Renewable Energy Systems Prognostics and Health Management: A Review of Recent Advances

This paper aims to highlight the methods of predicting the future behavior of a system's health and the remaining useful life to determine an appropriate maintenance schedule. Indeed, prognostic and health management techniques dedicated to renewable energy systems with special reference to wind turbine generators and papers published in the last ten years, are presented. Therefore some applications of prognostics in renewable energy systems, including power converter devices, batteries capacity degradation, and damage in wind turbines' high-speed shaft bearings, are highlighted.
