The performance of the DVR depends on its controller. Therefore, in this method, two controllers are proposed in the stationary and synchronous reference frame for DVR voltage regulation. A proportional-resonant (PR) controller is first designed in stationary frame. A proportional-integral (PI) controller is then proposed in the synchronous reference frame. The performance comparison of these two controllers in both transient and steady state responses are also carried out in this paper. With the proposed control method, the DVR can compensate for the FRT, while the DFIG wind turbine can continue its normal operation as demanded in actual grid codes. Simulation results using Psim simulation program are expressed for a 2 MW DFIG and a DVR system to validate the effectiveness of the proposed control methods during the FRT.","PeriodicalId":236136,"journal":{"name":"Proceedings of The 7th International Power Electronics and Motion Control Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126438207","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}

The proposed strategy is based on the droop control technique, which only using the local measurable feedback information. This approach can be applied to the inverter-based microgrids where communication wires are not economic and reliable due to the distant physical locations. Unfortunately, the trade-off has to be made between the transient response and the power sharing accuracy for the conventional voltage and frequency droop control method. Moreover, the output and line impedance of the inverter presents a great impact on the power sharing accuracy. The proposed method takes into account the resistance of inverter output impedance and line impedance, and uses the active and reactive output current as the control variables, which limits the current spikes during the initial and transient states. Additionally, the derivate-integral terms are introduced to enhance the dynamic response of the inverters. Simulation results and experimental waveforms are given to validate the proposed control strategy.","PeriodicalId":236136,"journal":{"name":"Proceedings of The 7th International Power Electronics and Motion Control Conference","volume":"10 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121300426","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}

The ZSCCs are suppressed well and the discrepancy and distortion of currents are overcome. Therefore, the reliability and efficiency of the system are improved.

A control strategy of voltage and frequency based on battery is proposed in this paper which purposed on regulating an islanded microgrid containing kinds of distributed generators (DG). According to the problem of traditional droop control of V/F that does not take into account of load structural changes, the control of battery introduces the voltage and current feedforward based on traditional V/F control strategy. Considering the variation of structure and parameter of the load is more suitable for practical power system.

It can reduce the active power from the grid by injecting active power from the PV generators into the grid. The reactive power and harmonic compensation ability of the CGCI leads to reduced root-mean-square (RMS) value of source current and thus reduced residential power loss. The proposed CGCI and conventional inductive-coupled grid-connected inverter (IGCI) are compared. Results indicate that CGCI can achieve the required power delivery with lower inverter voltage rating. The proposed CGCI is utilized to integrate a PV generation system to the grid. Besides, reactive power and harmonic compensation is achieved simultaneously when the active power is injected. A dynamic reactive power adjustment block is added to the control system of the CGCI, which can improve its performance when the required reactive power compensation exceeds its control capability.
