The DREAM software architecture model describes a reference class model, that aids in integrating the different components for active distribution grids. Theapplication domains, in which the framework can be used range from simulation (proof-of-concept) to implementation (proof-of feasibility). The frameworkfacilitates interoperability on the software and hardware level as well as from the communication technology level. The framework was designed from a use casesperspective. The major functionality implemented relates to flexible, heterarchic aggregation and coordination ofdevices involved in demand and supply of electricity. In the grid context aim, is to achieve a common objective, prioritize actions and operate on various timescales of grid operational and market functions. To that end, in the framework, monitoring data are handled and stored in a distributed fashion in order to directly steer or coordinate the operation of devices. These persistent dataalso allow handling forecasts and create interaction possibilities with actors or communities of actors on global and local markets and with operations in activedistribution grids and customer energy management. A first implementation is now being built
