Le fonti rinnovabili in Sicilia: impatti sul mercato zonale e sulla gestione del sistema elettrico
L’articolo descrive gli aspetti tecnici e di mercato del sistema elettrico siciliano mettendo in evidenza le cause che hanno portato all’aumento del prezzo zonale nelle ore serali, gli effetti che le FRNP hanno sui mercati elettrici (MGP e MSD) e sulla gestione del sistema elettrico siciliano.
Methodologies to uprate an overhead line. Italian TSO case study
The amount of wind power and other time-variable non-dispatchable electricity generation is rapidly increasing across the world, causing a significant change in the electrical system configuration. The existing structural asset isn't adequate to dispatch these new power that have a priority in the energy dispatching. In addiction the outage of substations on the grid and the increase of consumptions have caused growing load currents. In order to satisfy these needs, TSOs have adopted new measures on existing power lines and N-1 criteria to ensures the electrical grid security. These particular devices are Dynamic Thermal Rating (DTR) systems. After introducing thermal resistant conductors a…
Uprating an overhead line. Italian TSO applications to increase system N-1 security
This paper analyzes innovative devices to optimize the energy flows transmission on existing overhead lines. Indeed sometimes the structural asset isn’t adequate to manage energy generated by Renewable Energy Source (RES) in particular operating conditions. In addiction the outage of primary substations on the grid and the increase of consumptions have caused growing load currents. In order to satisfy these needs, TSOs have adopted new measures on existing power lines and N-1 criteria to ensures the electrical grid security. These particular devices are Dynamic Rating systems. After introducing thermal resistant conductors and Dynamic Rating (DR) solutions, paper reports two different appli…
