Firstly, this paper analyzes the historical data and uses Copula theory to establish the joint probability distribution of wind power error and forecast power, then obtains the conditional probability distribution of error under certain forecast power. Secondly, this paper decouples the AC/DC hybrid distribution network into AC subnetwork and DC subnetwork, and takes the minimum comprehensive operating cost of each as the optimization goal, among which the carbon trading mechanism is introduced in the AC subnet optimization, and the distributed optimization model of AC-DC distribution network is established. Thirdly, in view of the uncertainty of wind power, an ambiguous set based on KL divergence is constructed. This paper takes the aforementioned error probability distribution as a reference distribution, and the proposed model is converted into a single-layer linear optimization target by using Lagrange dualism theory, and then the distributed solution is performed by using the alternating direction multiplier method. Simulation experiments are carried out on the modified 33-nodes AC/DC distribution network system model, and the results show that the proposed model can effectively reduce the carbon emissions on the distribution network side and significantly improve the consumption capacity of wind power.","PeriodicalId":143306,"journal":{"name":"2022 IEEE 3rd China International Youth Conference on Electrical Engineering (CIYCEE)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124265379","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}

Also due to the controllability of its muzzle velocity and the extremely high responsiveness of whole system, electromagnetic launch technology is considered as another novel way to achieve tokamak device disruption mitigation. Our team has designed a new generation of electromagnetic pellet injection system(EMI). It is able to achieve high-speed injection of the pellet and soft recycle of the armature by using deceleration electromagnetic force. In this paper, the deceleration performance of the C-shaped armature during the deceleration process is analyzed through simulations. The simulation results show that the electromagnetic force of the C-shaped armature's tail during deceleration causes the contact performance between the armature and the rail to deteriorate, and also the armature muzzle velocity cannot meet the requirements of soft recycle. The results of the launch experiments with different decelerated current amplitudes further veriFy the correctness of the simulation analysis and provide ideas for the next design of armatures suitable for EMI.","PeriodicalId":143306,"journal":{"name":"2022 IEEE 3rd China International Youth Conference on Electrical Engineering (CIYCEE)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117203456","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}

A hybrid feature selection algorithm combining MLP and PSO is proposed to reduce the number of input measurements.

We introduce a momentum encoder to select hard triplet samples, which solves the problem of easy gradient dissipation when triplet samples are selected randomly.

The errors induced by the operation of the monitoring device and the parameters of the measured accelerator during the measurement were also investigated. The simulation results show that the thicker the upper plate, the larger the observable energy range, and increasing the sidewall height increases the measured energy range even more. The error caused by the energy divergence of the Gaussian distribution is less than 2.5%. The measurement results can only represent the placement height within ±5 cm. The placement position cannot deviate from the center position ±5 cm.

In this paper, we built a bilevel scheduling model, the upper-level model aims for maximum profit of pumped hydro storage (PHS) and the lower-level model is the market clearing process. We use the KKT conditions to transform the bilevel model into a single-level model. Then, the objective function is linearized by the strong duality condition, and the equations of the KKT conditions are linearized by the big M method. The original bilevel model is finally transformed into a single-level mixed integer linear problem and can be solved by commercial solver such as CPLEX. The results show that the PHS would get the maximum profit when it bids at the locational marginal price (LMP) for both charging and discharging.","PeriodicalId":143306,"journal":{"name":"2022 IEEE 3rd China International Youth Conference on Electrical Engineering (CIYCEE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130499090","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}

Firstly, EV dispatchable capacity is evaluated based on controllability of EVs, and then the multi-objective optimization algorithm NSGA-II is used to solve the optimization model, and the grid dispatching instruction is decomposed into EV subgroup dispatching instruction.

Three CP-IPMV machine topologies with different PM structures are comparatively analyzed, including V-shaped PMs, U-shaped PMs, and spoke-array PMs with alternating flux bridges. To make a comprehensive comparison, a synthesis analytical model based on a magneto motive force (MMF)-permeance function is proposed to analyze the relationships of electromagnetic performance with key design parameters. The effect of a biased pole arc is also considered in the analytical model. Besides, influences of pole ratio, pole arc, PM dimensions, and slot opening ratio on torque performance are studied by finite element analysis (FEA). Moreover, to investigate the superiority of the CP-IPMV machine, three CP-IPMV machines with different PM types are compared to a regular IPM machine in terms of back-EMF, torque performance, power factor, etc. It is proved that the CP-IPMV machine exhibits high torque density, low torque ripple, high power factor, and flux-weakening capability, especially the CP-IPMV machine with VPM type.
