The short circuit current characteristics of LCC-HVDC transmission system are directly related to the action characteristics of AC protection at the inverter side. However, the single-end equivalent model of the existing LCC-HVDC transmission system regards the sending end as a pure traditional AC power supply, and the equivalent error is large when the sending end contains a high proportion of new energy. Based on the dynamic phasor equivalent calculation framework, this paper establishes a single-end equivalent model of the LCC-HVDC transmission system based on the AC information of the inverter side only, and analyzes the impact of different new energy proportion scenarios on the single-end equivalent error and the causes of the error. In this paper, simulation verification is carried out under the scenario of multiple new energy ratios at the sending end. The results show that the simulation error of the single-end equivalent model increases with the increase of the proportion of new energy, which reduces the credibility of the single-end equivalent calculation. © The Institution of engineering & Technology 2023.

In recent years, the performance of infrared and visible image fusion has been dramatically improved by using deep learning techniques. However, the fusion results are still not satisfactory as the fused images frequently suffer from blurred details, unenhanced vital regions, and artifacts. To resolve these problems, we have developed a novel feature attention-guided perceptual generative adversarial network (FAPGAN) for fusing infrared and visible images. In FAPGAN, a feature attention module is proposed to incorporate with the generator aiming to produce a fused image that maintains the detailed information while highlighting the vital regions in the source images. Our feature attention module consists of spatial attention and pixel attention parts. The spatial attention aims to enhance the vital regions while the pixel attention aims to make the network focus on high frequency information to retain the detailed information. Furthermore, we introduce a perceptual loss combined with adversarial loss and content loss to optimize the generator. The perceptual loss is to make the fused image more similar to the source infrared image at the semantic level, which can not only make the fused image maintain the vital target and detailed information from the infrared image, but also remove the halo artifacts by reducing the discrepancy. Experimental results on public datasets demonstrate that our FAPGAN is superior to those of state-of-the-art approaches in both subjective visual effect and objective assessment. © 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

DC grids utilizing MMC-HVDC technology have been extensively researched and implemented in various locations, demonstrating substantial benefits in terms of system flexibility and renewable energy integration. Due to the rapid escalation of fault currents, DC line protections must quickly identify and isolate faults, typically within milliseconds, leading to the adoption of non-unit methods as the primary protection. This paper introduces a non-unit protection scheme that employs transient voltage at both the line-side and converter-side of the supplemental inductor. Based on a reduced model focusing on the boundary of a DC line, the transient process of the fault is examined using traveling wave theory, and the voltage characteristics at both ends of the supplemental inductor are scrutinized. The theoretical analysis also brings out a practical method for threshold-value calculation. Then, a protection criterion, based on wavelet analysis of the transient voltage, is established. This proposed method is capable of fulfilling the requirements for speed, selectivity and fault resistance and has been verified through PSCAD/EMTDC simulations.

As the grid strength gradually weakens, there is an urgent need to enhance the weak grid adaptability and precise control capability of photovoltaic-energy storage (PV-ES) systems. This paper analyzes the basic principles of the PV-ES virtual synchronous generator (PV-ES VSG) control scheme under the common DC bus. A flexible control scheme for grid-connected PV-ES systems is proposed based on DC-link voltage synchronization control (DVSC). Compared to existing PV-ES VSG control schemes, the proposed scheme can significantly improve the control flexibility of the energy storage and increase the diversity of its control algorithms, while maintaining similar power support capabilities and grid-connected performance. This improvement not only optimizes the performance of the energy storage unit in the power grid, but also reduces its burden and pressure on DC bus voltage control. Simulation results based on MATLAB/Simulink and the experiment results based on the Hardware-In-Loop (HIL) platform validate the effectiveness and rationality of the proposed scheme. The comparison with the PV-ES VSG also shows the advantages of the proposed scheme. © 2024 IEEE.

Resilience-Oriented Transmission Expansion Planning under Hurricane Impact Considering Vulnerable Line Identification and Hardening

Resilient enhancement measures are crucial for increasing systems' capacities to deal with extreme natural disasters. However, in the pre-disaster prevention stage of hurricanes, research that simultaneously considers load importance, vulnerable lines, and multiple resilience enhancement measures is lacking. To address this issue, a novel resilience-oriented transmission expansion planning (ROTEP) model is proposed that incorporates two resilience assessment indices: the combined loss of loads (CLL) and the vulnerable line survival proportion (VLSP). In addition, the novel function of the proposed model meets the requirements of normal and hurricane damage scenarios based on the collaborative implementation of three resilience enhancement measures (expansion planning, hardening, and unit commitment). The proposed ROTEP model is structured in two stages. The first-stage model aims to meet the load growth demand while minimizing the total planning cost of transmission lines, the operating cost of generators, and the penalty cost of wind power and load shedding across several normal scenarios. Based on the scheme obtained from the first-stage model, damage scenarios are constructed, and a fault chain set is formulated using a hurricane simulation model. Then, a cascading fault graph is constructed to identify vulnerable lines. The second-stage model further enhances the CLL and VLSP (if necessary) under several damage scenarios by hardening the highest-contributing or most vulnerable line. Finally, the efficacy of the proposed ROTEP model for enhancing resilience is validated with a modified IEEE RTS-24 system and a two-area IEEE RTS-1996 system.
