GaN-based vertical power field-effect transistors (FETs) are very promising in various power switching applications because of their high current density and small chip size. In this letter, a novel GaN-based trench gate metal-insulator-semiconductor field-effect transistor (MISFET) featuring an $mathrm{Al}_{0.3} mathrm{Ga}_{0.7} mathrm{~N} / mathrm{GaN} / mathrm{Al}_{mathrm{x}} mathrm{Ga}_{1-mathrm{x}} mathrm{N} / mathrm{n}-$GaN double heterostructure (DH) is proposed and modeled. Instead of using the traditional unstable Mg-doped p-GaN as the vertical channel barrier layer $mathbf{A l}_{x} mathbf{G a}_{1-x} mathbf{N}$ is adopted and proved to be able to form a potential barrier height larger than 3 eV by the negative polarization charges at the $mathrm{GaN} / mathrm{Al}_{mathrm{x}} mathrm{Ga}_{1-mathrm{x}} mathbf{N}$ interface. The proposed device exhibits a high drain current density, a low on-resistance, and an adjustable threshold voltage from 3.4 to $8.9 V$ only by changing the Al content and thickness of the $Al_{x}Ga_{1-x}N$ VCBL.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122897482","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}

While large-scale new energy access meets people’s needs, it also brings many complicated problems. Subsynchronous oscillation of new energy has always been one of the main problems threatening the safe operation of the power grid. The complex torque coefficient method is one of the methods to study the traditional AC power grid. This paper studies the subsynchronization problem of direct drive permanent magnet synchronous generator (PMSG) with large capacity in the near area of thermal power units, and proposes a simplified modeling method for PMSG, which simplifies the full-control device into an equivalent voltage and current source, which greatly simplifies wind-fire bundling Sub-synchronous analysis of the system.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116059149","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 prediction of transformer top oil temperature based on historical data has become an effective way to evaluate the thermal state. To improve the prediction accuracy of top oil temperature of transformers, a new top oil temperature prediction model based on Long Short-Term Memory (LSTM) is proposed in this paper. The strong correlation factors affecting the top oil temperature are determined by the heat map and are selected as the model input. In addition, the concept of sliding time window is introduced, and the optimal time step is determined by particle swarm optimization (PSO) to improve the prediction accuracy of top oil temperature. The test results show that the multi-factor LSTM prediction model with time step optimized by PSO has a higher prediction accuracy.","PeriodicalId":308213,"journal":{"name":"2021 4th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126702731","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}

This paper proposes a mathematical model of the photovoltaic module degrading process. The degrading model bases on Latin hypercube sampling in the Monte Carlo simulation, using photovoltaic cells I-V characteristic function, environmental conditions and internal parameters, through normal and log-normal distribution fitting transmittance of photovoltaic modules, change in series resistance and parallel resistance. Through the proposed photovoltaic modules degrading model, a large amount of simulation results shows that, with the modules degrading, the photovoltaic modules maximum power point will deviate and diverge. The major cause of output power decrease is short circuit current attenuation. The aging of parasitic resistances mainly influences short-circuit current and open-circuit voltage, and fill factor has little change with the degrading of system.

However, the penetration of DPVs in the individual power system is restricted due to the operational limits. Hence, the integrated electricity and heat system (IEHS) has been developed to improve the system flexibility and enlarge the penetration of DPV. This paper presents an optimal planning method of DPV in IEHS, which formulates the optimization model of DPV planning according to the modeling of the multi-energy networks. In order to reduce the curtailment of DPVs, the penalty cost of DPVs is integrated to the objective of the proposed planning model.
