Moreover, the penetration of EVs into power systems not only can reduce energy loss and lessen emission, but also can provide ancillary services for improving power quality, shaving peak load, etc. Given this background, according to key technology and demonstration engineering of many countries, such as USA, Japans and Europe, the status of EVs’ research and promotion at home and abroad were analyzed in detail. Then, the three kinds of EVs applied widely at present were respectively presented to identify their advantages and disadvantages as well as the concept of V2G. Given this background, a mathematical model for optimizing discharging strategy in EV charging stations is developed and solved by particle swarm optimization (PSO) with the maximization of the total operating income of the EV charging stations as the objective function, and some operating limitations as constraints to be respected. Finally, IEEE 34 node test feeder is applied to illustrate the feasibility and effectiveness of the developed model.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129880132","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 article introduces a set of methods for judging the aging degree of silicone rubber composite insulators on site, including our handheld compact and low-cost hyperspectral camera and classification algorithm. The hyperspectral camera has the advantages of compactness, stable working performance, and Broad spectral detection range (400nm-1000nm). After connecting the hyperspectral camera to the smart mobile terminal,We also through the APP we developed, which completes the visualization of spectral data, can display the real-time spectral of the silicone rubber composite insulator sample on the screen of the smart terminal. In addition, we build a composite insulator aging prediction model based on the three algorithms of SVM(support vector machines), KNN(K-NearestNeighbor) and decision tree. The results show that the SVM model has the best effect. And the prediction accuracy of this model is 96.09%. it means that the model has high feasibility for predicting the aging degree of composite insulators.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128284992","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 the industrial visual recognition and early warning system, it is difficult to achieve accurate and real-time tracking. In this study, we propose a real-time target tracking algorithm based on improved SiamFC. The second convolution layer in the original siamese network structure is replaced by deeply separable convolution, improves the tracking speed by reducing parameter calculation, meet the need of real-time tracking in practical application. In the third convolution layer, mixed deep convolution is used to extract features through convolution kernels of different dimensions to achieve multi-feature fusion, extract features with stronger robustness, and improve the network's ability to distinguish objects and backgrounds. The performance of the algorithm is tested on OTB2015 data set and power construction site surveillance video. Experimental results show that compared with the SiamFC algorithm, the algorithm has a certain improvement in the tracking success rate, tracking accuracy and tracking speed, and can meet the tracking requirements in power construction scenarios.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129695099","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}

For a day-ahead optimization problem of IES, a coordinated optimization model is established considering the dynamic characteristics (DC) and the integrated demand response (IDR) in this study. Firstly, the DC of gas and heating networks are modeled and analyzed, and their energy storage capacities are explored. In addition, this study combines price guidance and incentive measures to fully tap the user-side demand response capabilities and establishes the IDR model and energy system model. Finally, an optimal dispatching model of the IES considering the DC and IDR is shown, and the incremental piecewise linearization method is used for linearizing the model.

Scholars have performed many studies on the fault characteristics of the voltage source converter (VSC) on the AC system, whose IGBT is immediately blocked after the bipolar short-circuit fault occurs. However, there are few researches on the photovoltaic(PV) system output modeling of bipolar short-circuit fault. This article presents a PV system output analysis model, focusing on the metallic bipolar short-circuit fault for DC microgrids. Firstly, according to the diodes feeding progress of the DC/DC converter on the PV side, the whole metallic bipolar short-circuit fault process is divided in detail. Then, accurate state equations are established by the equivalent circuits of different transient stages. PV source output characteristic is expressed piecewise linearly, and the expressions of each electrical fault variation are provided. Finally, a simulation model is constructed using MATLAB/Simulink software. The effectiveness of proposed model is validated with simulation results, showing that its high accuracy for different fault locations, illumination strength, ambient temperatures and fault resistances.","PeriodicalId":216155,"journal":{"name":"2021 International Conference on Power System Technology (POWERCON)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127008616","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}
