| Abstract: |
| In order to provide a good network transmission channel for flexibility resources to respond quickly and timely to flexibility requirements, in the planning stage, fully consider the influence of network structure and planning of DG(Distributed Generation) on distribution network transmission capacity, a bi-layer optimal method for distribution network expansion planning and DG siting and sizing considering the transmission capacity of the network channel is proposed. First, the line load margin index and power flow balance index are established to evaluate the distribution network transmission capacity. Secondly, the influence factors of the transmission capacity of the network channel are analyzed, and on this basis, a bi-layer optimal model for distribution network expansion planning and DG siting and sizing is constructed, which ensures the planning scheme has good economy and transmission capacity of network channel. And a nested hybrid particle swarm optimal algorithm is used to optimize the solution. Finally, the planning method and the economic planning method are verified by examples. The simulative results show that the proposed method not only does not increase the economic cost, but also obtains a more balanced power flow, higher line load margin and better transmission capacity. |
