摘 要：Within this very chapter, we are going to provide a short overview on the large amount of applications and technologies involved with the IEC 61850 standard family. Starting with its origins, developed parts, and sub-parts, we will later focus on the information and communication side of this standard family and current developments in information modeling that lead to changes in how to apply the standard family. The focus of this chapter is the application of IEC 61850 in the scope of substation automation and Distributed Energy Resources and differences between those two major use cases.
