Abstract Quantitative measurement of the high-speed gas-liquid-solid multiphase jets generated during the transient discharge of high-pressure vessels remains a significant challenge. Traditional Particle Image Velocimetry (PIV) techniques often fail in these scenarios due to the intense self-luminous interference, high transient velocities, and the absence of pre-seeded tracer particles. To address these issues, this paper proposes a robust non-intrusive measurement scheme integrating an adaptive image enhancement strategy with an improved cross-correlation algorithm. First, a preprocessing framework combining Contrast Limited Adaptive Histogram Equalization (CLAHE) and frequency-domain high-pass filtering is developed to suppress background noise and reconstruct fluid textures… More >

Abstract With the continuous expansion of installed capacity of renewable energy represented by wind power, modern power systems are increasingly characterized by high penetration of power electronics. This trend leads to reduced system inertia and compromised disturbance resilience, posing prominent challenges to frequency stability. Mainstream wind turbines operating in maximum power point tracking (MPPT) mode typically lack effective responses to system frequency fluctuations. Although conventional fixed-parameter virtual synchronous generator (VSG) technology can provide inertial support, it struggles to balance dynamic response speed and operational stability under variable operating conditions. To address these issues, this paper proposes… More >

Abstract The power transformer serves as a critical hub equipment in the electric power industry, performing the core functions of voltage transformation and power transmission in power grids. Among various potential hazards, through-fault short-circuit impacts are particularly destructive, capable of inducing severe deformation of the transformer windings and even triggering internal faults, thereby posing a major threat to grid stability. Consequently, accurate diagnosis of transformer damage after short-circuit impacts and scientific formulation of targeted overhaul strategies are of vital practical significance for ensuring safe and reliable power supply. In this paper, a comprehensive diagnostic analysis method… More >

Abstract Numerical calibration of wind power is a critical strategy for mitigating power generation deficits and optimizing the micro-siting of wind turbine units. As wind energy development shifts towards mountainous regions, accurate assessment in these environments becomes increasingly challenging due to complex turbulence structures. This paper conducts a theoretical and numerical investigation of atmospheric boundary layer flow in complex terrain. Utilizing the industry-standard Askervein Hill benchmark for validation, we first evaluate the influence of top boundary condition settings in rectangular fluid domains on the simulation accuracy of the equilibrium atmospheric boundary layer. Subsequently, the study proposes… More >

Abstract To address the challenges of low inertia support capability and poor frequency stability encountered in the process of power system electronification, this paper designs a coordinated inertia support control strategy for offshore wind power connected to the grid via Modular Multilevel Converter Based High Voltage Direct Current (MMC-HVDC), which enhances the system inertia level and accounts for secondary frequency drop. In terms of inertia support, building on the existing coupling relationship between grid frequency and DC voltage, the influence of wind turbine (WT) rotor speed is further integrated, leading to the proposal of a virtual… More >

Abstract Erectile dysfunction (ED) has evolved from a quality-of-life concern to a recognized marker of systemic vascular disease and an early harbinger of cardiovascular events. The Princeton IV Consensus underscores that men presenting with erectile dysfunction should be presumed at increased cardiovascular risk until proven otherwise, advocating integrated risk stratification and lifestyle optimization. Beyond established risk scores, advances in omics, vascular imaging, and digital health promise precision tools for early detection and prevention. This review aims to examine erectile dysfunction as an early marker of cardiovascular disease and to summarize current and emerging approaches to cardiovascular More >

Abstract Static Windows Portable Executable (PE) malware detection remains a significant challenge due to the growing use of packing, obfuscation, and code reuse techniques, which gradually reduce the effectiveness of signature-based and manually engineered feature approaches. Recent deep learning models that operate directly on binary code or static features have achieved encouraging results; however, most still rely on global file-level representations. Such approaches are susceptible to noise introduced by padding or obfuscation and may overlook localized malicious regions. Moreover, many multi-view methods process different feature sources independently, lacking mechanisms to enforce semantic consistency across views. This… More >

Abstract Offshore wind energy plays a critical role in achieving global decarbonization goals, while the dynamic response mechanisms of megawatt-scale turbines under complex environmental conditions remain insufficiently characterized. Current research often oversimplifies the effects of monopile flexibility and its interaction with soil dynamics, leading to gaps in dynamic predictions. To address this limitation, this study develops a comprehensive 15-degree-of-freedom dynamic model for a 22 MW monopile offshore wind turbine (OWT) that incorporates nonlinear pile flexibility and soil-structure interaction through p-y and Q-z curves. The integrated analytical framework, established using Euler-Lagrange equations, enables coupled analysis of… More > Graphic Abstract

Abstract To address the uncertainty and volatility of renewable energy while meeting the requirements of low-carbon economic operation, this paper proposes a two-stage robust optimal dispatch model for an integrated wind-solar-hydro-thermal-storage energy system with coupled power-to-gas (P2G) and carbon capture system (CCS). First, a mathematical model of the integrated wind-solar-hydro-thermal-storage energy system with P2G-CCS coupling is developed to promote internal carbon cycling and enhance the capability to accommodate renewable energy. Second, the scheduling problem is formulated as a two-stage robust optimization model. A cardinality-based uncertainty set is adopted to model deviations in renewable energy output, and… More >

Abstract The widespread integration of large-scale wind power has resulted in decreased equivalent inertia in power systems, thereby compromising their frequency regulation (FR) capabilities. Conventional synthetic inertia control faces challenges under stochastic wind conditions, including inadequate utilization of rotor kinetic energy in high wind condition regions and the risk of triggering rotor speed stability limits in low wind condition regions. To overcome these limitations, in this paper, a parameter adaptive synthetic virtual inertial control (SVIC) framework based on wind speed partition is proposed. The control mechanisms are designed differently across partitioned wind condition intervals: in high-wind-speed More >
