摘要
Abstract
In response to the increasingly prominent issue of wide-frequency resonance in power grids with high penetration of renewable energy integration,a wide-frequency resonance damping enhancement strategy based on energy storage converters is proposed.An adaptively adjusted virtual impedance is introduced into the control loop in this strategy,which enables the energy storage converter to effectively absorb the resonance energy induced by other converters at the point of common coupling(PCC)while completing the predetermined power dispatch task,thus achieving the effect of wide-frequency resonance damping.Firstly,a control strategy for the energy storage converter is constructed,and an impedance model is established based on virtual synchronous machines.Secondly,a resonance damping control method based on the active damping principle is proposed.Finally,a design method for adaptive adjustment of virtual impedance is proposed,and its impact on the stability of other converters at the PCC is analyzed.Experimental results show that the method proposed has good suppression capability for wide-frequency resonance issues.关键词
