The Sri Lankan Power System is taken as a case study. Due to the high penetration of wind and solar injection to the Sri Lankan power system, the inertia of the system is reduced drastically. The dynamic stability of the system due to high solar power penetration, is first discussed. The problems of the current system and the repercussions of such problems to the power system are then discussed related to the stability of the system where there is severe machine tripping. The paper also points out the remedial action needed to be taken in order to increase the power quality of the power system. The main remedial actions addressed in this paper are Battery Energy Storage Systems (BESS) and supercapacitors. In the third section of the paper a discussion is done on the BESS systems that are already installed in the world and how they are incorporated to achieve dynamic stability.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"37 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":"127362488","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}

Such networks are inherently stochastic, partially observable, and suffer from noisy or corrupt data. This paper proposes a fault detection method based on Bayesian inference paradigm and employs its corresponding graphical representation, that is Bayesian Belief Network (BN), to detect faults. The BN takes advantage of causal data produced by a distributed state estimation algorithm and correlational redundant data gathered from various devices to overcome uncertainty in making plausible decisions about the status of the system. Simulation results prove the value of the proposed technique in improving the reliability of conventional protection and relaying schemes.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"50 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":"122147532","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}

Based on cascaded control structure, combination of CNMPC and ISMC is proposed for both outer and inner control loops. Low pass filter is used to extract the equivalent of the discontinuous switching of ISMC so that the outputs of ISMC and CNMPC are added. Moreover, it is mathematically illustrated that the equivalent of ISMC is actually the same as the magnitude of disturbance. The performance of the proposed controller is verified through series of simulation tests. The combined controller shows robust response for parameter uncertainty and external disturbances such as dc current from PV. It is also shown that the grid current total harmonics distortion(THD) is within the international standards.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"258 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":"116191632","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}

Due to its versatile opportunities, Photovoltaic (PV) installations are becoming more widespread. Unlike the conventional generation systems PV is located closer to the load centers. This gives possibility of injecting PV at optimal locations to minimize system losses and improve voltage profile. Appropriate location and size of PV is vital for the stability of the system. This paper, considers different voltage stability indices to determine precise PV location, explores effects of PV sizing and impact of PV power factor fluctuations. To validate the stability of the proposed scheme, simulation is done for IEEE 33 bus system and IEEE 14 bus system with DigSilent. When system is optimized it showed a great improvement to the voltage profile with considerable loss reduction.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"17 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":"114807704","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}

Finally, taking XLPE (Cross linked polyethylene) cable on the high-voltage side of transformer as variable, the influence of XLPE cable on the overvoltage generated by switching no-load transformer is studied, and suggestions for suppression are put forward. The results show that obvious overvoltage of no-load transformer will be produced in the process of power plant grid connection. Under the switching angle 00, the maximum overvoltage can reach 1.69p.u. The length of XLPE cable has no obvious effect on excitation inrush current, but has influence on overvoltage.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"15 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":"128060589","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}

And the fundamental frequency measurement is important for synchronous sampling. However, due to the existence of harmonic components in the voltage/current signal, it is difficult to accurately measure the fundamental frequency of the signal for the traditional frequency measurement method. This paper proposes a new synchronous sampling architecture to realize the accurate fundamental frequency measurement for the signal. In the developed scheme, the frequency refinement method is adapted to solve the problem of signal discontinuity in discrete Fourier transform (DFT). Then the one-dimensional search method is used to accurately measure the fundamental frequency. In the experimental results, the synchronous sampling algorithm has a large signal frequency measurement range of 10 to 400 Hz with an error of less than 0.001 Hz + 0.01% * fundamental frequency. The wideband synchronous sampling proposed in this paper achieves high measurement accuracy.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"1 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":"125476475","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 context, a hybrid system topology, based on a fuel cell, a supercapacitor, and a DC/DC boost converter, is adopted so as to achieve a high efficiency lightweight drone platform. System components are first sized according to the drone mission requirements and the electric sources characteristics. For power management purposes, a frequency separation-based approach is adopted to share the requested power between the two sources. Indeed, the flight power demand profile is split into high and low frequency components. In this context, the fuel cell is controlled with the DC/DC boost converter to handle low frequency components while the supercapacitor supplies or absorbs all the power peaks. Simulations are carried out using a real power profile extracted from an experimental flight test of a small hexacopter. The achieved results clearly show that the proposed power management strategy enables extending the fuel cell lifetime inducing faster response and therefore improving the drone maneuverability.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"47 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":"115832398","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}
