Capacitor-current-feedback active damping has been widely adopted in digitally controlled LCL-type grid-connected inverters (GCIs). However, their digital control delay causes the system stability to deteriorate within a negative range. Particularly, weak grid, such GCIs are prone be unstable against grid impedance variation. To address above problem, compensation strategy is proposed for an GCI, which second-order low-pass filter (LPF) inserted into capacitor-current-feedback path. This...
Aiming to solve the optimal control problem for pursuit-evasion game with a space non-cooperative target under condition of incomplete information, new method degenerating into strong tracking is proposed, where unknown maneuver processed as colored noise. First, relative motion modeled in rotating local vertical horizontal (LVLH) frame originated at virtual Chief based on Hill-Clohessy-Wiltshire dynamics, while measurement models three different sensor schemes (i.e., single LOS...
The stability of grid-connected inverters is very sensitive to varying grid impedance, especially in the weak condition. In this paper, based on Lyapunov method and with micro-grid impedance identification, an active damping adaptive control strategy proposed guarantee local asymptotic for LCL inverter system. First, using backstepping design taking state variable errors as new variables, appropriate function constructed, so that law can be obtained. Then, controller, into account,...
Large vision models have been found vulnerable to adversarial examples, emphasizing the need for enhancing their robustness. While training is an effective defense deep convolutional models, it often faces scalability issues with large due high computational costs. Recent approaches propose robust fine-tuning methods, such as tuning of low-rank adaptation (LoRA) in but they still struggle match accuracy full parameter fine-tuning. The integration various mechanisms offers a promising...

Preparing spin reserve power in advance is an efficient approach to address the intermittency of renewable energy. To promote renewables penetration levels and increase cost-efficiency bulk system, a novel flexible HVDC model that allows both energy transmitted across regions proposed. Based on this, risk based dynamic schedule (RBDRS) introduced for investigating systems. In addition, generation load centers locate separately extensive spatial range are usually managed by different system...
This paper investigates the short-term wind power fluctuation issues in an actual grid-connected industrial microgrid for aluminum production. As a type of energyintensive load, electrolytic load (EAL) presents great potentials smooth due to large capacity and characteristic.
