| 摘 要： | 基于线性鲁棒优化方法提出了一种计及风电场出力及线路参数不确定性的电力系统安全经济调度模型,该模型计及了系统运行时风电场出力及线路参数的不确定性对线路安全的影响,利用线性鲁棒优化理论构建调度模型,并运用优化对偶理论对其进行简化。根据本文所构建的模型可得到一个不确定安全经济调度区域(USEDR),独立系统运行员(ISO)基于安全性和经济性合理确定系统扰动指标在该区域进行调度。最后,以改进的IEEE-30节点系统为例,检验了所构建模型的合理性及可行性。 |

| Abstract: | Based on linear robust optimization approach,a model was proposed for the security economic dispatch of power system considering the outputs of wind farms and the uncertainty of line parameters.The impacts of wind power output and the uncertainty of line parameters on the operating safety of power line was investigated.The theory of linear robust optimization was utilized to build the scheduling model,and then the optimization duality theory was used to simplify the model.By using this model,an uncertain security economic dispatch region(USEDR) can be obtained.Based on the security and economy,the independent system operator(ISO) can reasonably determine the system disturbance indicators to carry out the schedule in this region.Finally,by taking the improved IEEE-30 nodes power system as an example,the rationality and feasibility of the model were demonstrated. |
