摘要:

为了更好地选择计及风电随机特性的电力系统调度计划模型,引入了3种基于风电场景的经济调度wait-and-see模型进行对比分析。从目标函数入手,对比分析“尽可能接近风电均值”和“调度计划调整量最小”这2种目标函数的差异。基于功率平衡方程,推导了3种模型制定的调度计划在应对实际可能发生的风电场景时的调节能力以及调整幅度,并进行了对比分析。最后,以IEEE 24节点系统为仿真算例,从运行成本、调节能力、调整幅度、弃风量等方面,对3种模型的仿真结果进行对比分析。分析结果表明:以调整量最小为目标的模型在鲁棒性、经济性、计算速度等方面相对于其他两个模型具有明显优势。所提供的3种经济调度模型以及对比分析结果可为运行人员灵活选择含有风电的电力系统调度计划优化模型提供参考。

Abstract:

 To make a better choice of the model of the power system dispatching plan with the random characteristics of wind power, this paper compares three economic dispatch wait-and-see models based on wind power scenario. The difference between two kinds of objective functions are compared and analyzed, which are ‘the minimum distance to the mean of wind power’ and ‘the minimum adjustment amount of dispatching plan’. Based on the power balance equation, we deduce and compare the dispatching plans obtained by three models and the regulation ability and adjustment amount for coping with the actual possibility of wind farm scenarios. Finally, taking the IEEE 24 node system as the example, we compare and analyze the simulation results of three models from the aspects of operating cost, adjusting ability, adjusting range, abandoning air volume, and so on. The analysis results show that the model with the minimum adjustment as objective has obvious advantages in robustness, economy and computation speed compared with other two models. The proposed three economic dispatch models and the comparative analysis results can provide important references for the dispatching plan optimization of the wind power system scheduling schemes.

Key words: wait-and-see model, economic dispatch, dispatching plan, wind power scenario, random characteristics
