Taking 400 kV field equipment as the research object, seismic responses of four types of connection schemes, which include rigid conductors with fixed fitting, sliding fitting, and flexible conductors of two different sag-to-span ratios, were compared. The results show that the post insulators connected with the loop device have larger seismic responses. Interconnection mode has a huge influence on the displacement and acceleration responses of the device. The lower frequency device connected by flexible conductors has an obvious unidirectional oscillation phenomenon of displacement and acceleration. There exists a critical value of the sag-to-span ratio. The sag-to-span ratio of flexible conductors below the critical value will cause a larger peak seismic response of the device in the loop. The analyses reveal that rigid conductors with fixed fittings can be adopted in the lower intensity of seismic fortification because of fine integrity and smaller displacement. Both sliding fitting connections and flexible conductors are suitable for the area with high seismic intensity in view of smaller acceleration response. Meanwhile, the setting of the sag-to-span ratio should be paid attention to the flexible conductors.","PeriodicalId":411512,"journal":{"name":"2021 3rd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129887785","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 differentiation of power grid characteristics and the resulting diversity of stability control strategies determine that it is difficult to standardize the stability control system, and the stability control strategy is superimposed. In the process of machine realization, the degree of automation is not high, and personalized programming leads to hidden faults that are difficult to find through conventional means. Therefore, this paper proposes an automatic realization method of SSC code based on activity diagram. First, it sorts out the basic element configuration of SSC strategy and analyzes the relationship between them. Then summarized four procedures of SSC strategy implementation, using a unified description method of the SSC strategy to associate SSC model with the strategy code of SSC device, using standardized model analysis and code Generate tools to automatically generate device codes for SSC strategies. Finally, an engineering example is given, which uses automatic code generation tools to analyze and verify the correctness of the model and the practicability of the code.","PeriodicalId":411512,"journal":{"name":"2021 3rd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128454068","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}

In addition, the on-site hydrogen generation and storage of hydrogen for hydrogen refueling stations (HFSs) is currently the most economical hydrogen production solution. Conventional studies usually ignore the independent entity of WT and HFSs and regard them as one entity for joint operation optimization. In this paper, a cooperative operation model of WF and HFSs based on cooperative game is established, and a benefit sharing method based on the contribution degree of energy trading in cooperation is proposed, which overcomes the shortcoming of too high computational complexity of Shapley value allocation when the scale of HFSs is large. Simulation results shows that the cooperation can greatly reduce the cost of HFSs and improve the operation benefit of WT. In addition, compared with the Shapley value method, the proposed it accelerates the calculation speed and improves the enthusiasm of energy interaction between players.
