Patent ID: 10423181

Abstract:
One embodiment provides a method, including: utilizing at least one processor to execute computer code that performs the steps of: receiving forecasted geomagnetic information caused by solar activity; estimating, using the forecasted geomagnetic information, a geomagnetically induced potential for each of a plurality of transformers operatively coupled to a transmission line, wherein the geomagnetically induced potential is created by geomagnetic disturbances identified using the forecasted geomagnetic information; determining an optimized compensation voltage to be applied to at least one of the plurality of transformers operatively coupled to the transmission line, wherein the optimized compensation voltage comprises a voltage that reduces the potential difference, caused by the induced potential, between neutral lines of the plurality of transformers; and applying the optimized compensation voltage to at least one of the plurality of transformers operatively coupled to the transmission line. Other aspects are described and claimed.
