Abstract

This study aims to evaluate the power-system stability and the mitigation of fluctuations in a hybrid wind/wave power-generation system (HWWPGS) under different operating and disturbance conditions. This evaluation is performed by employing a vanadium redox flow battery-based energy storage system (VRFB-ESS) as proposed. The measurement results obtained from a laboratory-scale HWWPGS platform integrated with the VRFB-ESS, operating under specific conditions, are used to develop the laboratory-scale simulation model. The capacity rating of this laboratory-scale simulation model is then enlarged to develop an MW-scale power-system model of the HWWPGS. Both operating characteristics and power-system stability of the MW-scale HWWPGS power system model are evaluated through frequency-domain analysis (based on eigenvalue) and time-domain analysis (based on nonlinear-model simulations) under various operating conditions and disturbance conditions. The simulation results demonstrate that the fluctuations and stability of the studied HWWPGS under different operating and disturbance conditions can be effectively smoothed and stabilized by the proposed VRFB-ESS.

风波混合发电一体化液流电池储能系统仿真与测量分析

本研究旨在评估风波混合发电系统(HWWPGS)在不同运行和扰动条件下的电力系统稳定性和波动缓解。这项评估是通过采用提出的基于钒氧化还原液流电池的储能系统(VRFB-ESS)来进行的。利用与VRFB-ESS集成的实验室规模HWWPGS平台在特定条件下的测量结果，建立了实验室规模的仿真模型。然后，将该实验室规模仿真模型的容量额定值扩大到兆瓦级的HWWPGS电力系统模型。通过基于特征值的频域分析和基于非线性模型仿真的时域分析，对mw级HWWPGS电力系统模型在各种运行工况和扰动条件下的运行特性和电力系统稳定性进行了评价。仿真结果表明，所提出的VRFB-ESS可以有效地平滑和稳定不同运行和扰动条件下的HWWPGS的波动和稳定性。
