In this paper, a novel two-layer coordinated control for individual and networked Ad-hoc microgrids is proposed. The first layer deals with the internal coordination between RE and ESS to maintain a stable operation within an Ad-hoc microgrid by using bus frequency, thereby without communication links to reduce power consumption. When forming the networked Ad-hoc microgrids to a critical load with higher load demand, the regulations on the bus frequency from each Ad-hoc microgrid will result in instability. Therefore, a quasi-SoC balancing control strategy for the networked Ad-hoc microgrids is further proposed with only binary information exchanges to mitigate the interactions caused by the internal coordination control among the Ad-hoc microgrids. To verify the effectiveness of the proposed control approach, simulation results with Matlab/Simulink are presented.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"7 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":"123824979","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, when the DAB input and output voltages do not match the transformer ratio, the inductor current stress will increase, which affects the operating reliability. In order to optimize the current stress of DAB converter in wide input voltage range condition, this paper firstly proposes a DAB converter with voltage adjustment unit (VAU-DAB). The mathematical model of DAB converter is deduced to analyze the inductor current stress characteristics when the input and output voltages are mismatched. Then, the VAU and its control algorithm are introduced. VAU can adjust the input voltage in real-time, which ensure both side voltages of DAB are matched in wide input voltage range. The proposed system can optimize the current stress and improve the robustness of DAB. Finally, simulation results verify the effectiveness of the proposed VAU-DAB topology and control 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":"128511259","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 order to meet economy and green, a multi-objective planning method based on transmission and distribution coordination is proposed. The model objectives are to minimize the total cost of investment and operation, to minimize the curtailment rate of new energy, and to minimize the carbon emission of transmission and distribution networks. AC power flow is used to account for node power balance, unit output and ramp-up constraints, N-1 constraint and so on under temporal scenarios. The decomposition optimization modeling idea is adopted so as to decompose the model into a transmission network planning sub-problem and multiple distribution network planning sub-problems. The model is solved effectively by NSGA-III embedded with ATC algorithm. Finally, the optimal solution set and the optimal compromise result are given by case study, which verifies the equilibrium and effectiveness of the method.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"14 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120983956","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 initial LS-SVR model is trained on the offline data set, and then applied online on other data sets with the same experimental conditions. In the process of online application, the model will be updated online every certain cycle.

Thus, the power-electronics-based electric machine emulator is introduced, where the terminal voltage of the driving converter is sensed for current reference generation of the emulator. However, in this conventional control structure, the stability and accuracy of the machine emulator is compromised due to the low-pass filter during the voltage sensing process. In this paper, the low-pass filter during the voltage sensing process is removed. The terminal voltage of the driving converter is reconstructed by the sampled current, and the current reference for the emulator is reconstructed by the modulation signal of the emulating converter, achieving better performance and stability.
