Research and Development of BPA-DIgSILENT Power Grid Model Conversion Software

DIgSILENT/PowerFactory has a rich component library, flexible modeling capabilities, and powerful power system analysis functions widely used worldwide. BPA software is commonly used in dispatch and planning departments, but problems exist, such as poor modeling flexibility. To automatically import the power grid model of BPA into DIgSILENT/PowerFactory, this paper analyzes the static component and dynamic controller models in BPA and DIgSLENT, provides the corresponding relationship between the data conversion of two simulation software, and uses DSL language to build the mainstream controller model of BPA in DIgSILENT. We studied the DGS file provided by DIgSILENT and the Python language API interface. We designed a conversion software for automatically importing BPA power grid models into DSILENT using Python language. Finally, taking the Maozhanyang area power grid of the Southern Power Grid as an example, the component parameters, power flow calculation results, and transient analysis results of two simulation software were compared to verify that the conversion software met the design requirements.
