Optimization of energy production systems is a relevant issue that must be considered in order to follow the fossil fuels consumption reduction policies and CO2 emission regulation. Increasing electricity production from renewable resources (e.g., photovoltaic systems and wind farms) is desirable but its unpredictability is a cause of problems for the main grid stability. A system with multiple...

This paper presents modeling and control of a hybrid distributed energy sources including photovoltaic (PV), fuel cell (FC) and battery energy storage (BES) in a microgrid which provides both real and reactive power to support an unbalanced utility grid. The overall configuration of the microgrid including dynamic models for the PV, FC, BES and its power electronic interfacing are briefly descr...

This paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. The hybrid DC power sources are connected to grid using power electronic converters include DC-DC converter and grid connected voltage source inverter. The power from hybrid power sources is controlled during voltage sag by designing of control strategy for DC-DC converter....

A novel converter topology interfacing hybrid distributed energy sources and dc bus is proposed in this paper for integration of renewable energy sources with residential micro grid. This converter has low number of active device compared to the converters usually applied to similar application. Multi-Winding transformer is employed for achieving Low input and output current ripple, high voltag...

This article focuses the application of Levy flight based PSO algorithm for the solution of micro grid power dispatch problems. The proposed algorithm is tested on micro grid dispatch problem consisting of wind, diesel and fuel cell plants. The effectiveness of the algorithm has been verified on a test system having distributed generation compared with the other existing techniques, considering...

The tensile properties of multiscale, hybrid, thermoplastic-based nanocomposites reinforced with nano-CaCO3 particles and micro–short glass fibers (SGF) were predicted by a two-step, three-dimensionalmodel using ANSYS finite element (FE) software. Cylindrical and cuboid representative volume elements were generated to obtain the effective behavior of the multiscale hybrid composites. In the fir...
