The system comprises a data acquisition unit, a flexible parameter introduction unit and a model construction and solution unit; the method comprises the steps of determining the current operation mode of the power distribution network, and acquiring historical data corresponding to the current operation mode of the power distribution network; constructing an objective function and constraint conditions for the operation optimization of the power distribution network, and introducing corresponding flexible parameters to respectively perform flexibility treatment on the constructed objective function and constraint conditions; forming a multi-dimensional flexible comprehensive optimization model of the power distribution network operation based on the objective function and the constraint conditions which are obtained after the flexibility treatment, and importing the acquired historical data into the multi-dimensional flexible comprehensive optimization model for solving so as to obtain the optimal expected value of the current operating mode of the power distribution network. The constraint conditions in the multi-dimensional flexible comprehensive optimization model established by the method and the system are subjected to the flexibility treatment by introducing the flexible parameters, so that the boundary of the constraint conditions is flexible, and the changes of the operation structure and parameters of the power distribution network are flexiblyadapted.

Problems solved by technology

In the research on the operation mode of distribution network, due to the insufficient attention paid by people and the restriction of the configuration of existing acquisition devices, the research on the optimization of distribution network operation mode is still in its infancy

At present, there are two main deficiencies in the research on the optimization of distribution network operation mode: First, due to the use of deterministic methods to establish the optimal model of distribution network operation, and the boundaries of the feasible solutions of these models are rigid, it is difficult to deal with The changes in the distribution network operation structure and parameters make the optimal operation mode lack of flexibility; second, because only one aspect of the distribution network operation mode optimization is studied, it cannot be comprehensively studied, so the formulated optimal operation mode is inflexible; The optimal operation mode of the distribution network cannot achieve the comprehensive optimal
