Abstract：The double uncertainty of wind power output and demand response of time of use (TOU) bring great difficulty to the system operation scheduling. Based on the combination of fuzzy random chance constrained goal programming (FRCCGP) and preemptive goal programming (PGP), the paper established the bi-level dispatch model considering fuzziness and randomness of the prediction error. First of all, the paper deeply studied the uncertain factors of system operation and model the double uncertainty of the prediction error. In addition, the chance constrained goal programming was introduced to form the reserve deviation indexes. The bi-level model based on PGP identified the rigorous priority level of the safety goals and the economic goals. Finally, the validity of the model was verified with case studies and results showed that the bi-level model could optimize the operation economy on the basic of meeting the security demand.
