Simulation and Hardware Implementation of Incremental Conductance MPPT With Direct Control Method Using Cuk Converter (2011, methodology): “Hill climbing [14], [17] is perturbation in the duty ratio of the power converter, and the P&O method [15], [18] is perturbation in the operating voltage of the PV array.”
Performance Evaluation of Parabolic Prediction to Maximum Power Point Tracking for PV Array (2011, methodology): “Recently, a new method was proposed based on the analysis and derivation of the – characteristics of a PV array by defining a natural logarithmic index [13].”
High-Performance Algorithms for Drift Avoidance and Fast Tracking in Solar MPPT System (2008, background): “To handle diverse requirements at startup and steady state, hybrid algorithms have also been proposed to improve startup dynamics [9], [10].”
Evaluation of the Main MPPT Techniques for Photovoltaic Applications (2013, methodology): “The P&O method operates by periodically incrementing or decrementing the output terminal voltage of the PV cell and comparing the power obtained in the current cycle with the power of the previous one (performs dP/dV ).”
An Enhanced MPPT Method Combining Model-Based and Heuristic Techniques (2016, background): “power point but results in slow tracking speed, while a big step size results in fast tracking but with high oscillations [8].”
