Thermal load calculations optimize grid capacity
Calculating the thermal load of electricity cables, transformers, and other components can lead to better use of available grid capacity. Research suggests that grid operators can achieve large potential capacity gains. Phase to Phase is therefore including these methods in its simulation application, Vision Network Analysis.
When calculating the load capacity of cables and transformers, the nominally permitted current is the criterion that is normally used. But thermal capacity is another measure. The capacity of an electricity cable or a transformer is ultimately determined by the maximum temperature that the device can handle. The ORKEST Project is researching the effects of higher thermal load on the grids. First results show that the load of cables and transformers can often be increased without any significant consequences for reliability, sustainability, or safety. The potential capacity gain in percentages runs into double digits.
Integrated into Vision Network Analysis
Phase to Phase has integrated thermal calculation for transformers and cables into Vision Network Analysis. The calculation method takes various factors into account, including environmental circumstances and grid load. Further research and more data to feed these calculations will ultimately lead to better use of the available grid capacity.
The ORKEST Project is an initiative of Stedin, Technolution, Phase to Phase, DNV, Netbeheer Nederland, and Eindhoven University of Technology.
