For this purpose, the behavior of the EAF current harmonics is examined in statistical terms using the field data collected at a transformer substation supplying an EAF plant. Then, a significantly larger amount of EAF current data is generated using the statistics mimicking the real EAF behavior to train the DL-based harmonic estimator. The outcomes of the research work presented in this paper are two-fold: (i) DL-based method is used to extract phase and amplitude information of the harmonics of the EAF currents using the waveform directly, without computing any time- or frequency-domain features during the estimation process, which helps reduce the processing time , (ii) EAF current data with realistic amounts of time-varying harmonics based on the statistics obtained from a tap-to-tap time of the EAF currents is generated, hence a detailed statistical analysis of the EAF current spectrum is achieved. The method proposed can be used to eliminate the uncharacteristic harmonics of the EAF currents, since it can provide fast and accurate phase and amplitude estimates of the harmonics, serving the need for active power filters in the electricity system.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115075915","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 B-H loop of the amorphous alloy core used in the SAACFCL is very narrow compared to convensional sheet steel iron cores which are commonly used for fault current limiter (FCL). This narrow B-H loop characteristics of amorphous alloy indicates that it cause low core losses and it will require small dc excitation current compared to sheet steel core. Under steady-state grid condition, this proposed SAACFCL behaves as an air core FCL, hence, imposes low impedance and has very negligible effect on the grid operation. However, during a deep voltage sag caused by large fault currents, the core of the SAACFCL desaturates and its ac impedance is increased which limit the fault currents and improve LVRT capability of DGs. The performance of the SAACFCL in improving the LVRT capability of DGs has been validated using a doubly-fed induction generator (DFIG) based wind energy system equipped with the proposed SAACFCL. This system has been simulated using MATLAB/Simulink simulation software. The simulation results with and without the SAACFCL show that the SAACFCL is capable to achieve the LVRT successfully and can meet the grid code requirement. The performance of the SAACFCL in limiting fault current and improving the LVRT has also been compared with that of the superconducting FCL (SFCL). The SAACFCL promises better performances than SFCL.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115810665","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}

When the grid parameters violate the defined limits, the system seamlessly transfers to an islanded operation. In case the PV power surpasses the load demand, the battery absorbs the remaining power, thereby ensuring optimal utilization of the PV power. On recovery of normal grid, the system is capable of seamlessly resynchronizing to the grid. In grid connected operation, the grid provides the power if the PV power is deficient, and absorbs power, if the PV power is in excess. The system further incorporates the benefits of an active shunt filter, thereby enhancing the power quality. This system is single stage, and the PV power is directly given to the voltage source converter (VSC). The battery is connected by a bidirectional DC-DC converter (BDDC), which maintains the voltage of the DC link at the reference voltage provided by an incremental conductance technique, to derive optimum PV power.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115299145","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}

GOOSE messages are directly mapped to the Layer 2 Ethernet without network and transport layer headers that provide data encapsulation. The high-status-number attack is a malicious attack on GOOSE messages that allows hackers to completely take over intelligent electronic devices (IEDs) subscribing to GOOSE communications. The status-number parameter of GOOSE messages, stNum is tampered with in these attacks. Given the strict delivery time requirement of 3 ms for GOOSE messaging, it is infeasible to encrypt the GOOSE payload. This work proposes to secure the sensitive stNum parameter of the GOOSE payload using systematically encoded polynomial codes. Exploiting linear codes allows for the security features to be encoded in linear time, in contrast to complex hashing algorithms. At the subscribing IED, the security feature is used to verify that the stNum parameter has not been tampered with during transmission in the insecure medium. The decoding and verification using syndrome computation at the subscriber IED is also accomplished in linear time.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123214387","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}

However, the variable nature of wind power negatively affects power system reliability. Reduction in wind power variability and hence improvement in power system reliability can be achieved through a number of means including aggregating geographically diverse wind, deploying energy storage systems (ESS), and using flexible loads. This paper proposes a new approach for mitigation of wind power variability by utilizing both aggregation and ESS. Although aggregation of geographically diverse wind power leads to reduced variability, the benefits are limited due to several factors, as discussed in this paper. ESS projects, on the other hand, can be significantly expensive. In this context, the proposed approach helps in overcoming the limitations of the individual methods and provides a more cost-effective solution. Composite system reliability assessment is performed using Monte Carlo simulation on the IEEE 14-bus system to demonstrate the efficacy of the proposed method. Results show that the application of the proposed approach helps in reducing the ESS size while improving the system reliability.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"336 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123228775","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 post fault tolerant operation is designed based on a dc bus midpoint clamping approach for open switch faults in rotor side converter (RSC) with minimal hardware requirements (2-anti-parallel IGBTs per phase). A detailed operational and control strategy is studied with respect to its hardware limitations. One of the major drawback in designed fault tolerant operation is reduction in RSC output voltage capability due to dc link capacitor voltage limitations. Based on these operational strategies, hydraulic governor of drive is adjusted to deliver power with reduced slip variation of ±5.07%. The existence of dc component and low frequency components in fault tolerant operation causes dc link voltage fluctuation, it leads to output voltage unbalance. To compensate this dc offset value is injected with carrier based pulse-width modulation (CBPWM) to suppress dc link voltage fluctuation.

In this scenario, the paper presents some important issues related to hysteresis current control operation, which affects the converter semiconductor switching pattern and performance in metal industry applications. The paper shows some good features achieved with the digital implementation of a hysteresis current control. Following this line, it is possible to limit the converter switching frequency and semiconductor stress and reduce the spectral harmonic spreading by digital hysteresis current control when the control system works with low sampling rates. Therefore, by an adequate choice of the sampling rate, the control system can be designed to respect and/or limit stress and losses in the power switches. Besides, the design can also lead the converter to low current ripple levels and an optimized size, weight and price of input inductors. The study is conducted through simulation and experiments.
