DG planning method for 10kV distribution network considering transfer of power supply

With the widespread application of distributed generation (DG) in 10kV distribution networks, existing DG planning schemes are difficult to adapt to the complex practical operation scenarios of distribution networks. This article proposes a 10kV distribution network DG planning method that takes into account the current situation. This method is based on the tolerance penetration ratio (TPR) of distribution network DG and the actual requirements of distribution network operation and transfer of power supply. A distribution network transfer model of power supply is established, and the TPR of each ring network group line is calculated using this model in different extreme supply scenarios, forming a recommendation table for the TPR of each ring network group line, which has practical guidance significance for distribution network DG planning. Finally, the effectiveness and accuracy of the method were verified through numerical examples.
