This method starts from combing the power grid business lines, goes through the process of service refinement, data classification, and data grading, and finally gives targeted protective measures. This method is in line with the actual operation of the power grid, and clarifies the responsible subject of data classification and grading, so it is easy to implement and facilitate the update of classification and classification. In the process of data grading, the degree of influence and scope of influence on multiple objects are fully considered, and the power grid data is divided into four levels to facilitate data management, which basically conforms to the status quo of power grid data classification and lays a foundation for power grid data governance.","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":"126782435","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 effectively utilize the slow-moving prime mover caused by stepping in the rack and pinion design, the researcher used a high pole count motor - a hybrid stepper motor as a generator. In addition, a flywheel was used to lessen the effect of torque in the hybrid stepper. The maximum power produced depends on the instantaneous force acted by the mechanical energy to rotate the generator. Hence, this study incorporates the implementation of a maximum power point tracker (MPPT). The main goal of this study is to design and implement a mechanical energy harvester using a hybrid stepper motor as a generator with an MPPT using an incremental conductance algorithm. A working dynamic model using Simulink was produced that can almost match the output electrical frequency of the motor used with the mechanical energy harvester. The mechanical energy harvester was constructed and was able to generate 5.9 Wmax with the MPPT controller, which is higher than the power produce with only resistive load, thus, confirming the merit of the MPPT. It was determined that there is a significant relationship between the charge produced by the mechanical energy harvester and the number of steps per second. Neglecting the idle current, transmitting current, and considering the data gathered for 98kg individual, it was found that it will take 18.7 hours or 122,377 steps for the mechanical energy harvester to fully charge the 12V 1.3 Ah battery.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"27 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":"129829538","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 efficient utilization of multi-source measurements to accurately estimate the state of distribution network is an important prerequisite for operational decision-making. In this paper, a state estimation method based on multi-source measurement data was proposed for distribution networks. The time scale, synchronization and accuracy of multi-source measurements were considered. The integration of PMU data into state estimation model was discussed. The measurement functions were linearized by equivalent conversion of multi-source measurements. The data fusion strategy for different data types was presented to improve the estimation accuracy and shorten the estimation period. Case studies on an actual engineering example was performed to show the effectiveness of the proposed method. The improvements in network observability and estimation accuracy under different measurement conditions were verified.","PeriodicalId":127339,"journal":{"name":"2023 International Conference on Power Energy Systems and Applications (ICoPESA)","volume":"24 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":"114715427","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}
