摘要 基于日前风电功率点预测的传统调度方法没有充分地考虑风电不确定性,难以有效挖掘电热联合系统的风电消纳能力。该文提出提升风电消纳区间的鲁棒机组组合优化方法。基于可用风电功率区间,构建有效的风电功率允许出力区间。基于仿射策略,考虑供热机组电热耦合等约束,建立鲁棒机组组合模型,优化风电消纳区间,对于风电消纳区间内任意可能的风电波动,该模型均能保障调度策略的可行性。所建模型可转换为混合整数线性规划进行求解。最后,在修改的IEEE 39节点系统上进行测试,并与传统调度方法对比,验证了所提方法的有效性。

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.
