Empowering the Evolving Grid: From Substations All the Way to the Last Mile

As global electricity demand rises, many markets are shifting towards renewable energy sources. However, the integration of these intermittent and distributed energy sources into the grid presents significant challenges, including maintaining voltage stability, frequency control, and overall grid reliability. To address these issues, power grids must now manage increasingly complex load patterns and require swift, responsive dispatching mechanisms.

Traditionally, grid management was limited to substations. But the shifting energy landscape has necessitated a digital transformation of the grid, extending management capabilities all the way to the grid edge—right to the end consumers. This evolution highlights the pressing challenges of grid digitalization, which is explored through the lenses of utility substations, critical power, and feeder automation.

01 UTILITY SUBSTATION

Strengthen Substation Cybersecurity for the Digital Grid Transformation

Application Challenges

The transition to decentralized energy sources has increased the frequency of dispatching in modern substation networks. While traditional substations operate within closed-network systems, the integration of renewable energy now demands more complex and open communication frameworks. This evolution raises new cybersecurity challenges, exposing potential vulnerabilities in substation networks.
To mitigate these risks, substations are increasingly implementing defense-in-depth strategies, enhancing both external and internal network security.

02 CRITICAL POWER

A Unified Network Solution for Critical Power Management

Application Challenges

In critical power environments like hyperscale data centers, semiconductor fabs, and hospitals, maintaining a stable power supply and optimizing energy use are paramount.
When external substations supply power to these facilities, complex equipment must be managed via switchgear panels. In emergencies, real-time monitoring and analysis of operational voltage, current, and the status of critical equipment are vital for activating backup power sources like generators and UPSs, all within an integrated DCIM system.
The interdependence of these systems necessitates reliable communication and real-time data reporting, requiring a robust network infrastructure.

03 FEEDER AUTOMATION

Centralized Feeder Management Across Thousands of Nodes

Application Challenges

Traditionally, substations employed a reactive approach, dispatching personnel only after detecting node abnormalities. Feeder automation has transformed this process by enabling real-time monitoring and predictive maintenance through the transmission of node information back to the control center.
However, as digitalization extends to feeder levels, the large number of feeders and the use of wireless communication make them susceptible to attacks and necessitate regular firmware updates. Effective data gathering and centralized management via SCADA systems are crucial for operators.
