In electricity networks, which term describes the infrastructure enabling two-way communication and management of power flows?

• A. Smart grid
• B. Cloud computing
• C. Microgrid
• D. Standalone grid

Answer: (A)

The bidirectional communication and dynamic control of power flows in today’s electricity networks are handled by the smart grid. It integrates digital sensors, meters, communication links, and advanced control systems so energy and information can flow both ways. This enables real-time monitoring, automated adjustments, and the integration of distributed energy resources like rooftop solar or energy storage, improving reliability and efficiency.

Cloud computing is about delivering computing resources over the internet, not the actual electrical infrastructure. A microgrid is a smaller, localized grid that can operate independently or connected to a larger grid but doesn’t by itself define the communications-enabled management of the entire system. A standalone grid refers to a grid that isn’t connected to a larger network, which still doesn’t capture the integrated two-way management capability.
