In this context, the microgrid concept adds value to distributed energy resources (DER) by aggregating them into autonomous grids that provide high levels of efficiency, security and controllability. In order to achieve its functions, a microgrid requires a control system in charge of operating the elements in it in an optimal way while the required quality parameters are fulfilled. This paper describes the general architecture of a microgrid energy management system (EMS) based on multi-agent system (MAS) technologies. MAS technologies are considered to be very well suited to systems that require plug and play capabilities, robustness, heterogeneous device integration, high scalability and extensibility. All of which are essential characteristics of a microgrid EMS. This paper also describes the implementation of a secondary control system based on the microgrid EMS architecture developed. This system is in charge of maintaining microgrid frequency and power exchange with the main grid close to predefined values. This is achieved in a way in which generation and consumption resources are optimally dispatched and able to operate in both grid connected and islanded modes. Finally, the control system developed is tested in an actual microgrid in order to assess its performance and demonstrate its applicability.17enginfo:eu-repo/semantics/restrictedAccessjournal article10.1002/etep.443distributed energy resourcesenergy management systemmicrogridmulti-agent systemssecondary controlEnergy Engineering and Power TechnologyElectrical and Electronic Engineeringhttp://www.scopus.com/inward/record.url?scp=79953246604&partnerID=8YFLogxK
