Recently, the dc grid concept has been considered a cost-effective and efficient option in modern power distribution systems, where one of its most valuable applications is to support the frequency and voltage of low-inertia and weak grids. However, the literature does not fully address a comprehensive stability analysis and performance assessment of a low-inertia system supported by a dc grid. Therefore, this paper presents a thorough yet straightforward dc-side impedance-based stability analysis of a low-inertia ac grid connected to a dc grid via a bidirectional voltage-source converter (VSC) equipped with a virtual inertia controller to improve the ac grid frequency behavior. In the proposed virtual inertia control, low-pass and high-pass filter implementations are investigated, and their performance is compared. The dc-side equivalent impedance models are developed for the 1) interlinking VSC combined with its ac grid, considering virtual inertia control and typical ac grid components: synchronous generators (with their turbine, governer, and exciter models), induction motor loads, and static loads, and 2) dc grid considering its practical components: distributed generators, constant-power loads, and resistive loads. Therefore, unlike previous methods, the proposed impedance modeling and stability analysis approach considers the impacts of the ac grid frequency/voltage dynamics and dc grid dynamics on the VSC dc-bus stability. Impedance interactions are characterized and used to assess the overall system dynamics and stability and the impacts of the system and control parameters. The analytical results are validated by detailed offline and real-time simulation studies.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"485-503"},"PeriodicalIF":5.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10884886","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also explores how interactions between long cables inductive impedance and EMI filter capacitors can influence the system performance, distinguishing it from previous works. The study examines a dc microgrid consisting of two connected cascaded buck converters. Two scenarios are analyzed: one considers no filters between the two converters, while the other includes a low-pass filter (LPF), an EMI filter, and a cable feeder between them.

Compared with the existing research that simplifies SiC MOSFET model in the RTS implementation process, the proposed modeling method not only considers the hard-switching process caused by insufficient deadtime, and the special switching mode that the channel turn-off precedes the antiparallel diode turn-on in opposite device, but also fits the nonlinear characteristics of the SiC MOSFET through look-up tables (LUTs). In addtion, the parallel solution structure of the FPGA-based RTS model is completed through hardware optimization design scheme.

However, 3L modulation makes it difficult to address the requirement of a wide output voltage range. Therefore, this paper presents a hybrid modulation method for the DNPC-LLC converter, incorporating the traditional 3L modulation and a proposed two-level (2L) modulation, which allows lower output voltages, reduces the switching frequency and the number of switching operations of the primary-side switches. Furthermore, the operating principles and voltage gains of both modulation methods are analyzed. Finally, a 3.7 kW SiC-based DNPC-LLC converter with synchronous rectification at an 800 V input is implemented. The output voltage ranges from 20 V to 450 V, and smooth transitions between different modulation modes are verified. The proposed converter achieves a maximum efficiency of 97.3% at an output of 360 V and 10.3 A. Furthermore, compared to the 3L method, the 2L method improves efficiency by at least 0.5% when the output voltage is below 200 V.

The objective of this robust control approach is to mitigate cross-coupling challenges inherent in MIMO systems and effectively manage the parametric uncertainties associated with the converter as well as input and output disturbances. To achieve this objective, the paper begins with deriving the general nonlinear dynamic equations of an n-level step-up multi-port DC/DC converter (<inline-formula><tex-math>${MPDC}_{nL}^{SU}$</tex-math></inline-formula>). Subsequently, for a case study involving a 3-level step-up multi-port DC/DC converter (<inline-formula><tex-math>${MPDC}_{3L}^{SU}$</tex-math></inline-formula>) the equations are linearized to obtain the state-space model. Following the derivation of the converter model, a controller comprising two control loops is designed.

A detailed small-signal state-space model of the overall CSC-based system is developed to investigate the system's stability under different practical parameters, such as wind power reserve, control parameter, and short-circuit ratio variation. The equivalent dc-side impedances of the grid and machine-side CSCs are also developed and used to characterize the dc-link stability using the Nyquist stability criterion. A systematic design approach for the control parameters is presented. Nonlinear-model time-domain simulations are presented to verify the analytical results and assess the performance under various operating conditions, such as grid disturbances, faults, and parameter uncertainty.
