Abstract-Future energy systems require decentralized regulatory approaches. Aggregates, equipped with appropriate sensors, can behave independently for the purposes of system stability. To explore and evaluate appropriate control mechanisms a multiagent-based simulation will be developed. It enables realistic simulations of electricity grids and decentralized consumption, storage and production units as well as provides the basis for further research whether the concept in scale could be successful. We describe the general architecture of such a simulation approach in comparison to existing literature.
