摘要
采用多频段阻尼控制策略可抑制风光储综合能源系统接入电网导致的多频振荡现象。搭建采用多频段阻尼控制策略的风光储综合能源系统的数学模型,基于特征值分析法分析风光储综合能源系统的小干扰稳定性。最后,为验证采用多频段阻尼控制策略可实现风光储综合能源系统在小干扰下可稳定可靠运行,利用Matlab/simulink搭建了仿真模型并进行分析。仿真实验结果表明:风光储综合能源系统中储能装置采用多频段阻尼控制策略时,可增加不同频段的阻尼能力,有效抑制多频段振荡,实现小干扰稳定。
The multi-band damping control method of energy storage can suppress the multi-band oscillation of hybrid photovoltaic/wind power generation system with storage bank(HPWS).This paper establishes the mathematical model for HPWS with the multi-band damping control.And based on the proposed mathematical model,the small signal stability of HPWS is analyzed by eigenvalue method.Finally,a simulation model is built by Matlab/simulink to verify that the HPWS is stable and reliable with multi-band damping control method.The simulation results show that the multi-band damping control for the energy system increases the damping capacity and suppress the multi-band oscillation of HPWS.Hence,the multi-band damping control can ensure that the HPWS is stable and reliable operation.
