Biomass co-firing technology is a potential solution for low-carbon transition of coal-fired power plants. Existing techno-economic analyses this fail to consider indirect benefits, such as avoided losses from retrofitting, and the heterogeneity across regions. To address these limitations, we developed five types indicators analyze six possible future scenarios application in 29 provinces China, based on regional heterogeneous data. The results show, first, generally, higher local coal...
Background: Ticks are important vectors for many pathogens affecting humans and animals. This study was aimed at investigating the species composition, genetic diversity, potential transmission risks of tick-borne in Guangxi Zhuang Autonomous Region, China. Methods: A total 980 ticks were collected from 14 prefecture-level cities between March July 2021. identified morphologically genetically, population diversity Rhipicephalus microplus analyzed according to 16S rDNA, COXI , ITS-2 gene...
With the rapid development of inverter-based generators (IGs), power grid is faced with critical frequency stability challenges because existing IGs have no inertia. To equip inertial response, researchers proposed several virtual inertia control methods, which can be classified into two categories: synchronous generator (VSG) and droop based on rate change (ROCOF-droop control). In this paper, comparison between both methods conducted from three perspectives: mathematical model, output...
With the rapid development of Artificial Intelligence (AI) technology, application AI in field education has gradually become one key factors improving teaching quality and student abilities. Based on conservation resources theory, this study explores how usage impacts students’ creativity, exploring mediating role learning engagement moderating literacy. The research finds that significantly enhances with playing a process, thereby promoting creativity improvement. In addition, literacy...
As a new dynamic maintenance strategy, the condition-based opportunistic strategy for multi-component system is presented in this work. In degeneration of each component described by Weibull proportional hazards model or intensity model, and condition indicator defined to characterize operating state component. Then, when how maintain can be confirmed comparing value with that threshold function. Condition-based will implemented on if its exceeds Meanwhile, also The two functions determined...
At present, the stability of virtual synchronous generator (VSG) is mainly studied in micro-grid or single grid-connected VSG, and multiple VSGs still lacked research. This paper builds small signal models VSGs, influence VSG control parameters (active power droop coefficient, inertia, etc.) on characteristic roots system are discussed. Besides, difference between compared. Finally, correctness modeling results analysis verified by simulation. The this show that when systems same, basically...
The nonlinear friction, unmodeled disturbance and coupling torque caused by the movement of satellite are main factors limiting angular speed accuracy in gimbal system single control moment gyro (SGCMG). Consequently, a high-precision servo based on cascade extended state observer (NCESO) is established this paper order to reduce influence those disturbances improve output velocity system. simulation results confirmed feasibility effectiveness proposed method.
Firstly, this paper analyzed in theory two kinds of frequency regulation control strategies, swing equation strategy and additional characteristics strategy, which were adopted by the demonstration project. The differences between strategies modulation start-up time, oscillation risk, mode supporting power, inertia response dead zone so on compared studied. Then, relying recorded field data, showed actual effect strategies. Lastly, we optimized VSG proposed new ones to make full ues...
At present, the research of Static Var Generator (SVG) mainly focuses on main circuit topology, optimization control strategy, method selection, and lack low frequency oscillation wind farm caused by SVG minimum reactive output dead zone in practical engineering applications. For this reason, paper first studies mechanism electric field induced farm, discusses conditions type oscillation. On basis, automatic voltage system (AVC) model is established with variation near zero point as goal, an...
Virtual Synchronous Generators (VSG), as an effective mean to improve the frequency and voltage regulation ability of photovoltaic power generation, had aroused wide concern. The analysis on whether VSG would cause stability problem became important issue ensure safety system. is enormous challenge because this not only retains characteristic electronic devices but also emulates essential behavior synchronous generators. Existing studies concentrated device risk oscillation when applied in...
An experimental research of the effect H2 substitution and CO2 dilution on CH4 combustion has been carried out a spark ignition engine. The results show that addition could improve BMEP, thermal efficiency, CO THC emissions. NOX emissions increased for higher low heating value (LHV) than CH4. effective reduce emission H2-CH4 combustion. Although engine performance, efficiency exhaust get unacceptable under high fuel ratio (F.D.R.) conditions, it be solved by decreasing F.D.R. and/or...
As the penetration rate of new energy increases, inertia and damping power system gradually decrease, stability problems become increasingly prominent. Virtual Synchronous Generator (VSG) technology has gained widespread attention application as an effective means to improve ability generation systems actively support grid, therefore, research impact VSG on transient also a hot spot. Firstly, analysis method angle is introduced, then influence conventional Doubly-fed Induction (DFIG)...
