EMS
EMS (Energy Management System) is a computerized system used by utility companies and power grid operators to monitor, control, and optimize the performance of electricity generation and distribution. Think of it as a smart control center that helps operators keep the power grid running smoothly. It's similar to a traffic control system, but for electricity instead of cars. The system helps prevent blackouts, manages power flow, and ensures that electricity is delivered reliably to homes and businesses. Companies might also use terms like SCADA or Power Management System to describe similar systems.
