Telia Case Study
Solution for Smart Grids
As energy systems are undergoing a transition from fossil fuels to renewable energy, energy grids need to be smarter, more digitalized and more efficient. This will enable them to manage intermittent renewable energy sources, reduce wasted energy and prioritize renewable energy supply over fossil fuels. As the production of renewable electricity from wind and solar continues to grow, conventional power grids are designed for constant energy sources, which means they cannot always manage heavily fluctuating energy production.
As part of the solution, Telia are placing smart grid equipment, so-called neurons, on the electricity lines, to give grid owners real-time visibility of grid capacity by area and real-time data about their physical status. Temperature sensors within a neuron measures the temperature of the wires, allowing the owner to calculate their transmission capacity. Vibration and inclination sensors can also alert to any obstructions, as well as the location of the obstruction, such a fallen tree.
Data is sent from power lines to the cloud, enabling real-time visibility of grid capacity, ensuring that data collection and transmission happens even in the most isolated places and sparsely populated areas of the Nordic region, where communications networks may not be available.
This solution helps grid operators to; utilise the capacity of the grid more efficiently, with a 25 percent increase of power line capacity as well as the providing quick identification of faults which allows electricity from renewable sources can be prioritized over fossil fuels.
