The change in the electrical nature of the loads together with the loss of linearity are increasingly common phenomena in buildings, which requires special attention during the design phase of the electrical system in order to avoid problems in the management of reactive power flows and to better manage the power quality of the system. The presence...

Commercial Battery Energy Storage Systems are equipped with a standard control unit with simplified logic, able to reduce the impact of the power system on the electric grid. The standard control is locked in a closed environment without any chance to modify the logic. The control unit receives signals from current sensors located at the entrance p...

In the present paper an innovative street lighting system with solar PV and battery as the source of electricity was monitored and analyzed considering a case study installed in Italy center. A Light Emitting Diode (LED) is used together with a dimmer control system. This application is new because high efficiency PV cells are applied to the cylind...

Public lighting system represents a key role in the energy transition process, considering the high electricity consumptions related to this sector. The integration of renewables could be suitable for this application and many solutions of solar-based lamps for street lighting are spreading. In this research work, a specific application of a PV-int...

This study examines the electrical performance and management of hybrid solar street lighting systems with the objective of optimizing their operation for sustainable urban development. Hybrid solar streetlights, which integrate photovoltaic panels with additional power sources, offer resilience and reliability that are crucial for urban settings....

In order to put into practice the objectives proposed by the policy of energy transition towards systems and buildings increasingly electrified, smart and sustainable, the massive digitization of environments and systems in both residential and commercial plays a key role, in view of the 'internet of things'. This paper aims to demonstrate the poss...

In recent years the development of LVDC distribution networks is under consideration. DC electrical distributions offer several advantages compared to AC ones in many applications, in particular in the presence of energy storage systems and distributed generation like high efficacy, flexibility and simple integration of renewables. The DC distribut...

Under the pressure of the ecological transition, electricity is more and more crucial for the sustainable economic and social development of cities. Energy flows are increasing in city distribution networks, and Distribution Systems Operators (DSOs) are constantly looking for new solutions to meet customer demands. Local flexibility services based...

We know that the energy transition refers to the current electrification of consumption and the parallel decarbonization of the electricity that powers it. The transition model is called also of the 3D: decarbonization, digitalization and decentralization. An important role is played from the digitalization and smartization of the grids that permit...

At the energy consumption level, buildings are currently the largest sector, therefore, the energy efficiency of these structures, assumes a priority role in refurbishing projects. The “building automation” as well as the redesign of the electrical and thermal system of a structure can offer significant contributions in terms of energy saving, comf...

In recent years, a new design methodology is finding fertile ground in the building and plant engineering field: building information modeling (BIM). BIM is an innovative modeling method that proposes a substantial change in the entire workflow of a project aimed at the digitization of information processes and is supported by the transition from 2...

Fifteen years after the connection of the first PV plant to the distribution network of the city of Milan, the role of this technology is more and more crucial, considering the Italian and European energy transition goals. The availability of a zero-emission modular and dispersed electricity generation could allow the cities to meet the growing ele...

The paper presents a performance assessment of load profiles clustering methods using silhouette value criterion, a method of interpretation and validation of consistency within clusters of data. Three of the most common clustering methods are considered: Density-Based Spatial Clustering of Applications with Noise, Hierarchical cluster analysis, k-...

This paper presents the final achievements of an Education project granted by the Erasmus+ Programme of the European Commission (EC), focused in particular on three fields that are considered enablers for Smart Cities (SCs): Telecommunications and Computer Networks, IT Security, and Smart Grids (SGs). Policy makers and stakeholders in Palestine (PS...

The pandemic generated by Covid-19 caused social and economic consequences that constituted a global challenge for all countries. Italy was one of the first nations to be affected by the pandemic, especially in the heart of its production system and in the most densely populated area: the Lombardy Region. Starting in February 2020, there was a prog...

In this study, a novel trigeneration system is conceived to produce heat and electricity and to provide cooling for the health treatments and touristic facilities of a spa, based on the natural hot water and solar sources. The power generation components, individually considered, are commercially available ones, but their novel combination and the...

Nowadays, Distributed System Operators (DSOs) are facing more and more difficult challenges in meeting the user needs with an increasing overall power demand, at the same time guaranteeing the required level of reliability. A possible solutions is offered by the Demand Response (DR) management, aiming to reduce the total load demand of the distribu...

The paper presents the mid-term progress report of a project granted by the Erasmus+ Programme, focused in particular on three fields that are considered enablers for Smart Cities (SCs): Telecommunications and Computer Networks, IT Security, and Smart Grids (SGs). Policy makers and stakeholders in Palestine (PS) have made the decision to move towar...

A theoretical and experimental analysis of a thermal-photovoltaic panel, whose purpose is to produce both electrical and thermal energy, has been performed. In order to achieve the main objective, the different components that constitute the thermal-photovoltaic panel have been studied and a simulation model of the thermal-photovoltaic panel has be...

The main objective of this paper is to perform a theoretical and experimental analysis of a thermal-photovoltaic panel whose purpose is to produce both electrical and thermal energy and to analyze under which conditions it is better to use a single hybrid system than two separate systems (PV only and thermal collector only). In order to achieve the...
