To eliminate the influence of large-scale access of distributed generation（DG）to the power grid and realize flexible and efficient application of multiple types of energies

the micro grid came into being.Droop control is one of the commonly used control methods for micro grids. However

this method can only achieve the active power sharing of DG unit and the reactive power sharing error is relatively large. Meanwhile

it also has some other such problems such voltage deviation and economic operation and has certain limitation. In view of the micro grid containing multiple types of DG and energy storage units in this paper

the power control strategy based on consensus theory

which contains reactive power sharing and active power optimization functions

performs effective control of each DG unit. The economic operation of the DG is achieved by the proposed strategy through the consensus control of micro-increment rate. The reactive power fast sharing of the DG unit is assured by way of the virtual impedance control. The voltage rating of the micro grid is maintained through voltage recovery control. The proposed strategy adopts sparse communication network with low construction cost. Finally

the effectiveness of the proposed control strategy is verified and analyzed by simulation and experiment.
