Direct current sending end energy storage configuration method and system considering new energy consumption

The invention relates to a DC sending end energy storage configuration method and system considering new energy consumption. The method comprises the following steps: acquiring initial production operation simulation calculation data of a DC system and matched power supplies; setting an initial value and an iteration parameter of an energy storage configuration scheme; carrying out production operation simulation calculation on the direct-current system and each matched power supply, and calculating a corresponding wind-solar new energy utilization rate and direct-current power transmission reliability; a traversal iteration method is adopted, all energy storage configuration schemes are obtained based on the initial values and iteration parameters of the energy storage configuration schemes, and whether all the energy storage configuration schemes are alternative schemes or not is sequentially checked according to the calculated wind and light new energy utilization rate, the direct current power transmissio
