Link the Blocks

1. To the input of the DC/DC converter, the outcome of the PV Array block should be linked.
2. The output of the DC/DC converters is meant to be connected with the load.
3. In order to manage the operating cycle, the MPPT controller has to be linked with a DC/DC converter.
4. For evaluating the current and voltage from the PV array, make use of “Voltage Measurement” and “Current Measurement” blocks and with the MPPT controller, we need to link these estimations.

Step 8: Insert Scope and Visualize Blocks

1. Select Simulink > Sinks in the browser of Simulink Library.
2. On our framework, we have to drag the “Scope” and “Display” blocks.
3. The result of the evaluation and MPPT controller must be linked with Scope. For visualization purposes, blocks have to be exhibited.

Step 9: Set up the Simulation Parameters

1. We have to click Simulation > Model Configuration Parameters from the window of Simulink framework.
2. Solver options like discrete solver and fixed-step ought to be initialized.
3. Total time of simulation must be determined.

Step 10: Execute the Simulation

1. To begin the simulation process, select the “Run” button in the window of the Simulink framework.
2. In the Scope, analyze the outcome and visualize the block in an explicit manner.
