The development of this book required writing a multicore solver for Windows to demonstrate the performance of the partitioning method presented herein. Such program requires implementing several time domain simulation concepts not always transparent to users. This chapter introduces such concepts and their notations. In addition to what is presented in this chapter, readers are referred to numerous good books and papers in the area of time domain simulation. Excellent resources to learn power system simulation theory are the books written by H. W. Dommel and N. Watson and J. Arrillaga. Not much theoretical background in time domain simulation is assumed to follow the discussion presented in this chapter. Instead, this chapter was written to provide a foundation of key principles required to develop a time domain solver that can address intermittent high-frequency switching actions.
