“…An effective method for significantly improving tracking performance is Model Predictive Control (MPC), which is classified as one of the nonlinear control strategies currently applied in DC/DC converters [66]. This approach has garnered considerable attention in power converters and motor drive systems [67,68]. In MPC, achieving high-precision tracking relies on having an accurate and effective system model, which is a challenge persistently hinderd by system disturbances and uncertainties in model parameter realization [61,66].…”

DC microgrids (DC MGs) offer advantages such as efficiency, control, cost, reliability, and size compared to AC MGs. However, they often operate with numerous constant power loads (CPLs), exhibiting a negative incremental impedance characteristic that can lead to instability. This instability weakens stability boundaries and reduces system damping, especially when dealing with pulsed power loads (PPLs) on electric aircraft, ships, and cars. Linear controllers may not ensure stability across various operations, causing voltage dips and potential system instability. To secure DC/DC converter functionality and comply with impedance specifications, it is crucial to consider minor loop gain in control strategies and stabilization techniques. Employing diverse methods to decrease minor loop gain in DC/DC converters is essential. A comprehensive evaluation, including strengths, weaknesses, opportunities, and threats (SWOT) analysis, is conducted to assess control strategies, stabilization techniques, and stability standards for different DC/DC converters, identifying SWOT.

“…The small-signal stability analysis of conventional power systems has been well established. More and more researches have focused on the stability analysis of low voltage DC microgrids [22][23][24][25][26] and HVDC transmission & distribution networks [21,[27][28][29][30][31][32][33]. The small-signal model of the converter-based microgrid is established to investigate how circuit and control parameters give rise to the oscillatory modes and the damping performance of these modes [22].…”

This paper presents a detailed and accurate small-signal analysis model for a four-terminal low-voltage direct current (LVDC) distribution network with distributed secondary control strategy. To tackle the contradiction between power sharing accuracy and average voltage recovery ability of voltage source converters (VSCs), a distributed secondary control strategy is adopted, which is based on average consensus algorithm and local voting protocol. Furthermore, to analyze the stability of LVDC distribution network based on the proposed distributed secondary control strategy, a detailed and accurate small-signal analysis model is formulated which is derived from various non-linear state-space sub-models. The time-domain simulation and electromagnetic simulation are carried out to verify the validity and accuracy of the proposed model. Based on this model, the influence rules of main eigenvalues are summarized with the variation of PI control and DC line parameters. Time-domain simulations conducted in PSCAD are used to validate the operational limits of the secondary controllers and DC line obtained from the small-signal stability analysis.
