The work developed and proposed in this paper deals with innovative control schemes applied to synchronous generators. In particular, the FeedBack Linearization (FBL) technique and the Sliding Mode (SM) method have been applied to regulate voltage and electric power. To do this, the basic equations of the generator have been re-formulated into...

The strong increase in the number of installed photovoltaic (PV) production plants has slowly changed the assets and the operating conditions of the electricity power system. In this context, the supply and control of the reactive power from the renewable generation plants are becoming an important issue to be exploited that can facilitate the...

Background: During eye rotations the vitreous humour moves with respect to the eye globe. This relative motion has been suggested to possibly have an important role in inducing degradation of the gel structure, which might lead to vitreous liquefaction and/or posterior vitreous detachment. Aim of the present work is to study the characteristics...

In this paper, we develop a mathematical model of blood circulation in the liver lobule. We aim to find the pressure and flux distributions within a liver lobule. We also investigate the effects of changes in pressure that occur following a resection of part of the liver, which often leads to high pressure in the portal vein. The liver can be...

Intravitreal drug delivery is a commonly used treatment for several retinal diseases. The objective of this research is to characterize and quantify the role of the vitreous humor motion, induced by saccadic movements, on drug transport processes in the vitreous chamber. A Perspex model of the human vitreous chamber was created, and filled with...

One of the main challenges in future power systems is the enormous integration of generation units using high power converters as interface, it decouples new power sources from the AC power grid, incapacitating a natural frequency response. This situation decreases the total system inertia affecting the ability of power system to overcome...

The aim of the present article is to propose an innovative simplified approach for the evaluation of active and reactive power losses for large photovoltaic plants. This methodology can be then employed in the design phase of large photovoltaic plants in order to have a preliminary evaluation of the system efficiency and of the capability of...

Abstract This paper proposes a methodology for the equivalent modeling of large photovoltaic power plants at the Point of Interconnection with the transmission/distribution network. The interest in such a methodology lays in the fact that recently Transmission/Distribution System Operators (TSOs/DSOs) have extended the requirements for the...

This paper proposes an advanced nonlinear control algorithm to manage active power and voltage provided by a synchronous generator. The algorithm is based on the so-called FeedBack Linearization (FBL) theory, which relies on the central concept to algebraically transform nonlinear systems dynamics into fully or partly linear ones, so that...
