Market Transparency for the Architecture of Frequency and Voltage Control under the Web-of-Cells Power Grid Structure

Market transparency is a key aspect for a well-functioning and efficient electricity market. In this paper, the concept of market transparency is addressed for the architecture of frequency and voltage control under the Web-of-Cells power grid structure developed within the European ELECTRA Integrated Research Programme. A critical review of the European Regulations on wholesale electricity market transparency issues is carried out and the related findings are tailored to the proposed architecture. The results of the analysis show that the problem of market transparency for the proposed architecture should be tackled by: Setting the qualitative requirements for data; determining the minimum data set required for the Merit Order Collection and the Merit Order Decision making; establishment of clear and specific roles for the actors regarding data and information; establishment of data placement; and setting the data set for publication.
