Zusammenfassung der Kapitel (Chapter Summaries)

The thesis begins with an introduction, outlining the significance of VRE in power systems and the challenges associated with their integration. Chapter 2 provides a comprehensive review of existing literature related to the reliability analysis of power systems with VRE. This chapter focuses on various reliability modeling and analysis techniques for VRE systems, including wind energy conversion systems, solar-PV systems, and hybrid VRE systems. It examines previous studies and their findings on the impact of VRE on power system reliability.

Chapter 3 delves into the reliability modeling and analysis of WECS, considering three operating concepts based on the generator's acceptable speed range. Chapter 4 focuses on the reliability analysis of solar-PV systems, exploring seven practical layouts of large-scale grid-connected systems. Both chapters provide detailed RAM analysis at the subassemblies, subsystem, and overall system levels.

Chapter 5 presents case studies and applications of the reliability analysis techniques developed in the previous chapters. These case studies illustrate the practical implementation of the methods and their impact on the reliability of VRE systems in real-world scenarios.
