PSO Trained ANFIS MPPT for Solar PV system

PSO Trained ANFIS MPPT for Solar PV system

In this Work, an ANFIS technique using experimental data is designed for predicting the maximum power point of a photovoltaic array. An ANFIS model training strategy is challenging due to the variations in the training and the operation conditions of a photovoltaic system. In order to improve ANFIS model accuracy, the Particle Swarm Optimisation (PSO) algorithm is utilized to find the best topology and to calculate the optimum initial weights of the ANFIS model. Hence, the dilemma between computational time and the best-fitting regression of the ANFIS model is addressed, as well as the mean squared error being minimized. To evaluate the proposed method, a MATLAB/Simulink model for an installed photovoltaic system is developed. The results show that the optimized feedforward ANFIS technique based on the PSO algorithm using real data predicts the maximum power point accurately.

Introducing PSO Trained ANFIS MPPT

Maximum Power Point Tracking (MPPT) is an essential feature of solar PV systems that allows them to operate at their highest efficiency by constantly adjusting the load to extract the maximum available power from the solar panels. Traditional MPPT techniques like Perturb and Observe (P&O) and Incremental Conductance (IncCond) have been widely used, but they may suffer from slow tracking speeds and accuracy issues, especially when dealing with rapidly changing environmental conditions.

The Basics of Particle Swarm Optimization (PSO)

PSO is a nature-inspired optimization technique based on the collective intelligence of a swarm of particles. Each particle represents a potential solution and explores the search space to find the optimal solution based on a fitness function. The particles communicate with each other, sharing information on the best solutions found, leading the entire swarm towards the most promising regions of the search space.

The Fundamentals of Adaptive Neuro-Fuzzy Inference System (ANFIS)

ANFIS is a hybrid computational model that combines fuzzy logic and neural networks to create a powerful decision-making system. Fuzzy logic handles imprecise and uncertain information, while neural networks are responsible for learning and adapting to patterns in the data. ANFIS is capable of approximating complex functions and mapping inputs to outputs efficiently.

Integration of PSO and ANFIS for MPPT in Solar PV Systems

By integrating PSO with ANFIS, we can create a robust and adaptive MPPT algorithm for solar PV systems. The PSO algorithm optimizes the parameters of the ANFIS model to track the maximum power point accurately, even under rapidly changing atmospheric conditions. This combined approach ensures superior tracking performance compared to traditional MPPT techniques.

The PSO trained ANFIS MPPT algorithm can swiftly and accurately respond to changes in solar irradiance and temperature, maximizing energy extraction from the PV panels. This capability significantly improves the overall energy yield of the solar PV system, making it highly efficient.

Robustness and Adaptability to System Changes

Traditional MPPT methods may struggle when dealing with partial shading or sudden changes in environmental conditions. However, the PSO trained ANFIS MPPT excels in such scenarios due to its adaptive nature and robustness, ensuring optimal performance even in challenging conditions.

Increased System Efficiency and Overall Performance

The superior tracking speed and accuracy of the PSO trained ANFIS MPPT translate to improved system efficiency and enhanced overall performance. This not only benefits individual users but also contributes to the grid's stability by injecting higher-quality power.
