Case Study: AI-Enhanced Thermal Management in PV/T Systems
Challenge: Conventional PV systems suffer efficiency losses due to rising temperatures. Hybrid Photovoltaic-Thermal (PV/T) systems, which recover waste heat, introduce complex multi-physics interactions (heat transfer, fluid dynamics, electrical performance) that are difficult to optimize with traditional models, especially under variable environmental conditions.
Solution: Implementation of AI techniques, including surrogate modeling, digital twins, and multi-objective optimization algorithms, to dynamically manage trade-offs between electrical efficiency, thermal recovery, and system stability. AI models learn from data to predict and control these interactions in real-time.
Outcome: Integrated AI optimization significantly improved total energy yield and reduced losses in PV/T and PV-TEG systems. For example, some hybrid configurations showed improved overall performance under high irradiance and elevated temperatures, demonstrating AI's capacity to enhance system efficiency and operational reliability by optimizing cooling strategies and thermal flow control.
