By theoretical analysis and experimental verification, it is proved that AUI type coupling mechanism has the characteristics of high coupling performance, high power density and high anti offset ability compared with the traditional E-type coupling mechanism.

The traditional MF methods follow the post-outage recovery criteria, which sectionalize the on-outage DS into multiple microgrids after the faults occur. However, if there is much power exchange between the DS and the microgrid, it will lead to fail for such recovery-oriented MF methods, reducing the capabilities of resilient DSs in resisting and rapidly recovering from an extreme condition. To further enhancing the resilience and risk-resistant performance of DSs in extreme conditions, this paper proposes a proactive networked MF method to restrict the regional power exchange prior to the extreme events and ensure the microgrids can be safely formed when the faults actually occur. Firstly, the photovoltaic (PV) parameters are obtained by using Monte Carlo method. Next, the active power output of the micro gas turbine (MT) and the energy storage system (ESS) is optimized to reduce the network losses. Moreover, power exchange between the microgrid and the other part of DS is constrained. The artificial bee colony (ABC) algorithm is utilized to solve the proposed model. Such MF strategy can effectively protect essential loads by optimally determining the lines to be cut. The effectiveness of the proposed method is validated with the modified IEEE 33-node distribution test system.","PeriodicalId":416229,"journal":{"name":"2022 IEEE 5th International Electrical and Energy Conference (CIEEC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122766238","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}

Though great progress has been made in this field, these existing methods cannot consider the variation characteristic of wind power well. To tackle this problem, this paper decomposes the historical data of wind farms into state components and variations, where state components of wind power output are used to train WGAN-GP. Through the game training of WGAN-GP, the generative model can establish the mapping between noise distribution and wind power state component set. Then, variations are sampled from the corresponding t location-scale distribution and later added to the state component to generate scenarios of wind power. The simulation results show that the generated data by the proposed model closest imitates the probability distribution of historical data.","PeriodicalId":416229,"journal":{"name":"2022 IEEE 5th International Electrical and Energy Conference (CIEEC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114466567","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}

Due to the special core magnetic valve structure and AC/DC co-excitation working mode, the vibration and noise problem of MCR is serious, which has become the main factor restricting the development of MCR. This article establishes the three-dimensional core magnetic field-mechanical coupling model based on the distribution of finite element software. For the centralized magnetic valve structure, the magnetic field and vibration displacement of iron core under different DC control current are numerically calculated. Besides, the vibration acceleration and noise of MCR surface under different loads are also measured and the frequency spectrum of vibration and noise signals are analyzed. According to the simulation results, the magnetic flux density at the magnetic valve is significantly higher than other parts. The value of displacement around the magnetic valve area and “T-type” contact surface are larger. The sound pressure of MCR is higher under load 18600kvar condition and the low frequency harmonic component of time domain waveform increases. The results can provide calculation method and experimental data for the analysis of the vibration characteristics of MCR.","PeriodicalId":416229,"journal":{"name":"2022 IEEE 5th International Electrical and Energy Conference (CIEEC)","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128329507","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 this paper, a remedial method based on FOC for five-phase permanent magnet synchronous motor (FPMSM) with sinusoidal back electromotive force (EMF) is proposed to suppress the current distortion and torque ripple under single phase open-circuit fault (OCF). For FPMSM with sinusoidal back EMF, the circular trajectory of current in the stationary $alpha-beta$ frame can produce circular rotating magnetomotive force to output constant torque. After single phase OCF, the motor model based on VSD keeps unchanged because the prefault normal matrix is adopted in the decoupling transformation. However, the modulation voltages of the inverter are no longer equal to the phase voltages of the motor, resulting in current distortion and torque fluctuation. By analyzing the inverter model and motor model under single phase OCF, a remedial method is proposed, which the disturbances are suppressed by reconstructing the voltage transformation matrix and using voltage feedforward. Compared with conventional methods based on PR or double PI controllers, the structures of current controllers are no need to be changed, so this method has the advantages of simple application and avoiding complex parameter design. The simulation verifies the effectiveness of the proposed method.","PeriodicalId":416229,"journal":{"name":"2022 IEEE 5th International Electrical and Energy Conference (CIEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130320936","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}
