First, a Kalman Filter-based network voltage estimator is proposed to obtain voltage responses without communication links in the presence of load disturbances. Then, a voltage optimal controller using MPC (Model Predictive Control) are developed to implement voltage optimal control. The contributions of this paper are demonstrated: (1) The proposed voltage estimator can dynamically obtain network voltage responses just through local voltage and current associated with each DG (Distributed Generator) unit rather than relying on any communication facilities; (2) In contrast to the conventional PI-based voltage control method, the proposed voltage control strategy can implement not only offset-free control for single-bus, but also optimal control for multi-bus. Thus the flexibility and reliability is improved for islanded microgrids due to communication-less operation. The simulations and experimental results are presented to validate the proposed distributed voltage control strategy.","PeriodicalId":393430,"journal":{"name":"2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134146494","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}

Shortcomings associated with the Z-source inverters like discontinuous input current, high voltage stress on capacitors and no common ground point between the dc-source and inverter bridge has been addressed with the development of the quasi-Z-source (qZSI) inverters. This paper proposes design of an improved high voltage gain quasi-Z-source inverter by adopting a combination of switched-capacitor and switched-coupled-inductor (SCL). Use of the coupled-inductor to charge switched-capacitor can effectively enhances the voltage gain and reduces the turns ratio of the coupled-inductor. The proposed SCL-qZSI due to its higher voltage gain, utilizes smaller shoot-through duty ratio and consequently larger modulation index, thus having lower voltage stress on switching devices as compared to the traditional ZSIs and qZSIs. A detailed theoretical analysis of the proposed converter and its comparison with QZSI is given, and followed by simulation and experimental results.","PeriodicalId":393430,"journal":{"name":"2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131717863","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}

If the sampled values have been affected by switching noise from the power circuit, the control stability of the circuit would be disturbed. This paper proposes a noiseless sampling method for both synchronous sampling and multisampling, which can sample a value without being affected by noise. The synchronous sampling method may be affected by noise depending on the duty ratio of the circuit. The noiseless sampling method for synchronous sampling changes the timing of the sampling to a position that is less susceptible to noise. The noiseless sampling method for multisampling does not obtain the data immediately after turn-on and -off switching. The control circuit can avoid switching noise by using noiseless sampling, which leads to a disturbance in the control circuit and enhances the robustness of the circuit when applying the multisampling method. Experimental results are presented to verify that the current control of the proposed sampling methods is not disturbed by noise.","PeriodicalId":393430,"journal":{"name":"2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133582602","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}
