This guide provides a foundation in relay functions and behaviors in current modern networks, particularly regarding renewable power sources and new electrical network structures such as microgrids. The work discusses the design and creation of protection schemes in smart grids and analyzes their impact on performance and security in protection systems. This practical book also presents a critical new coordination method for online applications.
- Reviews performance considerations and application challenges in optimizing overcurrent relays in future networks
- Provides mathematical and computational modeling scenarios for relays geared for application in future commercial equipment designs
- Describes how to adopt online protection systems by means of optimization algorithms for the adjustment and coordination of relays
- Includes pseudocodes of routines designed to support readers who are implementing or analyzing these systems
- Outlines a demonstrative virtual relay to execute programming operation and optimize coordination of relays
1st year PhD and early career researchers with interests in protective relaying, adaptive protection, resilience issues, and power system modelling; Some graduate students studying power systems engineering; Resilience and protection engineers; Utilities
