| Abstract: |
| In the background of uncertain variables and initiative at source and load ends increasing in distribution network, thus the research of grid planning adapted to the development is of great significance. The uncertain variables and active control variables in the system are modeled respectively, the flexible methods dealing with the technical goals of economy, reliability and security are applied, and the flexible planning model of active distribution network expansion taking the source and load uncertainty into account is proposed. The solution flowchart that contains problem decoupling, simplifying flow and reverse searching is proposed. Taking the 19-bus system as an example, the results demonstrate the proposed flexible planning model and method are effective and feasible to solve the network expansion planning problem. |
