The existing electric power grids face new challenges with the growing economies that are dependent on electricity. These challenges put the ability of the current electric power grids at risks of being able to deliver efficient, reliable and clean power energy to meet the demand of the growing economies. The reliability of the existing electric power girds during peak load conditions is ensured mainly by having excessive power capacity in the whole system [1]. Excessive power capacity necessitates turning on peaker plants which are environmentally unfriendly and also expensive. Conversely, when the average demand is much lower than the peak load, then the need for energy storage becomes a necessity. A key solution to the energy storage and wastage problems is offered by renewable energy sources; however, their integration with the existing grids comes with a set of barriers such as the intermittency of generation and the high level of distribution of the sources and the lack of proven distribution control algorithms to manage such a highly distributed generation base [2]. In such situation, the use of communication and information technologies is attractive to match the demand to the available supply and dramatically improve performance and efficiency. A smart grid is an intelligent electricity network that integrates the actions of all users connected to it and makes use of advanced information, control, and communications technologies to save energy, reduce cost and
