Aiming at the problem of medium-high frequency frequency stability in a weak grid connected with self-synchronized voltage source doubly-fed wind turbine, a dynamic state-space model considering both the rotor-side converter (RSC) and the grid-side converter (GSC) was first established. The oscillation mode of the system was studied by eigenvalue-based analysis. For the defect that the eigenvalue-based method is lack of time-frequency resolution capability, the continuous wavelet transform (CWT) is adopted to reveal the oscillation mode of the doubly-fed wind generation system in the time-frequency domain. The dominant oscillation mode is identified online through the relative energy of the wavelet, which is mutually verified by the FFT-based analysis results. Finally, a simulation model of a 2MW doubly-fed wind turbine is built in PSCAD/EMTDC, and the simulation results verified the correctness of the theoretical analysis. The research results provide a reference for fault diagnosis of doubly-fed wind generation systems.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128204547","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 the dc network, the power electronic transformer (PET, also known as solid-state transformer, SST) is the crucial interface device. To achieve better characteristics, the SST based on modular-multilevel-converter (MMC) is proposed. The cascade modulization and high switch efficiency of MMC-SST bring challenges to its electromagnetic (EMT) simulation. The numerous submodules increase the order of the node admittance matrix, requiring more computation resources; the high switch frequency requires a smaller time step, decreasing the calculation speed. To deal with these problems, this paper proposes a parallel EMT simulation method based on the diakoptics. This method achieves parallelized calculation at the system level and submodule level by tearing the whole system into subsystems and applying the compact EMTP method. The proposed method is verified in MATLAB and an FPGA-based real-time simulation platform.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128638634","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}

For the offshore wind farms (OWFs) integrated into the bulk power grid by multi-terminal direct current (MTDC) systems, the challenges for realizing fast frequency control consist of coordination of OWFs with different wind speeds and limited communication condition. Address those challenges, this paper proposes a fast frequency control (FFC) method for MTDC integrated OWFs based on short-term power overshoot. The frequency-DC voltage droop control is used to transmit the frequency deviation signal from the onshore power system to the OWFs without long-distance communication dependency. Then, the FFC is applied to the wind turbine (WT) power control loop, allowing the OWF to respond to frequency fluctuation and further support the onshore power system by use of the rotor kinetic energy according to short-term power overshoot reference. Moreover, the coordination strategy of OWFs with different wind speeds are proposed, which adaptively adjusts the power control coefficients according to real-time rotor speeds. Simulation results show that the proposed method can respond to grid frequency fluctuation in time and can effectively coordinate the OWFs for supporting the grid frequency.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121429375","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}
