For balancing the dc-link capacitor voltages and the flying capacitor (FC) voltage of ANPCI, a voltage balancing algorithm has been implemented which results in negligible voltage ripple for FC. However, voltage ripple in dc-link capacitors is still significant and to minimize it further, an external chopper circuit is employed at the dc-link of the ANPCI. To regulate the chopper inductor current, it is proposed to use average current control technique for the chopper integrated ANPCI. The average current controller operating in CCM is implemented along with the capacitor voltage balancing algorithm and it produces less ripple in the capacitor voltages compared to the discontinuous conduction mode techniques. Also, the chopper current becomes a nearly sinusoidal waveform. Finally, the ANPCI and chopper integrated ANPCI are implemented in hardware and their performance is compared.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125016561","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, we established an effective model to analyze the dynamic characteristics of multiple VSMs under any disturbance. Considering that the active and reactive power loops are decoupled, the model developed for the active power and frequency control loop of VSMs is equivalent to a two-terminal network that includes the first (parallel) and second (series) \"admittance.\" The active power and angular frequency increments were analogized as the current and voltage of the circuit network. An extended two-terminal network model of the multiple-VSM parallel system was established to comprehensively and accurately depict the response of the output active power and angular frequency under disturbances of the load and active power reference. The key active power– frequency response characteristics of the multiple-VSM parallel system were deduced. The effectiveness of the proposed extended model was verified through simulations and experiments. The results indicated the suitability of the proposed model for active power–frequency response analyses of multiple-VSM parallel systems. Furthermore, the experimental results obtained under different modes agree with the theoretical analysis results, thereby validating the key conclusions.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125054107","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}

According to the particle separation model and distribution experiments, the main influencing factors of particle collection performance and the requirements for ESP supply are proposed and verified. By analyzing the static characteristics of the ESP supply with three typical modulation schemes, the loss reduction of IGBT bridges and power transformer are achieved with a lower cost, and the supply reliability is improved. Compensation network enhances the dynamic stability and response speed of the designed supply and guarantees the ESP collection efficiency even in the worst operating condition. Moreover, an ac resistance optimization method applicable for transformer windings is proposed. Compared with conventional design methods, the number of layers of the windings is treated as a design variable instead of as a predetermined parameter, and the core window dimension and insulation requirements are introduced as boundary conditions. The experimental results verify that the design of the power transformer and ESP supply is reasonable, and the field operation data indicate that the pollutant emission of the precipitators powered the devised high-voltage dc supply satisfy the strictest standards in China and the European Union.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125089544","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}

For successful operation of parallel WT-based energy conversion systems, a well-regulated voltage is needed at the collection point. Due to wind speed variation, the generated voltage from each WT may differ from one to another. Conventional solutions use regulating converters with full power rating. In this paper, a new concept is presented which depends on using fully-rated uncontrolled rectifier bridges for AC-DC conversion, and partially-rated fully-controlled bridge rectifiers which are used as voltage tuners to guarantee the flow of desired maximum power point DC currents through the parallel connected branches. The proposed system is simple, cost effective, reliable and efficient. The main drawback of the proposed system is the critical need for filters and VAR compensators on the AC side to ensure acceptable performance of the WT generator. Also, smoothing reactors are needed on the DC side for filtering of the transmitted DC current. A simulation model has been built to validate the proposed concept, and the simulation results show the effectiveness of the approach.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125856178","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 context, a Multi-port Autonomous Reconfigurable Solar (MARS) plant that integrates PV and ESS to alternating current transmission grid and high-voltage direct current (HVdc) link is studied in this paper. With penetration of power electronic based resources in the grid, the grid’s capability to recover from frequency or voltage disturbances are reduced. Therefore, one of the vital objectives of any new grid integrated power electronic resource is to provide advanced control functions like voltage and frequency support to the grid during disturbances. In this research work, a detailed implementation of a synchronverter-based control algorithm of MARS is presented. The proposed control algorithm and the MARS control architecture are evaluated through simulations on PSCAD/EMTDC simulation platform to showcase the performance in different operating conditions. In addition, they are evaluated in Opal-RT offline simulation models which can also be used to perform control-hardware-in-the-loop (cHIL) tests.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126136814","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}

Compared to the topology with two wound stators, the studied one has a smaller total axial length and is expected more suitable for applications where the space is limited in axial direction. Both topologies are optimized through 3-dimensional (3D) finite element analysis (FEA) by the combined design of experiments (DOE) based sensitivity analysis and surrogate-assisted multiobjective differential evolution (DE) algorithm. Key factors affecting the two objectives, i.e., total active material cost and total electromagnetic loss, are identified.
