DESCRIPTION:Historical power systems are emblematic examples of system of 
 systems. Now\, we are living a major evolution and perhaps a revolution in
  electrical grids. The term &ldquo\;smart grid&rdquo\; is used everywhere 
 without a very precise definition. The concept of cyber-physical System of
  Systems seems a good framework to capture the essence of this (r)evolutio
 n.<br> The &ldquo\;cyber&rdquo\; layer is going to play a key role in the 
 system reliability. Indeed\, more and more controls are embedded in subsys
 tems which become &ldquo\;intelligent&rdquo\; and partially autonomous. Th
 e system behavior will be imposed by the interactions between these &ldquo
 \;intelligent&rdquo\; agents driven by local pieces of software rather tha
 n by physical laws. <br> Different examples showing this trend will be pre
 sented from synchronization of inverters to aggregated game for demand res
 ponse management.<br> We must pay attention\; possible negative impacts co
 uld occur when a certain critical level of penetration of new devices and 
 processes will be reached. It is not easy\, we must review our historical 
 approach in order to specify behaviors which were yesterday imposed by phy
 sical laws and didn&rsquo\;t need any specification and which will be tomo
 rrow defined by software in local controls.<br>
