This paper presents the performance enhancement of a non conventional energy system (NCE) based microgrid for the seamless grid synchronization. This paper presents dynamic controls for grid connected and islanded modes of operation. For grid connected mode (GCM), a quadrature third order generalized integrator and frequency locked loop and multilayer harmonic decoupling network (QTOGI-FLL-MHDN) based control algorithm is used. The problems like voltage imbalance, DC offset, swell/sag, fluctuation in power produced by WECS, are successfully taken care by QTOGI-FLL-MHDN. The quadrature component of load fundamental is extracted with QTOGI-FLL-MHDN. For standalone mode (SAM), a resonant and proportional resonant (R+PR) control is presented. For the synchronization technique to perfectly track the phase and frequency, a dual TOGI (DTOGI) is combining with the phase locked loop (PLL). This improves the system response under frequency deviation. During frequency variation, it effectively follows the voltages of the grid and the load and it is adjustable to different conditions of grid. Total harmonic distortions (THDs) of are in the boundaries of the IEEE-519 standard.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134183597","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 contained higher order harmonics which generates electromagnetic induction which in turn causes heating of the core of power transformers or distribution transformers. Simple pulse width modulation based inverters which uses MOSFET/IGBT has high switching loss, and it has quite low reliability and the power handling capability in comparison to using thyristor/SCR. In case of thyristor-based inverters, pulse width modulation in not feasible due to commutation circuits. In dc to ac conversion, it is desired that the output waveform resembles a sine wave as much as possible and harmonic content must be low. In this paper, a multilevel inverter topology has been presented in which switching angle has been controlled and three phase ac to dc converter circuits are used in inversion mode. Since there is natural commutation, there is no requirement of a separate circuit for synchronization. In this paper, simulation is performed for grid tied three-phase 12 pulse converters. The solar PV systems are incorporated for DC source. The converter is analyzed by varying DC source voltage, Inductance and varying the switching angles so that the total harmonic distortion is reduced.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132679558","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}

DC-DC converter is completely avoided, voltage stabilization, maximum power point tracking and DC to AC conversion are done through only multilevel inverter. Five level multilevel inverter with five switches is developed and further to increase each two levels in the output voltage waveform only one more additional switch is to be added. The $1-Phi$ multilevel inverter output is integrated with the $1-Phi$, 230V, 50 Hz supply from the grid. Shunt active current controller is designed to ensure that only real power flow exist in the system. The output voltage total harmonic distortion obtained is only 1.18% till $100^{mathrm{t}mathrm{h}}$ harmonic content, which is very less and multi carrier sinusoidal pulse width modulation control scheme is used to control inverter. The simulation results are validated with the practical per day energy generated through grid connected conventional inverter.

The proposed VBTI topology is developed by integrating the coupled inductor based high voltage gain DC to DC converter and two-level inverter. Due to the presence of high voltage gain feature, the VBTI topology can pump power from a lower DC voltage PV source in to the grid/load without using higher duties. Another important feature of VBTI is that it completely eliminate /suppress leakage current due to a common connection is shared between the negative terminal of PV source and grid neutral. In addition to that, the VBTI topology comprises only six controllable power switches to control the inverter which increases the reliability and decreases the cost of the system. Further, a simple level-shifted modulation strategy is introduced to control the VBTI. The design of the various power components of the VBTI and its main operating modes are discussed in detail. Further, the maximum efficiency of the VBTI assessed to be $approx 95$%. The proposed VBTI topology is verified through MATLAB simulations for a 400VA grid-connected system. All the main results are presented in this paper. The experimental work for the PV fed grid-connected VBTI topology is underway.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132460662","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}

This means that in a switching cycle the peak to peak (P-to-P)CMV and the value at which transition of CMV happens have lower magnitudes for a multilevel inverter (MLI) compared to a 2-level inverter. This is an important advantage but still does not justify the use of MLIs on account of economic and component count factors. To offset this limitation, this paper proposes a modified 2-level three-phase inverter which exhibits similar reduced CMV performance as does a 3-level inverter. The proposed inverter uses only two extra switches, which makes the total number of switches as 8. The two extra switches allow one of the inverter legs (out of 3) to function as a 3-level inverter leg, while the other 2 legs continue to work as 2-level inverter legs. This results in a unique space vector (SV) diagram with 12 SVs whereas a traditional 2-level inverter has only 8 SVs. It is shown that by appropriately using these 12 SVs a similar CMV performance of a 3-level inverter can be achieved using the proposed topology. Simulation studies are carried out using the PLECS software to validate the various claims.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115277166","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}
