Bubbles are the result of different stresses such as thermal, electric, and vibration that may lead to insulation failure in oil transformers. Recent studies emphasised on the dynamic effects of bubbles under different non-electric fields in engineering. However, additional investigations are desirable on the behaviours and mechanisms of bubbles under combined stresses of mechanical vibration and electric field. The present study investigates numerically the dynamic behaviours of a monodisperse bubble swelling in an oil transformer exposed to vibrations and an electric field. An established two-dimensional model was used to solve the Navier-Stokes, vibrational and electric field equations. The level-set approach was adopted to track the trajectory and shape of the soaring bubble. The influence of the electric field, vibration frequency, amplitude, and bubble size on air bubble motion and deformation sifted. The outcomes reveal that the bubble size, electric field, and vibration amplitude influence dynamic bubble characteristics. The electric field revealed its contribution to the bubble deformation rising from the initial point. The bubble rising rate showed a dependence on bubble size and vibration parameters.","PeriodicalId":425438,"journal":{"name":"2022 12th International Conference on Power and Energy Systems (ICPES)","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123241307","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}

In order to effectively reduce the adverse impact of wind power consumption on power grid, an optimal dispatching model of electricity-gas integrated energy system (EGIES) considering the uncertainty of wind power output is established. Firstly, based on the mathematical model of power grid, natural gas network and coupling equipment, the economic dispatch of integrated energy system (IES) is studied. In addition, the conditional value at risk (CVaR) theory is used to describe the risk loss faced by wind power uncertainty, and the risk loss function evaluated by CVaR theory is introduced into the objective function. Finally, taking IEEE33-24 as an example, it is verified that introducing CVaR into IES scheduling model can effectively reduce the running cost of the system and improve the running security. At the same time, the simulation results also show the influence of the change of confidence level and risk coefficient on IES.","PeriodicalId":425438,"journal":{"name":"2022 12th International Conference on Power and Energy Systems (ICPES)","volume":"7 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127931966","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, in this paper, a coalition-game-theory-based local energy transaction strategy is developed to solve the above problems. Firstly, the traditional model of microgrid in grid-connected mode and the coalitional transaction model are analyzed and established. Moreover, a typical matching method and the Shapley value are applied to calculate and allocate the utility of each valid coalition. And the optimal partition in the network is found by using coalition merge and split operations, a coalition-game-theory-based local energy transaction algorithm is proposed. Compared with the traditional operation mode, the simulation results show that the power transaction scheduling algorithm can effectively promote the cooperative transaction between microgrid, reduce the energy transmission loss, improve the individual utility of microgrid, and help maintain the coalition stability.","PeriodicalId":425438,"journal":{"name":"2022 12th International Conference on Power and Energy Systems (ICPES)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121027945","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, the energy flowing model is analyzed to adapt to the zero-carbon development. Then, considering uncertainties of renewable resources and load, three objectives with various constraints are constructed from investment cost, peak-load shifting and annual carbon emission. Also, the improved non-dominated sorting genetic algorithm (NSGA) is employed to solve it. Simulations on IEEE 33 bus with different green energy demonstrate that the constructed optimization models can achieve the balance of the investment and environmental protection. The proposed improved solving method may raise the convergence of solving nonlinear multiobjective under constrained condition.","PeriodicalId":425438,"journal":{"name":"2022 12th International Conference on Power and Energy Systems (ICPES)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116521411","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}

This paper proposes a data cleaning method for the abnormal temperature data of intelligent cable that considers the characteristics of the temperature rise of the cable. Based on the characteristics, the interpolation method is used to complete the missing data, and then through the consistency comparison of the temperature and current fitting curves, the processed temperature data is supplied to the operation and maintenance platform after passing through the filter circuit to ensure the accuracy of the data.","PeriodicalId":425438,"journal":{"name":"2022 12th International Conference on Power and Energy Systems (ICPES)","volume":"121 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128492002","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}
