Photo voltaic (PV) systems exhibit highly nonlinear power generation characteristics and mainly depend on environmental conditions like irradiance and temperature. Maximum power point tracking (MPPT) algorithm is essential to extract the maximum power from PV system which increases productivity. Fixed step size MPPT algorithms are extensively utilized due to their affordability and ease of usage. However, step size and frequency of perturbations affect how well the MPPT algorithm performs. Due to finite resolution of digital controller and analog to digital converters (ADC) which exhibit steady state continuous power oscillations. Improving the voltage profile of PV system is necessary which further improves the tracking efficiency and reduces power loss. Voltage reference based MPPT algorithm which equipped with feedback loop is utilized in this work, but dynamic resistance of PV system is not constant which affects damping ratio of the system. Suitable compensation is needed to reduce the ripple content of PV voltage under varying irradiance. PV integrated boost converter design and lead compensator method is implemented to improve the ripple content of PV voltage. Lastly, a simulation analysis conducted in MATLAB verifies the theoretical findings.
