Impedance modeling of a permanent magnet synchronous generator (PMSG)-based wind energy conversion system (WECS) usually ignores the machine-side dynamics, instead, is simplified as constant power source, while merely keeping detailed grid-side converter model. This simplification mainly based upon intuition that dc-bus capacitor large enough so machine- and dynamics can be decoupled. However, probably does not hold in practice since there always tendency to minimize size achieve smaller...
Increasing integration of inverter-based resources (IBRs) brings new power system stability challenges. Virtual synchronous generator control-based IBRs (VSG-IBRs) are expected to take the role some traditional SGs and reconstruct future system. Although VSG control imitates main dynamics SG, impact VSG-IBRs on can be different thus worth a detailed study. In this paper, in two test systems substituted by investigate impacts VSG-IBR substitution locations, parameters, distributed or...
This paper presents a comprehensive review of the supplementary damping controllers (SDCs) proposed for mitigation sub-synchronous interaction (SSI) between doubly-fed induction generator-based wind parks (DFIG-WPs) and series capacitor compensated grids. First, terms control (SSCI) generator effect (IGE) are clarified by delineating their occurrence conditions instability mechanisms in DFIG-WPs. Then, generic design testing framework SDCs is as basis including selection adjustment key...
Abstract Fasting blood glucose (FBG) and glycosylated hemoglobin (HbA1c) are key indicators reflecting control in type 2 diabetes mellitus (T2DM) patients. The purpose of this study is to establish a predictive model for changes T2DM patients after 3 months treatment, achieving personalized treatment.A retrospective was conducted on real-world medical data from 4 cities Sichuan Province, China January 2015 December 2020. After preprocessing, inputting, sampling, feature screening, 16 kinds...
Hybrid ac/dc distribution grids are gaining popularity due to their potential conflate the benefits of both ac and dc grids. However, complex structure these imposes new challenges in power flow (PF) calculations multiple interconnections, variety converter operations, constant loads. This paper proposes a unified PF algorithm incorporating different types dc/dc converters. The proposed approach is based on Newton Raphson (NR) uses Modified-Augmented-Nodal-Analysis (MANA) formulation....

A body area network (BAN) as one branch of Sensor Networks, is an inter-disciplinary which holds great promises for revolutionising the current health care systems. BAN combines real-time updating biomedical data with continuous and dynamic monitoring closely. number intelligence sensors can be integrated into a wireless system, system used prevention, diagnosis timely treatment various medical conditions. In this article, we propose fusion technique based on signals. This proposed solution...
Logistics monitoring is a fundamental application that utilizes RFID systems to manage numerous tagged-objects. Due the frequent rearrangement of tagged-objects, fast RFID-based tracking approach highly desired for accurate logistics distribution. However, traditional usually take tens seconds interrogate hundreds tags, not mention time delay involved locate all which severely prevents from in-time tracking. To address this issue, we reduce problem domain by first distinguishing motion...
Variable-fidelity (VF) surrogate models have been widespreadly applied to aerospace structural design and optimization problems with multiple objectives alleviate the cost. To enhance performance of existing multi-objective algorithms based on VF model, a variable-fidelity hypervolume expected improvement (VF-HVEI) method is proposed. Co-Kriging model utilized replace computational expensive objective functions in proposed method, it sequentially updated VF-HEVI during process. The infilling...
Wind-farm-side modular multilevel converters (WFMMCs) used in converter based high-voltage direct current (MMC-HVDC) transmission systems must be able to control the AC grid voltage offshore wind farms. Different strategies can significantly affect dynamic characteristics of WFMMCs. However, existing studies have not provided a general methodology controller parameter design, and few comparative been conducted on performance under varying operating conditions as well effects different modes...
