Description

technical field [0001] The invention relates to the field of distribution network planning, in particular to a two-layer planning method for an active distribution network considering the uncertainty of demand-side response. Background technique [0002] In recent years, with the increasing penetration of distributed energy resources (DER), such as distributed power generation, energy storage systems, and controllable loads, traditional distribution networks are facing challenges in terms of operational flexibility, safety, and economy. This is a big challenge, so Active Distribution Networks (ADN) came into being. The active distribution network, as a more flexible network, puts more emphasis on active planning. In the planning stage, the integrity of planning, construction and operation should be considered, and the "garbage power" of distributed power should be absorbed to the greatest extent, so as to achieve low-carbon power generation. Therefore, it has important the...
