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
