Improved backtracking search optimization algorithm for PV/Wind/FC system

Abstract

This paper uses a novel optimization method based on the improved backtracking search optimization algorithm (IBSA). The study is conducted for a hybrid stand-alone system composed of photovoltaic panel (PV), wind turbine generator and fuel cell electrolyzer (FC). To demonstrate the effectiveness of the IBSA, four benchmark functions are used. The result shows the better exploration and exploitation of the improved backtracking search optimization algorithm in terms of convergence and speed for system comprinsing PV panel wind, turbine generator and fuel cell. The proposed algorithm is used to optimize the annual total cost (ATC) of the energy produced and feed up the load demand. The economic evaluation of the Hybrid PV/Wind/FC system is done throughout hourly demand and daily wind speed and insulation. The simulation results justify the robustness of the IBSA.

Impact of field roughness and power losses, turbulence intensity on electricity production for an onshore wind farm

“…Changing of wind speed by altitude in study terrain, Kitka Onshore wind farms: Wind turbines sitting over complex terrains, Atmospheric stability is rarely close to near neutral (highly convectiveunstable during the day time and highly stable nocturnal conditions with high shear at night time), much higher ambient turbulence level [18,19]. The surface flow characteristics are highly dependent on the slope of the hill [20,21].…”

An automatic multi-axis solar tracking system in Ramadi city: design and implementation

“…However, from previous studies we conclude that there are many challenges affecting the production of solar energy, which must take into account in building the system of tracking the path of the sun: Solar light sensor, energy consumption to run the tracking engine, determination of the first location of the solar panel, reflection of scattered radiation from the sun to the surface of the earth due to clouds, dust and water that reduce the production capacity of solar cells. On the contrary, if these radiations are reflected on the solar panels, they will increase the total energy output of solar panels [10,11]. However, many algorithms have been developed in this area, but there is still no perfect solar tracking system that can be used in all regions on Earth surface because of the changing climatic conditions from one region to another.…”

Design and implementation of fast and highly precise water magnetizer

“…In addition to a promising prototype that has open-source software, all the data are stored and exported with a timestamp for researchers and students, and more features will present in the article. To enhance the presented system, we suggest as for the future works; adding a monitoring and control system via internet of things (IoT) [30][31][32][33], or via long range (LoRa) [34,35], also supplying the system power with photovoltaic system as in [36,37]. In section 2, the relationship between the magnetic field and power of hydrogen (pH) will be explained, and the effect of temperature on pH will be presented in section 3, In section 4, the system technical design and implementation are discussed in detail.…”
