MANAGEMENT STRATEGY OF HYBRID WIND/ SOLAR SYSTEM

In this paper, the design and model of the hybrid wind /photovoltaic system using Matlab/Simulink environment is studied. The objective of this work is the study of a hybrid central power, which combines two renewable energy sources (wind, solar) with storage and an emergency generator. The management of different energy sources is ensured by a manager who controls the opening and closing switches, depending on weather conditions (illumination, wind speed).To be assured the good performance of this system, we have proposed an energetics flow management algorithm that takes into consideration the meteorological conditions (wind and the solar irradiation).When the wind/PV hybrid system generated power from is not sufficient to supply the load demand, the diesel generator turns on to supply the power shortage and the ultra-capacitor (UC) bank serves as a short duration power source to meet the excess power that cannot be satisfied by the diesel generator because of their response time. We examined the dynamic performance of the hybrid system and its potentiality in autonomous operation by simulation results

A case of electromagnetic interference between HeartMate 3 LVAD and implantable cardioverter defibrillator

Implantable cardioverter defibrillators (ICDs) have been shown to have a significant benefit in reducing sudden cardiac death (SCD) in patients with systolic heart failure. Additionally, cardiac devices as a bridge to transplant or destination therapy are often used in patients with end-stage systolic heart failure. As a result, most patients with left ventricular assist devices (LVADs) also have an ICD. Here, we present an electromagnetic interference (EMI) between HeartMate 3 LVAD and ICD. This issue might be critical for both electrophysiologists and advanced heart failure cardiologists to understand prior to implantation of ICD/LVADs in these patients
