Establishing a solid basis for Smart Grids requires the cooperation of Wide Area Meter Systems (WAMS), state estimation, and technology for communication and information (ICT). Although the accuracy and dependability of power grid information are improved by these technologies, their integration raises certain possible security risks that need careful consideration. Because of the complex interaction between ICT and the power system, new approaches are needed to model the intelligent energy system as a Cyberspace Physical System and analyze the effects of ICT errors on the electrical grid's operations. This research presents a novel methodological technique to evaluate the reliability of a 5G-based WAMS by using numerical computing and modeling with Stochastic Activity Networks. The research takes into account both external issues, such rain impacts, and internal ones, like component failures, and assesses how these affect the WAMS's capacity to provide reliable data for power network condition estimates. A 5G-based WAMS shows near-ideal performance in comparison to other state estimate methodologies and weather circumstances, highlighting its potential for use in Smart Grid maintenance applications in the future.
