Incremental power distribution network multi-objective optimization scheduling model based on scene method

Abstract

The invention belongs to the field of power system operation and control, and particularly relates to an incremental power distribution network multi-objective optimization scheduling model based on ascene method. The scheduling model comprises the following steps of: S1, obtaining the historical operation data and power prediction information of RDG and DR loads in an incremental power distribution network; S2, establishing a probability distribution model of RDG power generation power and DR load electricity price elastic coefficients; S3, establishing an incremental power distribution network source-load uncertainty typical scene set; S4, establishing an incremental power distribution network multi-objective optimization scheduling model considering the source-load uncertainty scene set; and S5, solving the incremental power distribution network multi-objective optimization scheduling model by adopting a multi-objective differential evolution algorithm. With the method adopted, thecoordinated and optimized operation of multiple benefit subjects is promoted; the optimization operation difficulty of the multiple benefit subjects of an incremental power distribution network is reduced; the typical scene set can fully reflect source-load uncertainty information, and can also reduce model calculation complexity; and source-network-load three-party coordinated optimization operation can be realized.

Description

technical field [0001] The invention belongs to the field of power system operation and control, and in particular relates to a multi-objective optimal dispatching model of an incremental distribution network based on a scenario method. Background technique [0002] With the accelerated development of incremental distribution network reform, the pilot project of incremental distribution network in my country has begun to take shape. Considering that the planning and construction of the incremental distribution network involves the participation of multiple entities from the source-network-load side, the actual operation of the incremental distribution network needs to take into account the interests of multiple entities, which increases the technical requirements for the coordinated and optimized operation of the incremental distribution network; in addition, Due to the uncertainty of renewable distributed generation (Renewable Distributed Generation, RDG) power generation a...

Problems solved by technology

However, for the coordinated and optimized operation of multi-stakeholders after the incremental distribution network is completed and put into operation, further in-depth research is needed.

[0004] In addition, due to the randomness of RDG power generation such as wind power and photovoltaics, and the subjectivity and randomness of power users participating in DR, the optimal operation scenario of incremental distribution network is more complicated and changeable. Therefore, how to establish the optimal operation scenario of incremental distribution network A collection of typical operating scenarios for RDG and DR loads, yet to be studied
