Zusammenfassung:	The invention discloses a source-grid-load-storage collaborative optimization control method and device. The method comprises the following steps: acquiring a new energy power generation predicted value, a load predicted value and an exchange power plan value with a superior power grid after a preset time; calculating a power variation Pyc needing to be adjusted in the source network load storage system at the next moment; judging whether the system increases or decreases the output according to the power variation Pyc; if the system needs to increase the output, arranging energy storage discharge; and if the system needs to reduce the output, arranging energy storage charging. The device is used for executing the method. According to the method, the problem of stable operation control of a 100% new energy power system can be solved, energy storage charging and discharging are reasonably arranged on the basis of considering the energy storage life, the cooperative control capability of the new energy and the
