An improper rotor shape design may cause large torque ripple and decrease the motor torque density. To solve this problem, a convenient rotor shape design method of NFB-SynRMs is proposed and the rotor profile function is derived. The effectiveness of the proposed method is verified by electromagnetic finite element analysis.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126405111","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 is of great significance to study the control strategy for the overvoltage problem of the highpenetration photovoltaic distribution network to realize the consumption of photovoltaic equipment.The paper analyzes the mechanism of voltage over-limit firstly, under the background that various existing schemes have poor controllability of voltage regulation and cannot meet power quality requirements, an active-reactive power coordinated control strategy is proposed. When the distribution network is facing the risk of voltage exceeding the limit, combined with Q-U droop curve, power constraint equation and inverter capacity constraint, the reactive power of the line is regulated by the residual capacity of the inverter; in order to ensure that the power factor of the grid meets the system requirements, when the maximum reactive power adjustment capability of the inverter is reached, the active power control so that voltage requirements are finally met. The effectiveness of this control strategy in solving the voltage crossing problem in a five-node distributed PV distribution network is verified by MATLAB simulation.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121070425","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}

Virtual synchronous generator (VSG) control has been widely used in renewable energy grid connection because of its excellent reactive power support ability. However, the fault ride-through ability of traditional VSG is weak, and VSG is prone to overcurrent when the power grid short circuit fault occurs. Therefore, this paper proposes a fault ride-through method for VSG based on reactive feedback coefficient optimization. The active power compensation is added to improve the power angle stability of the VSG. The reactive power feedback coefficient is designed based on the maximum output current of VSG to maximize voltage support capacity. Considering the case of a small voltage sag fault, the target voltage adjustment strategy is added to control the output voltage of VSG within the standard operating range. Finally, simulation results demonstrate the effectiveness of the proposed strategy.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"214 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133999520","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}

However, existing linear power flow equations are proposed based on empirical assumptions. The optimality of these power flow equations cannot be proven. The evolutionary pathway of the linear power flow equation is not clear. In this paper, we review the widely-used linear power flow equation from the perspective of their zero-error assumption of linearization approximation. Then, the improvement of the linear power flow equation is revealed as constantly breaking the zero-error assumption. Finally, we propose an enhanced linear power flow equation based on the arithmetic-geometric mean inequality for optimal power flow (OPF) calculation.
