As an emerging distributed shared database technology in the Internet era, blockchain is related to the characteristics and it have a natural fit with the energy Internet, which brings a development opportunity to the traditional power transaction. This paper selects the microgrid operator (MO), energy aggregator (EA) and large power user (LC) as the distribution side the main body of electricity trading, built a power distribution side power market trading platform under blockchain technology, with the goal of maximizing benefits and minimizing costs, and established an active distribution network power trading optimization model based on cooperative evolutionary games,and use NSGA2 genetic algorithm to solve. And on the basis of the obtained optimization results, the Shapley value method is used to distribute the benefits of the power purchase cost of large consumer. The solution result of the optimization model is the basis for the generation of the smart contract. The calculation example results verify the feasibility of the smart contract model and the functional characteristics of the blockchain as a distributed ledger.","PeriodicalId":412421,"journal":{"name":"2022 4th International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124370412","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}

Considering that the substations are complex in the background and the targets are distinct in sizes, shapes and rotation angles, we propose a progressive feature fusion and refinement network (PF2RNet) for substation rotating object detection. In the network, ResNeSt50 is used as the backbone to improve the feature extraction ability, and the deconvolution feature fusion module is designed to generate richer semantic information. To perform better in substation scenes, the rotating anchors are used to reduce the Intersection over Union between anchor boxes. Besides, the feature refinement module is introduced to realize the regression process from coarse to fine, strengthen the feature information of the object location, and then alleviate the feature misalignment. Finally, experiments demonstrate that the mAP of PF2RNet on the substation multi-object dataset reaches 89.3%, which is improved by 5.2% compared to RetinaNet.","PeriodicalId":412421,"journal":{"name":"2022 4th International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"358 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123551431","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}

But different from conventional two-level converter, the power loss distribution inside submodules is uneven which will threaten the reliability. In this article, a reliability assessment model considering the device-level uneven power losses is proposed. Then influence of power loss distribution and redundancy schemes are investigated through a case study. The results illustrate that more unbalanced power loss distribution will result in reduced reliability. And improved modulation strategy can reduce the loss imbalance inside submodules. It is also found that passive redundancy scheme works better than active redundancy scheme in improving reliability as the failure rates of bypassed submodules are much lower than operating submodules. And passive scheme with 20% redundancy rate of full-bridge submodules is a good choice for redundancy design which both meets 20-year B10 lifetime requirement and saves cost.","PeriodicalId":412421,"journal":{"name":"2022 4th International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127023679","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}
