A Smart Grid is an electricity network that can cost efficiently integrate the behavior and actions of all users connected to it – generators, consumers and those that do both – in order to ensure economically efficient, sustainable power system with low losses and high levels of quality and security of supply and safety….
The Smart Grid concept deployment is driven by three technologies: distributed generation (DG), energy storage systems (ESS) and the demand side management (DSM). These three technologies grouped under the name of Distributed energy resources (DER) are changing the operation paradigm of the electricity grid.
