The ultimate choice is significantly affected by the conversion efficiencies, efficacies, useful working hours, life cycles, harmonics, and power factors of light lamps. An experimental study has been carried out to measure voltage and current harmonic distortions generated by various commercial fluorescent tubes, compact fluorescent lamps (CFL) and light-emitting diodes (LED) array lamps. The experiments were conducted using the conventional utility Pakistan Electric Power Company (PEPCO) source and an autonomous generator set Total Harmonic Distortion (THDv ≤ 2) to observe authentic power losses linked with harmonics. According to the results, the power loss range caused by distorted power factor is (30 to 35%), (1.5 to 28%), and (1% to 5%) for CFL, tube lights, and LED, respectively. The presence of high order harmonics leads to increased power utilization beyond the rated capacity, thereby augmenting the losses. Based on a comprehensive parametric analysis of a wide range of lamps, LED lamps emerge as the optimal choice for power conservation and environmental preservation. This suggests the need for frugality adaptation in conjunction with enhancing machine efficiency, efficient power end-use, and energy conservation practices for the purpose of conserving electricity.","PeriodicalId":36842,"journal":{"name":"Technology and Economics of Smart Grids and Sustainable Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136346907","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 is convenient to add another energy source to solar along with wind energy sources since these RESs could not be tapped continuously. Fulfilling the electric load demands with higher unpredictability might not be practical with stand-alone energy systems. Thus, to overcome the stand-alone energy systems’ weaknesses, it would be highly significant to amalgamate one or more energy systems. To provide expanded system effectiveness together with a greater balance in power supply, generally, two or more energy sources are comprised in a Hybrid Renewable Energy System (HRES). To produce electricity, the energy from wind and biomass is utilized in the proposed methodology. The rectifier is utilized with the inverter since the inverter operates with the DC input source. The Adjustable Step Size Maximum Power Point Tracking (ASS-MPPT), which regulates the output voltage by tuning the pulse width, is deployed in the inverter to attain a response for power control. By amalgamating the generation energy from wind as well as biomass systems, a Hybrid Power Generation System (HPGS) has been proposed. In the experimental evaluation, the technical feasibility of incorporating wind along with biomass systems for the needed demand has been analyzed. The experiential outcomes proved that to gratify the energy demands, higher efficiency could be delivered by the proposed hybrid system.","PeriodicalId":36842,"journal":{"name":"Technology and Economics of Smart Grids and Sustainable Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634643","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 developing countries, electricity depends mainly on non-renewable thermal resources such as coal or gas. Once these resources are used up, they cannot be replaced, which is a major problem for humanity. Renewable energy sources such as solar and wind power are clean, safe, and inexhaustible. However, solar energy is dependent on sunlight and wind power is unpredictable, so it's a good idea to combine them. This study, we present the SDT streetlight design, and implementation of a solar PV and wind turbine hybrid system to obtain the electricity for streetlights. The HOMER software was used to determine the cost of energy and performance, which provides investments of feasibility. Compared with the streetlights using power from standard electrical grid the proposed streetlights can save the electricity consumption of 15,592,800 kWh/y and reduce the CO2 emission of 6,704,904 kgCO2. In addition, the residual electricity can be resold through the smart grid and make the city smarter and more sustainable, reduce their carbon emissions and reimagine their travel and businesses for a net-zero world.","PeriodicalId":36842,"journal":{"name":"Technology and Economics of Smart Grids and Sustainable Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135405495","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}

DG reactive power control is of one the solutions for this problem. The purpose of this paper, in addition to controlling the bus voltage, is to share reactive power between the DG resources and to maintain the maximum active power level produced by the DGs. Reactive power sharing issues are unavoidable due to the difference in impedance of the DGs feeders and the different classifications of the DG units in the conventional drop control scheme. In this paper, reactive power sharing among generation resources are used to improve voltage stability. Virtual impedance method has also been used as one of the methods of reactive power sharing between sources to show and compare reactive power sharing methods between DG sources. In order to show the voltage improvement in this paper, the stability index L_index has been used. The proposed L_index has been confirmed against the existing methods for evaluating voltage stability using the reactive power sharing method in this study. This study is carried out in conjunction with an islanded microgrid model IEEE 38-BUS, the voltage stability of the corresponding microgrid buses has been shown. Voltage stability is achieved by reactive power sharing among distributed generation sources and is demonstrated in this study.","PeriodicalId":36842,"journal":{"name":"Technology and Economics of Smart Grids and Sustainable Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135253332","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}
