A modelling breakthrough for market design analysis to test massive intermittent generation integration in markets results of selected OPTIMATE studies

The OPTIMATE¹ platform focuses on electricity system and market designs modelling in order to assess current and innovative designs in Europe. The current paper describes the results of the first validation studies´ conducted with the tool. These studies deal with day-ahead market rules, load flexibility, cross-border management and intermittent renewable support schemes with a view to better integrating large amounts of renewable energy in Europe. Market and system designs were assessed based on economic efficiency, security of supply² and environmental impact³ indicators. These results give a promising insight into the tool and its possible future use by transmission system operators, regulators, and other public entities.
