These filters attenuate high order harmonics effectively; however, the grid impedance fluctuations (GIFs) may cause resonance and system instability. The GIF can reduce the resonance frequency to lower than a permissible threshold, then, the resonance may happen and prevent some nonlinear loads from being fed. On the other hand, very high resonance frequencies cause capacitor of the filter being actually short circuited. Consequently, the nature of the filter changes and reduces the power quality of the network. In this paper, considering the possible range for GIFs and using Kharitonov control theorem (KCT), the coefficients of the PI controller and the current feedback of the filter capacitor are obtained simultaneously to ensure safe and desired operation of the GC-VSI against the GIFs. As a result, the proposed closed loop system shows optimal response to variation of the reference current. Genetic algorithm (GA) is used to determine optimal values of the coefficients and the gain. Simulation results carried out in MATLAB/SIMULINK show accuracy and effectiveness of the proposed method.","PeriodicalId":296229,"journal":{"name":"2019 10th International Power Electronics, Drive Systems and Technologies Conference (PEDSTC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121918689","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 BLDC motor is employed to drive a centrifugal pump coupled to its shaft due to merits of high efficiency and compact size of this drive. This system utilizes a Buck-Boost converter as an interface DC-DC converter between the solar photovoltaic array and the inverter of BLDC motor drive. The application of direct torque control strategy to BLDC drives has been investigated. In this control method for BLDC drive, direct control of stator flux and electromagnetic torque, and attainment rapid torque response and the high efficiency is possible by choosing the efficient modes of switching inverter to confine flux and torque error in a proper hysteresis band. MATLAB software is used to analysis, design and control of this system and represent the performance of transient and steady state response of SPV array powered Buck-Boost converter fed BLDC driven water pumping system. Simulated results are displayed, and it is shown that, compared with conventional hysteresis and PWM current control, the BFO-PI strategy results in reduced current and torque ripple, robust performance, faster dynamic response and lower steady state error under different mode operation.","PeriodicalId":296229,"journal":{"name":"2019 10th International Power Electronics, Drive Systems and Technologies Conference (PEDSTC)","volume":"86 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126282912","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 these systems, the inverter is the only converter where both maximum power point tracking algorithm and grid side controller will be applied to it. Hence, the MPPT algorithm should be adapted with grid side controller for better transient response and to remove the internal control loops. One of the most popular MPPT algorithms and grid side controllers are P&O and direct power control, relatively. To combine them, an P&O with power output should be used. However, the response speed of controllers especially in single-stage system is very important. Therefore, since the dynamic of power is less than current or voltage, a fast P&O algorithm with power output is beneficial to exceed the transient response of the converter. Hence, a changing step-size P&O algorithm with power output is proposed in this paper. This controller regulates the power perturbation automatically, where the response speed of the system, power oscillations and accuracy in steady state can effectively improve. In addition, to reduce the hardware cost and size, a sensorless method is also presented for grid side controller.","PeriodicalId":296229,"journal":{"name":"2019 10th International Power Electronics, Drive Systems and Technologies Conference (PEDSTC)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125765769","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}
