One type of battery that is often used in the implementation of renewable energy is lead-acid batteries. Accurate estimation of the SOC (state of charge) value is one of the important parameters in the design of a BMS (Battery Management System). Accurate determination of the estimation of the SOC value is necessary to avoid the battery operating in an over charge and over discharge state. One method of estimating SOC that is quite easy and often used is Coulomb Counting. The determination of SOC estimation by this method is carried out by adding up the incoming charge or the charge coming out of the battery within a certain period of time. Charge summation can be done by summing the current in the battery, both at the time of charging and discharge. In this research, SOC monitoring tool was designed using the coulomb counting method to monitor the SOC value of the battery both at the time of charging and discharge. In its implementation, this method is very dependent on the accurate initial SOC value and the accuracy of the current sensor used. The type of current sensor used in this SOC monitoring tool is ACS712 which has good accuracy. Based on the results of the tests carried out, the amount of charge on the battery is directly proportional to the SOC on the battery itself.","PeriodicalId":326314,"journal":{"name":"2022 10th International Conference on Smart Grid and Clean Energy Technologies (ICSGCE)","volume":"10878 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114693906","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}

This is primarily due to a transition towards electric vehicles (EVs) from internal combustion engine- based modes of transportation. Batteries are the most crucial component in EVs, constituting a significant share of the price of the vehicle. With usage, batteries degrade, thereby, limiting their ability to store energy which adversely impacts the driving range offered by EVs. Therefore, the need is to study the deterioration of batteries in electric means of transportation. We have created data-driven models to monitor battery health, predict the deterioration in batteries and give insights to the EV owners to make better decisions. The dataset used in this study is published by Sandia National Labs (SNL). It is a result of experiments performed on NMC cells. We present a comparison of three models - multiple linear regression, support vector regression, and artificial neural network for battery health monitoring with mean average percentage error (MAPE) of 1.99, 0.74, and 0.72 respectively.","PeriodicalId":326314,"journal":{"name":"2022 10th International Conference on Smart Grid and Clean Energy Technologies (ICSGCE)","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117307736","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}

Conventionally, diesel generators operate at a constant speed and work at a particular minimum load. Constant speed operation is intended to keep the system voltage frequency stable. However, this can reduce generator efficiency when load demand is low. Operating a variable speed to the diesel generator can be used to reduce the fuel consumption (inefficiency) of the generator. The choice of PMSG as a generator in the DEG system is made because PMSG has several advantages. In the DEG control method, the most popular is PID control, but it isn’t easy to achieve better performance. Based on the results from the related research, fuzzy logic-based control is an effective method. This study presents the optimal control modeling and simulation of DEG on variable speed operation using Permanent Magnet Synchronous Generator (PMSG) with Fuzzy-based control to achieve better system performance based on load changes. The result showed that operating the variable speed could increase the efficiency of fuel consumption by up to 21.41%. In addition, fuzzy control can achieve a faster settling time and minor overshoot than the PI control.","PeriodicalId":326314,"journal":{"name":"2022 10th International Conference on Smart Grid and Clean Energy Technologies (ICSGCE)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114772179","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 this study, the numerical simulation method is used to calculate the fuel concentration distribution by changing the pilot swirler stage angle in the concentric staged combustor. For the distribution of fuel concentration, the results revealed that the turbulent kinetic energy of the flow field and the atomization and evaporation process of the fuel are affected by the structural change of the pilot swirler stage. The vaporization of the liquid-phase fuel and the gas-phase fuel concentration in the central recirculation zone of the combustion chamber increase with the decrease of the number of swirls, which is beneficial to the combustion of the combustion chamber when the high temperature rises. The results provide valuable insights into the fuel concentration flow characteristics in the concentric staged combustion chamber.","PeriodicalId":326314,"journal":{"name":"2022 10th International Conference on Smart Grid and Clean Energy Technologies (ICSGCE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122002632","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}

Proportional-Proportional-Delay (PPD) is a new type of predictive controller. Compared with the existing predictive controllers, it has the advantages of less computation and higher bandwidth, and it can theoretically realize deadbeat control. However, in the actual digital system, the excitation voltage output by the PPD controller is limited by the limiter module in some working conditions, which reduces the response speed of system. This paper first analyzes the mechanism that the limiter module affects the dynamic characteristics of PPD controller, and deduces the most seriously affected working conditions. Then, based on the area equivalent principle of excitation voltage, a strategy for improving the dynamic characteristics of PPD controller in the actual system is proposed. The core idea of this strategy is to allocate the limited excitation voltage to the modulated wave of the subsequent switching cycle equivalently. And before the grid current is equal to the reference current, the modulated wave is controlled to run at the limit maximum capacity of the limiter module. Finally, an experimental prototype was built to verify the proposed strategy.","PeriodicalId":326314,"journal":{"name":"2022 10th International Conference on Smart Grid and Clean Energy Technologies (ICSGCE)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124172976","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 multi-input DC-DC converter is one of the proven solutions that can be applied to multi-generation systems. In this research, simulations will be carried out to evaluate the performance of multi-input DC-DC converters with perturb and observe MPPT algorithm in off-grid hybrid PV-Wind with battery and supercapacitor energy storage based on solar irradiance intermittencies conditions. From the results, it was found that a multi-input DC-DC converter can rapidly lower ripple voltage on the load side from 12% to 1 - 2% in consequence of intermittent irradiancy even without the implementation of the algorithm on wind turbine output. Also, overshoot and undershoot of the system can be absorbed by the supercapacitor and stored effectively by the battery so that power losses can be reduced. Therefore, the multi-input converter with the proposed Perturb and Observe algorithm can be used as one of the solution concepts for hybrid renewable energy electrical systems.","PeriodicalId":326314,"journal":{"name":"2022 10th International Conference on Smart Grid and Clean Energy Technologies (ICSGCE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116886813","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}
