    Optimal Integration Of Renewable Energy Into The National Grid For Improved Power Supply Using Ann Based Supercapacitor

    Full text link
    The increasing global demand for clean and sustainable energy has accelerated the integration of renewable energy sources (RES) such as solar photovoltaic (PV) and wind power into national grids. In Nigeria, the adoption of RES is hindered by challenges including variability in power generation, grid instability, and insufficient energy storage capacity. These limitations often result in unreliable power supply, frequency deviations, and voltage fluctuations. This study presents an Artificial Neural Network (ANN)-based super capacitor control system designed to achieve the optimal integration of renewable energy into the national grid for improved power supply stability and reliability. The ANN serves as an intelligent controller capable of learning complex nonlinear relationships between renewable generation patterns, grid demand, and storage behavior, enabling adaptive and precise charge–discharge control of the super capacitor. The super capacitor, with its high power density and rapid response time, mitigates the effects of renewable intermittency by providing fast frequency regulation, voltage support, and peak shaving. Simulation results obtained from a MATLAB/Simulink model of the Nigerian grid integrated with RES demonstrate that the proposed ANN-based supercapacitor system significantly improves grid stability, reduces voltage deviation by up to 18%, and enhances renewable energy utilization efficiency by 25% compared to conventional storage control methods. The findings indicate that ANN-driven supercapacitor storage systems offer a viable solution for optimizing renewable energy integration, ensuring improved operational reliability, and supporting Nigeria’s transition towards a more sustainable power infrastructure. The results obtained were the conventional intermittency and rapid generation variability that causes unoptimal integration of renewable energy into the national grid for unimproved power supply was 52 MW. On the other hand when an ANN based super capacitor was integrated into the system, it instantly reduced to 47.5 MW and the conventional intermittency and Poor generation forecasting that causes unoptimal integration of renewable energy into the national grid for unimproved power supply was31MW. Meanwhile when an ANN based super capacitor was introduced into the system, it automatically reduced to28.3 MW. Finally, with these results obtained, it definitely meant that the percentage optimized integration of renewable energy into the national grid for improved power supply when an ANN based super capacitor was imbibed into the system was8.7%

The Majority of the participants had the opinion that social media news are credible based on timeliness, source, citations and credibility of the author or organization. Based on the findings of this study, the following were recommended; that necessary codes of conduct and ethics should be adopted by social media owners to guarantee credibility and accuracy of information. Media literacy should be encouraged among the users of social media to enable them control and determine what they do with the information that they receive over the media. It is recommended that effort should be made on the part of the audience to compare information obtained from social media with other available news sources before accepting or even fleeting the same information to other helpless users and many more

    Implementation of Fatigue Strength Analysis of Washing Machine Drum Using Von Mises Approach

    Full text link
    The fatigue strength analysis of washing machine drum was analyzed using von mises approach. The expected life time of the washing machine drum with respect to fatigue strain at the welded parts was successfully estimated using Miner’s rule. From the results obtained it was observed that increasing the speed of the washing machine from 400 to 2200 rpm resultedto decrease in its life time from 120 to 20 months and this were attributed to increase in stress – strain concentration and then fatigue failure of the welded parts. Autodesk simulation of the washing drum activities at speeds and temperatures ranging from 400 to 2200 rpm and 30℃ to 120℃ respectively increased the von mises stress of the machine from 62 to 549Mpa. The simulation shows that increase in speed and temperature of the machine drum, decreased the fatigue limits of the welded thin sheets. Node shell element result of the strains at front, rear, and middle of the welded parts of the drum produced varying results at speeds in the range of 400 to 2200 rpm. Higher strains values ranging from 11 to 278 Mpa. Were obtained in the middle of the drum were stress concentration was more, which could be as a result of location of greater washing activity than in the front and rear side of the cylinder with less strain values (-1104 to -58Mpa), increase in speed (400- 2200 rpm) and the loads (10 to 100kg) in the washing machine drum were observed to increase the strain effects at the rear, front and middle of the cylinder
