Adaptive Mitigation Strategies for Sub-/Sup-synchronous Oscillation in Renewable Energy Power Plants and AC Power Grids Under Black/Grey Box Situations
摘要
Abstract
The interaction between renewable energy power plants and power grids has induced sub-/sup-synchronous oscillation issues,causing great challenges to the secure operation of power systems.Limited by commercial factors and complicated topologies,it is difficult to obtain a detailed model of the whole renewable energy power system,which poses challenges for analyzing and mitigating the sub-/sup-synchronous oscillation issues in real scenarios.To this end,this paper proposes a sub-/sup-synchronous oscillation mitigation scheme for renewable energy power systems under black/grey box situations.First,a coupled impedance model,which considers the implicit coupling relationship between the shunt converter and the power system,is proposed to reveal the dynamic interactions between the shunt converter and the power system.Based on the coupled power system,an adaptive coupling reshaping control strategy is proposed to reshape the coupling relationship between the shunt converter and the power system,which increases the equivalent resistance of the power grid at the target frequency and hence mitigates sub-/sup-synchronous oscillation.The proposed method updates the coupling relationship solely through online measurement and hence obviates the requirement of the detailed system model.Finally,the controller-hardware-in-loop tests verify the correctness and effectiveness of the proposed method.关键词
