英文摘要：

An economic dispatch model for microgrid with high renewable energy resource penetration considering forecast errors is proposed.This model consists of two layers:the day-ahead schedule layer and the real-time dispatch layer.In the day-ahead schedule layer,an operational scheme for microgrid is obtained with considering the forecast errors of intermittent resources.In the real-time dispatch layer,the operational scheme is corrected in time according to the forecast errors of intermittent resources,while the voltage and the power flow are optimized.Under a high penetration of renewable resources, the proposed model can effectively correct the power fluctuation of renewable resources caused by the forecast errors. Simulation results on the study case system show that the proposed model can make full use of the renewable energy resources, while coordinating distributed generators and energy storage systems for the economic,safe and stable operation of microgrid.
