Power quality enhancement in islanded microgrids via closed-loop adaptive virtual impedance control
Institute of Electrical and Electronics Engineers (IEEE) - - 2023
Yang Wang, Junmiao Tang, Jiandong Si, Xianyong Xiao, Peter Zhou, Jinshuai Zhao
The high proportion of nonlinear and unbalanced loads results in power quality issues in islanded microgrids. This paper presents a novel control strategy for harmonic and unbalanced power allocation among distributed generators (DGs) in microgrids. Different from the existing sharing strategies that allocate the harmonic and unbalanced power according to the rated capacities of DGs, the proposed ...... hiện toàn bộ
A dynamic-model-based fault diagnosis method for a wind turbine planetary gearbox using a deep learning network
Institute of Electrical and Electronics Engineers (IEEE) - - 2022
Dongdong Li, Yang Zhao, Yao Zhao
AbstractThe planetary gearbox is a critical part of wind turbines, and has great significance for their safety and reliability. Intelligent fault diagnosis methods for these gearboxes have made some achievements based on the availability of large quantities of labeled data. However, the data collected from the diagnosed devices are always unlabeled, and the acquisi...... hiện toàn bộ
Robust fault analysis in transmission lines using Synchrophasor measurements
Institute of Electrical and Electronics Engineers (IEEE) - Tập 3 - Trang 1-13 - 2018
Rajaraman P., Sundaravaradan N.A., Mallikarjuna B., Jaya Bharata Reddy M., Mohanta D.K.
As more electric utilities and transmission system operators move toward the smart grid concept, robust fault analysis has become increasingly complex. This paper proposes a methodology for the detection, classification, and localization of transmission line faults using Synchrophasor measurements. The technique involves the extraction of phasors from the instantaneous three-phase voltages and cur...... hiện toàn bộ

AbstractIn this paper, a virtual synchronous generator (VSG) controller is applied to a hybrid energy storage system (HESS) containing a battery energy storage system and supercapacitor storage system for maintaining the frequency stability of an isolated microgrid. The microgrid contains a photovoltaic generation system and a diesel generator in addition to the HE...... hiện toàn bộ
Bi-level stackelberg game-based distribution system expansion planning model considering long-term renewable energy contracts
Institute of Electrical and Electronics Engineers (IEEE) - Tập 8 Số 1 - 2023
Hongjun Gao, Renjun Wang, Shuaijia He, Zeqi Wang, Junyong Liu
AbstractWith the deregulation of electricity market in distribution systems, renewable distributed generations (RDG) are being invested in by third-party social capital, such as distributed generations operators (DGOs) and load aggregators (LAs). However, their arbitrary RDG investment and electricity trading behavior can bring great challenges to distribution syst...... hiện toàn bộ

Accurate classification of power quality disturbance is the premise and basis for improving and governing power quality. A method for power quality disturbance classification based on time-frequency domain multi-feature and decision tree is presented. Wavelet transform and S-transform are used to extract the feature quantity of each power quality disturbance signal, and a decision tree with classi...... hiện toàn bộ
Maximum production point tracking method for a solar-boosted biogas energy generation system
Institute of Electrical and Electronics Engineers (IEEE) - Tập 6 - Trang 1-13 - 2021
Jialin Chen, Ruijiang Yang, Da Xu, Bin Zhou, Yifang Jin
Low biogas yield in cold climates has brought great challenges in terms of the flexibility and resilience of biogas energy systems. This paper proposes a maximum production point tracking method for a solar-boosted biogas generation system to enhance the biogas production rate in extreme climates. In the proposed method, a multi-dimensional R–C thermal circuit model is formulated to analyze the di...... hiện toàn bộ
Battery energy storage-based system damping controller for alleviating sub-synchronous oscillations in a DFIG-based wind power plant
Institute of Electrical and Electronics Engineers (IEEE) - - 2023
Neevatika Verma, Narendra Kumar, Rajeev Kumar
AbstractThis paper presents the issue of the Sub-synchronous resonance (SSR) phenomenon in a series compensated DFIG-based wind power plant and its alleviation using a Battery Energy Storage-based Damping Controller (BESSDCL). A supplementary damping signal is developed considering the angular speed deviation and is incorporated into the BESS c...... hiện toàn bộ
