The SUMO system is a high-tech project that upgrades Slovenia’s electrical power system (EES), placing the country’s electricity transmission network among so-called smart grids. A good understanding of the current transmission capacity of power lines in terms of thermal limits allows for optimal network operation based on weather conditions.
Designing power lines is based on safe operation, which takes into account the worst possible atmospheric conditions (high temperatures, calm winds, strong sun, etc.). Since power lines can carry higher loads under normal weather conditions, it makes sense to install sensors for temperature, wind, and sunlight along the route to measure actual load values.
Using data collected from specific micro-locations and official meteorological data for Slovenia, we calculate how much the power line can be overloaded compared to its nominal value (the voltage needed for normal operation). In winter, this value can even be exceeded by 30 percent, which is very important, as energy consumption is much higher in all sectors during this season.
Calculating the dynamic load of power lines also enables significant savings in the calculation of their lifespan. With better use of existing transmission capacity, we can avoid or delay investments in new construction projects.

The calculation of dynamic load on power lines, or SUMO, allows:
- higher quality operation of the power transmission system
- increased reliability of electricity transmission due to better monitoring of the system’s performance under the influence of weather and environmental factors
- reduced maintenance and operating costs
- delayed investments in power lines and transformer stations
- increased cross-border transmission capacity
- prevention of large-scale outages, easier problem resolution.
