In order to coordinate different kinds of micro-source and conciliate the disturbances of microgrid dispatching, due to power fluctuation of wind-electricity and solar-electricity, a bi-level optimal dispatching model considering active-reactive power coordinated control is established. The first level of the model is for day-ahead schedule, which minimizes generation production cost to decide reference values of the system operation;the second level is for real-time control, employing a crossed iterative algorithm for linear programming to achieve active-reactive power coordinated control and to grantee power balance in the microgrid. A case is used to verify the proposed model and its solution. The numerical results demonstrate that the real-time control is able to decrease disturbances of the uncertainties which are not accurately considered in day-ahead schedule, and is suitable for the case of high power volatility, when voltage amplitude will not shift dramatically.
