Description

This repository contains the data files the California Test System (CATS), which is a geographically-accurate, synthetic electric grid model that is located in California. This model was created using publicly available geographic data of California's actual transmission lines, substations, and power plants, which we combined with invented connections and parameters that are "realistic but not real". For more information about how this network model was created, please refer to our publication: California Test System (CATS): A Geographically Accurate Test System based on the California Grid.

The grid model is available in two formats. The MATPOWER file format is suitable for electric power system simulation and optimization. The geographic information systems (GIS) files, in .GEOJSON and .CSV formats, are suitable for geospatial analyses.

We also provide the load and renewable generation profiles that we used in the creation and evaluation of this grid. Since some of these data files exceed the size limit on GitHub, they are available in a Google Drive folder at this link: https://tinyurl.com/SyntheticCaliforniaGridData.

Usage

Clone the repository

   git clone https://github.com/WISPO-POP/CATS-CaliforniaTestSystem.git

Run a DC optimal power flow using PowerModels.jl by executing the file run_opf.jl.
