In many applications, high voltages will result in high electric fields and high current densities in miniaturized components, which can lead to gate oxide breakdown of circuit components and thermal damage in ICs. Therefore, ESD protection circuits are added inside the electronic product in order to prevent the above damage, but the area of the protection cell should not be too large, otherwise a large proportion of the IC manufacturing cost is spent on the protection circuit. In this paper, we investigate how to improve the ESD protection of the designed high-voltage components through TSMC’s 0. 1S-micron BCD HV process. The sample structures of this work all use high-voltage N-channel laterally diffused MOSFETs (LDMOS), and the I/O protection components can be improved by this protection architecture. First, the ESD robustness of the device is enhanced by embedding a Schottky diode in the bulk end of the nLDMOS. The Schottky diode is parasitized horizontally at the body terminal. Since the parasitic Schottky diode is at the body electrode of the device, the parasitic BJT capability is enhanced, making it easier to trigger the conductivity of the device. Therefore, the new components $mathrm{V}_{mathrm{t}i}$ and $mathrm{V}_{mathrm{h}}$ values decrease (because the horizontal parasitic Schottky is reversed so the decreasing is obvious), so that the high-voltage ESD protection components have a better performance under ESD events, this design also makes the anti-ESD capacity $mathrm{I}_{mathrm{t}2}$ significantly increased. In the case of the body-end horizontal (reversed) embedded Schottky element, the largest $mathrm{I}_{mathrm{t}2}$ is found on the $mathrm{R}mathrm{e}mathrm{f}_{-}8mathrm{S}_{-}mathrm{B}_{-}8$ device, whose $mathrm{I}_{mathrm{t}2}$ improvement rises up to 4. 529A, an significant increase of 244.41% was achieved as compared with the reference sample.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126234110","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}

Orderly power utilization (OPU) is the most efficient means to address severe short-term power shortage so as to avoid cycled blackout events. However, the traditional OPU strategy usually ignores Openness, Equity and Justness (OEJ) principles which may inconvenience many end users (especially big industrial users) and affect satisfaction. Herein, an optimization framework for full cycle OPU is proposed. According to the demand difference in OPU plans in different periods, the optimization model of a full cycle OPU plan with variable intervals is established. Numerical simulation results indicate the great potential of the proposed method to solve power shortage problems by considering the OEJ principles.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130233828","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}

Many methods have been proposed to control WPT systems, such as DC-DC converters, inverters, and the positional relationship between transmitting and receiving coils. However, previous research has assumed that the mutual inductance, which cannot be measured during power transmission, is known. Therefore, this study proposes a control system that considers the variation of mutual inductance during power transmission by estimating the mutual inductance. First, the WPT system is modeled. Next, the mutual inductance estimation is explained and the control system is designed. Finally, the effectiveness of the control is demonstrated through simulations in MATLAB.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127625972","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 digital transition allows connectivity and automatization of several sub-optimal tasks. Nevertheless, most energy distribution systems lack efficient and automated outage management systems that provide alarms and event notifications for different fault types, especially when no power is available to smart meters after a sustained three-phase fault. Most of the time the fault location is defined by customers’ calls. As an alternative, we propose a binary search algorithm for three-phase fault location based on smart meters with radio mesh communication capabilities. A virtual environment is used to evaluate the proposed method. The results show a better performance of the binary search compared with a linear search method without significant location errors. Several challenges were accounted for, such as the hidden terminal problem and the collision of messages when a burst of last gasp signals is transmitted through a wireless link. The proposal validates the feasibility of outage management systems that provide fault locations based on smart meters’ last gaps signals. The solution can be deployed in a similar infrastructure with minor investments in telecommunication apparatus.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114930195","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}

They support the detection and isolation of problems in the power system, so that the operation of unaffected parts can be maintained. ElectroMechanical Relays (EMRs) are still predominant around the globe in the high and extra high voltage transmission systems. Thus, ensuring the reliability and traceability of relays is of major importance. One way to achieve this is through parallel redundancy by implementing redundant sensor architectures, such as one-out-of-two (1oo2). In this paper, we propose a novel algorithm for the fault prognosis-i.e., detection and failure date prediction – and isolation prediction for redundant 1002 architectures. The algorithm predicts the failure ahead of time and provides an estimated date for the failure event. Our contribution in this work is on the fault isolation prediction, where we infer-ahead of time, before the occurrence of the fault-which relay of the pair will cause the failure. The fault isolation is achieved by means of Machine Learning (ML) based feature extraction and binary classification methods. We apply the algorithm on EMRs based solely on the discrepancy time signals of the opening and closing events of the relays. The algorithm has been tested on data from redundant EMRs from the publicly available SOReDD dataset. While relays are binary switches, our work could potentially not only be applied to other types of binary switches but also to binary sensors as they also produce a binary output signal.","PeriodicalId":364883,"journal":{"name":"2023 13th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117194760","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}

Therefore, a novel voltage optimization model of distribution networks with various distributed PV inverter control technologies is proposed in this paper. Firstly, the voltage optimization model for distribution networks with various distributed PV inverters is introduced, and different equality and inequality constraints for both grid-following and grid-forming inverter control technologies are modeled in detail. Then the nonlinear interior point method is used to solve the optimization model.

So, this paper investigates the impacts of wind power-based DG installed on the distribution system in Thailand using PSCAD software. The case study system is modeled after part of the Provincial Electricity Authority (PEA) distribution network in Northern Thailand. The comparative study with the case without DG has also been done on various parameters such as type of faults, location, and number of DG.
