Fast-changing smart grids have transformed the energy business by enabling real-time tracking, automation, and electricity sharing.  However, digitisation has caused data security challenges including hacking, leaks, unauthorised access, and privacy concerns. This study examines smart ways to improve data security in smart power networks using contemporary technology and strong legislative frameworks. The study also examines policy-driven measures such obeying rules, global safety standards, and multi-stakeholder governance structures to assure responsibility and resilience. Technology and politics must collaborate for smart, flexible safety. The results show how crucial it is to keep an eye on dangers, collaborate with all stakeholders, and invest in cybersecurity to protect critical power resources.
