Maximizing utilization of the transformers using Dynamic Thermal Rating

The low-voltage distribution grid is facing a rapid peak load growth, mainly due to the massive transition to electric heating and the increasing integration of electric vehicle charging infrastructure. The pace of emerging problems, given the massive integration of renewables, drives the development and utilisation of Dynamic Thermal Rating (DTR) technology to gain an extra load band while leaving operational safety intact. DTR is a system operation concept aiming at maximizing utilization of the equipment (power lines, transformers) when weather conditions allow it, without compromising the safety of operation and without a negative impact on the life expectancy of the equipment.
