The method includes following operations. A bus real-time operating voltage and a collection line current of a monitoring point of the renewable energy power system are collected; a system's Thevenin equivalent potential of the monitoring point is calculated according to the bus real-time operating voltage and the collection line current; a short circuit ratio of the monitoring point and a critical short circuit ratio of the monitoring point are calculated according to a nominal voltage of the monitoring point, the system's Thevenin equivalent potential and the bus real-time operating voltage; a safety margin of the short circuit ratio of the monitoring point is calculated according to the short circuit ratio of the monitoring point and the critical short circuit ratio of the monitoring point; and a strength division result of the voltage support strength of the renewable energy power system is determined according to the safety margin of the short circuit ratio of the monitoring point and a set voltage support strength division criterion. The method greatly reduces electrical parameters involved in the calculation of the short circuit ratio, improves algorithm efficiency and provides technical support for strength division of the voltage support strength.",
