The Core Flow-Based Capacity Calculation project (Core FB DA) parties would like to inform market participants of the background of instabilities faced in the external parallel run of Core flow-based day ahead capacity calculation parallel run at the end of July and throughout August.
A multitude of unexpected issues occurred related to merging of Individual Grid Models, Non-costly Remedial Action Optimisation and the Common Capacity Calculation tool, which resulted into 19 business days with default flow-based parameters. Measures have been taken to get on track again: fixes to systems have been implemented, mitigations embedded in procedures and enhanced monitoring put in place. Since business day August 28th the external parallel run process is running stable again. Core project parties will continue close monitoring and ensure transparency to market parties.
With the start of the publication of the Core FB DA capacity calculation results in November 2020, Core project parties fulfil the obligations in accordance with Article 28(3b) of DA CCM. These obligations acknowledge that during external parallel run the processes, tools and infrastructure are further tested. The overcome instabilities were unfortunately a regression compared to the relatively stable parallel run in the months before.
Communication channels
Questions in relation to the Core FB MC project in general, the publications of the day-ahead Core Flow-Based Capacity Calculation inputs and outputs, as well as market coupling simulation results can be raised on the Q&A forum: http://coreforum.my-ems.net/
Market participants that would like to follow the project development closer, are invited to join the Core Consultative Group (CCG) by sending an email to CoreCG@magnus.nl. The participants of the Core Consultative Group will receive regular information, and invitations to teleconferences and meetings.
Best regards,
Core TSOs
