In this paper, a modified packed U-cell inverter is proposed to provide thirteen-level smooth waveform at the output. The proposed inverter uses eight switches and three DC sources, which is very less compared to the classical inverters. The efficient multi-carrier PWM switching technique is employed to control the operation of the inverter and to reduce the current harmonics. Simulations are carried out using Matlab/Simulink package to investigate the performance of the proposed inverter. The improvement in the output waveform and the reduced harmonic distortion are pointed out, which prove the efficiency of the proposed inverter.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123067621","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}

Source, load, and the contingency on both side have been considered for this investigation. It is found that disturbances can potentially deteriorate the controller performance and contribute to oscillation and resonance at DC bus. In this investigation, a small-scale multi converter-based DC microgrid is designed first, and case studies have been conducted with the traditional single-variable controller. Three methodologies including impedance scanning, fast Fourier transform (FFT) analysis, and time-domain simulation have been applied concurrently to check the small-signal stability on DC bus in DC microgrid. It is noticed that the disturbances at the same time on the source and load side are more influential than the single side disturbance. Besides, source-side voltage disturbance is also appearing significant, considered to the load disturbances. This analysis framework would help a researcher/planner in designing a stable multi converter-based DC microgrid.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"26 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123707918","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}

To do the analysis, a UK average Electric Vehicle (EV) and domestic battery have been established; called UKEV and UKBat respectively. The UKEV characteristics were determined by taking a weighted average from the five highest selling EVs in the UK. An arithmetic mean was found for the individual UKBat features from seven models available on the UK market. The UKEV and UKBat were compared under four scenarios. These are Ofgem’s two domestic electricity profile classes (PC1, PC2) and two existing time-of-use tariffs; one with two and the other with three rates during a day. At medium battery degradation rate, maximum annual savings for the consumer was estimated to be around £94 and £147 per year for the EV and battery, respectively.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129711928","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 charging time of EVs is seen as a significant hindrance to EV adaptation. There are two different charging methods: (a) Slow charging – via the domestic power supply and (b) Fast charging – via commercial charging stations. With high penetration levels of EV forecasted in the future, EV load would become a significant part of any utility load curve. Compared to other stationary loads connected to the grid, EV battery loads, on the other hand, are highly mobile in nature, i.e., the location of EV load is not specified in the distribution line throughout the day. Additionally, distribution systems are not rated for high overload capacities and are usually characterized by congestion zones in heavily populated areas (which would become worse with the addition of EV loads). Thus, the impact of EVs load o the utility grid must be analyzed both on the circuit level and system level. This paper discusses the power topologies used for EV charger realization, followed by the grid performance issues introduced by different EV charger topologies. The impact of EV load on grid power quality, power system equipment, and grid performance indicator are also explained in detail. Then the paper presents a brief review of different analyses and studies performed to assess the impact of higher EV penetration levels on the distribution side of the utility grid. Finally, strategies proposed to improve the grid performance by reinforcing the existing structure are discussed.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123804681","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 mainly studies the influence of harmonic current with different order and amplitude on the vibration response of permanent magnet synchronous motor. First of all, based on the current waveform under variable frequency power supply, combined with theoretical analysis, the order harmonics are determined. Secondly, the harmonic current injection method is used to analyze the influence of low order harmonic current on the vibration response of the motor. The simulation results show that the low order harmonic current can reduce the vibration response of the motor to a certain extent. Finally, the accuracy of the vibration calculation method is verified by the vibration test of an experimental prototype.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131615500","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 entry of electric vehicles unavoidably alters load profile, therefore affecting the voltage of customer load points and capacity loading of the distribution feeders and distribution transformers. The system reinforcement to accommodate the increased EV loads can be achieved by yearly sequential decision making, given updated information of the locations and amount of EV loads. The individual load profile can be simulated by a Monte Carlo Simulation. The objective function is to minimize the total cost associated with installing and dismantling control devices and energy loss over a planning period. The proposed methodology was tested with a 30-bus system. The results show that the optimal yearly schedule can keep the voltage profile and feeder and transformer loading within acceptable operating limits while minimizing the system total cost.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"15 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129488027","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}
