### *3.3. Agent Based Architecture for Smart Grids*

Service Oriented Architecture (SOA) and Multi Agents (MAS) architecture are promising techniques for realizing smart grid systems. In both cases, smart grid components, such as Distributed Generators (DGs), intelligent switches, smart transformers, sensors, electric appliances, or electric vehicles, can be monitored and controlled by an autonomous software component, being either an agen<sup>t</sup> in the MAS sense or a service in the SOA sense [51]. An intelligent agen<sup>t</sup> processes several characteristics: reactivity (ability to learn the environment and act), proactiveness (self-initiative to meet expected goals), and social ability (negotiating and cooperating with other agents).
