As an important controllable resource, friendly power electronics loads (FPELs), e.g. air conditioners, water heater, can be introduced to improve reliability and stability of microgrid. A friendly load control scheme considering importance degree and intention of loads was proposed to introduce FPELs into power generation and demand balance of microgrid. In microgrid, frequency can indicate power generation and demand balance. When the frequency below and near its minimum value, it means that the power generation is near to rated capacity. Friendly load control scheme can trigger the FPELs to reduce their power consumption according trigger signal preset for every FPEL. The load power was controlled along with frequency deviation, importance degree and intention of loads. This control scheme can automatically introduce the loads in power generation and demand balance control of microgrid. It can save reserve capacity of energy storage and reduce investment of microgrid. Simulation results show the effectiveness of the proposed control scheme.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124917223","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}

DPV lacks visibility and control from system operators, and this issue becomes critical especially during and after grid contingencies. Technical standards applicable to DPV inverters define expected performance and behavior, however they do not always provide clear guidelines under several grid disturbance conditions. On the one hand, inverters are allowed to respond flexibly. However, knowledge of inverters behavior under grid voltage disturbances is necessary to design and tune the parameters of composite load models, used by power system operators in planning the required power reserve. This article investigates through experiments the sensitivity and behavior of 25 off-the-shelf residential DPV inverters under grid voltage swells. Inverters are found to behave in either of these ways: 1) Ride-through, 2) curtail power, and 3) disconnect. Power curtailment or disconnection under such disturbances can have a detrimental impact on power system security. Accordingly, power system operators should schedule enough power reserves or take other appropriate measures.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"276 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123026827","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 is a key feature that makes GaN devices a potential candidate for power converters driving high speed electric machines. The switching transients occur in tens of nanoseconds leading to very high dv/dt and di/dt. This leads to several challenges for both power converter as well as motor load. Switching device voltage overshoot and insulation stress for motors are key concerns among them. A practical operation of power converter needs to consider minimizing the losses while addressing these challenges. Analytical models for switching transient help in investigating the mitigation of these challenges from the gate drive side. This paper presents a systematic modeling approach that divides the turn-on and turn-off transient intervals of a GaN-based two-level pole into sub-intervals responsible for di/dt and dv/dt. The switching loss contribution of each sub-interval and their role in transient overshoot is highlighted. Using switching device voltage overshoot and motor dv/dt as two important constraints, an optimal gate drive is then proposed, which minimizes the switching loss. Spice simulation results are presented for the proposed optimal gate drive of 650 V, 60 A GaN device operating at 400 V DC bus voltage and 40 A device current.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116517575","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}

By using the 2-D fast Fourier transformation, the time and spatial harmonics of the radial and tangential electromagnetic force were decomposed. In the meanwhile, vibration characteristics under different phase angles of armature current with field weakening control of the SPMSM were analyzed by the mode superposition method based on a multi-physics model. The results show that the phase angle of the armature current has a significant influence on the electromagnetic excitation force harmonics. It's effective to use the field weakening control to reduce the electromagnetic vibration of SPMSMs. This research will contribute to electromagnetic design and field weakening control strategies of SPMSMs.","PeriodicalId":145366,"journal":{"name":"2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127731348","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}
