La ricerca ha analizzato la legislazione elettorale e quella sui partiti politici in Russia nella loro evoluzione. Attraverso un puntuale esame delle leggi nelle loro specificità si proveranno a identificare gli obiettivi primari del legislatore fino ad analizzare gli effetti sui partiti politici e, in particolare, su quelli di opposizione. Per...

This paper addresses the issue of the application of PhotoVoltaic (PV) Distributed Generation (DG) units for supplying reactive power to the grid. In order to reach this aim, an advanced control scheme to suitably drive the injection of both active and reactive power into a MV radial distribution grid has been developed. Such algorithm allows a...

The widespread of smart microgrids has been also determined by the development of more and more efficient cogeneration and trigeneration power plants fed by fossil fuels or renewable sources. In the residential and the tertiary sectors, many projects are focused on the installation of low size microturbines, engines, chillers and heat pumps to...

Microturbines represent a suitable technology to be adopted in smart microgrids since they are characterized by affordable capital and maintenance costs, high reliability and flexibility, and low environmental impact; moreover, they can be fed by fossil fuels or biofuels. They can operate in cogeneration and trigeneration mode, thus permitting...

This paper faces the problem of the protection against overvoltages of atmospheric origin for modern electric mass-transit systems such as light-rail transportation systems (LRTS) and proposes a transmission-line (TL) model for the field-to-line coupling, which allows to evaluate the response of the supply system of a typical LRTS to a generic...

The problem of the high-frequency electromagnetic field coupling to an overhead electrical transmission line is an important issue in power signal transmission and here it is dealt with the regularization theory of ill-posed problems. The integro-differential equation describing the field-induced current into a line of finite length lying over...

A method for the evaluation of the capacitance matrix of a system of finite-length onductors is given. It is shown that the problem can be reduced to the solution of a convolution type integrodifferential equation system and an effective and accurate procedure to cope with this is described. The procedure first appfies the convolution theorem...

The general theory describing the electromagnetic field radiated by a lightning stroke over a conducting ground is presented in this paper. The derivation of the Green functions necessary to solve the problem is discussed in detail, and the determination of the expressions for the electromagnetic field components is carried out in a form that...

In this paper, we present a new formulation for the evaluation of the electromagnetic field levels in the near zone of a cellular radio base-station collinear array antenna. The algorithm allows to determine the real current distribution along each half-wave dipole forming the array for a given exciting function and it enables to take into...

A general method for the solution of dual integral-equation systems is discussed in the context of applications in engineering electromagnetics. The approach follows a formulation based on a Fourier-series expansion of the unknown function and a successive expansion in a Neumann series of the Fourier-series coefficients. It is characterized by...
