This paper presents different 2030 studies results in a pan-European framework. Specific attention is paid to the techno-economic evaluation of the application of HVDC (High Voltage Direct Current) technologies for transmission interconnecting the Italian power system with the South East Europe (SEE) Region. Focus is on the impact and on the benefits that HVDC can provide in the different cases, also...
Measuring gait quality of patients through wearable sensors has become an useful tool to assist in drug administration. Several methods, based on inertial sensors placed on lower limbs, have been proposed over the last decade to estimate clinical meaningful parameters such as gait phase distribution. Application of those algorithms for monitoring gait abnormalities would have a tremendous potential...
The present paper aims at introducing, applying and comparing two modeling approaches for including Demand Response (DR) technologies in complex pan-European power system studies. For this purpose, different outcomes of the GridTech pan-European study applying a zonal analysis are taken into account, with reference to 2020, 2030 and 2050 scenarios. Some key results of the application of the two modeling...
The present paper reports different results of a pan-European study being carried out in the frame of the European GridTech project. Specific attention is paid on the techno-economic evaluation of the application of innovative grid-impacting technologies towards RES exploitation in the future European system: three main technology categories are addressed. This paper focuses particularly on the effects...
The present paper aims at investigating the impact that Demand Response (DR) technologies may have on the future development of the pan-European power system. For this purpose, different results of the GridTech pan-European study applying a zonal analysis are presented, with reference to 2020, 2030 and 2050 scenarios. This analysis based on the modeling of the pan-European system includes the technological...
In the field of electric power transmission, HVDC (High Voltage Direct Current) is a well-established technology and presents characteristics that have made it widely attractive over HVAC (High Voltage Alternating Current) for specific applications. Currently, recent advances in the power electronics, coupled to the traditional features of HVDC, are contributing to boost the penetration of HVDC for...
We propose a framework where the human-robot interaction is modeled as a multimodal dialogue which is regulated by an attentional system that guides the robot towards the execution of structured tasks. Specifically, we propose an approach where the dialogue between the human and the robot is represented as a Partially Obervable Markov Decision Process (POMDP), while the associated dialogue policy...
The present paper proposes an empirical approach for including the effect of strategic competition in market simulation, avoiding the use of time consuming game theoretical models. The methodology is based on a linear estimation of the Lerner Index, that is a common measurement for price mark up, depending on the Residual Supply Index values of the strategic suppliers. The empirical model is estimated...
A dual EFPI/FBG pressure and temperature sensing architecture, biocompatible and with minimum cross-sensitivity, is presented. The system performs online monitoring of radiofrequency thermal ablation in liver tumor, detecting the physical phenomena; ex-vivo experiments are reported.
This study has demonstrated that the thermal conductivity of small samples of highly thermally conductive materials can be accurately measured using scanning thermal microscopy (SThM) when calibrated using Johnson noise thermometry. A nanocrystalline diamond film sample was measured in two forms, membrane and film supported on a Si substrate. The results indicate that the membrane sample is necessary...
Dynamic posturography apparatuses are important tools in the diagnosis and rehabilitation of the equilibrium control capabilities. The mechanical systems used in dynamic posturography consist in moving bases actuated by elastic elements or, more recently, by servo-motors. In this work, the accuracy of a robot for postural rehabilitation, named RotoBiT3D, controlled in impedance, was analyzed experimentally...
State-of-Charge (SoC) estimation is a key factor for correct and safe battery management, particularly for the development of the Battery Management System (BMS) [1]. The paper deals with this problem for the currently most promising technology in the battery filed: Lithium-Ion batteries. An electric model of the cell is identified and verified, in order to apply Kalman Filter Theory and design an...
All tests were carried out on a 2.66 GHz Intel Core 2 personal computer on which the Matlab computation environment and the CPLEX software had been uploaded. In the tests, the GEP problem considered is that faced by a hypothetical GENCO operating in Italy. The choice of the Italian system is only intended as a way to identify a regulatory environment concerning RES support and CO2 reduction; the generality...
The aim of this paper is to improve an optimization algorithm for coordinated management of VSC-HVDC link and DFIGs in variable frequency operation, presented by the authors in a previous work. The new features introduced in this paper concern different upper bounds on DFIG rotor and stator power flow and modified constraints on generator slips and AC offshore grid frequency. The upper bound on stator...
We present an attentional control architecture for a robotic agent capable of adapting its deliberative and executive behavior to internal and external processes. In this framework, the agent is endowed with simple attentional mechanisms regulating the sensors sampling rates and action activations. The process of changing the frequency of sensors readings is interpreted as an increase or decrease...
This paper presents a Probabilistic Load Flow (PLF) procedure that allows the impact of distributed generation (DG) on the transmission system to be assessed. By means of the Monte Carlo technique, several system states are simulated, varying the power injection of DG. The load flow solution is performed by the Newton-Raphson method and a distributed slack bus formulation is adopted, in order to distribute...
In this paper we study the performance of space-time bit-interleaved coded modulation (ST-BICM) over block-fading multi-input multi-output (MIMO) channels with iterative receivers based on minimum mean square error (MMSE) detection. We show how full diversity can be achieved with a special class of space-time precoders. Performance in terms of symbol error rate (SER) and word error rate (WER), obtained...
Energy consumption in general and interference in particular are among the most critical issues in wireless networks. In this paper we present the E-BUM calculus, a Energy-aware calculus for Broadcast, Unicast and Multicast communications in wireless ad hoc networks. We formalize the notions of sender- and receiver-centered interference and provide efficient proof techniques for verifying the absence...
The aim of this paper is to find out an optimization algorithm for wind power plants, where the wind turbines are equipped by DFIG, connected to on-shore grid by means VSC-HVDC link. The off-shore grid frequency is assumed variable under a fixed range and the wind power tracking characteristic of the DFIG has to be extended to consider the additional grid frequency dependence. The highly non linear...
The aim of the present paper is that of assessing the role of the transmission system in a liberalized electricity market, pointing out that the presence of transmission capacity limits may influence the market outcomes and above all it may make profitable a strategic behaviour rather than a competitive one by one or more producers. From this point of view, the transmission system development becomes...
