建立了基于模型预测控制的配电网多时间尺度无功优化模型，包含日前优化调节层和实时滚动调控层。日前优化侧重于运行经济性，协调配合不同类型无功设备进行大尺度无功调节，并预留充足动态无功储备响应动态调控，降低运行风险；实时滚动调控侧重于系统运行可靠性。(A multi-time scale reactive power optimization model for distribution network based on model predictive control is established, including the optimization adjustment layer and the real-time rolling control layer. A few days ago, optimization focused on operational economy, coordinated with different types of reactive devices for large-scale reactive power regulation, and reserved sufficient dynamic reactive power reserve response dynamic control to reduce operational risks; real-time rolling control focused on system operational reliability.)
