This mechanical energy of the transport system in the form of friction energy, potential energy of the weighted vehicles, heat energy of the tyre in contact with the road, sound energy of the vehicles and other sound energy related activities on the road is left unharnessed. However, this wasteful energy on this road could be utilizes into electrical energy through suitable approach that includes piezoelectric transducer QB220-503YB with dimensions (31.8×66.7×1.8 mm) at each of the carriageway in the road junction, utilizes the weight of moving vehicles with the aid of piston-spring pressure and then convert it into beneficial electric energy. This paper studied attempts to concentrate the possibility of taking advantage over traffic road junction by pressure in weighted form of moving vehicles and Pedestrians and in turn convert it to electrical energy using ramp coupled to piston-spring pressure arrangement and Piezoelectric material, stored the converted energy in the high performance battery for further public utilities, off national electricity grid. This is called Smart Traffic Road junction, an intersection of different cardinal roads network at a point. The case study, Traffic Road junction, was considered where wasteful energy much more than just a carriageway is more unnoticed. From the observation, it is noticed that the electric power is highest with the large truck weighing 2460kg, thus the 100 transducers at the four carriage lanes will produce about 102.612 kilowatt-hours. As known a LED street lamp consume about 60 watts-hour; so the produced amount of converted energy is sufficient to power 1710 number of street lights or appliances within the permissible range.","PeriodicalId":325937,"journal":{"name":"2020 IEEE PES/IAS PowerAfrica","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128321214","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}

Uganda as a developing country has put mechanisms in place to provide electricity to her people and be able to realize the national vision of 2040 and be able to address other SDGs by 2030. Solar PV mini-grids are emerging as popular alternatives to address rural electrification shortfall after other renewable energy mini-grid types proved desirable for some period. Uganda's expectations of renewable mini-grids are high with the Ministry of Energy and Mineral Development, the World Bank, and the Government of Uganda showing much interest to support the mini-grid development. This paper, therefore, looks at general mini-grid development and operation models and finds out arguments making renewable energy mini-grids popular at the expense of non-renewable based mini-grids. The methodology focuses on exploring ideas and formulating a hypothesis by summarizing, categorizing, and interpreting both the primary and secondary data. The paper concludes looking at the strength, benefits, and challenges of renewable mini-grids.","PeriodicalId":325937,"journal":{"name":"2020 IEEE PES/IAS PowerAfrica","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124605413","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}

In some cases, state-level legislative mandates called Renewable Portfolio Standards (RPSs) necessitate the use of storage to support renewable generation (e.g., solar, wind energy). At the federal level, the Federal Energy Regulatory Commission (FERC) has issued final Orders that stipulate fair and equitable competition rules for regional interstate transmission markets. In both instances, it is the investor-owned utility (IOU) entities that are financially responsible to either satisfy the state and FERC Orders or face noncompliance fines or tariffs. Unfortunately, utility investors do not have a reliable tool to assist in understanding the front-end installation costs or whole life cycle costs for electrical storage systems that service the electric grid. This paper proposes the use of multiple linear regression (MLR) techniques using R-Script to predict the total capital cost (TCC) and life cycle cost (LCC) of real-world energy storage systems (ESSs) derived from manufactures' design specifications and intrinsic characteristics of lead-acid, lithium-ion, sodium sulfur; and vanadium and Ainc-based Aow Aatteries.","PeriodicalId":325937,"journal":{"name":"2020 IEEE PES/IAS PowerAfrica","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114947282","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}

These loads draw non-sinusoidal currents and voltages from the utility supply generating harmful harmonics. Injection of harmonic currents and voltages into the utility supply affect the utility supply systems and customer's equipment connected at point of common coupling. Issues of power quality has become an important issue to both users and distributers of electrical power. Active power filters have proven to be an efficient method for power quality improvement and reactive power compensation in a system with harmonic related problems. This work present approach for design of shunt active power filter for harmonic compensation. Different traditional and modern harmonic solutions topologies are presented. Shunt active power filter is the most famous and used type of filter hence need to improve its performance. The generation of reference signal and control of shunt active power filter is considered in this work. Deadbeat control of APF in $alpha-beta$ reference frame and PI control for DC link voltage is presented, considering advantages of each controller. Three phase three wire system supplying nonlinear load is used to test performance of the proposed filter. It is implemented on MATLABSimulink and results discussed.","PeriodicalId":325937,"journal":{"name":"2020 IEEE PES/IAS PowerAfrica","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134352394","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}

Technical and non-technical losses are the contributing factors of electrical power losses. Technical losses are regarded as the electrical system losses which are caused by network impedance, current flows, and auxiliary supplies. Electricity thefts, measurement system errors and non-payments of bills are the contributing factors to non-technical losses which resulted in revenue loss increasing every year in Eskom. The smart grid with smart meters implemented promises to be an effectively integrated technology to address the issue of non-technical losses. To analyze the effectiveness of smart prepaid split meters implementation on Eskom distribution networks, a quantitative random sample assessment of 334 respondents was evaluated using a self-administered questionnaire. The collected data was analyzed with Statistical Package for the Social Sciences software (SPSS) version 26.0 and Microsoft Excel 2016 version to achieve multi-objective decision-making for smart prepaid split metering effectiveness for both utility and customer satisfaction. The different inferential statistics techniques used include regression, correlations, multifactor analysis (MFA), and chi-square goodness of fit test to interpret the p-values, identify the change-point, detect the trend and to correlated best fit time series for decision making. The findings showed that smart metering usage as emerging technology has offer multiple benefits to utilities and provide a possible long-term solution to many of the power-related problems utilities face.","PeriodicalId":325937,"journal":{"name":"2020 IEEE PES/IAS PowerAfrica","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123456160","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}
