Implementation of fault current limiters (FCLs) to locally limit the DG fault current, could somewhat overcome with this problem. Kind and value of FCLs must be chosen by considering from an economical standpoint. Also connecting and disconnecting DGs to the power system according to network operating scheduling or other reasons make power distribution system (PDS) topology time varying and so optimal coordination of DOR will affect. In this study a new approach is proposed to solve these problems of PDS in the presence of DGs. In the proposed approach, settings of relays are chosen based on minimizing a new cost function that assume value of FCLs to be zero, If stopping criteria is satisfied, optimization is done and algorithm will finish. otherwise, the value of FCLs will raise and the algorithm will repeat until sopping criteria satisfy.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121698676","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}

Successful realization of this concept will in great part depend on efficient management of tremendous amounts of data to be gathered and processed in very short time periods. In this work we propose a novel smart metering architecture to manage data collected from deployed smart meters logically encapsulated in form of virtual meters. The metering infrastructure is structured in the form of Advanced Metering Infrastructure (AMI). The architecture of Meter Data Management (MDM) system and its integration in Control Center structure of power system is described in details.

Power transfer using magnetically coupled series resonators is maximized when the load presented to the sender is matched to the series impedance of the source. This determines an optimal separation distance between the sender and the receiver. However, the maximum power transferred only depends on the losses in the system and is independent of this distance and the resonant frequency. Closed-form expressions describe the power transferred and efficiency for all distances and system values. These expressions are validated with systems operating at 23 kHz, 40 kHz and 59 kHz. The performance of resonant magnetic coupling for wireless power applications is bounded to have efficiencies less than 50% at the maximum power distance and beyond. Higher efficiencies are only possible at shorter distances where the load presented to the sender is larger than the series impedance of the source.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129463674","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}

A traditional power system stabilizer (PSS) of the generator excitation system and a controller of the thyristor-controller series capacitor (TCSC) are considered. Good operation of both controllers delivers the required dynamic performance of the system. However, faulty condition signifies a degraded control signal of one controller at a time. The designed scheme proposes that the parameters of one controller switch to some predetermined values if the other controller is faulty with any degradation percentage. Preserving definite settling time of the dynamic response is guaranteed against continual degradation of either controller as the design is implemented by Kharitonov theorem and particle swarm optimization (PSO). The proposed design represents an indirect adaptive PSS. Results represent distinct effectiveness of the proposed design in keeping the desired system performance under sound and different faulty conditions.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127472357","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}
