GB Transmission Network Data

This dataset provides a comprehensive representation of Great Britain’s (GB) electricity transmission network. It is designed for researchers, engineers, and policymakers focusing on power system analysis, network planning, and the integration of renewable energy technologies.

The dataset is organised into multiple sheets, with each sheet representing a specific type of network device or component. The rows in each sheet correspond to individual devices, and the columns provide detailed specifications and attributes for those devices. Below is an overview of the dataset structure:

1. Terminals:
2. • Columns include: Name, Voltage (kV), Latitude, Longitude.
   • Details the geographical and electrical characteristics of network nodes.
3. Transmission Lines:
4. • Columns include: Terminal i, Terminal j, Length (km), R1 (Ω), X1 (Ω), Rated Voltage (kV), Nominal Current (kA), B1 (µS), C1 (µF), B0 (µS), C0 (µF).
   • Captures physical and electrical properties of transmission lines.
5. Transformers:
6. • Columns include: Name, HV/LV sides, Snom (MVA), Tap Position, r (p.u.), x (p.u.), b (p.u.), r0 (p.u.), x0 (p.u.).
   • Provides technical specifications and operational parameters of transformers.
7. Static Generators:
8. • Columns include: Name, Plant Category, Subcategory, Active Power (MW), Apparent Power (MVA), Maximum Power (MW), Maximum Reactive Power Limit (Mvar).
   • Includes information about renewable and non-synchronous generation sources.
9. Synchronous Generators:
10. • Columns include: Name, Plant Category, Subcategory, Active Power (MW), Apparent Power (MVA), Max Active Power Limit (MW), Max Reactive Power Limit (Mvar).
    • Describes synchronous generation sources.
11. Demand:
12. • Columns include: Terminal, Active Power (MW), Reactive Power (Mvar).
    • Specifies electricity demand at different nodes for the peak winter 2024.
13. Shunt Devices:
14. • Columns include: Name, Type, Rated Voltage (kV), Rated Reactive Power (Mvar), Upper Voltage Limit (p.u.), Lower Voltage Limit (p.u.).
    • Represents devices used for voltage regulation and reactive power compensation.
15. SVC (Static VAR Compensators):
16. • Columns include: Terminal, Q of Reactance (>0) (Mvar), Rated Reactive Power (Mvar), Target Voltage (kV).
    • Details reactive power management devices.

This dataset was created using validated models and publicly available data. It serves as a foundation for power system studies, including grid reliability analysis, congestion management, renewable integration scenarios, and etc.

The research results derived from this dataset have been published in the Applied Energy Journal in the paper titled "Addressing Electricity Transmission Network Congestions Using Battery Energy Storage Systems – A Case Study of Great Britain." This publication explores the potential of battery energy storage systems to address congestion challenges in GB’s transmission network.
