A Market System Operator as a new role to balance the distribution grid and to coordinate market and grid operations
An approach for an extended market grid operation is introduced in this paper. Therefore a Market System Operator as a new role in the electricity economy is defined and an extended ENTSO-e scheduling system is developed. Additionally a traffic light system for distribution grids is integrated. The special part of renewable energy sources with their specific character is taken into account. The aim is to retain a sustainable and reliable electricity supply system in Germany while and after the energy transition and to keep a free and liberalized electricity market as per specification from EU commission and German government. The approach helps to extend existing procedures without revising existing role models. This strengthens stakeholders and system operators as well as their communication.
