With its popularisation, electric vehicle (EV) has been part of the important load smart grid. The analysis on charging demands EVs is basis study influences power grid and infrastructures planning. Charging demand calculation based precise driving law users. This proposes a method stochastic simulation trip chain to solve existing problem. First, concept characteristic variables (trip start time, parking duration, distance purpose) are introduced. Second, probability distribution models...
As the country with world's largest coal power capacity, China is launching a national carbon market. How pricing may contribute to phasing out China's great concern. We collect full-sample data set of 4540 operating plant units and develop stochastic Monte-Carlo financial model assess sustainability operation. Although plants have long residual technical lifetime, their operations are close break-even state. Even low price 50 CNY/tCO2 growing at 4%/y permits being fully auctioned, average...
Abstract Artificial intelligence (AI) models have shown great accuracy in health screening. However, for real-world implementation, high may not guarantee cost-effectiveness. Improving AI’s sensitivity finds more high-risk patients but raise medical costs while increasing specificity reduces unnecessary referrals weaken detection capability. To evaluate the trade-off between AI model performance and long-running cost-effectiveness, we conducted a cost-effectiveness analysis nationwide...
Renewable energy is the development direction of power system China. To further boost China's industry, digital transformation underway. This study examined panorama Through analyzing effect on renewable utilization, three business applications were identified: short-term prediction output, equipment maintenance, and intelligent power-grid maintenance. The implementation process are analyzed by using data covering 2012-2019 from aspects: accuracy reduction fault restoration mean time for to...
A detailed investigation of the nexus between economic growth and energy use is imperative for formulating sustainable development policies. In this study, we examine panel cointegration causality relations among growth, use, capital stock, labor in 30 Chinese provinces 2000–2019. We conduct a comprehensive empirical analysis based on modeling neoclassical production function. The findings second-generation unit root co-integration tests reveal that these variables have long-term linkages....
Given the pillar role of renewable energy in low-carbon transition and balancing storage, many supporting policies have been promulgated worldwide to promote their development. To achieve ambitious goal no less than 1200 GW wind solar by 2030, China has also introduced encourage deployment storage for grid integration energy. The national policy is conducive enhancing system flexibility integration, but it will add costs energy, especially when counting regional differences. This paper...
The accelerated growth of the global economy has given rise to a multitude environmental concerns that demand immediate attention. At this juncture, total carbon emissions are exhibiting gradual increase. China, United States, India, Russia, and Japan represent top five countries in terms emissions, collectively accounting for approximately 60% total. Of these, China’s highest world, representing over 30% As urbanization accelerates, from urban agglomerations constitute substantial share...
As the global shift away from fossil fuels intensifies, distributed photovoltaics (PV) have emerged as most significant and swiftly expanding renewable energy source accessible to end-users due their convenience in flexible deployment. Coupled with steep decline storage costs, co-deployment of PV systems (PV-ESS) has become a preferred option for electricity users, especially large ones. The PV-ESS investment decision-making model is encountering new obstacles stemming gradual withdrawal...
As Artificial intelligence (AI) has been increasingly integrated into the medical field, role of humans may become vague. While numerous studies highlight AI's potential, how and AI collaborate to maximize combined clinical benefits remains unexplored. In this work, we analyze 270 screening scenarios from a health-economic perspective in national diabetic retinopathy program, involving eight human-AI collaborative strategies traditional manual screening. We find that annual copilot 20-79 age...
This letter proposes a fast approach to calculate the power oscillation peak value on AC tie-line after HVDC commutation failure. The proposed does not require modeling system components in detail for dynamic simulation and is especially suitable practical bulk systems. It useful help operators rapidly assess stability margin failures. has been implemented China.
China's target to achieve carbon neutrality by 2060 entails the phase-out of high-emissions coal power. However, a just transition policy must be implemented, given that power and its upstream mining industry provide many employment opportunities. Leveraging bottom-up tabular analysis, we assessed impact on coal-fired plant closures in 330 prefecture-level cities. We identify vulnerable areas for propose customized incentive through vulnerability assessment framework. Results show 2020,...
The utilization of power electronic-based converters is gaining momentum across a wide spectrum industries. However, modern electronic operate at higher frequencies compared to conventional converters, which can lead rates change in voltage and current during phase switching, thus potentially produce more severe conducted radiated electromagnetic interference (EMI). Their compatibility (EMC) has become critical research topic, EMI high-frequency complex than that converters. This review...
Recently, a new oscillation phenomenon—intermittent subsynchronous (ISSO)—has been observed in large interconnected power grid. Rather than leading to oscillatory instability, ISSO causes cumulative fatigue damage and reduces the shaft life of generator. The existing phase-compensation-based damping technologies are found be limited mitigating these types oscillations. To mitigate ISSO, modulation reactive current (SMRC) approach is established implemented voltage-source converters (VSCs) at...
