The invention relates to a power system optimization scheduling method, in particular to an active power distribution network robust optimization scheduling method considering wind power correlation. The method is characterized by comprising the following steps: firstly, constructing an elliptical uncertainty set related to wind power output correlation, then constructing an active power distribution network robust economic dispatching model, and finally solving the constructed active power distribution network robust economic dispatching model. According to the method, the ADN active and reactive power coordination robust optimization scheduling model considering the wind power output correlation is established, the conservative property of interval robust optimization is improved, a scheduling mechanism achieves a good balance effect in economy and safety, and the scheduling result is accurate. 本发明涉及一种电力系统优化调度方法，具体说是计及风电相关性的主动配电网鲁棒优化调度方法。它的特点是先构建关于风电出力相关性的椭圆不确定集合，再构建主动配电网鲁棒经济调度模型，最后对构建的主动配电网鲁棒经济调度模型进行求解。该方法
