Confronting this important problem of the power system safe operation, it is really top urgent to build a feasible solution to develop the large-scale new energy. Therefore, this paper raises a distributed generation system (DGS) based on various renewable energy resources, adopting a small-sized combined generation equipments of unit capacity 100kW max with wind, solar and biogas energies, and super capacitor and battery storage devices, which builds and installs near to the local loads center to supply it optimally in stable and safe, high reliability and less feeder loss mode. The operation performance of the demonstration project shows: the DGS based on various renewable energy resources is an effective and feasible approach for its large-scale and efficient utilization purpose because of its particular distribution characteristics, direct power supply to the local loads and its little influence to the grid.","PeriodicalId":288978,"journal":{"name":"2011 4th International Conference on Power Electronics Systems and Applications","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127124302","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}

Based on the dynamic model of vehicle power train, the shifting process without clutch operation is studied. The off-line simulation model of the DCM system is built with Matlab/Simulink. Through offline simulation, the up shifting process and down shifting process of AMT are simulated. And the shifting time of various stages of shifting process is discussed. The off-line simulation results indicated that the shifting strategy without clutch operation is better than the active synchronization control strategy of motor.
