Unfortunately, they cannot be directly used in MMC-HVDC systems since they can result in dc-line voltage ripples and thus deteriorate system performance and stability under unbalanced grid conditions. This paper studies the problem in detail and then proposes corresponding improved circulating current suppressing strategies for MMC-HVDC, in which newly designed zero-sequence circulating current controller is employed. The proposed strategies can effectively eliminate both circulating currents and dc-line voltage ripples for MMC-HVDC systems under balanced and unbalanced grid conditions. Hence, they greatly enhance the fault ride-through capability of MMC-HVDC systems without adding any control cost or the number of controllers. The theoretical analysis and the proposed strategies are both verified by an established MMC-HVDC simulation model in MATLAB/Simulink.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132592557","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 result shows that the indirect prediction method may cause larger error because of abscure mapping relationship between wind speed and wind power, in addition, this paper also researches the influence on prediction accuracy due to the sampling interval. The result shows that the prediction accuracy is higher when the sampling interval is chosen among 5 ~ 15 min, furthermore, the rate of error increasing is more and more faster along with the extension of prediction duration, while the sampling is smaller, so it is necessary to determine the sampling interval by the prediction time scale. The achievement of this paper provides a strongly theoretical support for the model constructing and data sampling of wind power prediction, and also has the guiding significance to the precision improvement of the wind power prediction.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128816252","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}

But the wind turbine generator cannot be treated as a two-state model in a power system with large scale wind power for the randomness and intermittent of wind. However, a simplified equivalent method of wind farm for reliability evaluation is proposed in this paper and used to turn a large scale wind farm that consists of different types and numbers of WTG to just one equivalent generator in the sense of reliability evaluation. The basic parameters in traditional algorithm such as the mean time to failure (MTTF) and the mean time to repair (MTTR) are replaced by the mean time to shake (MTTS) and the equivalent mean time to repair (EMTTR). The validity of the method is proved by the improved RTS79 system. The reliability index like EENS and LOLE are calculated using this equivalent method and its outcome are compared to that using traditional Monte Carlo simulation. This paper provide a new thought to simplify the model of wind turbines group and has some guiding effects on the power system reliability assessment considering large-scale wind power integration.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127655407","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}

Therefore, the impacts of IIDGs on traditional current differential pilot protection is analyzed firstly in this paper. Next, the fault characteristics of IIDG are introduced and the fault model of IIDG is established, in which IIDG is viewed as a current source controlled by the positive-sequence voltage at the point of common coupling. Then, based on the three-phase voltage and current on both sides of line, an improved pilot protection is proposed, which consists of a negative-sequence current differential protection as an auxiliary criterion for the conventional pilot protection. Finally, the effectiveness of the improved protection scheme is verified by a 10kV distribution network with multi-IIDGs established in PSCAD/EMPDC. The simulation results indicate that the proposed protection can effectively reduce or eliminate IIDG's impacts on current differential protection, particularly for an asymmetric fault, under various conditions involving different IIDG's output and fault resistance, thereby improve its reliability significantly.","PeriodicalId":117485,"journal":{"name":"2016 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"445 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115727917","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}
