In this research, the Mathcad program and the Professional Simulator 8 were employed, the specific fuel consumption (SFC) technique is used to determine the efficiency of production expenses, as well as the direct and indirect methods to calculate the boiler efficiency. The results reveal that 4.09 IDR/kWh reduction in primary energy expenses could be achieved (0.65%). Co-firing fuel will undoubtedly have a significant impact on the boiler's performance, therefore when using 100% of coal as a fuel, the boiler efficiency value is 63.38% (Direct Method), while using the Indirect Method will produce up to 82.24%, respectively.

The public transportation and commercial vehicle sectors have already begun implementing electric vehicles to meet the emission reduction requirements that are being put in place around the world. It is time that the commercial shipping sector joined them by working towards the electrification of ships and possibly using large batteries as fuel. However, there are some concerns with the ability to charge batteries during long voyages and the weight addition that large batteries would bring. One way to reduce GHG emissions in port is by cold ironing a ship or plugging in a ship to an onshore power source instead of using onboard diesel generators when ships are at port. This is effective because the main propulsion does not need power while in port. However, to ensure that the integrity of the onshore grid is not affected by this additional heavy load that may arise from the loads onboard the vessel, these loads must be analyzed before connecting them to the onshore grid. In this paper, to address these issues, this paper aims to investigate the power quality of the distribution side of T/V General Rudder, a Texas A&M University Galveston's owned ship. Based on the distribution system's harmonics content and power quality, the authors propose an active filter on the secondary side to reduce the Total Harmonic Distortion (THD). The proposed filter results in a decrease of 90% total harmonic distortion, leading to increased efficiency and system performance. Further, the impact of load on the onboard diesel generator and the onshore electrical grid is also examined.","PeriodicalId":101715,"journal":{"name":"2021 IEEE Conference on Energy Conversion (CENCON)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124478852","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 paper focuses on harvesting waste energy during military operation in the field and converting it into electrical energy that could supplement batteries used to power electronic devices. In this study triboelectric energy generators were fabricated from nine army textiles and tested for use in impact energy harvesting (for harnessing solider motions such as walking and rucking) and wind energy harvesting (for harnessing wind-driven fluttering motions of shelters or parachutes). It was found that triboelectric generators consisting of army textiles having nylon fibers with water repellent side and back coating, paired with Polytetrafluoroethylene (PTFE) layers performed best in impact tests, followed closely by an army textile with an equal proportion of nylon and cotton fibers and wrinkle-free finish coating. For the wind test, an army textile having nylon fibers and fluorocarbon coating paired with PTFE layers performed best. It was also found that the use of silver particle-loaded Polydimethylsiloxane (PDMS) electrode layers improved the performance of the generators relative to copper tape electrode layers. All textile samples performed better in impact testing than in wind. The maximum average voltage recorded for the impact tests was 7.8 V while the maximum recorded for wind testing was 1.3 V. Finally, a triboelectric generator was integrated into a soldier's boot and the energy harvesting performance was evaluated for different motions of the wearer including walking, rucking, and running. The output voltage increased with increasing speed and angle of inclination for all operations. The maximum voltage recorded was 0.7 V for walking at 2 mph and 5% inclination, while it was 2.22 V for rucking at 6 mph and 2.33 V for running at 10 mph.","PeriodicalId":101715,"journal":{"name":"2021 IEEE Conference on Energy Conversion (CENCON)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132340755","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 Malaysian government aims to reduce greenhouse gas emissions by 45% on 2030. The Malaysian government is promoting energy-efficient vehicles (EEV) including future electric vehicles (EV), and aims to have 100% of EEV on-road by 2030. With the implementation of EV policies in Malaysia, these policies will act as an agitator for the mass adoption of EVs in Malaysian usage. However, from the viewpoint of the power system, EVs are additional loads when connect to the power grid. The massive penetration of charging station (CS) load has negatively impacted the distribution system, especially on the power losses. Hence, this situation has led to the need for unifying rules for the distribution system to accommodate this additional charging demand. In this research, the mitigation proposed is to implement optimal placement and sizing of multiple capacitor banks (CBs) for medium and low voltage distribution network systems optimized using the metaheuristic technique. The distribution system, CS and CBs are modelled using MATLAB environment. The metaheuristic technique used is Lightning Search Algorithm (LSA) and Modified Lightning Search Algorithm (MLSA) due to effectiveness from past research. Based on the simulation result, the MLSA method will best minimize the power losses at the practical 69-bus radial distribution network system. The study has proven that the optimal placement and sizing of variable CBs could reduce power loss. Furthermore, the results demonstrate that the multiple of CBs can provide a superior solution compared to a single CB. Hence, it concluded that the multiple CBs with the assistance of the MLSA method are the most suitable to be implemented in reducing power losses in distribution systems due to the massive penetration of EVs load.","PeriodicalId":101715,"journal":{"name":"2021 IEEE Conference on Energy Conversion (CENCON)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128220169","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}
