Smart grid
The smart grid is the state-‐of-‐the-‐art technology for electrical system that can sensibly execute the operations to all interconnected elements -‐ from generator to consumers. Smart grid simply converts the conventional power grid towards the modern grid in order to regulate sustainable, economic and reliable electricity (Massoud &Wollenberg, 2005 and Gellings, 2009). Smart grid intelligently executes operations from primary and secondary generators through the transmission and distribution network to the different types of consumers.
