Smart Grid (SG) is an intelligent power system that uses two-way communication and information technologies, and computational intelligence to revolutionize power generation, delivery, and consumption. Its evolution relies on the utilization and integration of advanced information technologies, which transform the energy system from an analog one to a digital one. In the vision of the SG, information plays a key role and should be managed efficiently and effectively. One of the important trends in today’s information management is outsourcing management tasks to cloud computing, which has been widely regarded as the next-generation computing and storage paradigm.
