Enhancing Wind Energy Efficiency with Novel Optimization Algorithm

A groundbreaking study published in the journal Environment, Development and Sustainability presents a novel approach to optimizing power extraction from wind energy conversion systems (WECS) using a combination of artificial intelligence and machine learning algorithms. The research, led by R. Kannan and his team from the Department of Electronic and Electrical Engineering, proposes a novel approach combining the Portia Spider Optimization Algorithm (PSOA) with a Multi-Component Attention Graph Convolutional Neural Network (MCAGCNN) named PSOA-MCAGCNN. This approach has been shown to significantly enhance the efficiency of WECS, achieving a power output of 2400 kW with an efficiency of 98%.

Key Takeaways:

• The PSOA-MCAGCNN approach outperforms existing techniques such as Long Short Term Memory (LSTM), Particle Swarm Optimization (PSO), and Recurrent Neural Network (RNN) in optimizing power production and reducing operational losses.
• The proposed method optimizes power production while supporting sustainable development by enhancing wind energy's role in reducing carbon emissions.
• Operational losses are reduced, with semiconductor losses reduced by 12 kW, conduction losses by 2 kW, and switching losses by 9 kW.
