research interests are in the areas of singular perturbation and large scale systems. Abstract-This paper deals with the problem of the estimation of regions of asymptotic stability for continnons, antonomom, nonlinear systems. The first part of the work provides a comprehensive survey of the existing methods and of their applications in engineering fields.(More)
This paper presents the operational planning of an integrated trigenerative system.The installation of a CHCP plant depends on the financial investments. This work shows an optimization procedure to foresee a management of the system aimed to increase yield of investment. The optimization procedure seems to work well as foreseen PBP is short if compared(More)
The ecodesign of modern residential and commercial low-voltage systems implements energy and equipment cost savings, optimizing the size of the distribution system without compromising its functionality or causing environmental contamination, including electromagnetic pollution. Protection of persons against shock hazards should be increased, and the(More)
The analytical study of grounding systems is only possible for basic electrodes, i.e., hemispherical and spherical electrodes, rods, and horizontal wires. However, it is normal practice to employ more complex earthing systems, such as grounding grids integrated with rods, in order to obtain lower resistances to ground and improve the electrical safety of(More)
One of the main purposes of grounding systems is to safely inject fault currents into the soil; such currents flow through any buried conductive objects (e.g., other earth electrodes) eventually present along their path to the source. As a result, even though grounding systems may be metallically isolated, they become coupled due to the flow of the(More)
This paper presents the problem of power penetration of photovoltaic (PV) systems in urban networks. After a qualitative problem description, two different environments for PV systems have been analyzed: rural and urban networks. Concerning the rural network, a single line has been simulated in order to evaluate the relation between the number of PV systems(More)
The worldwide global market requires electrical engineers to have a deep understanding of the bonding and earthing practices adopted in different countries around the world. This knowledge is essential to obtain effective designs and high safety standards and can promote the elimination of technical obstacles that can still create market barriers. The full(More)
The bonding of electrical equipment plays a crucial role in maintaining the same potential between conductive parts likely to be energized and conductive parts liable to introduce a “zero” potential into the premises. Voltage rises between such parts are unsafe, as they may induce harmful currents through the human body, the magnitude of which(More)
The aim of this work is the evaluation of different analytical methods devoted to the study of shielding of extremely low frequency (ELF) magnetic fields with conducting and ferromagnetic materials. In this paper an extensive analysis of some approaches are presented and compared to a numerical method based on a hybrid FEM/BEM formulation. The study wants(More)
In low-voltage systems, ground faults do not necessarily involve the actual earth, but fault currents may return to the source via conductors. Such conductors, which provide a clear path toward the source, are defined in the applicable codes and technical standards as equipment grounding conductors or protective conductors.
