Because of this, there are growing concerns on cyber security issues that brought by these technologies. It was noted that attention has been drawn to the security framework for engineering applications/systems and their own local area network (LAN), but the security and reliability of the communication channels for supporting these applications/system have been taken for granted.

Owing to the higher-phase topology, better fault-tolerability and higher power density can be achieved. On the other hand, higher-phase machine suffers from the problem of relatively lower cost-effectiveness. Hence, trade-off between different criteria should be considered to fulfill various situations. In particular, all the PS-FSPM machines are highly favorable for the electric vehicle applications, while all of their key performances are analyzed with the support of the finite element method.","PeriodicalId":150994,"journal":{"name":"Journal of International Council on Electrical Engineering","volume":"291-294 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124031697","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 characteristic of VSWT-PMSG is that the wind turbine and the power system are interconnected by back-to-back converter. For this reason, PMSG doesn’t synchronize to grid side. In a conventional control strategy, network disturbance impacts propagate DC link, and a capacitor and a parallel protection resistance in it are deteriorated. In this paper, new control strategy of generator side converter is proposed in order to realize that a network disturbance impact propagates PMSG. As a result, elements in DC link don’t absorb a network disturbance impact fully and thus quality reduction becomes slower. In this paper, such control strategy for converters is given as a basic study and it is referred as ‘defensive control’.","PeriodicalId":150994,"journal":{"name":"Journal of International Council on Electrical Engineering","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116597815","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}

Meanwhile, few new steam power plants and transmission lines are being constructed because of the environmental problems they cause. As an alternative, small-scale independent power systems with energy-storage systems such as microgrids are increasing. In a small microgrid system that is vulnerable to frequency variation, coordinating an optimized scheduling between the energy-storage system and renewable energy generation is important. However, considering the uncertainty of weather forecasting and uneven load patterns, several cases should be considered. In this paper, the operation algorithm of a stable PV/BESS system is proposed. This system contributes helps decide the output battery to design battery capacity as a contingency for unexpected situations in a microgrid system.","PeriodicalId":150994,"journal":{"name":"Journal of International Council on Electrical Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116497187","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}

Until now, the various copper wires have generally been adopted in WPT system. From this reason, the transfer efficiency is limited since the copper wire keeps low Q intrinsically. On the other hand, as superconducting wires keep larger current density and higher Q value, the superconducting resonance coil can be expected as a reasonable option to deliver large transfer power as well as improve the transfer ratio since it exchanges energy at a much higher rate and keeps stronger magnetic fields out.

Since they are proportional to the direct and the quadrature components of the transferred current, Id and Iq, respectively, the power management is realized by regulating the two current components. An observer is designed to estimate them from the feedback voltage and the average absolute value of the transferred current. Since all the feedback signals for the observer are DC quantities, the sampling speed is not necessary to be very high. A digital controller is then synthesized to regulate Id and Iq at desired values. In the control system, the bridge shift angle is used to handle Iq, meanwhile the switching frequency is variable to manipulate Id. The current command for Id is calculated from the desired active power, meanwhile, by assigning a positive value for Iq control loop, soft turn on is easily achieved.
