In this paper, a modeling of IEC 61850 for protection and control in smart power distribution system based wireless communication network using the OPNET Modeler is implemented, including information flow model and IED model. These configurable wireless communication models make it easy to establish IEC 61850 WLAN wireless communication network for communication-assisted protection and control design and evaluation in smart power distribution system.

In the future, spot market will be established, the scientific and reasonable mid-long term physical contract decomposition can not only discover the true value of transported power, but also avoid adverse effects of frequent temporary curves adjustment in the market. In this paper, by establishing a mid-long term inter-provincial contract power decomposition optimization model that utilizes the total amount of abandoned water and the proportion of abandoned water power as the optimization goal, the power curve decomposition from month to day and then from day to hour is realized, and the daily delivery is designed. The rolling optimization method of the model that is delivered day by day is established, and the complete framework protocol power decomposition delivery process is combed out. Finally, the mixed integer linear programming method is used to verify the model by taking the mid-long term physical contract power decomposition of the IEEE-39 node system including cascade hydropower as a case study. The results show that this model has a significant improvement over the traditional model in terms of abandoned water control and power decomposition accuracy.","PeriodicalId":221387,"journal":{"name":"2021 China International Conference on Electricity Distribution (CICED)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123328440","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 above factors affect the fault judgment of dispatchers, slowing down the command response speed and prolonging the rush-repair progress and outage time of power failure.To solve the above problems, this research is put forward. An active rush-repair strategy based on association relation method is proposed. An intelligent fault diagnosis based on BP algorithm is proposed. To optimize the process of dispatching command, \"Marketing-Distribution-Dispatch-Repair\" rush-repair database is proposed. The case analysis shows that the research plays a positive role in the rapid judgment of fault causes, the acceleration of rush-repair command speed and the shortening of fault outage time.
