Interconnectors

Not currently included in the model. More information on existing and future interconnectors is available from OFGEM.

I think that there are 2 approaches possible:

1. Assume each connected country is another node. Then, use historical data to fix import/export in previous years, and assume simplified load and generation mixes of connected countries for future. Note, this ignores effect of internal markets and interconnectors of connected countries to further countries.
2. Run something like a clustered PyPSA-Eur model to generate import/export interconnector flows to be used as exogenous inputs to the GB dispatch. BUT would still need to assume simplified load and generation mixes of countries for future, or spend time digging into future energy scenarios, assuming they exist, for included countries.

This second method has been applied here where Aurora use their own European-wide model to get interconnector import/export profiles to be used in power dispatch model - https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/943239/impact-of-interconnectors-on-decarbonisation.pdf

Interconnectors included using historical data

[andrewlyden]

Interconnectors included as HVDC links. Fixed marginal cost based on assumption on main generation type of connected country. The marginal cost can be included as a time-series as future work...
