As the role of these renewable DERs grows in power systems, the grid frequency characteristic becomes softer due to the reduced system inertia. Standards and international grid codes have been issued for grid interconnection of DER inverters with frequency regulation capability, which expects DER system to regulate the grid frequency by adjusting the active power injected into the grid. Therefore, the renewable DERs should not operate at maximum power point so it can increase or reduce power output according to the set slope to participate in frequency regulation. Traditional frequency droop control methods adjust the target power at the same rate no matter the frequency deviation is large or small, which does not fully utilize the rapid response of power electronic converters in DERs. This paper proposed a new frequency regulation method based on a parabolic droop curve, which makes better use of the rapidity and flexibility of DER inverters by restoring the frequency slower when the frequency deviation is small and restoring the frequency faster when the frequency deviation is large.","PeriodicalId":374979,"journal":{"name":"2021 IEEE 12th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127487837","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 three-terminal DC system is chosen as a case study with different terminal modeling. Terminal 1 is modeled with conventional vector current control and circulating current control. Terminal 2 is modeled with a Fault-Tolerant Controller and dq based circulating current control, and terminal 3 is modeled with a conventional vector current control with no circulating current control. In addition to the control structure, Nearest Level Modulation (NLM) is adopted for each terminal. The MTDC system is investigated based on the total reliability and availability of the terminals. Besides, analytical loss and cost calculations are performed for the three-terminal DC system. Different redundancy techniques for MMC arms are presented, but a 10% active redundancy scheme is adopted in the three-terminal DC system.","PeriodicalId":374979,"journal":{"name":"2021 IEEE 12th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115986184","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}

Moreover, the high critical electric field of GaN makes it excellent choice for power semiconductor devices. It has the capability of switching hundreds of volts in nanoseconds, giving it multiple megahertz capability. However, to enable this feature, advanced packaging structure with optimized stray parameters is required. The traditional wire-bonded package of power module has large parasitic inductance, which will cause voltage overshoot, oscillation, parasitic turn-on, and EMI issues. A gate driver integrated wire bondless solution for a GaN half-bridge, phase-leg module is presented in this manuscript. A global optimization is done to achieve 0.68 nH power loop inductance, 1.25 nH gate loop inductance and 0.257°C/W thermal resistance. The hybrid combination of printed circuit board (PCB) and direct bonded copper (DBC) substrate enabled vertical commutation loop, which has helped to limit the stray inductance substantially. The fabricated module shows excellent switching performance with turn-off speed as high as 192 V/ns while not exceeding the voltage overshoot more than 15% of applied DC link voltage.","PeriodicalId":374979,"journal":{"name":"2021 IEEE 12th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"622 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116078934","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 observing the dynamic characteristic of Q, it is possible to correlate the attack with the nominal response of the hierarchical controller. The article shows that the occurrence of the attack can be identified through a supervisory control that runs a model in parallel. The article argues that after an early identification of the attack, a local controller can take action to mitigate its effects on the system’s response.","PeriodicalId":374979,"journal":{"name":"2021 IEEE 12th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129110414","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}

Conventionally, the first harmonic approximation (FHA) analysis method is used to perform the zero-voltage switching (ZVS) analysis for LLC resonant converter. However, the FHA method assumes that the LLC resonant converter is always operating at resonant frequency point so that the primary switch turn-off current is a constant value during the whole operation range. When the LLC resonant converter operating point is away from the resonant frequency, considerable errors would exist, which will lead to unoptimized deadtime design or ZVS failure. Therefore, in this article, a ZVS evaluation tool is developed based on the time domain analysis, the analysis results have much higher accuracy when compared with the traditional FHA method, which can be used to guide the analysis and design of the converter.

The control scheme estimates the inertia of the grid during disturbances by AI techniques and provides a feedback for the controller to regulate the frequency of the grid. The proposed integrated data-driven and model-based predictive control (IDMPC) is implemented on power electronics interfaces of the distributed energy resources (DERs) at the grid-edge and enables the control of islanded grid-cluster frequency feature such as rate of change of frequency (ROCOF) and nadir frequency.

The power flow control scheme of ST is dependent on the ST-fed network configuration, (e.g., radial or meshed network), which is also impacted by the grid condition, i.e., grid faults. An universal power flow control scheme to allow the ST operating in both radial network and meshed network can avoid the transition caused by switching the control schemes.

In this paper, an adaptive model prediction controller (AMPC) based on Deep Reinforcement Learning (DRL) is developed to tackle the de-stabilization problem. In the proposed AMPC controller, the controlling signal coefficient in each variable operation point is regarded as the adjustable controller parameter and adaptively designed by the learning ability of the Deep Q- Network (DQN) strategy, leading to a robust controlling approach.
