Power Transfer Distribution Factors (AC-PTDF). In transmission lines, congestion is the important operational issue that often occurs in deregulated system. Congestion in the transmission line restricts the simultaneous delivery of power for set of transaction between generator and load. Thus it is important to manage and remove congestion and to appropriately charge the transmission system users that cause congestion. Many different methods Topological Generation Distribution Factors (D.C.), Traceable flow method, Optimal re-dispatch and Zonal congestion management have been used to determine the congestion cost. In the paper we will first report on the results of our comprehensive literature review on the topic as well detailing the outline of the promising preliminary methodologies investigate. The main focus of the paper will be on the methods for transmission line congestion cost management and calculation during transmission transactions. In our studies we will use full AC load flow analysis (Newton Rapson) to determine the power system quantities. MW-mile method will be used to determine the congestion cost in the system. This approach will allow us improve the accuracy and allocate the values fairly to the transmission line users most responsible for the congestion. Furthermore we will be reporting on our preliminary findings and conclusion of our efforts in trying to derive a practical congestion pricing methodology that will be accurate and can be accepted by all parties as equitable and practical and conclude by detailing the future stages of our investigations.","PeriodicalId":446482,"journal":{"name":"2015 50th International Universities Power Engineering Conference (UPEC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114938278","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, communication between the active devices in the system is a big challenge. In addition to providing communication between a large numbers of devices, it is necessary ensure the security on transmitted information. In this context, the use of mesh networks is an interesting alternative. The main feature of this type of network is the auto configuration of the topology and the high dynamic on active devices. The routing infrastructure is implemented by these devices, through exchange of routing tables between the nodes. Thus, it is necessary prevent unauthorized devices disclose routes or may transmit any data on the network. In this context, the authenticity and the integrity information's can be compromised by a false node. Among the protective measures that can be applied in this case highlights the use of authentication mechanism in each node. In these terms, this work presents a proposal to ensure the authenticity of the participating nodes of a mesh network, through signing the control messages of OLSR protocol via SECOM middleware.","PeriodicalId":446482,"journal":{"name":"2015 50th International Universities Power Engineering Conference (UPEC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122137073","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 has resulted in strict grid code requirements by utilities in order to ensure a reliable, safe and economically manageable grid operation. This justifies the need for adequate system models to represent overall system dynamics of grid connected renewable energy sources during normal and abnormal grid disturbances. Wind generation technology has become the world's largest growing energy source due to its non-emission of carbon gases, it is available in abundance and is reproducible. This research paper presents the different methods that can be used to aggregate a wind farm consisting of the doubly fed induction generator (DFIG) wind turbine for simulation sudies and predicting wind farm dynamic performance during normal and abnormal grid conditions. By comparing the aggregated wind farm models with the full wind farm model, this research paper confirms that the different aggregating techniques used in simulation studies provides identical results, hence confirming that aggregating techniques can be used to reduce computational complexities on the one hand and be able to predict the wind farm's influence on the system dynamic behavior on the other hand.","PeriodicalId":446482,"journal":{"name":"2015 50th International Universities Power Engineering Conference (UPEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132455863","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}
