Modelling short-term electricity markets and assessing impacts of energy policies with the OPTIMATE prototype simulation platform

The OPTIMATE prototype performs simulations involving multiple market areas and heterogeneous market rules. The platform models the sequence of actions conducted by Market Players, Transmission System Operators and Power Exchanges from day-ahead to real time. The recent developments of the platform include intraday and real-time processes with various balancing mechanisms. It enables thus to compare implicit and explicit balancing strategies. Most of the time, implicit balancing is more efficient than explicit balancing. Some results of recent market design studies performed with the day-ahead module of OPTIMATE in the framework of the Market4RES project are also put forward.
