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.

Harmonic mitigation has received much attention recently, and harmonic contribution evaluation is an important prerequisite. This paper proposes a harmonic source localization method based on critical admittance screening with the adjusted coefficient of determination, in order to determine whether the main contribution to PCC's harmonic voltage distortions is upstream or downstream. The data screening method is based on adjusted coefficients of determination according to the voltage and current data measured at the point of common coupling (PCC). Harmonic source localization is performed with critical admittance. Compared with the traditional harmonic source localization method, data segments with a high degree of linearity in the harmonic voltage and current of the PCC are selected based on the adjusted coefficients of determination. The effect of fluctuations in the background harmonic of the novel power system on the critical admittance is effectively circumvented, which improves the estimation accuracy of the harmonic admittance. In order to verify the performance of the proposed method, several scenarios with different properties of harmonic admittance have been designed in MATLAB. The verification demonstrates the validity and accuracy of the proposed method.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"290 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":"115214321","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}

Virtual synchronous generator (VSG) is a control strategy that simulates the rotor motion and provides voltage and frequency support for power system. Although virtual synchronous generator can solve the low inertia and weak damping problem caused by high permeability of renewable energy, the influence of harmonic dynamic characteristics on VSG can not be ignored. In order to study the harmonic dynamic characteristics of virtual synchronous generator, it is necessary to establish a model to describe the multi-frequency dynamic characteristics. Based on the theory of harmonic state space (HSS), a small signal model of virtual synchronous generator is established in dq frame.
