With the growing concern of the global environment protecting and energy saving, the distributed generation(DG) is becoming an important technology to realize energy saving and ejection decreasing due to its flexibility and economical efficiency. More and more DGs access to the distribution network, which will profoundly affect the network reconfiguration. Therefore, intensive study on distribution network reconfiguration with DGs has important theoretical and realistical significance to sublimate the reconfiguration theory and improve the benefit of environmental protection..The model of distribution network reconfiguration(DNR) with DGs is established based on the time period and environmental protection effects. It can avoid the shortage of not taking into account the load curve and distribution character before. The correlation model between wind speed and load is analyzed, the nonlinear feature between them is obtained, which can improve the precision of this model. The change rule of line loss when stochastic current is injected to node is studied by considering the distribution characters of load and wind speed, which can speed up the model. The dynamic programming method is applied to solve the DNR problem. Some dimensionality reduction measurements such as effective switch combination, effective gain, line loss estimation and so on are taken to improve the efficiency of the reconfiguration model..Aiming at enhancing and improving the precision and speed of the model and algorithm, the theory and technology of the DNR model with DGs are innovated and perfected. The research production can give theoretical support to the planning, designing and running of distribution network with DGs.
