This research looks at how different levels of spending affect the safety of the power system and the automation of substations.  Power networks are facing more and more cyber and physical dangers, such as SCADA hacks and cascading breakdowns, as they rely more and more on digital control and tracking systems. The study looks at low, medium, and high spending plans using cybersecurity risk score models and dynamic stability tests in MATLAB/PSCAD. The results show that higher spending greatly lower risks, make systems more reliable, and boost the efficiency of automation. The results make it clear how important it is to keep giving focused funds to make sure that energy systems are strong, scalable, and ready for the future so they can handle new security problems.
