As the number of engineering projects contracted is increasing, the possibility of making mistakes by contractors is increasing as well. In this way, the punishment for the contractor which contracts more engineering projects will be more. To solve the problem, this paper presents an evaluation method based on data-analysis. Firstly, we calculate the penalty score of projects in turn and set the target of the total penalty score. Secondly, we calculate the penalty score of projects after considering the coefficients of them, and we calculate the objective function. And then, the best coefficient of the penalty system is calculated by hyper-parameter algorithm. Finally, the best coefficients of the penalty system and the function that can be fitted by the set of the best coefficients. The results show that the proposed method is available to solve the problem and make the evaluation for the penalty system of distribution network engineering contractors objectively.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120973838","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}

Its submodule capacitor needs to bear the impact of huge bridge arm current and has the highest failure rate in the system. ESR (equivalent series resistance, ESR) value and capacitance value, as important parameters reflecting capacitor health, play a significant role in aspects such as capacitor efficiency evaluation, predictive protection and so on. Based on the M3C converter model, this paper raises an online monitoring method of ESR value on the account of changing characteristics of switch signals of M3C submodule and capacitance value using Kalman filter. Finally, through PSCAD/EMTDC simulation platform, the 59 level M3C converter model is simulated, and the simulation data shows the practicability of the online monitoring method.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128135168","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}

Hence, a comprehensive assessment system and method of DNEP is proposed. The comprehensive assessment system of DNEP is established and two different evaluation indexes are set: macro assessment index set and micro assessment index set. Meanwhile, a combined weight hierarchical calculation model based on DEMATEL-ANP-anti-entropy weight method and improved gray correlation analysis is proposed, which can calculate the weights of macro assessment indexes and micro assessment indexes separately. The model is used to make the comprehensive assessment system subjectivity and objectivity simultaneously.

In this paper, based on the power balance of the AC/DC hybrid microgrid interface, the coupling relationship between the AC frequency and the DC voltage is derived, and the influence of the coupling coefficient on the transient and steady-state performance of the system is analyzed. On this basis, the coupling coefficient is adaptively changed, the overshoot of the AC frequency is reduced, the system's inertia is increased, and the system's dynamic performance is improved.

To address this problem, a novel deep learning model embedded with self-attention layers is firstly proposed for TSA. After that, a transfer learning strategy is further proposed to develop a set of predictors aiming at the identification of unstable generators. Case study on the New England to-machine 39-bus system shows that, compared with other baseline models, the proposed self-attention-embedded model is able to achieve better performance in transient stability classification. Moreover, together with the embedded attention module, the predictors generated by transfer learning can be used to inform the operators about the cluster of the unstable generators in the disturbed power system.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"6 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133526524","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}

Through in-depth analysis of the mechanism of return power generation, the mathematics model of power of DAB converter is built. The model prediction equation of output voltage of DAB converter is obtained by state space averaging method, and the return power is suppressed by Lagrange multiplier method. Finally, the circuit model is built to verify the analysis conclusion, and these results are compared with those of the traditional SPS modulation and EPS modulation. The results demonstrate that this method can significantly inhibit the return power of the DAB converter, and can effectively improve its output properties.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133717647","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}
