Innovative algorithms for the management of combined RES-BESS systems

2017

The issue of the optimal management of the available energy resources also at end-user level is getting more and more attention. The paper deals with the definition of innovative algorithms for managing electrical storage systems in hybrid photovoltaic and wind plants, also taking into account different pricing periods and a grid emergency condition in which the Utility can request an injection of power by the end-user. Application examples for explaining the operation of the algorithms are presented.

Surgical conversion with graft salvage as a definitive treatment for persistent type II endoleak causing sacenlargement

2015

Objective The goal of this study was to present open surgical conversion with graft salvage or "semiconversion" as a definitive and safe treatment for untreatable and persistent type II endoleaks causing sac enlargement after endovascular aneurysm repair. Methods Between January 2001 and December 2014, 25 of 1623 endovascular aortic repair (EVAR) patients were selected as candidates for open semiconversion. The indication was persistent type II endoleak in 13 patients (12 of whom received previous attempts of embolization), type I and II endoleak in 2 patients, and sac growth without imaging evidence of endoleak in the other 10. After the infrarenal aorta was prepared (via a retroperitoneal…
