In this paper, an off-grid hybrid energy system consisting of micro run-of-river hydro power plant, photovoltaic system, wind turbines, diesel generator as a back-up source, batteries and converters is studied. The objective research to obtain the cost effective configuration which will meet consumption demands, respecting total net present costs. HOMER software used simulate determine most app...

Based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. However, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. To resolve this problem, hybridization of the fuel cell and energy storage device...

in this paper, an intelligent control strategy based on combination of the “flatness based control technique” and the “perturbation and observation (p&o;) mppt algorithm” is developed and investigated to control a hybrid electric energy source (heps). this ehps is composed of a fuel cell system (fc) and a solar panel (sp), as the main source and a supercapacitor bank (sc), as the auxiliary sour...

in most cases, fiber reinforced self-compacting concrete (frscc) contains only one type of fiber. the use of two or more types of fibers in a suitable combination may potentially not only improve the overal properties of self-compacting concrete, but may also result in performance synergie. the combining of fibers, often called hybridization, is investigated in this paper for a cimentetious mat...

Complex power generation scheduling, correlated uncertainties, environmental issues and hybrid energy system modeling have become very important research topics due to rapid growth of large-scale distributed renewable energy system, deregulated electric power markets and responsive demand. The intermittent nature of the primal energy sources (i.e. wind, sun, water) increases uncertainty as well...

This paper presents a design of a hybrid energy system with renewable resources. Hybrid system can better cover the energy demands of small energy objects in comparison with the classic photovoltaic (PV) or wind energy system. Combination of different sources in cooperation with energy accumulation requires sophisticated control system. The paper describes the intended design of the hybrid syst...
