Techno-economic assessment of installing a grid-tied rooftop solar PV (RTSPV) plant at SinoAfrica Joint Research Center (SAJOREC), part of Jomo Kenyatta University of Agriculture and Technology (JKUAT), was done. The energy demand profile for 2019 for the site was determined, and it was found that a 31.7 kWp RTSPV system could meet the demand. The estimated energy produced by the RTSPV system was 4S.S2SMWh/year. The specific production, capacity utilization factor, and the performance ratio obtained were 1541 kWh/kWp/year, 17.5 %, and S3%, respectively. The economic analysis of the project showed that the total project cost was USD 30066. S5. The Levelized Cost of Electricity (LCOE) of 0.10 USD/kWh and Discounted Payback Period ($mathrm{T}_{mathrm{D}mathrm{P}}$) of 4 years obtained indicated that the development of a grid-connected rooftop solar PV system for the JKUAT, SAJOREC area would be technically and economically viable.","PeriodicalId":371237,"journal":{"name":"2022 IEEE PES/IAS PowerAfrica","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129136401","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}

Some researchers are identifying these traits as capable of improving the dependability of grid networks in the event of significant outages. However, MGs have inherent voltage and frequency fluctuations that often require energy management systems (EMS). While a lot of research has focused on three-phase systems to solve these challenges, the authors of this article consider a single-phase DER interconnected system simulated with MATLAB/Simulink Power System Blockset. The simulated load model is improved to a mixed load that uses two cascaded Second-order Generalized Integrator (SOGI)-based quadrature-signal-generators (QSGs) Phase-locked loop (PLLs) for phase matching. The performance of the improved load model is verified through a group of interconnected prosumers in an off-grid environment with consideration for disaster outage situations, each running a proposed BESS SOC based EMS. The results point to the prevention of power outages for prosumers with a critical SOC over a three-day simulation period, which could help with disaster recovery.","PeriodicalId":371237,"journal":{"name":"2022 IEEE PES/IAS PowerAfrica","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117257003","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}

Battery-operated cooking devices (eCookers) offer a clean, affordable, and reliable alternative to biomass cooking. However, in-field studies have yet to quantify the charging and discharging behavior of eCooker batteries, and how the introduction of novel cooking practices that involve charging a battery to cook will impact consumer adoption. This paper details the design of a low-cost and open source eCooker smart meter, which combines the remote capture of battery status data with qualitative consumer behavioral data using a smartphone. This streamlined data collection technique was shown to provide significantly expedited data collection and automated data analysis required for accurate power system modelling to inform the potential upscale of eCookers in developing countries, and in particular Sub-Saharan Africa (SSA) where clean cooking access rates are the lowest.","PeriodicalId":371237,"journal":{"name":"2022 IEEE PES/IAS PowerAfrica","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126123024","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}

For this reason, there is a need to extend electricity to these rural areas by exploring the available renewable energy source in Nigeria. This work was carried out using a remote community in Nigeria as a case study. The electrical load survey of the community was carried out to determine the load demand of the area. The value of S4.6 kWh was obtained as the daily load demand considering the future expansion that will be included in the nearest future, hence the load curve was determined. This work also considered the modelling and optimization of the system components prior to the economic analysis of the project. The BAT algorithm was used as an optimization tool to determine the number of PV modules, battery banks and the capacity of the inverter to be used. At different scenarios, the number of the components varied with the days of autonomy of the energy storage system and PV power rating. The Levelised Cost of Energy (LCOE) was determined to be 0.5034 ${$}$/kWh. Finally, the results were validated against the HOMER software.","PeriodicalId":371237,"journal":{"name":"2022 IEEE PES/IAS PowerAfrica","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124455907","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}

The energy produced from wind source varies proportionally to wind speed, if the wind generators are connected to the grid system, it may cause power fluctuations into the grid side and even to the consumers. Installation of electric energy storage system (EESS) between wind generator and grid system can reduce the wind intermittency effects on the power quality. The storage system can be configured into hybrid configuration to enhance the performance of each storage technology. This paper proposes a well-designed and optimized HEES system connected between wind generator and grid system. Economic feasibility of HEES system composed by a lithium-ion battery bank, supercapacitor bank and pumped hydro is conducted. The system is optimized and simulated by HOMER software. After simulation, the results show that at the average annual wind speed of 8m/s, the economics metrics are higher. The internal rate of return is 29%, Net present value is 480${$}$ Million, return on Investment is 25%, levelized cost of electricity is 0.0340${$}$/kWh and payback period are 3.5 years. While at annual average wind speed of 4. 90m/s the internal rate of return is 17%, the Net Present Value is 216 million, the return on investment is 13%, levelized cost of electricity is 0.0244${$}$/kWh and the pay period is 5.8 Years. To make a HEES project more profitable, the site must have a higher annual wind speed.","PeriodicalId":371237,"journal":{"name":"2022 IEEE PES/IAS PowerAfrica","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122479463","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}
