The BAC factor method: Application to a real Italian not-residential building
2016
The paper focuses the evaluation of the impact of Building Automation Control (BAC) systems on not-residential buildings. In particular, this work shows how the control, monitoring and automation actions considered by the European Standard EN 15232 can influence the electric and thermal energy consumptions of the University of Palermo DEIM (Department of Energy, Information Engineering and Mathematical Models) building. After evaluating the building energy consumptions, by using the CEI Guide 205-18, the BAC systems are chosen and sized and an economic evaluation of their installation cost is also carried out.
Linkages between the Elements of Management Control Systems in a Non-Profit Organization
2011
This qualitative case study examines the emergence of MCS package. We apply the MCS package framework of [Malmi, T. and Brown, D.A. (2008) Management control systems as a package-Opportunities, challenges and research directions, Management Accounting Research, Vol. 19, Iss. 4, pp. 287-300] and investigate the linkages between different control elements of MCS package. The control elements of MCS package, particularly governance structures and cybernetic systems became often overlapping and redundant. All the control elements remained in the MCS package when they were once constructed. Even tough a large number of cybernetic controls (i.e. balanced scorecard, budgets, quality management sys…
User Activity Recognition for Energy Saving in Smart Homes
2015
Abstract Energy demand in typical home environments accounts for a significant fraction of the overall consumption in industrialized countries. In such context, the heterogeneity of the involved devices, and the non negligible influence of the human factor make the optimization of energy use a challenging task; effective automated approaches must take into account basic information about users, such as the prediction of their course of actions. Our proposal consists in learning customized structural models for common user activities for predicting the trend of energy consumption; the approach aims to lower energy demand in the proximity of predicted peak loads so as to keep the overall cons…
Augmented Reality Applied in Machining Processes and Cutting Tools Management
2014
This paper describes the benefit obtained from implementing a cutting tool management system. Also, a state of the art on tool management systems available on the market is presented. By analysing the drawbacks generated by the implementation of such a system, we are providing a cheap and practical solution: an Augmented Reality aided machining and tool management system. Using augmented reality we managed to improve the tool management systems by providing, at the scene of action, all the necessary tool information in a much more user friendly way.
Optimizing droop coefficients for minimum cost operation of islanded micro-grids
2017
This paper shows how minimum cost energy management can be carried out for islanded micro-grids considering an expanded state that also includes the system's frequency. Each of the configurations outputted by the energy management system at each hour are indeed technically sound and coherent from the point of view of generation-consumption balancing by exploiting a frequency dependent load flow algorithm. A Glow-worm Swarm Optimization (GSO) algorithm carried out in a 24 hour time frame provides optimized results. A test has been carried out for a residential PV-Storage-Microturbine islanded micro-grid to show the feasibility as well as the efficiency of the proposed approach and results ar…
Smart district energy optimization of flexible energy units for the integration of local energy storage
2017
Several changes are involving electrical power systems, especially distribution networks. For this reason, the actors in charge of managing and operating reliably these grids are facing many technical issues regarding demand and supply balancing, Renewable Energy Sources and Electric Vehicles integration, peak load shaving, etc. In this context, many energy actions have been implemented for providing services to the power system managers by means of prosumers' demand and/or supply flexibility. This study reports the development of a centralized energy management solution for smart grids equipped with local storage devices, RES, consumers and other energy facilities in a district context. Th…
Microgrid supervisory controllers and energy management systems:A literature review
2016
Abstract Microgrids (MGs), featured by distributed energy resources, consumption and storage, are designed to significantly enhance the self-sustainability of future electric distribution grids. In order to adapt to this new and revolutionary paradigm, it is necessary to control MGs in intelligent and coordinated fashion. To this aim, a new generation of advanced Microgrid Supervisory Controllers (MGSC) and Energy Management Systems (EMS) has emerged. The aim of this paper is to summarize the control objectives and development methodologies in the recently proposed MGSC/EMS. At first, a classification of control objectives is made according to the definition of hierarchical control layers i…
Facilitating Teaching and Learning Capabilities in Social Learning Management Systems: Challenges, Issues, and Implications for Design
2013
The adoption of learning management systems LMSs and social networking technologies SNTs in higher education has begun to change the way learning and teaching take place. However, the adoption of these emerging tools as a means to support collaboration seems to be slow. This study seeks to identify issues and opportunities related to LMS and SNT utilization and combination to enhance learning and teaching capabilities in higher education. An illustrative study reports on student and instructor experiences of using these systems in two Norwegian universities. The empirical evidence gained is analysed in terms of current benefits and drawbacks, and future challenges and capabilities. This pro…
Applicational Aspects of a New Diagnostic Methodology for Fault Location in MV Networks: Problems, Solutions and Improvements
2005
The electrical energy market liberalization has encouraged utilities to make new investments at distribution level so as to attain higher quality levels. Service continuity is one of the aspects of greater importance in the definition of the quality of the electrical energy, for this reason, the research in the field of faults diagnostic for distribution systems is spreading ever more. The Authors have just developed a new methodology for diagnostic management of automated distribution systems. The technique is based on the use of circuital models of the electrical system resulting from the composition of quadripoles. In this paper, after a brief description of the proposed approach, the is…
A multi-agent system for managing adverse weather situations on the road network
2010
The development of traffic management and control strategies to improve traffic flows and road safety is necessary due to the high dynamism of traffic flows. The use of distributed intelligent systems can help the traffic organizations and the road operators to cope with possible incidents on the road network, especially when the incidents are related to adverse meteorological conditions. In that case, the probability of road accidents is increased due to the difficulty of driving under bad weather conditions. So, if the operators detect any meteorological incident, they must decide how to deal with it in order to improve traffic safety. In this paper we introduce a new multiagent system (M…
