Energy storage can mitigate this issue as the generated power can be stored and used at the needed time. Integrating energy storage directly in the PV panel provides advantages in terms of simplified system design, reduced overall cost and increased system flexibility. Incorporating supercapacitors directly in the PV panel on module or cell level raises some challenges regarding the electrical integration, such as charge controlling for the capacitors, capacitor matching, as well as internal power electronics layout. Physical integration of graphene supercapacitors with solar cells, at module- or cell-level presents challenges related to physical dimensioning, thermal management and life expectation of the entire system. The main goal of this article is to review the supercapacitor technologies and perform a comparison between the available supercapacitors in the market and selecting the most suitable type for developing supercapacitor-based integrated PV – energy storage systems, to achieve optimal electrical and physical integration.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"556 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116398817","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}

Modulation techniques, number of submodules, output voltage levels, arm inductance, and series damping resistance play an essential role in obtaining different waveforms with good quality. Phase-Shift Carrier (PSC) modulation technique proves to be a superior modulation technique for different periodic waveforms over Nearest Level Control (NLC), even when a large number of submodules is considered. With the traditional second-order filter design strategy, proper values of the arm inductance and series resistance can be selected, guaranteeing a good quality of the generated voltage waveforms to verify different dielectric properties of grid-assets. The design of such an AWG is demonstrated with the simulations in MATLAB-Simulink.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126917305","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 approach acts directly on the phase angle used for reference frame transformations in the control system and can be generally applied to all VSM-based control schemes relying on a virtual swing equation. A small-signal model of a selected VSM implementation with the proposed feedforward control is derived. This model is utilized to assess the impact of the power reference feedforward on the operational characteristics of the VSM. The improvement of the power reference tracking capability is demonstrated by analysing the transfer function from the power reference to the power injected to the grid, as extracted from the small-signal model. The frequency domain analysis also demonstrates how the oscillation modes of the VSM and the inertial response to grid frequency perturbations remain unaffected by the proposed feed-forward control. Finally, the findings from the frequency domain analysis are verified by time domain simulations.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127847453","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}

Therefore, the optimization of these machines is an computationally expensive optimization problem. The novel artificial intelligence methods and surrogate modeling techniques based on hp-adaptive FEM techniques can significantly reduce the computational cost. In case of a cogging torque or a torque ripple calculation, many simulations should be performed to make an accurate estimation of a single quantity. The number of calculations can be reduced by using surrogate modeling techniques. However, the surrogate model-based model’s extrema can differ from the original task’s optima. This paper presents a surrogate-model based cogging torque minimization of an axial flux permanent magnet synchronous machine. The objective function of this optimization is the cogging torque, the full solution space is explored to examine and show the robustness of the different kind of solutions.","PeriodicalId":349940,"journal":{"name":"2021 IEEE 19th International Power Electronics and Motion Control Conference (PEMC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126946772","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}
