Existing literature has demonstrated its effectiveness in improving frequency regulation in terms of frequency nadir, especially when a frequency deadband is further incorporated. However, the mathematical relationship between the virtual inertia and frequency nadir is already sophisticated by itself and might be even more complicated due to the nonlinearity introduced by the frequency deadband. Therefore, it is difficult to either quantify the improvement on frequency nadir or determine the decisive parameters that contribute to this improvement. To address this challenge, an artificial neural network (ANN) is employed in this paper to act as a computational surrogate model of the GCC that can map the system design parameters (i.e. frequency deadband, dc-link voltage and etc.) into the variable that characterizes frequency regulation (i.e. frequency nadir). The ANN model is trained by 500 labeled data points and tested by 50 unlabeled ones. The output of ANN is compared against a detailed simulation model in MATLAB and achieves a less than 0.006% error. Finally, the results produced by ANN also show a 14 times higher accuracy than mathematical calculation.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"399 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115995316","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 switching frequency of the IGBT is getting faster and faster, the pulse width modulation period is shorter. Under a limited sampling rate, sampling points are sparse in one cycle. This paper analyses the frequency spectrum of the ripple and the error of the calculation method based on frequency domain under sparse sampling, designs a calculation method based on time domain exponential function, realizes the high precision calculation of current and voltage under sparse sampling, and provides a reference solution for the calculation of DC system energy metering and the current and voltage calculation in protection and control devices. Finally, taking the Buck DC/DC output energy metering as an example, the accuracy of this electrical metering method and the method based on frequency domain is compared and analyzed. The results show that the relative error and absolute error of the algorithm are small under the same sampling rate.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"28 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131540419","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, a star-structured LC resonant SC equalizer is proposed to equalize the unbalance cell voltages completely within minimum time. An inductor is used in series with each capacitors of the proposed equalizer. The designing procedure confirms the zero-current-switching (ZCS) and zero-voltage-gap (ZVG). ZCS reduces the switching loss by removing the current spike during the switching periods. ZVG confirms the complete voltage equalization among the cells. The star structure reduces the balancing time by creating the direct any-cell-to-any-cell paths for exchanging the excess energy among the cells. The MOSFET is used as switches and only a pair of complementary PWM signal is used to operate the whole circuit. The proposed equalizer is validated in both simulation and experimentally. Results show that the proposed equalizer performs better compare to the conventional equalizers especially in balancing time and complete equalization.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"276 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127550428","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}

It is desirable that an IPT charger can be configured with the initial constant current (CC) and the subsequent constant voltage (CV) outputs as the battery requires, combating constr-aints of the loosely coupled transformer (LCT) parameters without sophisticated control schemes. Meanwhile, a near resistive input impedance and soft switching for the whole battery charging process can be permitted. To meet these requirements, this paper systematically analyzes the characteri-stics of some existing compensation topologies and proposes two hybrid IPT structures to realize the configurable CC and CV outputs in regardless of the constraints of LCT parameters. Due to the different output filters, a hybrid IPT battery charger, actually using the combination of the doublesided LCC and LCC-S compensation circuits, is proposed and implemented in this paper. Finally, an experimental prototype is built to validate the proposed design.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128156725","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}
