An MPCC method of permanent magnet synchronous motor (PMSM) based on the simultaneous optimization of voltage vector and duty cycle is proposed in this paper. In the proposed MPCC method, the duration of every active-vector is calculated based on the principle of deadbeat q-axis current control firstly. Then, both voltage vector and voltage vector duration are optimized simultaneously in the cost function. Simulation results show that, compared to the traditional duty cycle MPCC, the proposed MPCC method achieve lower current ripples and less current harmonics.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"35 1","pages":"881-884"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85703890","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}

When the inverter is operated under the current-mode grid-connected power generation, the feed-forward control of grid voltage is employed, which can improve the dynamic performance of the inverter and suppress the current impacting to the grid. And when the inverter is in the voltage-mode stand-alone operation, the feed-forward control of off-grid voltage reference is adopted to reduce the switching delay and to restrain the impact of the electricity. With the synchronous switching of the mode switch and the selection switch to select the corresponding feed-forward, the switching of the inverter at any time in double operation modes can be easily realized. Experiments show that the method of feed-forward control in this paper can realize the smooth switching of the inverter in the double operation mode of stand-alone operation and grid-connected operation.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"87 12 1","pages":"920-923"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84032268","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 this paper, an improved droop control strategy based on three-phase independent control is proposed. In this method, the independent droop control curve of each phase is formed by considering three-phase active power, reactive power and voltage respectively. The influence of unbalanced impedance parameters of energy storage system can be eliminated by fine-tuning each independent droop coefficient. The voltage and current imbalance can be solved by adjusting the secondary regulation value of each phase independently. A simulation model and experimental system are set up to verify the feasibility of the algorithm. The results show that the control strategy can improve the power quality of micro-grid with good stability in the unbalanced three-phase system.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"188 1","pages":"2639-2643"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78527362","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}

It shows the characteristic of resistance and inductance in low frequency band and has good effect of harmonic suppression. It shows the resistance characteristics in high frequency band and suppresses the harmonic amplification. A improved LCL filter is designed based on virtual harmonic impedance control method. The improved method is LC resonance branch paralleled on damping branch and provides low resistance pathway for the harmonic current near carrier frequency.

Energy storage system is of great value due to its quick and accurate response. Regulation service plays an important role in real-time balance. A novel regulation market bidding model is proposed in this paper, with quoted price, regulation performance taken into consideration. Unlike traditional clearing model, up-regulation capacity and down-regulation capacity are differentiated. The regulation performance indices, including accuracy, response time and ramp rate are used to modify the quoted price. Then the clearing model is formulated to minimize the regulation service cost with different regulation requirements satisfied. As for the payments, in reference to two-part payment, on one hand, all the selected regulation resources are paid for the reserve capacity, on the other hand, they can also be paid according to their actual effective power regulation. The numerical example demonstrates that clearing results vary as different regulation performance demands occur. When high quality regulation is needed, high quality resources like energy storage system are of great advantage. It turns out an effective incentive method for resources of good regulation performance like energy storage system to participate in regulation market competition.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"28 1","pages":"2644-2649"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77073102","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}

Each VSC transmits information by changing the control parameters, and receives information by observing the local output power. By using common coding schemes, which transform the DC MGs in some familiar communication channels, some important communication challenges can be addressed, such as random load variations and VSCs switching, as it do not need a separate communication channel. For this purpose, two multiple access strategies are analyzed and the method based on training sequences is presented in this paper.
