In this modern world, traditional grid has now become a “stupid,” ineffectual and environmentally extravagant system, because it is fundamentally a one-way channel system. The power distribution system cannot receive immediate information if the electricity is terminated at the customers’ end. The grid is incompetent to bear maximum load if it exceeds its projected demand. Moreover, it is not suited to integrate with decentralized/localized and renewable power generation sources. Therefore, traditional grid does not have sufficient capacity to fulfill the increasing demand for electricity.
