The evolution of power systems toward smart grids presents a paradigm shift in the way electricity is generated, distributed, and consumed. Smart grid technologies promise enhanced efficiency, reliability, and sustainability, but their integration poses significant challenges. This paper reviews the current state of research on the challenges faced by power systems in adapting to smart grid technologies. It identifies key hurdles such as cybersecurity threats, interoperability issues, regulatory barriers, and societal acceptance. Furthermore, the paper discusses potential solutions and strategies to overcome these challenges, including advanced communication protocols, innovative grid management techniques, policy reforms, and public awareness campaigns. By addressing these challenges effectively, power systems can unlock the full potential of smart grid technologies, leading to a more resilient and sustainable energy future.
