Power system requires developing more flexible sources to handle the variability and stochastic of ever-increasing renewable energy. Retrofitting conventional coal-fired power plants (CPPs) is a viable promising pathway for providing large-scale flexibility at this stage. Typical retrofit technologies mainly include reducing minimum load, improving ramping capability, speeding up startups/shutdowns. They involve multiple subsystems CPPs coupled technical issues, they have different...
Evaluating the carbon storage of forests and identifying factors that influence it are essential in working towards “dual carbon” goal. This assessment will facilitate research on neutrality promote regional ecological protection development. study utilized “One Map” data forest resources (2020) first year (2017) establishment national park Wuyi Mountain National Park (WMNP). The continuous biomass expansion factor method, conjunction with vegetation content coefficient, was employed to...
Modular multilevel converter (MMC) is a modern and preferred topology among the voltage source converters (VSCs) in high direct current (HVdc) transmission. However, traditional half-bridge sub-module (SM) cannot block dc fault current. Hence, novel SM with ride-through capability introduced. This article proposes an improved diode-clamp (IDCSM) structure. Based on DCSM topology, two capacitors' connection IDCSM modified to operate independently generate output levels of <inline-formula...
To reduce the efforts of human in browsing long surveillance videos, synopsis videos are proposed. Traditional video generation methods condense most activities by simultaneously showing several actions, even when they originally occurred at different times. This inevitably causes ignorance temporal relationship among objects. For example, two persons walk shoulder to and detected tracked separately, but never ‘met’. In this study, a trajectory mapping model is defined, whose energy function...
The subsynchronous interaction between the wind farm's grid-side converter and series-compensated transmission line can trigger oscillations (SSO). power system oscillation frequency depends on actual operational conditions. This paper proposes a repetitive-PI control strategy to mitigate under various offers fast dynamic performance high steady-state accuracy, which eliminate errors improve system's robustness. Firstly, composite controller is derived based domain expansion of repetition...
In this paper, a robust path-following control strategy is proposed to deal with the problem of underactuated autonomous underwater vehicle (AUV) multiple uncertainties and input saturation, effectiveness verified by semi-physical simulation experiments. Firstly, laws are constructed based on traditional backstepping method; treated as lumped uncertainties, which can be estimated eliminated employed extended state observers (ESOs). addition, influence saturation compensated designed...
Energy combustion is the primary source of CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> emissions in China. Coal-fired power generation, particular, a significant consumer energy. To achieve carbon peaking and neutrality goals, it crucial for coal-fired plants to select suitable methods calculating accounting them. Starting from emission sources using principle least squares, qualitative quantitative analyses, different are...
Vapor–solid growth (VSG) is a cost-effective technique to synthesize Bi2Se3 materials with promising thermoelectric (TE) performance. In this work, smooth thin films enhanced TE performance have been realized through regulating the carrier gas flow rate during VSG process. The optimized morphology improves electrical conductivity and decouples its interplay withthe Seebeck coefficient in Bi2Se3. As result, our synthesized at 150 sccm exhibited around −100 μV K–1 power factor (PF) of 1.59 ×...
