The modern power system is becoming more complicated due to the ever increasing penetration of electronics, which referred as a power-electronics-dominated (PEDS). In this case, analysis, control, and operation entire should tone with energy-paradigm transition pace, where challenges be properly tackled. After brief introduction grid-connected converters, article explores stability PEDSs, especially on low inertia issue multitimescale characteristics, well dynamics when connected weak grids....
The photovoltaic (PV) systems are being required to support the grid more flexibly than ever before.One of emerging demands is frequency regulation, including virtual inertia control (VIC) and damping (FDC).To achieve full-range i.e., deal with under-frequency over-frequency issues, power reserve necessary for PV systems, which should be properly utilized realize optimal support.In this context, a novel coordination strategy VIC FDC in proposed paper.According relevant codes, key indices...
State-of-charge (SOC) estimation of lithium-ion (Li-ion) batteries with good accuracy is critical importance for battery management systems. For the model-based methods, electrochemical model has been widely used due to its and ability describe internal behaviors battery. However, uncertainty parameters lack correction from voltage also induce errors during long-time calculation. This paper proposes a particle filter (PF) based method estimate Li-ion batteries’ SOC using model, sensitive...
Frequency security is one of the challenges for power grid penetrated by renewable energy systems (RESs). Virtual inertia provision from RESs considered to be efficient support frequency enhancement. How estimate nadir rapidly and accurately crucial online allocation RESs. This paper develops a generic average system (G-ASF) model at first. The low-order speed governing SG proposed enhance accuracy flexibility G-ASF model. Then, based on model, an strategy grid-connected under constraint...
Integrating the sharing economy and power industry is of positive significance for development energy market. With market transforming from a traditional vertical structure to an interactive competitive structure, users' roles need change, along with supply demand interacting more frequently. Thus, centralized optimization method single source can hardly reveal complex multi-entity behavior multi-energy coupling. Therefore, this paper establishes distributed electrical-gas-thermal mechanism...
In power electronics-dominant systems (PEDSs), the declining-inertia issue is one of most significant challenges to tackle. The inertia emulation from DC-link capacitors cost-effective and application-friendly solution enhance system inertia. Although virtual control capacitor supports grid frequency with a relatively long-term effect, it affects dynamic converter at multiple timescales. turn, maximum effective limited by operation condition converter. Thus, properly design control, dynamics...
Grid frequency support, e.g., by the virtual inertia control (VIC), of photovoltaic (PV) systems, is more demanded than ever before. To achieve full-range support (i.e., to tackle under- or overfrequency issues), power reserve necessary for PV systems. Accordingly, a (PRC) method based on maximum point tracking (MPPT) adopted in this article, referring as MPPT-PRC. It measures real-time available (MAP) periodically, being independent physical sensors and burdensome computation. However, MAP...
Abstract Purpose Periodontitis-associated bacteria, such as Porphyromonas gingivalis and Fusobacterium nucleatum , are closely linked to the risk of oral squamous cell carcinoma (OSCC). Emerging studies have indicated that another common periodontal pathogen, Prevotella intermedia ( P. ), is enriched in OSCC could affect occurrence progression OSCC. Our aim determine effects on role antibiotics reversing these effects. Methods In this study, a murine xenograft model was established, mice...
Online monitoring of battery impedance is increasing interest as it brings rich information for state estimation and fault diagnosis, however, the existing techniques are limited by high implementation costs poor accuracy. This letter addresses challenges proposing a novel two-stage optimization framework to form binary sequence with optimal power proportion in specified harmonics fast measurements. The optimized finite amplitude levels can greatly simplify implementation, also spectrum has...
Hereditary gingival fibromatosis (HGF) is a rare, benign disorder characterized by slowly progressive fibrous overgrowth of the gingiva. To date, two loci have been mapped in familial cases with autosomal dominant non‐syndromic HGF: GINGF (MIM 135300) on chromosome 2p21‐p22 and GINGF2 605544) 5q13‐q22. Of loci, only SOS1 ( son sevenless one , MIM 182530) gene underlying locus has identified. Ascertainment large Chinese family allowed mapping novel to 2p22.3‐p23.3, GINGF3. Haplotype...
Due to their fast response and strong short-term power throughput capacity, electric vehicles (EVs) are promising for providing primary frequency support grids. However, due the complicated charging demands of drivers, it is challenging efficiently utilize regulation capacity EV clusters stable grid. Accordingly, this paper proposes an adaptive strategy constrained by charging-behavior-defined operation area. First, forced boundary determined according driver's behavior, based on this, area...
Abstract Background Oral microbial dysbiosis contributes to the development of oral squamous cell carcinoma (OSCC). Our previous study showed that Prevotella intermedia ( P . ) were enriched in mucosal surface, plaque, and saliva patients with OSCC. Intratumoral microbiome could reshape immune system influence various tumors. However, invasion status human OSCC tissues by pathway through which intratumoral potentiates tumor progression remain unexplored. Methods or normal was detected FISH....
The still increasing penetration of renewable energy demands more from the distributed generations (DGs), e.g., grid-friendly PV systems, to maintain entire system stability. One requirements is power reserve, where systems should regulate output flexibly instead solely being a generating unit. To achieve this paper proposes an event-triggering reserve control (PRC) for three-phase two-stage systems. It works periodically with two operating modes - maximum mode (MPM) and (PRM). MPM at...
