The operation of different energy sources in a MicroGrid (MG) has to be monitored and controlled by means of the Energy Management Systems (EMS) both in the grid-connected and islanded modes. In the first case, the MG can be seen as a single controllable unit by the grid operator whereas in the islanded mode the successful balance between internal load and planned generation is also required. In this paper, the architecture of an experimental MG is described. Modbus TCP/IP is used as the communication protocol in the MG to receive data and send commands to different components within the system, and monitoring by means of cabled signals is performed. Furthermore, in order to efficiently cater for electric and thermal demand, a central EMS is aimed to evaluate different procedures for the day-ahead scheduling of a MG. In particular, operational planning is proposed and applied to a selected configuration of a testbed facility at Politecnico di Bari. Grid-connected as well as stand-alone configurations are tested.
