Experimental Tests
2022
This chapter presents the outcomes of the experimental implementation of the architecture described in Chap. 4 running a hardware testbed for the emulation of domestic electrical load profiles. Besides it shows how this experimental scenario integrates both with the legacy metering architecture and with the blockchain platform. Finally, the integrated use with an Energy Management System designed on purpose is also described with the aim of ensuring intervention and automating the end user’s response to a DR event.
Multi-objective Optimization of Energy Hubs at the Crossroad of Three Energy Distribution Networks
2016
This paper provides a multi-objective optimization framework aimed at the management of a multi-carrier energy system involving both electricity and hydrogen. Using the concept of the multi-carrier hub, the proposed system has been modelled in order to define completely every energy flow inside the plant. After that, a heuristic multi-objective optimization algorithm, the Non-dominated Sorting Genetic Algorithm II, has been implemented for the energy management of the plant, taking into account simultaneously three different objective functions related to economic and technical goals. This optimization process provides the set point defining the working configuration of the plant for a dayl…

An integrated platform for electrical modeling of microgrids
2012
Aggregates of loads and generators working coordinated, called microgrids, are new entities appearing at distribution level. In this paper, an integrated platform for energy modeling of microgrids is proposed. The platform allows the evaluation of heat and electrical energy balance terms and of the steady state features of the distribution system supplying the grid. The interface is friendly and allows the positioning of different items, such as co-generators, photovoltaic and wind units, Electric Vehicles parking lots and buildings. The platform is built in Matlab while the interface in Java. Each component of the model can be placed using a CAD facility and each ‘node’ is characterized by…
Optimal energy management in the smart grid
2017
In this chapter, the problem of energy management in smart grids is outlined. Optimized energy management is considered here as the operation of energy and power flow control in the aim of attaining minimum cost or minimum power losses while meeting technical constraints. Of course, according to the type of energy system in which such operation is carried out, the meaningful variables and objectives in the problem may largely change. As the extension of the system increases, the influence of the physical behaviour of the electrical power lines takes a more important role. Power electronics takes instead an increasing influence, as the dimension of the power system decreases although Kirchho…
Energy Management System in Grid-Connected Small Scale AC/DC Microgrids Including Renewable Sources and Flexible Loads
2022
The growth of small scale microgrids with diverse distributed generations has drawn attention to their effective energy management. In this paper, for various energy scenarios, an energy management system is adopted to minimize the energy purchased by a hybrid AC/DC microgrid from the upstream grid due to high peak-hour energy prices and maximise generation from renewable sources, while adjusting the most optimal charge/discharge control strategies for flexible loads such as electric vehicles and storage systems, and the supply of non-controllable loads. In addition, peak shaving is simultaneously implemented in this proposed model without considering minimum power deviation as an objective…
Intelligent Management Systems for Energy Efficiency in Buildings: A Survey
2014
In recent years, reduction of energy consumption in buildings has increasingly gained interest among researchers mainly due to practical reasons, such as economic advantages and long-term environmental sustainability. Many solutions have been proposed in the literature to address this important issue from complementary perspectives, which are often hard to capture in a comprehensive manner. This survey article aims at providing a structured and unifying treatment of the existing literature on intelligent energy management systems in buildings, with a distinct focus on available architectures and methodology supporting a vision transcending the well-established smart home vision, in favor o…
Social-Behavioral Aware Optimization of Energy Consumption in Smart Homes
2018
Residential energy consumption is skyrocketing, as residential customers in the U.S. alone used 1.4 trillion kilowatt-hours in 2014 and the consumption is expected to increase in the next years. Previous efforts to limit such consumption have included demand response and smart residential environments. However, recent research has shown that such approaches can actually increase the overall energy consumption due to the numerous complex human psychological processes that take place when interacting with electrical appliances. In this paper we propose a social-behavioral aware framework for energy management in smart residential environments. We envision a smart home where appliances are int…
REPUTATION MANAGEMENT ALGORITHMS IN DISTRIBUTED APPLICATIONS
2020
Nowadays, several distributed systems and applications rely on interactions between unknown agents that cooperate in order to exchange resources and services. The distributed nature of these systems, and the consequent lack of a single centralized point of control, let agents to adopt selfish and malicious behaviors in order to maximize their own utility. To address such issue, many applications rely on Reputation Management Systems (RMSs) to estimate the future behavior of unknown agents before establishing actual interactions. The relevance of these systems is even greater if the malicious or selfish behavior exhibited by a few agents may reduce the utility perceived by cooperative agents…
Designing an Energy Management System for smart houses
2015
Most advantages that the smart grid will bring derive from its capability of improving reliability performance and customers' responsiveness and encouraging greater efficiency decisions by the customers. In this optic, the paper presents an innovative Energy Management System for smart houses, allowing the optimization of the electricity cost and electrical energy consumption and, at the same time, preserving the end-user comfort.
