Substation Automation and Renewable Integration for Efficient Power Management - Lanner Electronics | Network Appliance | uCPE SD-WAN| MEC Server | Intelligent Edge Appliance

Modern electrical grids are under pressure to maintain stability and efficiency while absorbing increasing amounts of renewable energy (solar, wind, etc.). Utilities need to modernize their substations and edge installations so they can handle bidirectional flows, real-time control, and interoperability among legacy and new equipment.

Challenges

• Variability of Renewable Output: Solar/wind generation fluctuates, causing voltage/frequency stability challenges.
• Protocol Heterogeneity: Renewables often use different protocols (Modbus, proprietary, etc.), while substations and modern IEDs use IEC-61850.
• Reliability & Availability Requirements: Substation control systems need minimal downtime, deterministic performance, fast failover.
• Harsh Operating Conditions at Edge: Outdoor or semi-outdoor installations (e.g. renewable sites) must handle temperature extremes, vibration, dust, etc.
• Security and Standard Compliance: Need to meet grid operator/utility regulatory requirements, secure communications, data integrity, etc.

Lanner’s Solution

ICS-P770 for Substation Automation

A ruggedized, IEC-61850-ready substation automation computer that manages protection, control, and communications inside the substation.

• 3U Rugged rackmount computer designed for substation control and protection.
• Fully supports IEC-61850, modern relays, IEDs, and protocols such as GOOSE/MMS.
• Supports PRP/HSR redundant networking to ensure zero packet loss and uninterrupted data flow.
• Offers high-performance computing for real-time analytics and substation automation applications.

IIoT-I330 for Renewable Energy Automation

• Compact fanless platform optimized for solar and wind farm integration.
• Acts as an edge controller to connects to local equipment such as inverters, string combiner boxes, and environmental sensors (irradiance, wind speed, temperature).
• Provides pre-processing at the edge, including data aggregation, filtering, anomaly detection, and forecasting.
• Wide-temperature and rugged design for outdoor renewable environments.

Benefits

At the renewable plant, the IIoT-I330 connects to inverters, string combiner boxes, and weather stations, standardizing data and securely transmitting it to the substation.

Within the substation, the ICS-P770 receives this renewable input, synchronizes with SCADA/EMS, and manages load balancing with the support of PRP/HSR redundant Ethernet for high reliability.

For the grid operator, unified data from the ICS-P770 enables predictive load management, real-time fault detection, and optimized dispatching of both renewable and conventional energy resources.

Conclusion

By combining ICS-P770 for substation automation and ICS-P371 for renewable integration, Lanner provides utilities with a resilient, standards-compliant solution for efficient power management. This approach empowers grid operators to balance renewable variability, protect critical infrastructure, and move toward a smarter, greener energy future.
