   • Centralized Account Management (CAM): Integration with authentication infrastructure for role-based access control.

Application Scenarios

1. Substation Automation:
   • Controls circuit breakers, disconnectors, and voltage regulators in high-voltage substations.
   • Enables seamless grid integration of renewable energy sources (solar, wind) by managing inverter-based distributed energy resources (DERs).
2. Industrial Power Systems:
   • Protects and controls large motors, transformers, and switchgear in steel mills, cement plants, and mining operations.
   • Integrates with distributed control systems (DCS) in chemical and petrochemical facilities for process optimization.
3. Grid Modernization:
   • Supports real-time monitoring and adaptive protection in smart grids with high DER penetration.
   • Manages voltage and power flow in high-voltage direct current (HVDC) transmission links.
4. Critical Infrastructure:
   • Ensures uninterrupted power supply in data centers by synchronizing backup generators and monitoring UPS systems.
   • Manages traction power substations for railways and metro systems.

Operational Advantages
