On the contrary, many loads have equipped with power conversion circuits in front to improve the operational efficiency, e.g. air conditioners and LED lighting, which in fact can also provide the regulation function for stabilizing grid during transient process. This paper therefore proposes a ramp control theory for insensitive active power electronics loads in microgrid to control grid frequency together with DGs. The load ramp control method can effectively reduce the frequency variation especially when microgrid enters islanding mode from grid-tied mode, meanwhile the ramp control can release the burden of fast energy storage systems in microgrid and then reduce the construction cost of microgrid. Control wise, load ramp control is also a communication-less control theory, which only assumes the local information. Matlab simulations and experimental results are presented to show the effectiveness of the proposed theory in islanding microgrid.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"86 1","pages":"2348-2354"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83756889","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 order to eliminate the bulky MV step-up transformers in MVAC grid, the use of a MV step-up DC/DC converter in MVDC grid is an attractive alternative. In this paper, two modular MV step-up DC/DC converter topologies that combine multiple modules of step-up resonant circuits and high frequency high gain rectifiers are proposed for MVDC grid in wind energy system. Due to the combination of multiple step-up resonant circuits and the high gain rectifiers, the proposed converters are able to achieve high voltage gain without using large turns ratio high frequency step-up transformers. In addition, ZVS turn-on ZCS turn-off are achieved on the inverter side switches to minimize the switching losses. The switching frequency is varied to regulate the output medium voltage for different wind speed conditions. The description and the operating principles of the proposed converter are provided in this paper. Results on a 5MW, 3.3kVac/40kV wind turbine system are presented to highlight the merits of this work.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"15 1","pages":"4789-4796"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88710593","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}

He, Zhengming Zhao","doi":"10.1109/ECCE.2015.7310531","DOIUrl":"https://doi.org/10.1109/ECCE.2015.7310531","url":null,"abstract":"DC micro-grids are considered as a friendly way to integrate renewable energy resources as well as distributed energy storage systems. With high penetration of power electronic converters in DC micro-grids, the control strategies of DC micro-grids can be very flexible. However, the line loss is relatively high at the same time. Thus, a proper optimal power flow (OPF) strategy is needed for DC micro-grids to minimize the line loss. Different from OPF for conventional grids, OPF for micro-grids should not require prior knowledge of grid structure and line impedance because power sources and loads may have frequent reconfiguration in grid architecture and the extendibility of the grid needs to be taken highly into consideration. In this paper, a control strategy for OPF in DC micro-grids is proposed. It is based on conventional hierarchical in DC grids with low bandwidth communication. The key point is an improvement in the secondary control strategy. The proposed OPF strategy needs neither knowledge of grid structure nor operating condition. A 400V microgrid simulation model is presented to verify the proposed method.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"2018 1","pages":"6212-6216"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89356831","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}
