First, under the spatial correlation rules, the power supply area within the surface rainfall boundary is judged by multidimensional data, such as digital geography. Secondly, with the distribution transformer of the power supply area as the geometric center, the area and the scale of power outage users are solved. Thirdly, the supervised learning algorithm is used to predict the disaster area out of service, on the basis of the binary classification of prior data. Finally, the dynamic changes of the predicted results are calculated according to the intensity changes of the rainfall process. Using the confusion matrix and the receiver operation characteristic curve to verify the prediction method. The numerical results show that this approach can dynamically predict the power supply area interrupted by heavy rainfall, which can be used for the production command in the process of “water rise and power failure, water back and power recovery”.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124720346","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}

To ensure the system frequency stability, this paper proposes to enhance the PFR capability of TPPs through integrating energy storage systems (ESSs) into them. By applying the PFR control strategy to the ESS, the fast response capability of the ESS is utilized, and the overall response speed of the power plant integrated with an ESS can be significantly improved. Furthermore, the state of charge (SOC) of the ESS is kept within the permissible range during the operation by adopting an energy recovery strategy to restore the released energy for PFR periodically. The effectiveness of the proposed control strategy is verified by simulation results.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125008518","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}

To find the reason of discharge, an electric circuit model was established to analyze the current distribution of contact points inside the Ground Wire-Suspension Clamp System (GW-SC System). Subsequently, the current waveform flowing through each contact point in different torque was obtained through finite element simulation. Based on the result, a single contact point model was created to analyze the electric field intensity distribution around the contact point with the highest current flow. The final result shows that, under the action of lightning current, the air gap near the contact point has a very high electric field intensity, which may even exceed 30kV/cm. The shape and size of contact point have a great impact on the electric field intensity and distribution.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121033706","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 interface of composite cross-arms, on the other hand, might be faulty owing to its variables and external environmental influence. Existing detection technologies have several limitations, and active infrared thermography, as a new technology, has demonstrated its efficacy in identifying faults in composite materials. In this work, the thermal response characteristics of composite cross-stretcher interface flaws are comprehensively investigated using the finite element simulation method. The thermal response characteristics of interface defects of various sizes, depths, and kinds are compared, and the temperature variation characteristics of the defects are described using linear and logarithmic coordinates. The nature of the defect can be extracted from the rate of temperature change and the temperature in the smooth phase in linear coordinates, and the nature of the defect can be extracted from the curve shift time, magnitude, and direction in logarithmic coordinates. The research presented in this work demonstrates that active infrared thermography can effectively distinguish interface defects in composite cross-arms.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123935825","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 way, a regular hydroelectric power plant was transformed into a double pumped hydroelectric power plant. The proposed system consists of 4 stages for the coupling of the double pumping system in regions of the Peruvian highlands. In the first stage, the drought period was evaluated based on historical hydrometeorological data from the Malpaso station. In the second stage, the activation of the system was validated, verifying whether the daily energy produced by the hydroelectric plant is lower than usual and confirming that the region has periods of low water demand. In the third stage, the energy generated by the solar panels was redirected during the night. In the fourth stage, the hydraulic pumps located in the lower reservoir were activated to bring water to the upper reservoir thanks to the photovoltaic energy generated, increasing the water resource in the upper reservoir. The proposed system design will provide an alternative to maintain stable flows of electricity production, even if the generation area has a deficit of water resources due to low rainfall.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126531739","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}

Then, construct a dilated convolutional network model based on the attention mechanism, combine it with the softmax classifier, and train the network model. Finally, the effectiveness of the proposed method is verified by comparison of simulation and experiment.

However, frequent operations of the OLTC are detrimental to its long-term service life. Also, discrete adjustments of OLTC taps cannot meet the requirement of precise volt/var control (VVC). To address this, the emerging electric spring is proposed for joint VVC with the OLTC in ADNs in this paper. First, we develop a time-series optimization model for VVC in ADN. In this model, multiple electric springs and the OLTC are regarded as controllable devices. The objective function comprises minimum power losses and minimum voltage violations. Then, the electric springs contribute to decreasing total tap movements of OLTC, which is represented as a constraint in the proposed model. Case studies are carried out on a modified IEEE-33 test feeder. Simulation results validate the effectiveness and accuracy of the proposed model.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131328656","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}
