Abstract: As the existing system fails to evaluate the process of pushing the power grid dispatch control

instructions，the push delay and energy loss increase. A feature selection-based automatic push system for power grid dispatch control commands was proposed.According to the characteristics of power grid dispatch control commands，the automatic push process of control commands was evaluated in multiple dimensions. Hierarchical classification of power grid dispatching instructions by feature selection method. The instructions were analyzed in multiple dimensions，the transmission power of matching nodes were added，and the automatic push model of operating instructions was built，and the instructions were transmitted at different levels. On the basis of the above，combined with the requirements of the system，a design scheme for the automatic push system of power grid dispatching control commands was given，and the working process and task modules of the system were analyzed and introduced in detail. Experimental tests prove that the designed system can effectively reduce the push delay and energy loss，while the packet loss rate and congestion time are also reduced accordingly.
