[automatically translated] This report describes the activities carried out by the dieet staff of the University of Palermo under the first phase of the research entitled "ARCHITECTURE AND LOGIC CONTROL OPTIMAL microgrids FOR ENERGY RATIONALIZATION '", covered by the Agreement Collaboration between ENEA and dieet signed on 24 February 2011. during start-up of activities, dieet and ENEA agreed: that the networks on which to develop the analysis and subsequent simulations must be existing networks in order to guide this study to a subsequent field trials. The activities were conducted in collaboration with the technical staff designated by ENEA and held both inside the premises and the dieet laboratories in Palermo, both at the ENEA research centers in Portici (Napoli) and Casaccia (Rome). During the activity, several discussion meetings and coordination with the ENEA staff were conducted. The object of the agreement of collaboration has developed in two phases. In the first stage, which constitutes the subject of this report, it has developed an analysis of the characterization of the micro architectures. In particular, the distribution network structures have been analyzed and commented currently used and their specificity in relation to the penetration of the technologies in use in microgrids. The first phase of the activities also gives an overview of polygeneration systems that are present in these electrical systems and addresses the problem of modeling of these sources within microgrids. This latter issue is closely related to the level at which are developed the logic of which is control in this collaboration agreement that concern mostly the tertiary control, which is mainly entrusted with the task of maintaining a good energy efficiency of the system. The description of the various levels to which can relate to the control and the representation of the relative architectures is still the subject of the first phase of activities. The second part of the activities is dedicated to the implementation of the control logic with a focus on software that would oversee the energy-efficient management of identified systems. After an exhaustive review that shows the state of the art on the subject of energy-efficient management of microgrids, They summarize the objectives to be attained and state variables on which action can be taken. Subsequently, it is given ample space to the solution of these technical problems in relation to technological solutions considered. The solution techniques take into account the uncertainty of the problem related to the prediction of both withdrawals by users as the meteorological variables over a period of several hours.
