The concept of a smart grid is a modernization effort that moves away from a traditional one-way power flow to a bidirectional system. It uses digital technology, sensors, and communication to improve the efficiency, reliability, and security of the electrical grid. This is particularly important for integrating intermittent renewable energy sources. Key changes include:

• Bidirectional Power Flow: The grid must now handle electricity flowing from homes and businesses back into the grid, requiring new control systems and components.

• Enhanced Reliability: Smart grids can detect and respond to outages more quickly, often "self-healing" to restore power.

• Integration of Renewable Energy: The smart grid is essential for managing the variable output of wind and solar farms, ensuring grid stability.

Ningbo Changshi provides the foundational tools and equipment needed to build and maintain the physical infrastructure that supports this intelligent, modernized grid.
