The hallmark of modern power systems is a highly integrated, flexible networked and communicative cyber-physical infrastructure having both continuous and discrete dynamics. Issues arising due to the complexity of these systems can be potentially solved by designing power control algorithms based on the information available at any instant of time. One of the developing technique is hybrid control which is mainly featured for a system under different operating conditions and in different operating states. This paper presents a unique approach for modeling and control of a smart grid considering its hybrid and complex nature. A model of smart grid has been developed with communication-assisted hybrid control strategy. The information on power flow management is updated to the operator through a feedback mechanism in order to meet desirable efficiency and reliability standards.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82554688","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, correlations between topological measures and vulnerability are not yet fully evidenced in the literature. These correlations have been studied for the entropy-degree and electrical-betweenness measures. Here, firstly, we provide supporting evidence on this respect by comparing the net-ability measure to the system-overload-index for the IEEE 30-bus and 118-bus base-case models, when doubling or removing lines, and for N-1 and N-2 contingency cases. Secondly, a new topological measure, average-equivalent-impedance, is proposed for the identification of potential locations to install voltage control devices. The results of this topological measure were validated by comparing them to the maximum-loading of each bus in both IEEE models and also to other device location optimization methods.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"111 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83556873","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 strategy adopted to ameliorate this potential menace is shifting electricity supply away from today's centralized service model towards a more dispersed structure. Sequel to the non-centralized operational paradigm is the penetration of V2G at the nodes of the electric distribution network. A V2G facility has the potential to provide economic incentives in an electric distribution network. In this paper, economic models are developed to quantify the amount of economic incentives that can be derived from the penetration of V2G into the power distribution network. Different V2G operational strategies are considered, and then observing how this operational changes impact economic incentive due to V2G penetration in the system. Three novel economic models were developed: (1) economic model to quantify the prospects of V2G when used for ancillary services in power systems, (2) economic evaluation due to released energy in the distribution network when V2G penetrates the system, and (3) the impact of location, V2G capacity and feeder loading on annual economic incentives. The results show that V2G promises significant economic incentives. The results obtained in this study emphasize the importance of proper system studies that considers different scenarios of V2G operational strategies.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"112 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91359096","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 approach is based on recognizing that measurements of bus injection currents Ibus can be viewed as signals produced by a random process. In this manner, the corresponding bus voltages Vbus are also stochastic signals that are related through a cross-covariance matrix to the injection current vector Ibus. Using estimation techniques developed for statistical signal processing, the cross-covariance matrix is shown to be Ybus. The increasing use of synchrophasors has enabled large-scale data collection of time synchronized bus injection currents and voltages. The new Zbus estimation method is applied to the IEEE 68 bus benchmark system to demonstrate the validity of approach. The accuracy and convergence rate of the method is evaluated under conditions corresponding to wide-area synchrophasors data collection. The results indicate that the method is broadly applicable to determining Ybus and Zbus for electric power transmission and distribution systems equipped with synchrophasor data collection technology.IEEE 68 bus benchmark systemwide-area synchrophasors data collection.electric power transmissiondistribution systemssynchrophasor data collection technology.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"73 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80368567","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}

Traditional centralized methods may not be an effective and economical solution, since a sophisticated communication network is needed to collect global information and a powerful central controller is required to process huge amount of data. This paper proposes a distributed method to optimize the overall social benefit and maintain the supply demand balance in a smart grid, considering three different types of load models including electric vehicle, air conditioning, lighting and electronic devices. Only information exchange among neighboring nodes is utilized, which enables the sharing of the computation and communication burden among local controllers to simplify the communication network and avoid the investment of expensive and powerful central controller. The effectiveness of the proposed distributed method is demonstrated through the simulation in the IEEE 14-bus system.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"3 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74819299","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 work implores the karush- Kuhn-tucker (KKT) condition to transform the two level formulation into a single level mixed integer linear programing. The optimization strategy receives the modeled thermal and electric load as input and optimizes the output of the distributed energy resources through the implementation of an energy management system (EMS). It further analyzes the available investment options of the microgrid using capital budgeting techniques to determine the return on investment to a microgrid stakeholder. The approach, though applicable to all microgrids, is developed within the context of an urban microgrid. Results obtained through its application show significant savings in energy cost and related microgrid benefits to stakeholders.","PeriodicalId":6497,"journal":{"name":"2016 IEEE/PES Transmission and Distribution Conference and Exposition (T&D)","volume":"17 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2016-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73149623","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 primary goal is to study the phenomenon of delayed voltage recovery by applying multiple instances of a custom-built single-phase induction motor model on a given distribution feeder.

The motors were subjected to voltage disturbances seen in feeders experiencing the fault-induced delayed voltage recovery (FIDVR) phenomenon. To study the FIDVR phenomenon, a range of voltage depressions were simulated for predetermined system conditions.

A surge current entering into the cables might cause severe damage to them. Therefore it is necessary to investigate surge phenomena of the cable from the surge propagation point of view. An FDTD method (Finite Difference Time Domain) has recently been applied to analyze this kind of surge phenomena. Accordingly, we have adopted a VSTL rev. (Virtual Surge Test Lab. rev.) which is a surge analysis program developed by CRIEPI (Central Research Institute of Electric Power Industry) in Japan to carry out surge simulation. In this paper, we first discuss the comparison results of surge experiment results by means of a co-axial cable (Type RG58 A/U) and of simulations by means of VSTL rev. Secondly, we illustrate surge phenomena that have arisen on a co-axial cable which is connected with a transmission line through a cable junction.
