Special Issue Information

Dear Colleagues,

The 22nd IEEE International Conference on Environment and Electrical Engineering (IEEE EEEIC22) is an international forum for the exchange of ideas and information on energy systems. The conference provides a unique opportunity for designers and people from industry to interact with manufacturers, energy utilities experts, and university researchers and to discuss a wide variety of topics related to energy systems and environmental issues. The ever-increasing awareness of environmental concerns and intensive international efforts to reduce emissions of greenhouse gases and to foster a sustainable energy transition has stimulated the best contributions toward achieving the goals of renewable energy diversification, and sustainable development. IEEE EEEIC 2022 is the 22nd edition of the conference, which is one of Europe’s largest, longest-running professional networking and educational events. The conference has been co-sponsored by IEEE since 2008 and by EMCS, IAS, and PES since 2015.

Prof. Dr. Rodolfo Araneo

In industrial settings, mechanical systems for clamping workpieces onto machine tools or for lifting and handling ferrous material are often replaced by magnetic clamping systems. For large lifting applications, the most suitable magnetic clamping systems are electromagnetic (EM) and electro-permanent (EP) approaches. Their configurations, direct and induced poles or direct poles only, need to be discussed in order to choose the most appropriate and economical setup for the specific application. In addition, an evaluation of the difference in the energy efficiency between EM and EP systems, which is often not simple, is presented. To achieve this, a hybrid control system for EM or EP systems was developed and, with the help of this prototype, an analysis of these two magnetic systems was carried out to highlight the main differences. The hybrid control system consists of a single control unit that can be used by both systems, and can be achieved by simply changing the type of lifting magnet. In this research, the realization, operational description, and analysis performed on this prototype were addressed. Full article

Parameter estimation represents an important aspect of modeling electromagnetic systems, and a wide range of parameter estimation strategies has been explored in literature. Most parameter estimation methodologies make use of either time-domain or frequency-domain responses as measured from the terminals of the device under test. Very limited research has, however, been conducted into exploring the use of modal decomposition strategies on the time-domain waveforms for parameter estimation applications. In this paper, the use of Empirical Mode Decomposition for estimating the parameters of a three-section lumped parameter transformer model is explored. A novel approach is proposed to define the optimization cost function in terms of the intrinsic modes of simulated time-domain waveforms. The results are compared with results obtained using classical time-domain and frequency-domain approaches. It is shown through an impulse response test that weighting the modes obtained from the Inferred Empirical Mode Decomposition approach presented in this work offers advantages in terms of accurately representing the target model transfer function dynamics and can assist in interpreting the various dynamic modes associated with the target model.

The Italian National Recovery and Resilience Plan (NRRP) includes, among other measures, investments in hydrogen vehicle refuelling stations, intending to promote the use of fuel cell electric vehicles (FCEVs) for long-haul freight transport. This paper evaluates the impact that this action could have on CO2 emissions and fuel consumption, focusing on a case study of the Campania region. The proposed approach, which can also be transferred to other geographical contexts, requires the implementation of a freight road transport simulation model; this model is based on the construction of a supply model, the estimation of road freight demand, and an assignment procedure for computing traffic flows. This study covers the period from 2025 to 2040, according to the forecasts of the NRRP and some assumptions on the action effects; moreover, it is assumed that hydrogen is entirely produced from renewable sources (green hydrogen). The key findings from three different scenarios show that savings between 423,832 and 778,538 tonnes of CO2, and between 144 and 264 million litres of diesel could be obtained. Full article
