Tender description

This tender process is now complete. Scope of requirements is to use the models developed by EirGrid and functionality contained in the current WSAT tool or to develop a new software application. EirGrid envisages this project being a solution which will evolve over time and therefore intends awarding a contract with a potential maximum relationship of 20 years including options for renewal at various stages over the life of the arrangement. The scope of requirements is to use the models developed by EirGrid and functionality contained in the current WSAT tool or to develop a new software application to include, but not limited to: The look-ahead security assessment tool will perform power system security analysis (steady-state and dynamic) across a time horizon from real-time up to (typically) 24 hours. The tool will suggest preventive measures in cases where the security criteria (to be defined in the detailed functional specification) is not met. The tool will assess operational security components such as transient stability, voltage stability, frequency stability and thermal loading. The tool output will facilitate system operations real-time decision making, displaying results in an appropriate manner to be detailed in the tender. The tool will be based on RMS positive sequence calculations (steady-state load flow and time-domain dynamics). The time domain solver must include variable time step capability. The tool will have on-line and off-line study capability. The tool performance will be the equal, or better, to the existing WSAT tool as outlined in the background section above. The tool shall be operational in EirGrid’s Control Centres (Dublin and Belfast) by the end of 2019. The duration of the delivery contract will be up to project completion which will include for development, installation, testing, model validation, tool validation and integration of the tool in accordance with agreed programme. The services agreement will commence on the services commencement date and will be for an initial duration of 3 years with an option to extend.
