Under the current operation mode, the next-day network load flow is based on the wind power forecast. Because of the inevitable forecast errors in wind generation, the wind power probability distribution would always be given. Considering the acceptable capacity of power grid, the wind power is fitted to distribute irregularly. The irregular distribution input does not satisfy the demand of classical numerical probabilistic load flow calculation. This paper proposes a probabilistic load flow calculation method based on proportional allocation principle and Latin hypercube sampling, which ensures high calculation precision and improves the speed dramatically. The veracity and validity of the method proposed is tested in the IEEE 118-bus system. The irregular probability distribution of wind power is fitted under the restriction of tie line and the simulation results show that the method proposed also has excellent practical value.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"24 1","pages":"1457-1461"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90492359","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}

Firstly, the mathematical model of three-phase three-level VIENNA rectifier and three-phase two-level inverter were established respectively. The multiloop control method was realized based on the DQ coordinates, and a simplified three-level space vector pulse width modulation method which could simplify the calculation was proposed for the VIENNA rectifier. A composite control method of PI control and synchronous-frame repetitive control strategy was proposed to improve the quality of output inverter waveform. In order to improve the dynamic response of DC-bus, a power forward control strategy was proposed for the whole system. The whole system keeps unit power factor in the input side and pure sine voltage in the output side. The modulation and control method of three-phase three-level UPS was implemented in one DSP(digital signal processor). Experimental results of the 200kVA UPS system show that the proposed modulation and control method was correct and effective.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"32 1","pages":"1088-1092"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83087141","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}

This paper designs a kind of six-module-cascaded MMC-BDC applied to mass rail transit. Based on carrier phase-shifted (CPS) modulation, a dual-loop control strategy consisting of a common current loop and an individual voltage loop is proposed. It is able to realize both bidirectional power flow and real time voltage balancing online. Regarding the designing of this strategy, this paper reveals a series of contradictions that needs to be properly compromised, e.g. large voltage loop gain results in large inductor ripple current, which means more power losses, while smaller gain leads to long voltage balancing time. And it's found that the ripple current is larger in unbalancing mode than that of in balancing one, which is important for the parameters choice. The design method to trade off the contradictions was given and the dual-loop control strategy was successfully implemented. Analysis and simulation waveforms verify the correctness and the effectiveness.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"21 1","pages":"59-63"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83268379","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}

With regard to the uni-directional power flow of the diodes, multi-capacitors are naturally charged in parallel, and discharged in series. Thus, high voltage gain is achieved without extreme large duty ratio of power devices. Furthermore, it does not increase the complexity of control circuit due to only one fully controllable power device. However, a lot of passive components increase the order of system model and complexity. This paper proposes a new modeling approach to get the reduced model for high voltage gain DC-DC converter with multi-cell diode-capacitor network. Then, the linear closed-loop controller is designed based on the reduced model in frequency domain. Finally, simulation and experiment are implemented to verify the correctness and effectiveness of the reduced-order modeling approach. And it contributes to the simplification of controller system, which is very promising in high voltage gain DC-DC converter with multi-cell diode-capacitor/inductor network in the renewable energy application.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"103 1","pages":"3066-3072"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80819978","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 nonlinear disturbance observer (NDO) only with local information is designed firstly to track power disturbances caused by load changing or the volatility of the renewable sources in the dc microgrid. With the observer, voltage droop method has been adopted in achieving power sharing and autonomous operation of a dc microgrid. Furthermore, an improved current feedforward is developed to suppress wide fluctuations of the dc bus voltage during transients. In addition, a notch filter has been used to effectively eliminate the second harmonic ripple components in the inductor currents of the droop control units to improve the power quality. The effectiveness of the proposed control scheme is verified on a laboratory prototype including two bidirectional dc-dc converters supplied by two programmable dc power supply systems, a dc load with a resistor connected to the dc bus via a buck type dc-dc converter and a three-phase unbalanced ac load.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"248 1","pages":"3708-3714"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80644671","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}
