So in this paper, considering the characteristic of high-frequency coupling caused by the sideband effect of the sinusoidal pulse width modulation (SPWM) modulator, a complex transfer function of the SPWM modulator is first derived, which can clearly reflect the dynamic coupling between disturbance frequency components and sideband frequency components. Then, a comprehensive multi-frequency impedance model of the three-phase LCL-type grid-connected inverter under the dq-frame is established. Based on the proposed model and the generalized Nyquist criterion, the high-frequency oscillation phenomenon of the grid-connected system under the weak grid is analyzed, and the frequencies of the resulting oscillation components are predicted. To verify the accuracy of the proposed model and the validity of the theoretical analysis, the corresponding simulations under different conditions are carried out.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127435302","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}

Furthermore, the state variables of multiple energy conversion units are needed to detailed model in the energy flow algorithm process. To cope with that, a unified energy flow algorithm is proposed in this paper, considering the influence of coupled units on energy flow calculation in IEGS. Firstly, the multi-energy conversion units are abstracted as a energy hub (EH), which provides a unified modeling method to describe the energy flow relationship between different energy networks. Secondly, the electric and gas inputs of EH are added to form a new state variable column vector based the original sub-network state variables. Then, a new Jacobian matrix is derived based on Newton-Raphson method to form an iterative relationship. Finally, case study is verified on the modified IEEE39-NGS20 test system. The proposed energy flow algorithm can effectively reduce computational burden in multi-energy networks.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124958632","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}

An analysis method of the influence of the control parameters of the VSG controlled ESS on the primary frequency modulation is proposed in this paper. The VSG control scheme of the ESS is briefly introduced and then the exact differential equation for the primary frequency modulation of the power system is established. By solving this differential equation, the complete frequency response curve in the primary frequency modulation process of the power system is obtained. Therefore, it is possible to further analyze the influence of different control parameters on the frequency response during a frequency modulation process. Moreover, when the State of Charge (SOC) of the ESS reaches the limit during charging and discharging, it will cause a secondary change in frequency. This phenomenon is also analyzed and the corresponding solutions is given.

This makes the converter commutation failure difficult to avoid, which may accelerate deterioration or even destroy the stability of the AC and DC systems. Recently, a novel security measure with additional large-capacity synchronous condenser (SC) has been proposed and installed in the AC support systems of multi-infeed Ultra-HVDC to ensure AC systems voltage stability and prevent commutation failures. This paper deduces the mechanism of SC to suppress commutation failure, compares and analyzes the advantages of SC compared with other reactive power compensation devices as well. According to the characteristics of multi-outfeed and multi-infeed Ultra-HVDC system, the electromagnetic model considering AC grid structure is constructed, and the role of SC in practical application system is simulated and tested.
