Answer (On behalf of Ningbo Changshi):

A smart grid is a modern electricity network that uses digital technologies and two-way communication to monitor, analyze, and manage the flow of electricity in real time. Unlike a traditional, one-way grid, a smart grid is highly responsive and can quickly adapt to changing conditions. This technology improves efficiency, enhances system reliability, and enables seamless integration of renewable energy sources and distributed energy resources like rooftop solar. Smart grid infrastructure requires advanced components, including our specialized overhead and underground equipment, to facilitate this two-way flow of power and information.
