The TOTEM network innovation project NIA_SHET_0045 has developed a comprehensive PSCAD/EMTDC model of Great Britain's National Electricity Transmission System (NETS) to manage the transition towards high inverter-based generation, including wind and HVDC, aiming for Zero Carbon Operation by 2030.  
Facing challenges in sharing confidential data for Grid connection studies, a new tool is proposed. This tool would allow vendor plant owners to connect their proprietary models at designated points for EMT studies without accessing sensitive network data. It would facilitate multi-vendor participation, secure data sharing, and reduces reliance on non-disclosure agreements, streamlining the process for grid connection studies.  
This innovation enhances network stability, accelerates model validation, and supports the integration of renewables, benefiting operators, OEMs, and the broader energy sector. 

Benefits

The proposed Grid Connection simulation tool (GridConnectX)  could offer a potential solution where the entire Great Britain Electromagnetic Transient (EMT) network model remains hidden from external parties such as plant owners, consultants, and academics. Users will be granted access only to a designated connection point where they can integrate their own plant models for conducting EMT studies.  
By implementing this tool, it ensures the confidentiality of the wider network data while still enabling users to perform rigorous system analysis. It streamlines the process for grid connection studies by removing the need for extensive non-disclosure agreements with Users, thereby speeding up the approval process for new connections. Also, this tool could offer key benefits includes - enhance the EMT model quantity, early problem identification and mitigation, cost and time saving during the connection process for the users.
