A smart grid could be a promising power delivery infrastructure integrated with communication and knowledge technologies. Its bi-directional communication and electricity flow enable each utility and customers to observe, predict, and manage energy usage. It additionally advances energy and environmental sustainability through the mixing of Brobdingnagian distributed energy resources. Deploying such an inexperienced electrical system has huge and extensive economic and social edges. still, increased interconnection and integration additionally introduce cyber vulnerabilities into the grid. Failure to handle these issues will hinder the modernization of the prevailing grid. In order to create a reliable sensible grid, a summary of relevant cybersecurity and privacy problems is given. supported current literature, many potential analysis fields are mentioned at the end of this paper.
