The existence of metal particles poses a huge threat to the insulation performance of GIS. The previous research on free metal particles in GIS mainly focused on the force analysis of the two-dimensional radial plane particle movement, ignoring the influence of the spacer on the axial movement of the particles. In this paper, by establishing a three-dimensional simulation model with spacers, the influence of spacers on particle axial electric field distribution is studied. Based on the analysis of the force of two-dimensional radial plane particles, the influence of axial electric field on particle movement is further studied. The results show that the direction of the electric field on the concave side of the spacer is directed from the spacer to one end of the pipeline, and the particles are subjected to the axial electric field force directed to the spacer. The particles are finally mainly concentrated near the spacer. The actual GIS experiment platform was taken to verify the simulation calculation results.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"369 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133364558","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}

To achieve a more cost-effective functionality and enhance the reliability of smart microgrids, innovative techniques for cyber-attack detection and cyber-resilient control need to be addressed. For this purpose, this paper considers various distributed generation resources, including wind, solar and battery, as a hybrid renewable microgrid. A novel model-based cyber-attack detection and diagnosis scheme based on fuzzy modeling and identification approach is presented for the PV system at microgrid level. Also, an integrated cyber-resilient controller for the DC/DC pulse-width modulation (PWM) converter is proposed to mitigate the impacts of cyber-attacks. Finally, simulations are performed in MATLAB/Simulink environment to demonstrate the effectiveness of the proposed approaches.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133069380","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 high temperature of the local flue gas will trigger the start of the water spray desuperheater system, which will easily lead to water vapour condensation and block the bag. The flow field of the flue at the inlet of the dust collector was tested, and on this basis, a numerical simulation was carried out, and finally, a baffle installation plan was designed. The flow field test results after the implementation of the baffle modification show that the uniformity of the inlet flue gas temperature and flue gas velocity distribution of the bag filter has been significantly improved.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133308721","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}

Flexible energy facilities, such as high-voltage electrode boiler, can be integrated into coal-fired power units to participate in frequency regulation service. One of the key issues of the integrated scheme is how to dispatch high-voltage electrode boiler properly. To achieve it, this paper proposes an optimal economic scheduling approach for electrode boilers based on two-stage stochastic programming. Statistical characteristics of the AGC signal, the auxiliary service market rules and performances of different units are fully considered in the process. We finally determine the optimal operating base point and output of the electrode boiler in frequency regulation. Compared with the stochastic simulation using Monte Carlo approach, this approach is much less computationally heavy and easier to implement. A power plant case shows that the reasonable scheduling of the highvoltage electrode boiler using the proposed approach can realize the complementary advantages of different units, thereby efficiently improving the regulation performance and revenue.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"84 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134162858","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}

Many studies have forecasted the structures of China's energy as well as pathways and measures. Considering the characteristics of electric power system and the electrification development, this study proposed an assessment strategy to analyze the applicability of pathways to electric carbon peak in a region. Taking a certain region for an example, this paper comes up with two scenarios, high imported power and high nuclear capacity, by using the optimization model. Then, it compares these two pathways through evaluating the economic efficiency, reliability and security of power system, and carbon targets. Though lower cost per kWh of high nuclear scenario, taking into account the power system reliability and total carbon emission level, a high receiving ratio of power is a better choice for this certain region.","PeriodicalId":136285,"journal":{"name":"2021 IEEE 4th International Conference on Renewable Energy and Power Engineering (REPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129158451","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}

To solve the problem, the energy storage system and the DFWPG are combined to involve in the frequency regulation of wind power system in this paper. The DFWPG is controlled by the virtual inertia frequency regulation and the pitch control. The output power of the energy storage system is adjusted by using the droop control.
