The damage caused to power grid by geomagnetic storm increases with an increase in the grid voltage level and an increase in the grid coverage area. Xinjiang is a vast, high-latitude area in China, where geomagnetically induced currents (GIC) have an enormous effect on geomagnetic storm. The voltage level of the Xinjiang power grid (750 kV) and the DC resistance of the grid are small, which aggravates the impact of GICs on the power grid. During geomagnetic storm, the safety and stability of the Xinjiang power grid is crucial. But Xinjiang power grid supplies power for a large range of area, and the grid structure is mostly connected by single transmission line. Therefore, the power grid is relatively weak in resisting accidents and has high operational risk. In this paper, Xinjiang's 750-kV power grid was chosen as a research object, and a GIC governance method (a shared governance method) is proposed. The Xinjiang power grid's control over GIC effects was analyzed, and the effectiveness of the method was verified using simulations.
