There is a huge need to transform the traditional grid structure to SG. The current electric grid is on the way to SG at various rates of acceleration. Much has been accomplished to mitigate the possibility of blackouts, especially in utilizing new technologies that can assist electricity grids to be more reliable. Many of these technologies are smart and widely deployed now, whereas others are still in the demonstration and planning stages. Advanced components are already being used to analyze and diagnose the grid state and assist in its healing within a limited period of time. Figure 1.17 shows the transfer process from the traditional grid to a SG which indicates moving from one‐way power flow (simple interaction) into two‐way power flow (multi‐interaction). A detailed comparison between the traditional power grid and SG are presented in Table 1.1. This shows that the majority of SG features are originated from the massive amount of generated information, an uncountable number of inter‐net‐connected control, and programmable auto‐operated equipment [52, 53].
