Method and system for judging thermal power-stored energy adjustment demand in high-proportion new energy system

The invention discloses a thermal power-stored energy adjustment demand determination method in a high-proportion new energy system. The method comprises the steps of obtaining data information of a target power system; constructing a power balance expression; judging the electric quantity balance state of the target electric power system in the typical day; constructing a power demand constraint condition when the target power system meets the peak load; constructing a supporting power supply capacity benefit index and a supporting power supply capacity substitution benefit index; and completing determination of thermal power-energy storage adjustment requirements in a high-proportion new energy system. The invention also discloses a system for realizing the thermal power-stored energy adjustment demand determination method in the high-proportion new energy system. According to the method, through the innovative judgment process and calculation indexes, judgment of the thermal power-stored energy adjustment
