Problems solved by technology

[0004] In order to overcome the existing active distribution network planning scheme, the present invention does not consider the interaction mode between power supply and users, and only limitedly considers the impact of demand response resources on planning, and it is difficult to reasonably consider the corresponding changes on the user side in the actual operating state For the problem of the impact on planning, a two-layer planning method for active distribution network is provided that takes into account the interactive response of source and load, which makes up for the unreasonable deficiency of active distribution network configuration, enhances the coordination between the source side and the user side, and realizes Coordinated optimization on both sides of the source and load, and considering the interactive response process in the planning stage, established a distributed power double-layer programming model that takes into account the interactive response of the source and load, and conducted solution analysis to provide in-depth guidance for the planning and construction of active distribution networks

Description

technical field [0001] The invention relates to the technical field of distribution network planning, in particular to a two-layer planning method for active distribution network considering the interactive response of source and load. Background technique [0002] In recent years, a large number of renewable energy sources have been connected to the distribution network and demand-side response resources have become increasingly abundant, which has brought different impacts on the dispatch and operation of the distribution network. The increase in controllable resources has also improved the flexibility and Complexity, the traditional distribution network dominated by passive control is obviously not compatible, so it is urgent to transform the traditional distribution network or build a new active distribution network. [0003] In the process of the active distribution network gradually developing and gradually replacing the traditional distribution network, a large number...
