Abstract Traditional dispatch methods based on day-ahead point forecast of wind power do not consider the uncertainty appropriately. As a result, the potential of accommodating wind power cannot be fully exploited. This paper proposes the robust unit commitment to improve the admissible region of wind power. The valid admissible region of wind generation is constructed based on the available wind generation interval. An affinely adjustable robust unit commitment model is constructed considering the electro-thermal coupling of the cogeneration systems. The proposed model seeks to maximize the admissible region and guarantees the feasibility within the admissible region. The proposed model can be transformed into the mixed integer linear programming. Finally,the proposed method is compared with the traditional dispatch method and validated using the modified IEEE 39-bus system. The simulation results verify the effectiveness of the proposed method.
