The framework combines the use of optimally deployed real-time power flow sensors and that of load estimates via Advanced Metering Infrastructure (AMI) or load forecasting mechanisms. The distribution network is modeled as a tree network. It is shown that the outage detection problem over the entire network can be decoupled into detection within subtrees, where within each subtree only the sensors at its root and on its boundary are used. Outage detection is then formulated as a hypothesis testing problem, for which a maximum a-posteriori probability (MAP) detector is applied. Employing the maximum misdetection probability Pmaxe as the detection performance metric, the problem of finding a set of a minimum number of sensors that keeps Pmaxe below any given probability target is formulated as a combinatorial optimization. Efficient algorithms are proposed that find the globally optimal solutions for this problem, first for line networks, and then for tree networks. Using these algorithms, optimal three-way tradeoffs between the number of sensors, the load estimate accuracy, and the outage detection performance are characterized for line and tree networks using the IEEE 123 node test feeder system.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130210978","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 value of each technology depends, however, not only on the characteristics of the plant in question but also on the rest of the generation portfolio. Thus the correlations between various generation technologies, as well as the characteristics of the technology itself, will drive the final generation portfolio. Monte Carlo analysis is employed to determine the distribution of returns of and correlations between various electricity generation technologies. The operational costs of each technology are arrived by means of a unit commitment and economic dispatch algorithm. The revenues of each generation unit are calculated according to the marginal cost of electricity provision at each hour; ie a perfectly competitive market is assumed, and the NPV of each generation technology is determined. Significant anti-correlation exists between the value of different technologies depending on operational considerations, while anti-correlation due to varying fuel-types does not feature in the results.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134076185","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}

Since load consumers are major beneficiaries of the transmission network therefore, the transmission tariff allocations as well as the revenue reconciliation are being evaluated keeping them in consideration. The impact of power flow through a line due to MW or MVA withdrawal at a load bus has been derived using power flow analysis. The optimal parameters of power flow are determined for both actual and base loading of any circuit. The work presents methodical evaluation of transmission tariff allocation, has been performed with the three variants namely absolute, dominant and reverse. Multiple cases of the circuit utilization are simulated to the support findings more general. The tariff allocation to load buses reduces with increase in the line utilization for any variants used. Therefore, for economical tariff allocation and better revenue reconciliation, it has been recommended that, the average utilization of the network should maximum, for any variant used.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"66 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131727453","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}

Turbo generators are consequently experiencing problems, including increasing electromagnetic force, temperature rise of armature coils, etc., as we try to increase the armature current to keep pace with the capacity increase. One way of avoiding these problems is to increase the number of parallel armature windings for decreasing the armature current per coil. However, the circulating current in the parallel windings is generated by the difference of the linkage flux of each winding, when the number of parallel windings is not a divisor of pole numbers. In this paper, we propose a simple method to calculate the circulating current by using a magnetic circuit in the design phase. We confirmed the proposed method has a similar accuracy and faster performance in comparison with the finite element method (FEM) analysis. And then we applied the proposed method to a calculation of the circulating current in 2- and 4-pole generators and considered the factors affecting the circulating current.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131837584","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 distribution circuit parameters considered here are; location of the service transformer with respect to the substation and location of the EV loads within the secondary service. The voltage analysis is carried out using a 13.8 kV distribution feeder dominated by residential loads. The study reveals that EV charging affects the secondary voltage more significantly than the primary voltage. The short-circuit capacity even at the remote end of the primary distribution line is adequately high; hence, preventing EV loads from affecting its primary voltage. When four 240V/16A EV loads in a secondary service nearby and remote from the substation are charging, the additional voltage drops in their respective primary voltages are 0.023% and 0.13%. However, because the short-circuit capacity at the secondary service wire for both locations (remote/nearby) is significantly lower, additional voltage drops of approximately 4.5% occur in the secondary service voltages. The study also reveals that a single EV load installed on a distant load node from a service transformer leads to comparatively higher additional voltage drop (1.7%) than an EV on a nearby load node (0.81%) in the same secondary service.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117311973","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}
