In order to solve the probabilistic forecasting problem of energy time series, we develop a novel transformer-based decomposition framework, i.e., the temporal decomposition transformer (TDT) to estimate the probability distribution of future time series. TDT achieves accurate and reliable probabilistic forecasting by predicting the mean and standard deviation of time series successively through the decomposition framework. TDT uses the tranformer decoder to capture the temporal feature in the historical time series, and then two tranformer decoders predict the mean and standard deviation of the time series at each future time instant respectively, where the standard deviation is forecasted based on the forecasting of the mean. Finally, the time series probabilistic distribution is modeled by log-likelihood regression. By accomplishing extensive experiments on two real-world energy time series datasets, we conclude that TDT achieves better forecasting accuracy in both point forecasting and probability energy forecasting than compared methods.","PeriodicalId":391372,"journal":{"name":"2022 First International Conference on Cyber-Energy Systems and Intelligent Energy (ICCSIE)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131543109","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}

Combined with wind turbine simulation software GH Bladed, the wind turbine unbalance model of 3MW wind turbine was built, and the fault types were identified by comparing the amplitude changes of 1 times turbine frequency in the marginal spectrum diagram under different working conditions, and then the proportion of each fault type was determined by the value of marginal spectrum entropy.

To overcome this problem, by estimating the left eigenvector of the graph Laplacian matrix, a novel integrated distributed control strategy is proposed, which consists of the distributed optimal reference generator and the tracking controller. By applying this control strategy to the microgrid system, the active power outputs of the systems exponentially converge to the optimal solution of the economic dispatch problem.

Then, based on Nash bargaining theory, a distributed optimisation model of the multi-energy microgrid cluster is established. With the objective of maximising the benefits of the alliance between each multi-energy microgrid (ME-MG), the power trading volume between Microgrid operator (MGO) and Distribution network operator (DNO) and it between MGO are solved to obtain the power trading volume. With the objective of maximising the benefits of each ME-MG, the trading electrovalence between MGO is obtained.
