R/glmnet has been successfully applied to jointly mapped multiple quantitative trait loci for linkage analysis, along with statistical inference candidates nonzero genetic effects using R/lm normally distributed traits, R/glm discrete and R/coxph survival times. In this study, we extended a genome-wide association study by means of parallel computation. A multi-locus high-throughput single-nucleotide polymorphisms was implemented in the "Multi-Runking" software written within R workspace....
The nonuniform large damping introduced by grid-forming (GFM) converters in multi-machine system could destabilize the power under disturbance, which may bring new challenges to safe operation of future system. In this letter, mathematic model GFM-penetrated considering effect is established first, and concept uniform energy further proposed clarify impact different components. Moreover, influence mechanism on transient stability revealed, implies that only part generators analysis result...
With the increasing penetration of virtual synchronous generator (VSG)-controlled inverters in renewable power system, transient stability analysis paralleled VSG system with interactions between is urgently needed. However, large damping effect brought by VSGs on relative motion still unclear, which impedes accurate evaluation system. In this article, explored recognition uniform and nonuniform effects, it found that may also destabilize under some configurations. To figure out influential...
With the increasing penetration of power converters in modern system, virtual synchronous generator (VSG) control is considered to be a promising method due its grid friendliness. However, lack clear and accurate description angle dynamics poses challenges stability analysis converter parameters design. In this article, Krylov–Bogoliubov averaging method, an effective parameter-perturbation-based analytical calculation for dissipative process, first presented characterize dynamic trajectory...
In this paper, the paralleled VSGs system's transient stability is researched with consideration of large damping effects introduced by VSG. Firstly, model considering items established, and relative motions in uniform nonuniform cases, are described second-order third-order model, respectively. On basis, behavior linear system at SEP UEP firstly investigated different selected, it's found stable trajectory may exceed during process. Furthermore, discussed for cases ones, separately. It's...
In this paper, a sub-module capacitor voltage control (SCVC) is proposed to alleviate the energy balance restriction in alternate arm converter (AAC). Considering that inductor has great impact on exchange AAC, current commutation modulation demonstrated firstly paper extend operating range. Then, process for arms further explored and derived by analytical expressions. During process, through turning-on rising, while contralateral reversely freewheeling diodes of director switches (DSs)....
With the increasing numbers of power electronic devices in system, virtual synchronous generator (VSG), which mimics motion rotational generators (RSGs), is proposed to cope with revolution system structure. However, there lacks precise angle transient descriptions, leading inaccurate stability analysis VSGs. In this paper, analytical methods for perturbation systems are introduced VSGs solve angel waveforms. The reactive control loop first considered and voltage vibration described by...
