Multilateral remedial actions and the proposal for the cost sharing among European transmission system operators (TSOs): lessons learnt from 25.03.2013 (case study)

Abstract

The most important task for the European transmission system network operations (TSOs) is to ensure the grid security and the non-interruptible electricity supply avoiding blackouts and, at the same time, enabling the electricity trading in the Internal European Electricity Market (IEEM). In framework of TSO Security Cooperation (TSC), whose aim is to enhance the coordination among the participating TSOs, the cost-sharing principle as well as the ex-post concept of remedial actions activation analysis is to be developed. Due to the different reasons it could happen that remedial actions (such as cross-border redispatch and countertrading) are identified as necessary during the different timeframes: from capacity calculation, over the operational planning phase to close-to-real-time operation. Those measures are used for the different purposes, e.g. for guarantying physical firmness of scheduled energy transactions, maintaining the predefined voltage level and/or ensuring system security.

This paper aims to analyse the possible causes of redispatch deployment and to introduce fair cost sharing principles among TSOs for the activation of multilateral remedial actions.
