To solve the economic scheduling problem of microgrid

distributed control is usually adopted

because the physical distance between the controlled units is generally far

there may be a large communication delay

and the communication delay will reduce the distributed control precision

so a microgrid power economic allocation strategy based on optimization consistency algorithm is proposed.Firstly

the droop control information is combined with the improved consistency algorithm to realize power distribution through droop control

which can effectively overcome the delay and make the system have good convergence performance.At the same time

a cost minimization controller is designed with the consistency algorithm to control the operation of microgrid generator in real time

coordinate the output of each power source

and finally realize the power distribution under the cost minimization.Finally

the simulation results verify the effectiveness of the strategy.
