[UC47] Dynamic Line Rating Analysis
DLR continuously monitors and updates power line operating capacity based on actual conditions, reducing the need for costly upgrades and increasing grid capacity. It improves reliability, prevents overloading, and supports renewable energy integration in distribution grids.
The Utility Problem
Dynamic Line Rating (DLR) is a technique used in distribution grids to optimize the use of existing electrical transmission and distribution lines (power lines). It provides real-time information about the actual operating conditions of a power line, such as ambient temperature and wind speed, and uses this information to determine the safe and efficient operating capacity of the line.
In traditional systems, power lines are rated based on conservative and fixed criteria, such as maximum ambient temperature and wind speed. This often results in significant unused capacity, especially during periods of low ambient temperature and higher wind speed. Power lines can carry more current in the presence of moderate to high winds because the wind carries away the heat being dissipated by the power lines. On the other hand, in extreme heat and windless conditions, this static capacity can be exceeded. In very warm weather, when temperatures exceed 35 °C, the dynamic load capacity may fall below the static load capacity. In this case, the line must be loaded only according to the dynamic capacity.
In summary, the DLR is a valuable technology that can help to improve the efficiency, reliability, and sustainability of a distribution grid. For this, it is important to have a system in place that allows the calculation of DLR.
