It consists of various renewable energy systems, including the photovoltaic system, biogas as a primary energy source, a fuel cell generator and a hydrogen storage unit, which can provide electricity to developing economies. As the photoelectric generator and the methane generator provide sufficient electrical energy during the day that covers the requirements of the different loads on the farm, while the excess energy is transferred to the electrolyzer for hydrogen production and storage, and when the load needs more energy, the electric fuel cells are turned on where the hydrogen is obtained from the energy storage unit. An energy management strategy was also proposed in this study as the newly developed network control and management system, and Matlab was chosen to undertake this task. Moreover, the RETscreen Expert software that enables to determine the optimum size that meets the potential demand along with the most feasible economic values and guarantees the highest system reliability. Therefore, three scenarios were proposed and tested, the first being the basic model which was a solar system with traditional batteries, the second a solar system, biogas with batteries, and finally, solar energy, biogas, and fuel cell with hydrogen energy storage unit. Technical analysis of the combined generation was also performed using Power world simulator to obtain constant frequency and voltage (stability conditions). The simulation results clearly show that the hybrid renewable energy system (HRES) consist of PV, bioenergy and small-scale fuel cell generator is a more economical configuration than single renewable energy systems with battery which has a total net cost of $ 473570, levelized cost of energy (LCOE) of 0.157 $/kWh and the lowest CO2 emission model that was 2.1 tons per year.","PeriodicalId":145183,"journal":{"name":"International Journal of Electrical Engineering and Computer Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136112600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It consists of a conventional power system, a renewable power system, power storage, load management, and a control system. However, different microgrid configurations do exist, be it conventional energy sources or hybrid energy configurations, which have been discussed in this research to achieve an efficient and cost-competitive power system configuration. The microgrids could improve the quality of service for the telecommunications industries in Nigeria. The study takes into account the diverse network architecture of eight possible configured network models, and the topologies were simulated and tested for economic optimisation on HOMER energy software. The simulation results show that if any of the options were properly studied and harnessed, a permanent solution to power failure at our base station would be achieved. Similarly, the cost analysis presented reveals that the installation and operating expenses of any of the options were relatively cheap when compared to conventional procedures, lowering the tariff cost imposed on customers. Consequently, it will lead to the development of robust, off-grid power solutions for telecom infrastructure, enabling continuous connectivity in remote locations, decreasing downtime, and improving the country's digital communication network.","PeriodicalId":145183,"journal":{"name":"International Journal of Electrical Engineering and Computer Science","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135592100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the main social demands, energy consumption is one of the factors with the highest growth, but technologies related to the theme have not developed at the appropriate pace to the context, especially observing that consumers have little or no information about their consumption data. The wide variety of electronic equipment is evident, therefore, the development of a system that allows the user to monitor the energy consumption of the equipment by only a low-cost sensor and with high precision is an interesting advantage. To this end, it is proposed the implementation of artificial neural networks to increase the accuracy of microcontrolled instrument connected via Wi-Fi, to provide reliable data that can be stored in the cloud and present consumption in real time.","PeriodicalId":145183,"journal":{"name":"International Journal of Electrical Engineering and Computer Science","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115065340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thereby, a Unified Power Quality Conditioner (UPQC), which is a custom power device is proposed in this work for improving the PQ of the overall network. The load side PQ issues is mitigated using the shunt compensator, while the source side PQ issues is mitigated using the series compensator of the UPQC. The active power to the load is provided from the PV system through a shunt compensator. The voltage level of the output obtained from the PV is improved with the aid of Re-lift Luo converter, which is a DC-DC converter of high efficiency and voltage gain. Moreover, in order to provide a stabilized voltage supply to the UPQC, an Adaptive Proportional Integral (PI) controller is selected and its gains are adjusted with the application of Fuzzy Logic Controller (FLC). The Decoupled Double Synchronous Reference Frame (DDSRF) theory is applied to derive the reference voltage and reference current for balancing source voltage variations and load current harmonics, respectively. The series and shunt compensators are controlled using Cascaded Type-2 FLC (CT2FLC). The effectiveness of the proposed PV-UPQC configuration in eliminating load current harmonics and source voltage fluctuations is evaluated on the basis of MATLAB simulations.","PeriodicalId":145183,"journal":{"name":"International Journal of Electrical Engineering and Computer Science","volume":"9 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114034540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
