At present, isolated power grid is an effective way for utilizing and consuming the renewable energy. Nevertheless, due to the high penetration of renewable energy in isolated power grid, the inertia of the system is insufficient. When the active power disturbances occur, system frequency will fluctuate greatly, which will seriously affect the safe and stable operation of isolated power grid. Therefore, it is of great significance to clarify the frequency dynamic characteristics of isolated power grid. The topology of an actual isolated power grid is given first in this paper, and a frequency response characteristics model which is suitable for frequency characteristics analysis is raised. Then a synchronous generator penetration coefficient is defined, and the frequency response characteristics of the isolated power grid are analyzed in two different cases as renewable energy does not participate in frequency regulation and participates in frequency regulation through droop controller. Subsequently, a relationship curve of power disturbance, frequency deviation and synchronous generator penetration coefficient is shown in this paper. Finally, the proposed frequency characteristics analysis method is verified based on PSCAD/EMTDC simulation test platform.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133130105","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}

Dynamic voltage restorer is an effective method to tackle voltage sag and the control system is the most component of dynamic voltage restorer. The conventional proportional-integral control which has the advantages of designing simple and higher speed is a widely used control method in dynamic voltage restorer, but the proportional-integral control usually needs to regulate parameters to improve control accuracy for nonlinear system. In this paper, a fuzzy adaptive proportional-integral controller is proposed to control dynamic voltage restorer to mitigate the voltage sag issue. The fuzzy adaptive proportional-integral controller helps to complete a precise compensation and a faster-responding speed compared with a conventional proportional-integral controller. Moreover, the total harmonic distortion with fuzzy adaptive proportional-integral control caused by power electronic components also decreases. Finally, the effective results are validated through the simulation analysis of MATLAB/SIMULINK.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127814686","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}

Firstly, based on the working mode analysis theory, an on-line identification method of wind turbine blade modal parameters based on the transmission rate is constructed, and a blade vibration physical experiment platform is built for the experimental verification of this method. Through the comparison with the experimental results of the traditional force hammer excitation method, the accuracy of the working mode parameter identification method is verified; Then, taking the 5MW offshore wind turbine in fast simulation software as an example, the multi condition operation simulation of blade damage is carried out, and the influence law of blade damage on the normal operation parameters and blade modal parameters of the unit is obtained through data analysis; Finally, using different combinations of blade monitoring data, the accuracy of machine learning algorithm (MLA) applied to blade damage fault diagnosis is tested.

The national policy clearly supports the development of grid-side functional alternative energy storage, and proposes to explore the possibility of incorporating it into the transmission and distribution price. At present, grid-side functional alternative energy storage is in its initial stage of exploration, and its substitution effect is in urgent need to be further studied. To this end, this paper proposes a method to evaluate the substitution effect of grid-side functional alternative energy storage and applies it in the typical cases of seasonal and temporary load growth to conduct research. It is concluded that for seasonal and temporary load areas, the use of mobile energy storage solution is not as economical as line transformation when only taking into account the single-application scenario of dealing with seasonal load every year. Following the decreasing of energy storage cost and the application of mobile energy storage devices in multiple dimensions, mobile energy storage is an important option for solving the problem of electric power supply in such areas.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115910756","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}

Therefore, this article first establishes traction substation model, traction network model and train model with on-board brake resistance, and builds the simulation calculation platform for urban rail traction power supply system. Then, through the analysis of the typical dual train operation model, the optimization objective is to reduce the output energy of substation and reduce the start of on-board brake resistance. And for energy interaction period and non-interaction period, a two-stage optimization strategy is proposed to adjust the train operation curve. On this basis, according to the characteristics of train timetable, a collaborative optimization strategy of multi-train operation based on the sequence of train braking is proposed. Finally, a hardware-in-the-loop experiment platform is built to verify the optimization strategy of train operation curve under multiple operation scenarios. The results show that the strategy can effectively enhance the utilization of regenerative braking energy and improve the energy saving effect of the system.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117067596","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}
