This paper reveals a new cascading failure mode in multi-infeed high voltage direct current (HVDC) systems. Firstly, the mechanism of multi-timescale cascading failure is proposed. Then the simulation results of multi-infeed HVDC systems which is carried out in Power system department-Bonneville power administration (PSD-BPA) indicate that the dominant cascading failure modes in different timescales are different and they are coupling with each other. Finally, several dominant factors of different timescale cascading failure modes are pointed out.","PeriodicalId":416229,"journal":{"name":"2022 IEEE 5th International Electrical and Energy Conference (CIEEC)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124350115","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}

Hydrophobic cycloaliphatic epoxy resin is a new type of insulation material used in insulators. Ice accretion on insulators is a common phenomenon in alpine regions, which seriously threatens the safety of power grid. However, the anti-icing performance of hydrophobic cycloaliphatic epoxy resin has not been studied. In this work, the effect of polysiloxane content on the hydrophobicity and roughness of cycloaliphatic epoxy resin was studied. Then, the icing drop test and icing shear strength test were designed to analyze the effect of polysiloxane content on the anti-icing performance of cycloaliphatic epoxy resin. The results show that polysiloxane can significantly improve the static contact angle of cycloaliphatic epoxy resin. With the increase of polysiloxane content, the static contact angle increases. Polysiloxane has little effect on the surface roughness of cycloaliphatic epoxy resin, which shows that the change of static contact angle of cycloaliphatic epoxy resin is mainly affected by surface tension. Polysiloxane content is the dominant factor causing the change of surface tension. Polysiloxane modified cycloaliphatic epoxy resin can shorten the icing drop time, reduce the icing shear strength and improve the anti-icing performance. The anti-icing mechanism of polysiloxane modified cycloaliphatic epoxy resin can be described by icing shear strength of water freeze in Cassie state model. The static contact angle is the main reason affecting the icing performance of polysiloxane modified cycloaliphatic epoxy resin.","PeriodicalId":416229,"journal":{"name":"2022 IEEE 5th International Electrical and Energy Conference (CIEEC)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124354337","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 this paper, a photovoltaic trading mode based on Blockchain technology is proposed. The benefit function is constructed and Stackelberg game theory is used to get the equilibrium solution to determine the internal electricity price. Furthermore, a credit value is introduced to design a trading incentive mechanism, and the energy storage unit is installed, which ultimately avoids \"light abandoning\" phenomenon. The simulation results prove that this transaction mode using Blockchain technology increases the benefits of both buyers and sellers and improves the utilization rate of photovoltaic power generation.","PeriodicalId":416229,"journal":{"name":"2022 IEEE 5th International Electrical and Energy Conference (CIEEC)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124532045","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}

Configuring distributed synchronous condenser in renewables stations can effectively solve the transient voltage problem. In order to maximize the configuration effect, this paper proposes an optimal configuration method for distributed synchronous condenser that considers the characteristics of high-proportion renewables direct current transmission systems. This method uses the improved trajectory sensitivity to screen out the candidate installation nodes that can improve the transient voltage stability of the system with the application of the synchronous condenser. In order to improve the capability of the system voltage support, the minimum configuration capacity is optimized by using the multiple renewable station short circuit ratio. Then a regulator that satisfies the safety, stability and economy of the power system is obtained. The validity of the synchronous condenser optimal configuration scheme is verified through a typical example.","PeriodicalId":416229,"journal":{"name":"2022 IEEE 5th International Electrical and Energy Conference (CIEEC)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124142329","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}
