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…
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…
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…
CHANGES OCCURRED IN A PORCELAIN FACTORY DUE TO QUALITY MANAGEMENT SYSTEM IMPLEMENTATION
2019
The issues approach in this research show the benefits of the implementation of ISO 9001 standard in different companies as well as the importance of certain criteria with respect to customer satisfaction and confidence. This standard specifies requirements for a quality management system and it is based on a number of quality management principles including a strong customer focus, the motivation and implication of top management, the process approach and continual improvement. The criteria taken into account help to improve the quality management system of the organization. The purpose of this paper is to identify the changes due to the implementation of a quality management system based …
The Effectiveness of Compliance Management Systems – An Experimental Approach
2014
Abstract This paper presents the results of an experimental approach to further strengthen activity in the area of Compliance Management Systems (CMS). It highlights the use of CMS in order to conduct business through persons which are ethically sensitized. Possible cause-effect relations are tested and evaluated. The paper highlights that not all applied measures do have a positive impact on decisions which have to be taken in ethical dilemma situations. The effectiveness of CMS depends on a careful selection of the right activities. Nevertheless elements could be identified which are likely to have a stronger impact on the decision making than others. These should be in the focus when des…
A fuel cell-battery hybrid power supply for portable applications
2010
Today, academic and industrial research is addressed to fuel cell based hybrid power supply in many fields of applications including stationary, automotive and portable electronics. Increasing source runtime, speeding up the transient response while minimizing weight, volume and cost of the power supply system are key requirements of all applications. According to the particular application, the power management system is optimized for a specific feature. In this paper, a fuel cell–battery hybrid power supply for a Digital Camera is proposed, although the control algorithm can be efficiently applied to any portable device. Thanks to an innovative control on the input power, any fuel cell pr…
