However, the widely used marginal price mechanism is difficult to identify the externalities value of market members and the value of ancillary services provided by generators. To accurately identify the externality value of market members, the Vickey-Clarke-Groves (VCG) mechanism based on incremental costs was introduced. Compared with the marginal price mechanism, the VCG mechanism requires removing the generators sequentially and re-optimizing, which is computationally inefficient. An accelerated algorithm based on optimal base replacement is proposed, which uses the dual simplex method to perform optimal basis replacement based on the initial optimal basis to obtain the optimal solution of the new problem after removing generators. Case studies based on modified IEEE30-bus system demonstrate the significant improvement of the acceleration algorithm on the computational efficiency of the VCG mechanism.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127058868","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}

Meanwhile, the distribution network with a high proportion of new energy faces the challenge of high dispatch costs and difficulty of renewable energy accommodation. In order to improve the economy and reliability of distribution network operation. This paper proposes a bi-level optimal scheduling model for active distribution networks considering dynamic reconfiguration. The upper layer of the model is the distribution network reconfiguration model. The optimization objectives are the minimum total operating cost and the optimal power supply quality, which is a multi-objective optimization, the decision variable is the grid structure for each reconstruction cycle. The lower layer of the model is the economic scheduling model, the optimization goal is to minimize the total operating cost, and the decision variable is the output of each flexible resource. And the improved artificial fish swarm algorithm is used to solve the proposed model. Finally, an IEEE33 node power distribution system is used for the case study. From the simulation results, the bi-level optimization model can significantly improve the operation economy and reliability of the distribution network.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132608924","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}

For power electronic device, the inverter with high capacity is applied to supply a reversal phase voltage to compensate the fault voltage. Otherwise, the non-power electronic devices have longer reaction time and lower precision. Herein a hybrid flexible arc suppression method combining power electronic devices and non-power electronic devices is proposed. The operating characteristics of the hybrid flexible arc suppression system under multiple operating conditions is simulated in MATLAB/Simulink. The proposed method is verified in a 10kV grid reality test field. The result shows that the method can sufficiently reduce the voltage at the fault point to less than 300V, avoiding the reignition of the arc. The method can also greatly decrease the capacity of the active inverter from usual 50kVA to 10kV A. Moreover, both speed and accuracy of the arc suppression are improved.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133784206","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 current motor operation mechanism needs motors with low inertia and large torque to meet the opening and closing speed requirements, which limits the development of motor driving circuit breakers to high voltage level. In order to reduce the torque demand of the motor operating mechanism, this paper studied the feasibility of applying 252kV double-motion arc extinguishing chambers to the motor mechanism, and the relative displacement between two contacts and the torque curve during the opening and closing operation are calculated. The results show that the motor operating mechanism with double-motion mechanism can meet the speed requirements of the 252 kV circuit breaker. Compared with the single-motion mechanism, the demand for the maximum motor torque can be reduced by nearly 25%. The research shows that double-motion mechanisms help to reduce the torque requirements, which provides the possibility to apply the current motor driving circuit breakers to higher voltage levels.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130804362","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}
