The energy hybrid energy storage system smoothes its power fluctuations, thereby stabilizing the DC bus voltage. Among various energy storage methods, Superconductor Magnetic Energy Storage (SMES) can store electrical energy in a long-term, high-efficiency, and non-destructive manner. It has the advantages of fast response, high power density, and high efficiency. The system can respond to different power response demands in the DC microgrid, and improve the utilization rate of renewable energy and the stability of the microgrid. A layered control strategy of bus voltage based on a DC microgrid is proposed, and the state of charge (SOC) of the energy storage unit controls the switching of the energy storage unit between different operating modes. The simulation platform was built by MATLAB/Simulink, and the effectiveness of the proposed control strategy was verified.","PeriodicalId":227496,"journal":{"name":"2022 3rd International Conference on Advanced Electrical and Energy Systems (AEES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116950432","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}

Distributed and coordinated optimized management of harmonics by multiple APFs in the distribution network is realized. Finally, three APFs with different rated capacities are configured on the established 10-node distribution line model to coordinate harmonic compensation.

It is considered to be an important trend for efficient and clean utilization of diesel. In this paper, the ASPEN PLUS simulation platform is used to establish the whole process model of SOFC system based on diesel reforming, and the effects of SOFC operating parameters such as operating temperature, operating pressure, air excess coefficient and water to carbon ratio on the performance of system are studied in detail. The results show that higher SOFC operating temperature and pressure are helpful to improve the performance of system; With the increase of air excess coefficient from 2.3 to 14.2, the output power of the system is increasing, and the power generation efficiency of the system is decreasing; With the increase of feed water to carbon ratio from 1 to 10, the power generation efficiency and output power of the system increase first and then decrease.

Firstly, the influence of frequency regulation on the torque of the drive train is analyzed. Then an additional damping control method is proposed, and the influence of the control parameters on the control effect is analyzed.

In order to accurately assess the impact of wake, and ensure the safe and efficient operation of wind turbines. In this research, the wake characteristics of NREL 5 MW wind turbines operating under neutral atmospheric boundary are studied by the method of large eddy simulation coupled with actuator line model. The results show that the actuator line model with tower and nacelle can solve the problem of insufficient velocity deficit to some extent. At the same time, the existence of the tower breaks the symmetry of the velocity distribution in the vertical plane, making the velocity distribution below the hub more reasonable. The nacelle and tower vortex also change the turbulence kinetic energy and vorticity distribution. As the wake develops, the wake of nacelle and tower interacts with the tip vortices, promoting wake recovery.","PeriodicalId":227496,"journal":{"name":"2022 3rd International Conference on Advanced Electrical and Energy Systems (AEES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123756142","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}

Aiming at the switch sliding situation of the on-load tap-changer, this work studies the arc temperature distribution characteristics under different contact gap distances, different arc currents and different sliding speeds through finite element simulation. The research shows that with the increase of the gap distance, the contact area between arc and surrounding environment increases, the heat transfer of arc increases, and the distribution range of arc temperature expands. With the increase of arc current, the maximum temperature of arc also increases, and the radius of arc column increases until the arc breaks. The higher the sliding speed, the lower the arc temperature due to the cooling effect of insulating oil.
