Combined with the characteristic that vehicles are mobile, EVs can provide a natural energy transmission system called EV energy network. This paper analyzes the features of energy routes in the EV energy network and studies the impact of traffic congestion on the EV energy distribution networks. Based on the characteristics of traffic congestion in the urban, sporadic congestion algorithm and recurring congestion algorithm are presented to simulate in a model of the EV energy network. Additionally, energy degree (ED) and energy source available rate (ESAR) are defined to reflect the current state of the EV energy network. The real-world transporting data in Manhattan and Pioneer Valley Transit Authority (PVTA) is utilized to analyze the robustness of the proposed EV energy network.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"26 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":"130798719","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}

WPFS) depends on many field situations, such as geographical conditions, the quality of numerical weather prediction (abbr. NWP), and historical data acquisition. The forecast models and their specifications differ case by case. It is necessary to provide any efficient methodology to design an adaptive WPFS. This paper analyzes, evaluates and then handles the affecting factors, including the space and temporal limitation of NWP, the misplacement error of grid point forecasts and the regression of wind power output model. A systematical solution which is independent on forecasting models is then proposed and verified to improve the adaptability of WPFS that consists of pre-processing of input data, setup of wind power output model and forecast error evaluation.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"102 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":"131221743","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}

There are significant benefits for utilities and manufacturers that can be achieved through the standardization of these devices. In turn, this would facilitate the deployment of smart distribution applications (SDA). The sensor-controller pair is the foundation upon which Smart Grid applications are built. Standardization, interoperability, and interchangeability of different controllers and the way they connect to the system are integral to realization of the Smart Distribution Vision. This paper describes an initiative aimed at the development of a generic technical specification of a standardized universal controller, based on a modular concept.

This paper presents a hybrid simulation method for real-time operation of EVs, charging stations, traffic and the grid. It first describes the traffic model and electric model and builds a hybrid model for EVs to combine these two models. The paper presents a detailed timing simulation method afterwards. After generating EV inflows and traffic flows in different places and setting EV's charging behavior, EVs' State of Charge (SOC) and spatial moving and charging stations' working states can be viewed through simulation. An example is presented to illustrate the impact of EV inflows on the charging power of charging stations. This method can be applied in other researches, and it will be utilized for future research work on the interaction between power grid and traffic network.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"15 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":"133417347","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}

It will be shown that the main effects that determine the degradation or improvement of mode damping due to wind power generation lies in the alteration of the operating points of the involved synchronous generators and the nature of the oscillatory modes affected. It is also analyzed the effect of reactive power exchange between wind farms and the power grid on oscillatory behaviour. Such developments are validated by performing simulations on a 2017 peak scenario for the Uruguayan transmission system, which shows a strong interaction between the pre-existent hydro power plants and future wind farms to be incorporated1.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"43 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":"132763696","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 intermittent nature of PV energy and quick fluctuations of load demanding require energy storage units (ESU) which generally consists of storage battery and supercapacitor (SC). The development of coordinated control tools for next-generation PV installations, along with ESU, provides flexibility to distribution system operators. The objective of the control of this hybrid PV and energy storage system is to supply the desired active and reactive power to the grid and at the same time to maintain the stability of the dc-link voltage of the PV and energy storage system through coordinated control of power electronic converters. This paper investigates three different coordinated control structures and approaches for grid integration of PV array, battery storage, and SC. A computational experiment system is developed by using SimPowerSystems and Opal-RT real-time simulation technology. The performance of the coordinated control techniques is evaluated.","PeriodicalId":433870,"journal":{"name":"2013 IEEE Power & Energy Society General Meeting","volume":"1 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":"128824834","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}
