Gridscale X Dynamic Line Rating

Unlock your grid’s hidden capacity. Increase it by 10-15% with real-time line ratings based on current local weather and ambient conditions.

Why Gridscale X Dynamic Line Rating?

Gridscale X Dynamic Line Rating software calculates and forecasts overhead line capacity in real-time based on current local weather and ambient conditions. Increase line capacity by 10 to 15% over 90% of the time, bridging the gap between urgent capacity needs and grid extension timelines.

This modular, interoperable solution integrates into existing IT/OT workflows of grid control systems and other applications, providing flexibility without vendor lock-in. Dynamic Line Rating is compatible with Spectrum Power and the Gridscale X portfolio for better operator guidance and high grid stability.

Key benefits

Increase line capacity

Dynamic Line Rating can boost the current-carrying capacity of lines and reduce redispatching costs. When used with our Dynamic Security Assessment software, operators can evaluate problems before the thermal limit is reached.

Stay compliant

Dynamic Line Rating is in line with international standards and recommendations (e.g. IEEE, CIGRE). We can help you provide calculated ratings to regulating entities, to comply with regional requirements.

Scale as needed

Leverage general weather data, local measurements, and individual sensor data. Analyze any number of rating points, from single high voltage lines to entire grids, on sub-transmission and transmission levels.

Featured capabilities

Equipment configuration

Add relevant information during configuration to enable ratings calculation and establish connections to weather data providers. You can define different line data, a library for standard and custom conductor types is available.

Calculation and forecasting of asset ratings

Gridscale X Dynamic Line Rating calculates asset ratings up to ten days for near-term line capacity based on ambient temperature, solar radiation, conductor type, wind speed, and third-party sensor data.

Analysis of calculations

Choose from various plotting options. Access historical data from scheduled jobs showing the final rating for the respective timeframe. Compare different calculation jobs to identify critical segments per line.

Frequently asked questions

What's new in Version 1.4?

Version 1.4 comes with a significantly improved configuration of operational ratings for even more precise calculation results.

• Configure emergency and load dump ratings​ to support faster operator actions.
• Configure your weather data for more secure rating calculation.
• Set up separate scheduled jobs for different time intervals to improve capacity forecasting.

How can DLR be applied in online control room use?

Gridscale X Dynamic Line Rating enables system-wide, real-time and forecast-based ratings, seamlessly integrated into existing SCADA, EMS, and ADMS environments via open interfaces. This allows operators to safely operate with dynamic limits, reduce congestion and curtailment costs, and make better use of existing assets without compromising security.

How does DLR support in managing grid congestions?

Gridscale X Dynamic Line Rating allows operating the system based on actual operational limits considering changing weather conditions. This reduces the number of operator actions needed to redispatch the system. At the same time, higher utilization of lines allows to increase the share of renewables participating in the system.

How does DLR support the integration of renewables?

Gridscale X Dynamic Line Rating allows operators to integrate forecasts of operational limits into their short-term planning. This enables higher renewable in-feed during favorable time, for example if wind is cooling the overhead line this correlates with higher output of wind power parks.

How does DLR help defer grid capacity investments?

By bringing transparency on actual line capacity, Gridscale X Dynamic Line Rating allows to increase utilization of existing overhead lines. This relieves pressure on grid capacity expansion projects and improves prioritization of projects based on line capacity forecasts.

Which complementary extension products are available?

Gridscale X Dynamic Line Rating can be combined with

• Spectrum Power to bring actual and forecasted line ratings into the control room for improved utilization of existing overhead lines,
• Gridscale X Dynamic Security Assessment for real-time dynamic stability insights for more confident operational decision-making,
• Gridscale X Advanced Protection Assessment to assess how the protection system will react before the adjusted ratings are applied.

How does it integrate into my existing IT landscape and which interfaces are available?

We provide APIs for integration with SCADA, EMS, and ADMS systems as well as weather data providers and sensors, for exchanging rating results, equipment configuration, weather data, etc.
