Currently, major technical challenges linked to the implementation strategy of smart grids are associated with new studies and researches on the impact of renewables energy sources on the parameters of power transmission and distribution networks. Current dedicated softwares permit the modeling and simulation of power distribution structure which includes different types of renewable energy sources...
This paper evaluates a system with variable-speed wind power and photovoltaic generation connected to the power grid through a full-scale Synchronverter. It analyses the effects of dynamically controlled virtual inertia as a means of increasing performance. The full-scale power converter is composed of a back-to-back three-phase power converter. The controller of the converter connected to the wind...
DC microgrid is an effective solution to integrate renewable energy sources with conventional utility grid, especially for photovoltaic generation. A DC microgrid configuration based on modular photovoltaic generation system and energy storage devices, which features good redundancy and high efficiency, is investigated in this paper. In order to optimize energy utilization, a power management scheme...
MetaPV is the first project world-wide that will demonstrate the provision of electrical benefits from photovoltaics (PV) on a large scale, showing the way toward cities powered by renewable energy sources. Additional benefits for active grid support from PV will be demonstrated at two sites: a residential/urban area of 128 households with 4 kWp each, and an industrial zone of 31 PV systems with 200...
This paper presents the structure and capabilities of a small, grid-interactive distributed energy resource system comprised of a photovoltaic source, plug-in hybrid electric vehicle, and various local loads. Implemented at the residential level, this system, with a plug-in hybrid electrical vehicle, has the ability to isolate a house from the utility grid (intentionally due to a fault or other abnormal...
Renewable energy sources based on photovoltaic along with battery-based energy storage necessitate power conditioning to meet load requirements and/or be connected to the electrical grid. The power conditioning is achieved via a DC-DC converter and a DC-AC inverter stages to produce the desired AC source. This is also the case even when the load is of DC type such as the typical electronic devices...
