Omorogiuwa Eseosa — 2019-09-07

Renewable energy resources from scholarly investigations has proved to be the safest and cleanest form of energy the world over but some countries are yet to tap into this most especially the developing nations. Nigeria as a country is blessed with abundance of renewable energy (solar, wind hydro etc.) yet the government has not fully recognised the relevance and benefits of this source to the economy. This works thus investigate critical reviewed journal papers on renewable energy sources with more emphasis on photovoltaic systems and their applications to power generation.

Analysis of Photovoltaic Array Strategies with Different Partial Shading Features

Deepali Khabia — 2019-09-28

Conventional energy sources are diminishing day by day and energy demand is increasing with rapid growth in industries. Therefore there is call for utilizing renewable energy sources such as solar energy, wind energy, geothermal energy etc. among various sources conversion if solar energy into electricity is emerging as popular form of renewable energy. Partial shading occurs on photovoltaic (PV) system due to passing clouds, trees, buildings, dust particles etc. Shading causes substantial reduction in power generation. In this thesis PV array configuration scheme is proposed. Five diverse photovoltaic exhibit configuration schemes: Series (S), Series-Parallel (S-P), Total-Cross-Tied (T-C-T), Bridge-Linked (B-L), and Honey-Comb (H-C), are conveyed out using 4×4 photovoltaic cluster under five distinctive concealing design cases Solar irradiance values taken are 1000W/m2, 800W/m2 and 400 W/m2 under STC 250 C. A bypass diode is connected in anti-parallel to each module to protect against phenomena of hot spot. An obstructive diode is associated in series. Imitations of all concealing cases are applied using MATLAB/ Simulink R2018b programming. When all is said in done, the got most extreme power results under all incomplete shading cases show that Total-Cross-Tied (T-C-T) setup has the best execution as indicated by other configurations. Among diverse concealing cases, section concealing (case 1) has most elevated concealing misfortune (308.8W). Mismatch misfortune is most noteworthy for arrangement (S) topology for case 5 sorts of concealing (44.23%). For case1, SP, TCT, BL, HC design have almost same worth Fill factor, that is 0.71, most noteworthy value. Series (S) design fill factor is 0.66. Lowest fill factor is appeared by arrangement parallel (S-P) topology in the event that 4 concealing example.

Performance Analysis of Intelligent Controller Based MPPT Connected PV System

I Vijaya Lakshmi — 2019-10-15

The need of generating power is increasing to a greater extent in the present day world. The conventional energy power plants like Thermal, diesel, hydro and nuclear etc., were in the position of reaching the power demand in the world but due to the extinguishment of fossil fuels and other necessary conventional energy suppliers, the entire world is waiting for a big alternative solution to overcome the above power crisis problem. Solar energy systems are best among the renewable energy resources in the world. The major problem of extracting maximum power from the solar systems has been resolved by different conventional MPP techniques. But to enhance the solar panel's effectiveness, an intelligent controller has been used as a MPPT system. As the solar Irradiation changes with respect to the change in weather conditions, the output power fluctuates a lot. This problem can be overcome by placing an intelligent controller in the MPP system and the proposed intelligent controller was simulated in MATLAB/SIMULINK software for different Irradiation levels.

Renewable Energy Statistics Outlook: The Worldwide

Farah Bani Affan — 2019-11-10

Demand on renewable energy resources has been highly increasing in the past decade; such resources include hydropower, wind, solar, waste and biofuel. In this paper, statistics are illustrated in the form of figures and tables showing the capacity and production trends for different forms of renewable energy all around the globe, highlighting the peaks. Some light is also shed on the public finance flows.

Temperature Sensors Development in the Chemical Industries

Farah Bani Affan — 2019-12-04

Temperature sensors have been of major interest, especially in chemical industries, in order to increase the quality of wide range of products. These devices are considered to be the eyes of the chemical processes, as they report the continuous changes in temperature. This literature based research paper evaluates six different developed types of temperature sensors, according to four most critical parameters. This assessment was limited to the sensor location and accuracy, the range of temperature measured, and to the size of the temperature sensor. It is concluded that the technological temperature sensors are the optimum technology to produce high quality products. For instance, the optical sensors showed a high level of accuracy and the fact that they have the facility of remote sensing.
