The existing demand-side market lacks an effective guidance mechanism for carbon emission reduction. This paper modifies the existing demand response market by introducing carbon emission control, including the carbon emission constraint and the CO2 price from the carbon market. The OPF-based acquisition of marginal emission factors is used to quantify the carbon emission reduction. Case studies show that the modified demand response market can not only achieve demand-side carbon reduction, but also increase the surplus of demand response resources. The introduction of the CO2 price can reduce the payment from the market to demand response resources, which provides a viable source of funding to facilitate the participation of demand response.","PeriodicalId":187017,"journal":{"name":"2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126105664","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}

Since the heat dissipation condition of cables in seawater is much better than that in air, the limiting effect of the air section of the J-tube on the carrying capacity is more significant. This paper takes ± 400 kV DC submarine cable under the J-tube laying environment as the research object, and a three-dimensional simulation model of the air section of J-tube is established using COMSOL Multiphysics software to study the influence of ambient temperature and pipe's outer diameter on cable's steady-state carrying capacity. The results show that with the increase of ambient temperature, J-tube submarine cable's carrying capacity will be significantly lower, from 2015A in 10°C down to 1386A in 40°C. And as the outer diameter of J-tube increases, the current carrying capacity of the cable also increases, because air flow in the tube also becomes more intense.","PeriodicalId":187017,"journal":{"name":"2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122372309","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 traditional data-driven methods use the training data samples to train the samples and ignore the data distribution differences.

To address this problem, we proposed a transfer convolutional neural network (TCNN), which considers both of the classification loss on the domain data samples and the domain transfer loss. In this way, the proposed model has higher transferability and generalization ability on the testing samples, and thus the classification performance has been improved. tal results validate the effectiveness of the proposed method.","PeriodicalId":187017,"journal":{"name":"2022 4th International Conference on Electrical Engineering and Control Technologies (CEECT)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125541622","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 fully improve the system performance, this paper proposes a two-stage integrated energy system intraday scheduling optimization method considering equipment nonlinearity. First, to minimize the operation cost and consider the linear characteristic constraints of equipment, a linear programming model for the optimal scheduling of the intraday economy is established. Then, based on the linear optimization results and considering the nonlinear characteristics of equipment, a nonlinear optimal scheduling model is established, and the nonlinear optimization method is used to further improve the optimization accuracy of the load setting values of each equipment.
