The conventional grid-connected photovoltaic (PV) inverter is controlled by a dual-loop control strategy in synchronous reference frame, and the controllers are designed for steady-state operating point based on small signal model neglecting high-order coupling terms. However, an LCL filter, terms complicated due to dq transformation which will affect dynamic performance. In this paper, innovative simplified feedback linearization (SFL) proposed PV with offers satisfactory performance,...
[1] We provide a general framework for identifying the constituents responsible asymmetry in any tidal time series, by extending and generalizing skewness-based approach of Nidzieko (2010) to include number constituents. show that this statistic has two features which greatly simplify attribution particular constituents: (1) only combinations or three can contribute skewness, regardless how many are significant series (2) those combinations, few meeting frequency conditions 2ω1 = ω2 ω1 + ω3...
Abstract Projections of future sea-level changes are usually based on global climate models (GCMs). However, the in shallow coastal regions, like marginal seas near China, cannot be fully resolved GCMs. To improve regional simulations, a high-resolution (~8 km) ocean model is set up for China both historical (1994-2015) and (2079-2100) periods under representative concentration pathways (RCPs) 4.5 8.5. The simulations evaluated at different spatiotemporal scales, then integrated period,...
This paper mainly presents the research on hybrid energy storage system in a Micro-grid with DC Bus and an AC bus. The is based battery Ultra-capacitor. When sudden load was switched into Micro-grid, voltage of should be maintained to avoid stability problems. To fulfill requirement, parallel structure two bi-directional DC/DC converters has been chosen for also control method proposed. Simulation results have proved that designed proposed are applicable effective Micro-grid.
Abstract Wave–current interactions are crucial to suspended-sediment dynamics, but the roles of associated physical mechanisms, depth-dependent wave radiation stress, Stokes drift velocity, vertical transfer wave-generated pressure mean momentum equation (form drag), dissipation as a source term in turbulence kinetic energy equation, and current advection refraction energy, have not yet been fully understood. Therefore, this study, computationally fast model developed by Mellor et al.,...
Abstract. An evaluation of social vulnerability to storm surges is important for any coastal city provide marine disaster preparedness and mitigation procedures formulate post-disaster emergency plans communities. This study establishes an integrated system by blending a variety single-evaluation methods, which are subsequently combined weighting in order calculate common index. Shenzhen has current reputation having considerable economic development potential representative China. It chosen...
Previous studies have investigated the characteristics and influencing factors of plume bulge in Pearl River Estuary (PRE) using observations numerical simulations. However, understanding how river discharge affects is not consistent, response mechanism to changes has been revealed detail. In this study, a three-dimensional hydrodynamic Finite-Volume Coastal Ocean Model (FVCOM) constructed, five experiments were set characterize horizontal vertical distribution outside PRE under different...
Moored current measurements were made at one mooring site in the northern Gulf of Tonkin for about 1 year during 1988–1989. Analyses performed to examine characteristics and variability tidal subtidal flows. Rotary spectra showed two peaks diurnal semidiurnal periods, with higher energy. Complex demodulations currents indicated that magnitudes varied significantly seasons: more energetic stratified summer than vertically well‐mixed winter. The observed highly correlated surface wind winter...
This paper presents a low voltage ride through (LVRT) control strategy for high-power grid-connected photovoltaic (PV) inverter, which can assure the PV inverter operates under grid faults with sinusoidal output currents. The of is made up inner current loops and outer loop in cascade structure normal working conditions. regulates on dc-link capacitance to maximum power point arrays, are composed four closed positive sequence negative synchronous reference frame. If fault signal has been...
Abstract River floods and human activities would impact land‐to‐sea sediment transport, which is essential for understanding the evolution of global cycle in Anthropocene era. This study focused on investigating how river a dike constructed 2005 along channel influence transport from Ou Estuary to East China Sea. A validated three‐dimensional model based Finite Volume Community Ocean Model was utilized this study. The presence obstructs alongshore currents fish migrations, leading negative...
Parallel operation techniques can be applied to inverters, especially in high power applications. This paper proposed a parallel structure of three phase voltage source which individual modules connected both DC and AC sides directly without additional passive components. The Carrier Phase-Shifted SPWM (CPS-SPWM) technique is used suppress the output current total harmonic distortion (THD). However, switching action each module would asynchronous due CPS-SPWM strategy, this phenomenon will...
Abstract Double high water and double‐peak flood current were observed in Daya Bay (DYB), China, which is a shallow, mixed, mainly semidiurnal‐tide dominated bay with micro to mesotidal range. Harmonic analysis reveals that the quarter especially sexta‐diurnal constituents are getting much stronger as tides propagating into bay. The astronomical tides‐induced tidal asymmetry yet dominant at entrance but overtaken by end of Both M 4 6 tide meet requirement proposed previous studies still...
