Abstract: To deeply explore the interaction among electricity market operation, market entity decision-making and power grid dispatching operation, the electricity market joint experiment inference ability is established. Also, the overall function framework of the full-scope experiment platform for electricity market is constructed, and the main challenges of electricity market experiment inference under the“carbon emission peak and carbon neutrality”goal are systematically expounded. The intelligent construction technology of experiment inference scenario and the simulation technology of bidding decision behavior for multi-type market members are proposed. The key technologies that need to be further broken through are emphatically analyzed from the perspectives of high-performance intelligent clearing algorithm, multi-market coupled operation simulation and long-period continuous simulation task scheduling for electricity market clearing simulation. The key points of the simulation technology for power grid dispatching operation connected with electricity market operation simulation and big data evaluation technology for market operation are put forward.
