Summary:The uncertainty and volatility caused by the current high proportion of distributed generation access have brought new challenges to the economy and security of distribution network. Therefore, a Two-layer optimization method of web of cells network is proposed, which considers the uncertainty of source and load. Firstly, the flexibility of various source-load in the distribution network are considered, and the flexibility evaluation index is established from the flexibility supply and demand balance and branch channel adequacy. Secondly, a Two-layer optimization model of distribution network considering economy and flexibility is established. The upper model takes the grid division strategy of distribution network as the decision-making subject, and the lower model takes the flexibility of supply and demand side to adjust the output of resources as the decision-making subject. Finally, the simulation results verify the rationality and effectiveness of the proposed optimization method.
