摘　　要：随着“互联网+”建设的推进,多站融合作为电力物联网建设的重要应用,亟需研究其适用于不同地区的模块化配置方案。计及储能的全生命周期寿命衰减及多站融合运营商的经济性需求,提出了一种考虑各功能子站运行特性的双层随机规划模型。首先,根据需要融合的功能子站的运行特性进行建模,确定正常运行下分布式电源的出力及负荷大小。其次,考虑长期运行过程中的源荷不确定性,根据各子模块特性采取相对应的不确定性表征和处理方法。采用双层随机优化模型对长时间尺度下的优化配置模型进行求解,将全生命周期内的运行过程等效为典型运行场景的期望值。最后,在220 kV的典型变电站场景下验证了该模型的有效性。With the promotion of"Internet+"construction,as an important application of power Internet of Things(IoT)construction,multi-station integration needs to study its modular configuration scheme suitable for different regions.Considering the life cycle attenuation of energy storage and the economic requirements of multi-station integration operators,this paper proposes a bilevel stochastic programming model considering the operation characteristics of each functional substation.Firstly,the output or load model under normal operation is determined according to the operation characteristics of functional substations that need to be fused.Secondly,considering the uncertainty of source load during long-term operation,the corresponding uncertainty characterization and processing method are adopted according to the load characteristics.The two-layer stochastic optimization model is used to solve the optimal configuration model in a long-time scale,and the operation results in the whole life cycle are equivalent to the expected values of several typical operation scenarios.Finally,the model is validated in a typical 220 kV substation scenario.
