摘 要:由于风电具有很强的随机性,风电以及风电功率的预测都有难度,因此给含风电的电力系统经济调度带来了很大困难。根据风电间歇性和随机性的不同处理方法以及旋转备用和风险对目标函数的约束,从模型以及求解方法两个方面考虑风电接入下的电力系统经济调度问题,分析了模型的优势与不足,从寻优速度、精度和收敛性比较了各种算法的优缺点,讨论了模型使用各种算法解决问题的方法和途径并指出风电接入下的经济调度问题将来所面临的工作。

Abstract: Wind power is with very strong randomness, wind power and its power are all difficult to predicate, thus it is difficult for power network containing wind power to carry out economic dispatch. According to different treatment methods of wind power intermittent and randomness, and the target function binding from spinning reserve and risk, this paper considered power system economic dispatch issue from the model and solution method. Analysis was made to advantages and insufficiency of the model. Various algorithms were compared from aspects of searching optimized speed, accuracy and convergence. Discussion was made to the methods and ways solving problems with various algorithms. It is pointed what the economic dispatch issue under the wind power connected-in will confront with in the future.
Key words: power system; wind power; economic dispatch; spinning reserve
