One potential application is the integration with the railway infrastructures as a new green technology. This goal will be achieved by proposing heuristic technique to enable interconnected MGs to work transparently with the recent energy storage. Railway transportation MG model is proposed to balance energy flows between trains moving and braking energy, energy storage system and a main power utility network. The paper proposes an energy optimization tool for the interconnected railway-MG system. Artificial Bee Colony Algorithm (ABC) is applied for achieving the economical cost during the operation. Digital simulation scenario has been validated by real data; the achieved results show the impact and effectiveness of the proposed strategies.","PeriodicalId":222683,"journal":{"name":"2016 IEEE Smart Energy Grid Engineering (SEGE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134614387","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}

In V2G, there are numerous challenges among which cyber security is a major one that needs to be addressed with priority. The software-defined networking is an advanced architecture for next generation networks, which provide flexible control by separating control plane from data plane. The flexible configuration for the communications and security can enable more scalable, secure, and collaborative system, these make the SDN as a potential communication architecture for V2G. This paper aims to apply the SDN technology on V2G system, which we termed as software-definedV2G (SD-V2G). To the best of our knowledge, this is the first work to deal with the high dynamics of communications and security for V2G by using SDN. Moreover, we propose a novel security communication mechanism (SCM) for dynamic V2G system to ensure confidentiality, integrality, non-repudiation, authentication, etc. To evaluate the scheme, the security analysis, performances, and comparisons are done to demonstrate that the proposed software-defined SCM (SD-SCM) is possible and a promising solution for SD-V2G system. The proposed SD-SCM is significant to enhance the security for V2G.","PeriodicalId":222683,"journal":{"name":"2016 IEEE Smart Energy Grid Engineering (SEGE)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117340915","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 includes the poor efficiency of gas and oil heaters, the high installation effort for connecting the central heating as well as low heat-transfer rates. Investigations point out that warm ambient surfaces increase the physical living comfort without heating up the air inside rooms while reducing costs. These conditions can be achieved by radiation heating where heat is not stored in the air and thus not lost in case of ventilation. In this paper, a new approach will be described, where radiation heating is applied to a variety of surfaces of domestic objects by a new technology. This technology offers new opportunities in contrast to commercial systems of radiation heating, which are largely applied on planar walls. Furthermore, it will be outlined how this technology can be used for radiation heating on desks, so anyone can adjust its own feel-good temperature in the office. A concept that allows providing heat exactly where it is required, e.g. in the proximity of a person, is developed.","PeriodicalId":222683,"journal":{"name":"2016 IEEE Smart Energy Grid Engineering (SEGE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127049344","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}

Despite having this issue, there are also certain benefits which are shown by opposing with another concentrated winding design that has a higher fundamental winding factor.

In car, a 12V Lead-acid storage battery is used to operate air conditioner, main lights and various actuators in engine control unit etc. Before the lead-acid battery ends up all the discharge, it should be charged using the alternator. In order to improve fuel efficiency, it is necessary to implement a so-called charge control, where the battery charge is executed in deceleration period avoiding the acceleration period of the car. In Hybrid cars, as a high voltage NiMH battery is equipped, it is possible to charge 12V Lead-acid storage battery from the high voltage battery. By using this scheme, it is realized not only to take off the alternator but also to improve braking touch for the car driver, because all regenerative energy can be absorbed in the high voltage battery. Furthermore the fuel efficiency can be improved easily for the reason why the efficiency of DC/DC converter is much higher than that of alternator.","PeriodicalId":222683,"journal":{"name":"2016 IEEE Smart Energy Grid Engineering (SEGE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122891745","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}

Given the increasing number of remotely located large power offshore wind farms, power sharing control and voltage regulation are significant challenges in the development of large multi-terminal voltage source converter high-voltage direct current (MT VSC-HVDC) transmission grids. Additionally, a wind-power curtailment algorithm is needed in cases of high windpower generation during low power demand from onshore AC networks. This work presents a power sharing control and wind power curtailment algorithm. This algorithm is based on selecting the optimal droop parameters of the power receiving converters and the reference power output for the offshore wind farms to share the offshore wind energy to the MT HVDC network among different AC grids based on desired shares. These desired power shares are defined to fulfill the active power requirements of the connected systems to achieve their objectives.","PeriodicalId":222683,"journal":{"name":"2016 IEEE Smart Energy Grid Engineering (SEGE)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128898986","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}
