GWO algorithm-based power grid standby decision optimization method and system

The invention discloses a GWO algorithm-based power grid standby decision optimization method and system, and relates to the technical field of power system dispatching automation, and the method comprises the steps: considering the capability of a new energy unit, a DC power transmission system and an interruptible load in power grid power balance adjustment, and enabling the new energy unit, the DC power transmission system and the interruptible load to participate in power adjustment of a power grid together with conventional unit standby. And for a power grid high-power vacancy fault, establishing a power grid standby optimization cost model in which multiple resources participate, and solving a target function by using a grey wolf optimization algorithm. According to the GWO algorithm-based power grid standby decision optimization method provided by the invention, the standby range of the power grid is expanded from a single power generation side to a multi-resource standby range consisting of a source,
