Automatic power flow check file generation method for power grid planning project

Abstract

The invention discloses an automatic power flow check file generation method for a power grid planning project. The automatic power flow check file generation method for the power grid planning project includes steps that 1, inputting power grid BPA initial power flow data files of two years; step 2, pre-processing data of the power grid BPA initial power flow data files of the two years, and using a maximum common sub-graph algorithm to automatically compare the data to identify BPA check data cards corresponding to the planning project; step 3, judging the topological connection relations between the BPA check data cards, and generating a plurality of planning project groups according to the topological relevance; step 4, automatically generating a BPA power flow check data file of a net rack to be evaluated. The automatic power flow check file generation method for the power grid planning project can be used for the planning and design institute to optimize planning schemes in the design process and can also be used for the power grid planning management department to objectively evaluate the power grid planning schemes of the planning and design institute.

Description

technical field

[0001] The invention relates to the field of evaluation of power system planning schemes, in particular to a method for automatically generating BPA-based power flow files (.dat) needed in power flow checking and evaluation of power grid planning projects. Background technique

[0002] In power grid planning, power flow checks must be carried out for different candidate projects proposed during the planning period. With the development of fluctuating power sources such as distributed power sources, probabilistic reliability assessment will also become an important part of future grid planning and assessment. These calculation checks and evaluations all rely on power flow analysis tools and models, and PSD-BPA is one of the power flow analysis tools widely used in China.

[0003] At present, planners rely entirely on manual modification to generate power flow calculation files for different planning levels and combinations of candidate schemes for power flow ...
