The new course of FITs mechanism for PV systems in Italy: novelties, strong points and criticalities
2011
The paper deals with the new course of the Feed-in Tariffs mechanism for photovoltaic systems that will start from January 1, 2011 in Italy with the actuation of the Government Decree DM 06/08/2010. After a short introduction on Feed-in Tariffs and Net-metering in Italy, the paper focuses the attention on an economical comparison between the incentives established by the Government Decree DM 19/02/07, ended on December 31, 2010 and those introduced by the DM 06/08/2010. The economical comparison is based on three indexes: the Pay Back Period, the Net Present Value and the Internal Rate of Return, characterizing the investments done for the realization of the photovoltaic systems. In particu…

Monitoring of renewable energy prototype for the DEDUENERT research project
2016
In this paper, we present a renewable energy sustainable micro-system installed upon a platform located in the Research and Technology Centre of Energy in Borj Cedria Techno park (Tunisia). This prototype has been conceived within the ENPI (European Neighborhood and Partnership Instrument) cross-border cooperation Italy-Tunisia 2007–2013 research project framework. This project's overall goal is to develop a common strategy for the deployment of renewable energy and energy efficiency by endorsing the cooperation between Italy and Tunisia. The focus is to implement the use of sustainable energy microsystems that generate electricity from various renewable sources (solar thermal, photovoltaic…
On the effects of BAC systems and load control programs on the utility grid
2017
The electricity demand increasing for the comfort improvement in residential buildings is nowadays stressing the MV and LV networks in urban areas. In this framework, the Distribution System Operators (DSO) are exposed to the risk of reliability decrease and there is, earlier than expected, the issue of new and substantial investments for enhancing the network infrastructure. Nevertheless, DSOs have a very strong inclination to defer investment in new facilities in favour of more "flexible measures" for improving the life of the existing components. Solutions of this type are primarily based on demand management, i.e. activities aimed at encouraging the end-users to a different/smart electr…
New dispatching strategy for the integration of active-demand and distributed storage in the electricity market
2015
The proliferation of Distributed Generation (DG) in power systems calls for a redesign of electricity network management, which should be able to accommodate large amounts of intermittent generation. This issue requires a discussion about the current dispatching regulation, giving distributed storage systems and qualified electricity consumption the opportunity to provide ancillary services to the distribution grid. In this work, a new dispatching strategy for the integration of active-demand and distributed storage in the Italian electricity market is presented. The strategy is focused on a distribution Smart Grid (SG), where customers can indirectly participate to the Day-Ahead (DA) and t…
Impact of Demand Response Control Logic on Isolated Island's Distribution Networks
2019
The work presents the results of a study regarding the impact of some Demand Response control logics on an isolated distribution network. The proposed control is divided into precise steps in which the coordination between the general aggregator controller and the single local Energy Management Systems is developed and illustrated with details. The control is applied to the flexible loads and to the storage systems of photovoltaic plants installed at the end-users' houses and connected to the network. The study is carried out delivering a suitable network model of the island's system, with the implementation of load profiles for all the loads of the network for a total simulation time of 24…
Effects of Demand Side Management on the Operation of an Isolated LV Microgrids
2019
The work presents the results of a study regarding the impact of Demand Side Management actions on flexible loads distributed at the domestic end-users' facilities in an isolated low voltage microgrid. Aim of the research study is to evaluate how the implementation of local control actions on the end-user's side can impact on the operation of the isolated microgrid. The Demand Side Management is applied by each domestic user to optimize the operation of its own resources following well-defined operative steps. The study is carried out implementing a suitable model of the microgrid in Neplan environment, while the daily controlled load profiles of the end-users are evaluated using the Montec…

An Experimental Investigation of Residual Stresses in Hard Machining of AISI 52100 Steel
2011
In this paper an experimental investigation was conducted to determine the effects of the tool cutting-edge geometry, workpiece hardness, cutting speed, and microstructural changes (white and dark layers) on the residual stresses in dry orthogonal hard machining of AISI 52100 steel. X-ray diffraction technique was used to obtain in-depth residual stresses profiles in both axial and circumferential directions. The results show that tool geometry, workpiece hardness and cutting parameters significantly affect the surface residual stress, maximum compressive residual stress below the machined surface and its location. Moreover, microstructural analysis shows that thermally-induced phase transf…
