description: The dataset of the synthetic Texas 123-bus backbone transmission (TX-123BT) system.The procedures and details to create TX-123BT system are described in the paper below:Jin Lu, Xingpeng Li et al., “A Synthetic Texas Backbone Power System with Climate-Dependent Spatio-Temporal Correlated Profiles”.If you use this dataset in your work, please cite the paper above.<br>***Introduction:The TX-123BT system has similar temporal and spatial characteristics as the actual Electric Reliability Council of Texas (ERCOT) system.TX-123BT system has a backbone network consisting of only high-voltage transmission lines distributed in the Texas territory.It includes time series profiles of renewable generation, electrical load, and transmission thermal limits for 5 years from 2017 to 2021.The North American Land Data Assimilation System (NLDAS) climate data is extracted and used to create the climate-dependent time series profiles mentioned above.Two sets of climate-dependent dynamic line rating (DLR) profiles are created: (i) daily DLR and (ii) hourly DLR.<br>***Power system configuration data:'Bus_data.csv': Bus data including bus name and location

1-72.'wind_5y' folder: Wind production for all the wind farms in the case and for all the days in the year.Each file includes the hourly wind production (MW) of all the wind plants for a day in the year.In each file, columns represent hour 1-24 in a day, rows represent wind plant 1-82.'load_5y' folder: Include each day's hourly load data on all the buses.Each file includes the hourly nodal loads (MW) of all the buses in a day in the year.In each file,columns represent bus 1-123, rows represent hour 1-24 in a day.<br>***Python Codes to run security-constrainted unit commitment (SCUC) for
