Real-time simulation test beds for new zero-emission hybrid electric vehicles are considered as an attractive challenge for future transport applications that are fully recommended in the laboratory environment. In contrast, new zero-emission hybrid electric vehicles have a more complicated charging procedure. For this reason, an efficient simulation tools development for hydrogen consumption control becomes critical. In this vein, a New Zero Emission Hybrid Electric Vehicle Simulation (NZE-HEVSim) tool for the dynamic Fuel Cell Hybrid-Electric System is proposed to smartly control multisource activities. The designed system consists of a proton-exchange membrane fuel cell used to provide the required energy demand and a Supercapacitor system for energy recovery assistance in load peak or in fast transient. To regulate the supplied power, an efficient Real-Time Embedded Intelligent Energy Management (RT-EM-IEM) is implemented and tested through various constraints. The proposed intelligent energy management system aims to act quickly against sudden circumstances related to hydrogen depletion in the basis required fuel consumption prediction using multi-agent system (MAS). The proposed MAS strategy aims to define the proper operating agent according to energy demand and supply. The obtained results prove that the designed system meets the objectives set for RT-EM-IEM by referring to an experimental velocity database.
This paper aims to study the DC-link faults and recovery scenarios based on a 12-pulse HVDC (High Voltage Direct Current) link system. DC-link to ground fault is considered as one of the most serious fault that can occur on HVDC-link. Therefore, in order to understand the system behavior in the presence of this type of fault, two DC-fault scenarios are investigated. One scenario is at the sending end of the rectifier, and the other is at the receiving end of the inverter. The faults are applied mainly to study the dynamic performance of the recovery of HVDC-link system after faults, and to validate the proposed DC fault protection function. Influence of the Voltage Dependent Current Order Limiter (VDCOL) function is also studied. The digital real-time simulator laboratory (RT-Lab) platform HYPERSIM (OP-5600) is used in modeling and simulation of the HVDC-link system by means of Software-In-the-Loop (SIL) approach. The maintenance of the system stability is investigated to ensure a high performance recovery from the fault. Ramp-up recovery method used in the DCbus voltage restoration provided by the VDCOL-function, and the validated operation of protection function against DC faults show high performance recovery from the faults. The results carried out ensure safe and desired recovery from the DC-bus faults.
