A hierarchical access control strategy based on multi-attributes is established by mining the relationship of attribute permissions among data access roles in power Internet. The experiment shows that the average operation time of the new equipment's network access and certification is in the order of ms, which effectively meets the high requirements of timeliness and security of the power system. The access control strategy can meet the requirements of multi-entity and multi-role access in the power Internet scenario, and can monitor and identify the behavior compliance of various access Equipment, which greatly improving the communication security and efficiency between power Equipment.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128473825","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}

Power spot markets are established in 8 provinces in terms of national market reform of power industry. Accordingly, conventional power system planning should be adjusted to accommodate to the new era power system. In the paper, an optimal integrated planning method in the purpose of meeting renewable accommodation target with consideration of economic impact to the spot market is proposed. A chronological production cost simulation model with security constraint unit commitment and locational marginal price calculation is used to simulate the power spot market. A root-cause analysis of renewable curtailment based on simulation results is designed to initially determine planning alternatives including transmission upgrades and energy storage systems. Optimal integrated planning is achieved based on the quantitative analysis of economic impact of planning alternatives using the simulation model. A case study using an actual provincial power system with spot market environment shows that the proposed planning method is able to provide the economically reasonable planning alternative with meeting renewable accommodation target.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129314802","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 improve the power estimation accuracy for the state estimation in energy management system (EMS), this paper proposes a graph-based reactive power estimation method for transmission lines to overcome the complex network topology processing problem related to the connections of shunt reactors. To achieve efficient and accurate solution for state estimation, this paper developed a graph data model for power system modeling in EMS application and leveraged the advantages of graph computing in handling the topology analysis and achieving parallel computing for state estimation. Based on proposed graph data model, a graph computing based approach is developed to allocate the injected reactive power of the shunt reactors to transmission lines and a nodal paralleled state estimation algorithm is proposed to incorporate the impact of shunt reactors. Finally, the effectiveness of the proposed approach is verified on an existing large-scale power transmission system.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129533226","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 challenge ahead for utility operators is to manage the operation and maintenance of a plant efficiently under the given circumstances. Therefore, the utility operators need to estimate the load so that there is no significant demand and supply mismatch. In the residential sector, the power consumption varies in every household, significantly depending upon the socio-demographical features, e.g., income, family size, age of resident etc. It is crucial to understand the relation of these socio-demographics on electricity consumption for its accurate forecasting. Besides, the smart meters in residential sector has made it possible for the household consumption to be known. A good estimation of load consumption at different levels is very important for efficient load management. Therefore, this paper focuses on developing a hierarchical structure by mining the electricity metered data to form customer clusters based on energy consumption patterns. To improve the forecasting performance, every cluster is associated with its distinct socio-demographical features. Based on the analytical results, it is evident that the hierarchical structure including socio-demographical features has the prospect to forecast load using a top-down approach, with an improvement in its mean absolute percent error by 9.04%, as compared to state-of-the-art bottom-up approaches.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130619754","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}
