According to the data requirement of various simulation algorithms, the modeling of hierarchical architecture and charging/discharging behavior of EV is performed on the built platform to describe the temporal-spatial distribution of charging load of large-scale EV in a wide range, and based on the proposed model a unified interface for simulation algorithms is established. The built platform can be used to simulate and verify both the predictive algorithm for charging load of large-scale EV and the control algorithm for the coordinated charging, thus it provides the possibility to compare the effects of different algorithms. In terms of simulation, the problem that the effects of the predictive and control algorithms given by reference literatures are hard to be verified by experiments due to the smaller development scale of EV at present can be well solved. The functions and the effectiveness of the built platform are shown by analysis of examples.","PeriodicalId":20420,"journal":{"name":"Power system technology","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66320659","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}

A supercapacitor-battery hybrid storage system is proposed to balance the wind power and planned export power of the wind farm. Firstly, using empirical mode decomposition(EMD), the difference between planned export power and the original wind power(unbalanced power, UP) is analyzed to obtain the intrinsic mode functions(IMFs). Secondly, a mathematic method is then developed to confirm a so-called gap frequency to decompose the unbalanced power into high and low frequency components based on the concept of minimum overlap energy. Unbalanced power smoothing is then achieved by dispatching the powers of supercapatiors and batteries to compensate the high- and low-frequency IMFs according to the characteristics of supercapacitor and batteries respectively. Finally, based on a set of data acquired from an existing wind farm, a hybrid storage system(HSS) is designed aiming at minimizing the capital cost and also can make wind power approach the planned export power of the wind farm in a great extent, numerical analysis verifies the efficiency of the developed method.","PeriodicalId":20420,"journal":{"name":"Power system technology","volume":"39 1","pages":"2107-2114"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66320406","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}

Since the simple proportional integral differential(PID) controller or proportional integral(PI) controller are generally applied in actual wind power generation projects to achieve the control objective to output constant power and it does not come down to complex intelligent control algorithm, in the occasion that the wind speed is higher than rated wind speed an additive decomposition based method is proposed to normalize the design parameter of variable pitch controller for wind power generating units, that is, the variable pitch control problem of wind power generating unit is decomposed into two simple subproblems, namely the tracing of linear time-invariant main system and the stabilization of auxiliary system. Based on the proposed principle, a simple PI controller is designed, and the optimization design of the controller is carried out, and then the stability of this controller is proved by theoretical derivation. Finally, the fact that using the optimized controller the stationary of the output power can be greatly enhanced is validated by simulation results.","PeriodicalId":20420,"journal":{"name":"Power system technology","volume":"38 1","pages":"3436-3440"},"PeriodicalIF":0.0,"publicationDate":"2014-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66320653","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}
