Therefore, it is necessary to consider the voltage sag level of sensitive users to conduct site selection and capacity allocation of ESPSs. Firstly, the voltage sag severity of sensitive users is evaluated, the sensitive users are graded and quantified, and the comprehensive location coefficient of each node is determined according to the annual economic loss of sensitive users. Secondly, the energy storage cost optimization model, which considers the cost of ESPS itself and the cost of voltage sag detection equipment, is constructed. Thirdly, based on the comprehensive location coefficient of each node, the improved particle swarm optimization algorithm(MPSO) is used to obtain the capacity optimal allocation scheme of ESPS. Finally, the simulation results of IEEE33-bus distribution system show that the method in this paper has good applicability in optimal configuration of ESPS considering voltage sag.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"334 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122327888","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}

By drawing on the theoretical methods of carbon emission reduction and carbon emission measurement in supply chains both domestic and abroad, this paper forms a calculation method which is suitable for checking the carbon emissions of the supply chain of power grid enterprises in China. The method is able to calculate and grasp the real carbon emissions of the supply chain of power grid enterprises, so as to enhance the basic ability of power grid enterprises in green transformation, to formulate green carbon emission reduction directions, to help the green transformation of energy supply chains, and to ultimately serve the national double carbon strategy.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115015845","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 ensure an accurate prediction, in this paper, a regional distributed photovoltaic short term power prediction method based on stacking ensemble learning and cluster analysis is proposed. In the proposed method, several weather patterns are firstly identified by using the K-means++ algorithm based on the historical data. Then, for each weather pattern, all the photovoltaic panels are clustered into several groups based on the k-Shape algorithm, where a prediction model for each photovoltaic cluster is established by employing the Stacking ensemble learning algorithm. Finally, based on the numerical weather forecast (NWP) of the forecast day, we select the best suited weather pattern and obtain the final prediction result by employing the trained prediction model under this weather pattern. The effectiveness of the proposed strategy is verified by the actual dataset.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"243 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130758362","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}

However, how to balance the low-carbon cost and economic cost and realize the scientific planning and access of multiple flexible resource forms such as “source”, “storage” and “load” to the active distribution network (ADN) remains to be solved. Therefore, a bi-level planning model of the ADN was developed, which aims at carbon cost and economy, considering multiple flexible resource access. In the upper level planning, the distributed generations (DGs) and energy storage systems (ESSs) are located and rated with the objective of economy. In the lower level planning, the DG, interruptible load, and ESS are co-optimized with the objective of reducing network loss, and the modified particle swarm optimization algorithm is proposed for solution. The case study results show that the improved solution model can reduce carbon emissions obviously, and ensure the lowest comprehensive cost and realize ADN low-carbon economic operation.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131086836","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}
