Enhanced adaptive control techniques for extracting maximum power from photovoltaic system
This research evaluates advanced adaptive MPPT controllers for photovoltaic (PV) systems, focusing on grid-connected setups. It compares four new adaptive control methods – PID-MRFO, Adaptive PI, Single Perceptron Adaptive PI (SP-API), and Set Membership Affine Projection Algorithm (SMAPA) – integrated with the incremental conductance (IC) algorithm. The study highlights the real-time adaptation capabilities of these controllers, especially SP-API and SMAPA, for enhanced robustness and efficiency under varying environmental conditions and partial shading scenarios.
Executive Impact Summary
The study demonstrates that SMAPA-based PI and SP-API controllers offer superior performance for maximum power point tracking (MPPT) in grid-connected photovoltaic systems. SMAPA achieves nearly ideal efficiency (~99.8%), minimal ripples (~223 W), and negligible energy losses (~0.2%) under both uniform irradiance variations and partial shading conditions. This contrasts with conventional PID and Adaptive PI controllers, which show weaker dynamic responses and higher losses, especially during rapid environmental changes. The findings emphasize the critical role of online adaptive learning mechanisms for stability and maximum energy harvesting in modern PV systems.

Adaptive control techniques are crucial for photovoltaic (PV) systems, enabling them to adjust their parameters in real-time to track the maximum power point (MPP) under fluctuating environmental conditions like varying irradiance and temperature. This ensures optimal energy extraction and system stability. The paper explores four advanced adaptive controllers (PID-MRFO, Adaptive PI, SP-API, and SMAPA) integrated with the incremental conductance (IC) algorithm, emphasizing their ability to adapt without requiring large, pre-trained datasets.
MPPT is essential for PV systems to maximize energy harvesting. Traditional methods often suffer from oscillations or slow responses to rapid changes. This research focuses on enhancing MPPT performance by integrating advanced adaptive controllers with the IC algorithm. By allowing real-time parameter tuning, these controllers overcome the limitations of fixed-gain or offline-trained approaches, leading to faster tracking, reduced power ripples, and improved overall efficiency, especially under dynamic and partial shading scenarios.
Integrating PV systems into the utility grid requires stable and efficient power delivery despite the intermittent nature of solar energy. MPPT plays a vital role in ensuring that the power injected into the grid is maximized and stable. The study evaluates the proposed adaptive MPPT controllers in a grid-connected setup, demonstrating their robustness against environmental variations and local irradiance mismatches (partial shading). This robust performance is critical for maintaining grid stability and maximizing the economic benefits of solar energy.

Performance under Partial Shading
Under partial shading conditions, conventional controllers like PID often exhibit sharp power drops and instability, failing to track the global maximum power point (GMPP). The SMAPA-based PI and SP-API controllers, however, demonstrate robust performance, effectively mitigating power drops and maintaining high efficiency. This superior adaptability to local irradiance mismatches is crucial for real-world PV applications, ensuring consistent energy harvesting even under complex environmental challenges.
