One of the recent emerging technology which makes the system nonlinear is electric vehicle charging stations. This research work aims to optimize the PI controller with a voltage-oriented controller-based Vienna rectifier for electric vehicle charging stations (EVCS). With the trial and error method for EV charging stations, the PI controller parameters K_p and K_i values, the error values such as integral square error (ISE) and integral absolute error (IAE), system parameters such as rise time settling time, and peak overshoot values are extremely high in the Vienna rectifier based VOC system. Due to the increased system parameters, the stability of the system has been reduced, which approaches a reduction in the system efficiency. The system parameters must be mitigated to provide stable operation to overcome the aforementioned issues with EV charging stations. In this research work, the PSO optimization-based PI controller for EV charging stations has been proposed. The proposed PSO-PI controller optimizes the control parameters and reduces the error values to make the system more stable. The proposed system is simulated and optimized using MATLAB software. The proposed PSO-PI controller-based EV charging station improves the system stability 12% more than the existing VOC controller with Vienna rectifier for EV charging stations.","PeriodicalId":6762,"journal":{"name":"2021 IEEE 19th Student Conference on Research and Development (SCOReD)","volume":"25 1","pages":"356-361"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86963389","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}

During the handover between different RATs occurred (Inter-RAT) in 5G NR heterogeneous environment, the process for UE allocation to the right network slice should be handle in a manner way to maintain the performance from the previous network slice. This paper aims to review the Inter-RAT handover mechanism approach for network slice selection in 5G environment. Review process will investigate the handover procedure works, then we will go through the mathematical theories used for modelling the network slice selection mechanism for Inter-RAT handover. Lastly, we will compare the theories and discuss the benefits in term of optimization and performance based on the selected criteria. With the purpose of limiting our scope to our main goal, we considered only papers published in conferences and journals between 2011 and 2020. A selected paper must discuss the network slicing Inter-RAT handover mechanism in dealing with a 5G technological issue. We will focus on works included only Inter-RAT handover in 5G, the handover procedure, selected criteria and mathematical theories used for optimization and performance in network slicing. The findings that will be discuss in this paper is the mathematical theories used in modelling the network slice selection mechanism during Inter-RAT handover by focusing on optimization and performance based on the selected criteria in 5G NR heterogeneous environment. This paper will contribute the systematic review around network slice selection mechanism during Inter-RAT handover.","PeriodicalId":6762,"journal":{"name":"2021 IEEE 19th Student Conference on Research and Development (SCOReD)","volume":"8 1","pages":"311-316"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79408840","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}

A simulation model was developed and validated concerning the simulated of point absorber motioned in a previous study; this study compares tension methodologies for point absorber with moorings lines using simulation approach. The purpose of this paper is to propose a mooring lines simulation approach that is suited for a one-body and two-body point absorber thorough examination of the heave motion response and, tension analysis of mooring lines coupled on the device and on seabed. The case study is a cylindrical, floating point absorber with one, two, three and four distributed mooring lines with catenary and taut configurations. The dynamics of the point absorber were simulated and analysed in the time domain using different configurations of mooring lines using Computational Fluid Dynamic (CFD) simulation approaches were compared. A thorough response analysis is undertaken using a Malaysia low wave condition in shallow water. The results were compared to the assessed for both one and two-body point absorber methods. The simulation process employing a two-body with four mooring lines recommended as the preferred method for capturing the interaction between the WEC system's components, which has been demonstrated to be critical for heaving response evaluation. The average maximum tension on four mooring lines with catenary configuration is preferred to have less tension with high heaving response of the device compared to others. The findings showed that a two-body point absorber with four catenary mooring lines average maximum tension of 700 N is more efficient at absorbing low wave heights than a single body.","PeriodicalId":6762,"journal":{"name":"2021 IEEE 19th Student Conference on Research and Development (SCOReD)","volume":"53 1","pages":"233-238"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85269955","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}

A negative impact has made local farmers struggle to find their means of income other than selling their crops to their customers. The customers have had difficulties searching for good quality fresh produce other than from the supermarket. The purpose of this paper is twofold: firstly, to assess the manual and existing system on how consumers acquire their fresh produce during the Covid-19 pandemic, to design and implement a delivery system for local farmers to vend their fresh produce through a mobile application; and secondly, to test and evaluate the usability and functionality of the online farmers' market application. The existing mobile applications have changed everyone's approach in acquiring the daily essentials that the pandemic has brought. Therefore, the idea of developing an online marketplace for local farmers resulted in the proposed application, which will be explained in this paper. Rapid Application Development (RAD) was used as the methodology for the development of the eMarket application. A survey was conducted via Google form for twenty local farmers and another twenty potential customers during the pre-development stage. It was to collect data on the users' opinions regarding the proposed application. We then conducted the usability testing through Google form to collect the users' feedback on the eMarket application. Ten local farmers from Matang's market have participated in the testing phase. Additionally, ten students from a local university participated as potential customers in the usability testing. As a result of these testings, we have developed a usable farmer's market application that has been well-received by local farmers and customers.","PeriodicalId":6762,"journal":{"name":"2021 IEEE 19th Student Conference on Research and Development (SCOReD)","volume":"13 1","pages":"30-35"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73488691","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}

Many electric utilities and practitioners are reluctant to apply IEC 62305-2 due to the lack of direction to perform the lightning risk assessment for the substations. Therefore, the electric utilities and practitioners usually select their preferred methodologies based on IEEE 998 which lacks coherence while performing the lightning protection design for substations. This study will demonstrate the applicability of the lightning risk assessment for substations based on IEC 62305-2. The dimensions such as lightning collection areas for substations can be determined via computer-aided design (CAD) software. These site features will be used for the lightning risk assessment by similarly representing the substations as the building structures. It is shown that some of the ambiguous risk factors such as loss reduction factor due to physical damage depending on the risk of fire or explosion and injury loss value due to loss of internal systems which have a significant gap between ranges of risk values will dominantly influence the variation in the results. Besides that, the lack of selection criteria and the vagueness of risk values that are used to represent the actual substations case are highlighted. Therefore, this paper has shown some major risk components usually appeared in substations. However, the individual risk factor values of each component shall be revisited as some of the dominant ambiguous risk factors may contribute towards the misrepresentation of the results.","PeriodicalId":6762,"journal":{"name":"2021 IEEE 19th Student Conference on Research and Development (SCOReD)","volume":"4 1","pages":"218-223"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87228762","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}
