Design and comprehensive analysis of adjustable step MPPT controllers for solar PV systems under stochastic atmospheric conditions

At present, power transmission systems are moving to renewable sources because their features are more reliable, easy to install, increase public health, and lower development costs when associated with conventional energy systems. Here, solar technology is considered because of its advantages when equated with other renewable sources are free energy production, good energy density, low air pollutants, and less maintenance requirement. In this article, a triple diode cell technology is considered for achieving the accurate voltage of the PV, and its power production is increased by proposing the Adjustable Cuckoo Search Methodology (ACSM). Here, the ACSM is studied by comparing it with the other swarm and conventional Maximum Power Point Tracking (MPPT) methodologies. The proposed MPPT controller tracks the MPP with 0.025 s time duration at 355 K. Finally, the one-switch non-isolated voltage improvement DC-DC circuit is used in the proposed system for giving the wide voltage gain to the consumer loads. The proposed ACSM-fed DC-DC converter system is investigated by utilizing the MATLAB/Simulink tool and the converter is investigated experimentally by applying the programmable power source.
