The experimental findings indicate that the mean grain size of ZnO varistor ceramics become larger as the sintering temperature increases, and the grain boundary nonlinearity coefficient and potential barrier height first increase and then decrease. When the sintering temperature is 1050°C, the grain size of the ZnO varistor ceramic sample is better, the grain boundary barrier height is the highest, and the comprehensive electrical properties are better. Compared with the common 1100°C$sim$1200°C in the literature, it not only reduces the energy consumption but also improves the performance of ZnO varistor ceramics. It is speculated that the uniform distribution of doping ions before sintering reduces the sintering temperature. The lower temperature reduces the volatilization of oxide additives such as bismuth oxide and avoids abnormal grain growth.","PeriodicalId":402897,"journal":{"name":"2022 IEEE International Conference on Power Systems and Electrical Technology (PSET)","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116258789","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, problems such as wind and solar power curtailment and large carbon emissions still exist. Based on the framework of virtual power grid, this paper proposes a novel virtual power plant market game model considering the clean energy consumption weight factor to find a way out of the dilemma from the perspective of power market. The model is constructed in the form of two-layer. The goal of the upper layer is to maximize the profit of the virtual power plant and the lower layer is to minimize the power purchase cost of the system operator. Considering the mutual coupling between the upper and lower optimal results, the two-layer game model is reduced to a single nonlinear model with KKT (Karush Kuhn Tucker) theorem. And the nonlinear model is approximately linearized based on the strong duality theorem and big M expansion method to obtain the optimal solution efficiently. The project example results show the fluctuation of clearing price is reduced, which is more conducive to the smooth operation of the power market.","PeriodicalId":402897,"journal":{"name":"2022 IEEE International Conference on Power Systems and Electrical Technology (PSET)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114654425","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}

Motor-Generator Pair is capable of leading phase operation, which can effectively restrain overvoltage. In this paper, based on the grid-connected structure of the MGP, the transient and sub-transient characteristics of MGP are analyzed, it is pointed out that the power angle and excitation regulation of the generator are the key factors to improving its dynamic reactive power compensation capability. Then, based on the fast response of the converter, a fast active power reduction and additional excitation control strategy are proposed, which takes the blocking signal and AC voltage of the converter station at the sending end as input signals, aiming at increasing the depth of MGP leading phase. Finally, based on PSCAD/EMTDC software, the simulation model of multiple new energy stations connected to grid through DC transmission is built, and the effectiveness of the coordinated control strategy is verified. The results show that the proposed strategy can enhance the transient overvoltage suppression capability of MGP at sending end.","PeriodicalId":402897,"journal":{"name":"2022 IEEE International Conference on Power Systems and Electrical Technology (PSET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129325933","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, the existing equalizing methods are mainly based on the single operation mode of the distribution network, and the operation mode has poor adaptability. In order to improve the adaptability of the operation mode of the static equivalent of the distribution network containing distributed PV, this paper proposes a static equivalent parameter estimation method for the distribution network with distributed PV based on particle swarm optimization (PSO) and convolutional neural network (CNN). Firstly, aiming at the equivalence problem under each single operation mode, the equivalent model of the distribution network with distributed PV is constructed, and PSO identifies the transformer and line parameters. Finally, in order to improve the efficiency of model parameter calculation, a CNNbased static equivalent parameter estimation model of distribution network with distributed PV is proposed.

Applied to data-driven dynamic security assessment, electrical coordinate can improve dynamic security assessment accuracy significantly. Based on the concept of the electrical coordinate system, an expansion method of the electrical coordinate system is proposed, which further improves the accuracy of dynamic security assessment. First, the reasons why the representation accuracy of the electrical coordinate system is low in partial areas are analyzed. The blind point, blind line, and blind area for fault location feature expression are defined. Then, by analyzing the electrical relationship between two points, the judgment criterion of blind lines is determined, and the rapid searching method of blind lines is proposed. Finally, the identification and fine-tuned algorithm of blind area is proposed. The electrical coordinate system is expanded by supplementing reference nodes. And the framework of data-driven dynamic security assessment based on expanded electrical coordinate system is constructed.
