This PV system is integrated into the grid at the DC bus of the voltage source inverter (VSI). The PV system satisfies the nonlinear load demand at the PCC (Point of Common Coupling) and feeds the excess power to the grid. The control is able to transfer the power even when the system is subjected to adverse grid conditions. The control is able to solve the inherent problems of the most popular controller used, that is, SOGI and its advanced versions. The boost converter is operated using a P&O (Perturb and Observe) algorithm to maintain the peak power point tracing from the solar PV module. Furthermore, the obtained results of a developed model in MATLAB SIMULINK platform are observed to show that the IEEE-519 standard is duly followed under various adverse grid conditions.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114269683","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 newly proposed transient test as a part of qualification given in IEEE-650 is studied in this paper. This is based on the transient incident reported at the NPP of Forsmark, Sweden. The analysis presented here brings out the possible difficulties in carrying out this transient test.

Unlike the conventional MPPT techniques, the reinforcement learning-based MPPT (RL-MPPT) method has advantages of self-learning ability, which is better applicable performance under different weather conditions.

Due to different resonant modes (LLC and LLC-C) and gain characteristics of the proposed converter can provide a wide voltage gain range. Firstly, when operating at the higher voltage gain, it operates in LLC mode taking advantage of zero voltage switching (ZVS) on the converter and zero current switching (ZCS) on the output rectifier. Secondly, over the low voltage gain, the circuit operates automatically in LLC-C mode. This exhibits notch filter function providing infinite impedance (resonant zero point (RZP)), fast wide voltage gain regulation over a limited frequency range with good over-current protection. The proposed bidirectional converter is operating in both LLC and LLC-C modes. The analysis and design of the proposed converter are included in the paper. Additionally, closed-loop frequency modulation control simulation has been carried for charging during regeneration and discharging during motoring mode, which provides constant output voltage even if the input voltage and load are varying over a wide range. Thus, the proposed 1kW converter can inhibit the high conversion efficiency along with wide voltage gain, making the converter suitable for electric vehicle applications.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128315327","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 smart volt/VAR control approach has been introduced to enable the CVR operation. An event-driven realtime control approach has been proposed to check the effectiveness of CVR deployment. The impact of the community energy system (CES) in micro-grid operation and control has been studied by developing an adaptive volt/VAR droop control strategy for micro-grid CES (μCES) controllers. An accurate voltage sensitive load model has been utilized. The simulations have been carried out using a real-time digital simulator (RTDS) for three cases: normal operation, CVR operation, and cloud transient impact under CVR. Voltage fluctuation control under cloud transient has been further studied without controller, with conventional controller and in the presence of μCES controllers. The real-time simulation results validate the proposed control scheme, and results also reveal that CVR could reduce considerable peak power demand in micro-grid operation. Further, the μCES controller scheme handles voltage control smartly in comparison to conventional droop control.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124599748","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 exact small-signal model is developed by using current modulator equations in the state-space model of CI-SIDO buck converter. The current modulator equations define the duty ratios as a function of the circuit variables and are the one that predicts the instability. It is observed that instability in CI-SIDO buck with PCM occurs when both or any one duty ratios are greater than 0.5.

The sliding mode control (SMC) is well known for its robustness and improved dynamics for non-linear systems. Still, it includes the drawback of high-frequency chattering and degradation of tracking performance. The suggested super twisting sliding mode control (ST-SMC) scheme incorporates the advantages of a sliding mode controller and eliminates the problem of chattering. Thus, improved dc-link voltage stability and high robustness for accurate reference voltage tracking are obtained. The output voltage in the DAB converter depends upon the power transferred through the transformer. The transferred power is a function of the phase shift of the voltage waveform of two H-bridges. The phase shift ratio is computed through the ST-SMC controller presented here utilizing the output voltage dynamic equation and power transfer equations for DAB converter. The proposed scheme which provides a robust control and an improved reference voltage tracking to the DAB converter performance. The proposed ST-SMC scheme is validated by simulation for 1 kW DAB converter in MATLAB-Simulink environment.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129424759","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}
