Figure Lengend Snippet: Fig. 3. Perturb & Observe MPPT algorithm flowchart. The implementation of the MPPT Perturb & Observe Algorithm in Simulink is shown in Fig. 4. It is implemented using only Simulink blocks without using any scripting code. Each block is labelled with its function with respect to the flowchart. The P&O MPPT algorithm takes in voltage and current reading from the PV array, the previous sample (K-1) function is carried out by the unit delay block. The three if-else conditions of the P&O algorithm are carryout by the condition switch block, the ∆D block allows the user to set the perturbation step size of the duty cycle, the duty cycle increment and decrement function are carried out by an adder with a memory block D(K-1) feedback loop. The D(K) limit block limit the duty cycle exceeding the range between 0.4 to 0.6. The output of the duty cycle is connected to the battery charge controller section. The PV power output is also connected to the battery charge controller for conversion efficiency computation.

Figure Lengend Snippet: Fig. 5. Three-stage lead acid battery charge controller flowchart. The implementation of a battery charge controller in Simulink is shown in Fig. 6. The battery charge controller read in the battery voltage and SoC as input. The Simulink utilized the compare to constant block as if condition to determine if the battery SoC less than 100 %, if the condition is true it will disable the float stage by allowing the MPPT duty cycle to pass through the multiply block so that the charger enters into either bulk or absorption charging stage. If the condition is false, meaning the battery already reaches its SoC of 100 % it will enable float stage by sending zero to set the duty cycle to zero. The condition to determine the charger to enter MPPT or constant voltage charging stage is carryout by the battery voltage is less than or equal the constant voltage set-point, if the condition is true then enable MPPT charging by allowing MPPT duty cycle to pass through the MPPT/CV charging multiply block, then through the disable float stage multiply block to the PWM generator block for output to the buck converter switching device. If the condition is false, the charger enters into constant

Figure Lengend Snippet: Fig. 8. Lead acid battery charge controller performance. It can be seen that initially, the charge controller charges the battery at MPPT bulk charging stage when the battery SoC and voltage are less than 100 % and 55.4 V respectively. The charger switch to a constant voltage absorption charging stage when the battery voltage reaches 55.4 V at 15 sec. In this stage, the charge

Figure Lengend Snippet: Fig. 10. Commercial MPPT charge controller experiment setup. The validation experiment begins with recording the commercial MPPT charge controller PV input power, charging battery power and battery state of charge at 1 min interval. The recorded data is then saved as reference for the Simulink model validation. The simulated data is then compared with the recorded data for validation and performance comparison. Fig. 11 shows the validation results of PV input power, overall conversion efficiency and battery state of charge for 30 mins. It can be seen that the PV power input of the model and commercial MPPT charge controller almost overlapped with each other which indicates the model simulation PV input power is the same as the commercial PV MPPT charge controller data. The average overall efficiency performance of the PV MPPT charge controller model developed in Simulink is 98.3% which is comparable with the commercial PV MPPT charge controller recorded data with an average efficiency above 98.1%. The Simulink model has slightly higher efficiency, it could be the Simulink model environment is more ideal or can possibly cause by difference topology and components tolerance used in the commercial MPPT charge controller.
