However, the analytical modeling process of impedance of renewable energy equipment is complex, and the impedance acquisition method based on data measurement has the defects of time-consuming and inconvenience for online measurement. In order to solve the above problems, an impedance identification method based on the joint of knowledge driving and data driving for Doubly-Fed Induction Generator (DFIG) is proposed. First, the small-signal model of DFIG is established based on knowledge-driven, acquiring the variables with nonlinear relationship with sequence impedance. Then, the Extreme Gradient Boosting (XGBoost) model is trained based on data driving to realize the identification of DFIG's sequence impedance under multiple operating conditions. Finally, the experiment on CHIL (Control-hardware-in-loop) is carried out to verify the accuracy of the XGBoost model.","PeriodicalId":185921,"journal":{"name":"2023 IEEE 6th International Electrical and Energy Conference (CIEEC)","volume":"8 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":"128285527","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 dynamic traffic flow in highway traffic network presents the characteristics of multi-temporal distribution and congestion. Dynamic vehicle-flow coupled distribution network has strong randomness, uncertainty and dispersion. Therefore, a method to divide highway energy community based on the density and correlation of highway traffic network and power network is proposed herein. Firstly, the coupling model of highway traffic network and power network is established based on the electric-hydrogen integrated energy supply station. Secondly, the highway energy community is defined, and its measurement index is given based on synergetic theory. Finally, a method of dividing highway energy community structure based on density and correlation is proposed.

The critical current, volume energy density, and loss of the four structures are compared. It is concluded that the three stepped cross-section coil has a significant impact on improving the volume energy storage density. According to the distribution of flux density up and down the magnet and the influence of the charging rate, a new step current injection method is proposed to improve the energy storage density further.

A reactive power optimization model is established in the second level to optimize the short-term (5min) reactive output of each PV plant, aiming at the minimization of nodal voltage deviations. Meanwhile, it also considers the state of charge (SOC) correction of BESSs. In the third level, a model predictive control (MPC) based integer nonlinear programming (INP) model is developed to optimize the tap of the on-load tap changer (OLTC) and the reactive output of capacitor banks (CBs), which aims to cope with the voltage fluctuations caused by the long-term (30min) power changes in loads and PV plants.
