Time-Domain Analysis of the Smart Grid Technologies: Possibilities and Challenges

This chapter describes the use of time-domain analysis for the study of smart grid (SG) technologies. The studies particularly include cases of system reconfigurations by large number of switching operations, and discussions of how to exploit the advantage of automation and the self-healing capabilities of a real-life complex network. The chapter also covers the study of distributed energy resources (DERs) integration into the system and their possible effects on system voltage violations. Time-domain simulations allow for the study of issues such as power system overvoltages to be analysed in detail. Two of these studies for distribution networks having networked secondary services are discussed in the chapter. The chapter also discusses the negative impacts of distributed generation (DG) to distribution system reliability, which is of high importance to utilities. It offers some experience of the development of industrial-grade translators for interfacing power-flow programs with electromagnetic transient program (EMTP)-type programs.
