With the large-scale integration of power electronic devices and the continuous increase in the number of harmonic sources, this configuration method has encountered problems such as high cost and low efficiency. Therefore, this article proposes an APF optimization configuration strategy based on the concept of partition governance. Firstly, the harmonic sensitivity and harmonic coupling indicators that characterize the interrelationships between nodes were provided, and based on these indicators, the microgrid was partitioned and the connection location of harmonic control equipment was determined. Secondly, the objective function is constructed with the goal of minimizing the investment cost, with the governance results meeting national standards as constraints, and solved using Particle Swarm Optimization (PSO) algorithm. Finally, an IEEE33 node system was analyzed as an example, and the calculation results verified the effectiveness and economy of the proposed optimization configuration strategy.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"12 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":"132494822","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}

However, the wideband oscillation issues have become increasingly serious due to the interaction of PMSG-based WTGs and the grid. It is generally considered that the interaction characteristics almost completely depend on the grid-side subsystem (GSS), so that the machine-side subsystem dynamics (MSSD) are usually ignored in existing researches. The rationality of such simplification method has not been systematically studied. Therefore, the comparative study of coupling characteristics between machine- and grid-side subsystems of PMSG-based WTGs under four types of control modes is carried out in this paper. Firstly, the detailed impedance models of PMSG-based WTGs under these control modes are developed and validated. Based on these impedance models, the comparative analysis of coupling characteristics is carried out qualitatively and quantitatively. Some useful findings are obtained. Finally, the case study verifies the impact of such coupling effects on the stability analysis of gird-connected PMSG-based WTGs.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"202 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":"134444990","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}

Multiple GFM converters connected to the same point of common coupling (PCC) should not only ensure harmonic current sharing, but also reduce the PCC voltage harmonics. Most of the existing solutions need to extract and control each harmonic sequence separately, resulting in enormous calculation. To solve this problem, a harmonic control method for GFM converters based on unified harmonic voltage-current droop is proposed. By establishing a unified droop relation between all harmonic components of PCC voltage and output current, we achieve to share harmonic current according to converter capacity while reducing PCC voltage harmonics. The proposed method is applicable to both grid-connected and islanded modes, and does not need to extract harmonic sequences separately. Compared with existing control methods, it requires less computation, thus easy to be implemented in embedded controllers. Finally, the effectiveness of the proposed control scheme is verified by simulation in the MATLAB environment.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"384 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":"122873451","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 ET-MPC inherits the characteristics of fast dynamic response and multi-objective optimization of MPC. Additionally, the method detects the system data and calculates state errors in real time. Only when the state error exceeds the preset threshold will the MPC scheme be triggered to update the control signal. Otherwise, the MPC scheme is paused and the control signal remains unchanged. Therefore, compared with the FCS-MPC method, the ET-MPC method has lower calculation burden, less switching action and less switching loss, while maintaining the excellent dynamic performance of traditional MPC method. Therefore, the ET-MPC is perfectly suited for the CSM SIMO converter. The simulation results verify the effectiveness of the proposed method.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"39 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":"115982782","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}

However, there are also drawbacks to SUPWM that come to light. When the conventional SUPWM is employed in the MMC, the discontinuous switching action of the three-phase submodules will result in a large common-mode voltage on the AC side of the MMC. The common-mode voltage can produce serious electromagnetic interference. In addition, in the field of AC drive applications, the common-mode voltage can also damage the insulation of the motor windings and increase the mechanical wear of the bearings. Therefore, the common-mode voltage in SUPWM should not be neglected. To solve the problem, a phase-shifting control method is proposed. The proposed method can eliminate the common-mode voltage generated by SUPWM by changing the phase of the triangular carriers. The effectiveness of the proposed method is verified by Matlab/Simulink simulation.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"20 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":"116091810","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}
