Abstract: A passivity-based power distribution control system for a hybrid electric vehicle includes a proton-exchange membrane fuel cell module, a battery module, an ultra-capacitor module, an energy management controller, and a duty cycle controller. The proton-exchange membrane fuel cell module includes a proton-exchange membrane fuel cell (PEMFC) and a PEMFC boost converter. The PEMFC module generates a PEMFC current IFC. The battery module includes a battery and a battery buck/boost converter. The battery module generates a battery current Ib. The ultra-capacitor module includes an ultra-capacitor (UC) and a UC buck/boost converter. The UC module generates a UC current IUC. The duty cycle controller controls a PEMFC duty cycle D1 of the PEMFC boost converter, a battery duty cycle D23 of the battery buck/boost converter, and a UC duty cycle D45 of the UC buck/boost converter.

Abstract: A system and a method for controlling a hybrid microgrid system (HMS) is disclosed. The HMS includes a WTG, an RSC, a GSC, a DC-link connecting the RSC and the GSC, a PV system that outputs a DC current to the DC-link, a rechargeable battery, a bidirectional BBC connected between the DC-link and the rechargeable battery, and a controller. The method for controlling the HMS includes: preparing a definition set including a characteristic element ci and equations defining desired value ci*, a fractional order sliding mode surface ζi, and a control law element uicnt; monitoring ci(t) and the HMS status; calculating the equations based on monitored information; and controlling the HMS based on the uicnt(t) calculated and in accordance with a global sliding mode control with fractional order terms. The ζi comprises a fractional time integral and fractional time derivative of ei(t), where ei(t)=ci(t)−ci*(t). The

Abstract: Control system and method for integration and transition between standalone and grid-connected operations of a hybrid renewable microgrid system include a multiple-input multiple-output controller that manages a rotor-side and a grid-side converter, structured in a back-to-back configuration, alongside a DC-DC buck-boost converter. The system harnesses energy from a solar generation unit of interconnected photovoltaic panels and a wind generation unit linked to a permanent magnet synchronous generator. Both energy sources are efficiently coordinated through maximum power point tracking control. The solar unit is directly connected to a DC bus, which also interfaces with the grid-side converter. An energy storage unit is seamlessly integrated, providing power management and voltage regulation capabilities to maintain consistent power delivery and quality, even during fluctuations in renewable energy production.
