The invention discloses a precise load control system and method based on a stability control technology. The system comprises load shedding control terminals, control substations and a load control main station, wherein the load shedding control terminals acquire sheddable loads in real time, carries out classification according to the importance of the loads and uploads the sheddable loads to the control substations; the control substations classify and summarize the sheddable loads; the shedding priority is set in view of the control terminals respectively, and the total amount of each class of sheddable loads is uploaded to the load control main station; and when the load control main station judges quick drop or interlock of feed-in DC power, the total amount of sheddable loads is calculated, a load shedding command is sent to the control substations, the control substations send load shedding commands to the load shedding control terminals according to the shedding priority, andthe load shedding control
