Summary: | It is important to select an appropriate representation of wind power uncertainty for unit commitment (UC). Unlike previous studies predefining the scope of uncertainty, this paper presents a method to co-optimize wind power uncertain intervals and unit commitment. The proposed method is aiming to select the optimal wind power uncertain intervals and achieve the optimal trade-off between economics and reliability in power system operation. An interval UC considering the costs of expected energy not served (EENS) and expected wind power curtailment (EWC) is modeled. Then, a reformulation and linearization method is proposed, transforming the model to a MILP problem. Numerical studies on a six-bus system and the modified IEEE 118-bus system illustrate the effectiveness of the proposed model. |
