Objectives	Manitoba Hydro International (MHI) is a world leader in power system simulation and has developed a way to study electromagnetic transient (EMT) behaviour on large systems, like the full GB transmission system, using the PSCAD simulation software. This project proposes to have MHI develop and validate a full-scale model in PSCAD for the GB transmission system. The project scope will be to; Develop PSCAD Models of the GB transmission system across the three licence areas;Develop new tools for automatic reduction of the PSCAD model to produce both static and dynamic equivalents of the reduced areas;Develop new tools for configuration and quick initialisation of the EMT models to support future work by the Transmission Owners (TOs);Determine the detailed requirements and establish shared computing resources that provide the TOs with a facility that can be used to conduct the most detailed and computationally intensive studies of the full GB system;Perform illustrative studies based on the developed PSCAD network including;- sub-synchronous resonance investigations- control instability studies- switching studies on a selection of substationsParticipate in a knowledge transfer workshop to provide the TOs with the capability to use the models, extend them as required in the future, and perform a range of studies. The objectives of the project are as follows: Build and validate a PSCAD model of the GB transmission network and from that derive separate models for each of the three TO licence areas; Deliver tools for PSCAD model manipulation and analysis that will support the TOs in their use of the GB model;Provide the GB TOs with the knowledge and understanding required to adopt the models and put them into use; and Establish shared computing resources for running the most complex models.
Abstract	The GB power system is rapidly evolving as conventional synchronous generation is decommissioned and ever greater levels of renewable sources are connected leading to a much lower level of system inertia and lower short circuit levels. At the same time there are increasing numbers of HVDC links and Flexible AC Transmission systems (FACTs) devices being connected in close proximity in parts of the system. The potential for adverse control interactions between these devices is rising and needs careful consideration within the context of a potentially weaker GB system. Conventional phasor-based RMS simulation tools have limitations in studying weak, low inertia systems due to the level of detail that is represented. A move to developing more detailed electromagnetic transient (EMT) based models which will address these concerns is proposed as a solution and is seen as a key way of de-risking the integration of the technologies described above.
