Adaptive Control of Grid-forming Energy Storage Converters Considering SOC and Frequency Recovery
摘要
Abstract
Under the backdrop of"dual carbon"goals,the new power system dominated by new energy faces such challenges as insufficient rotational inertia,inadequate damping and significant frequency fluctuations.For this rea-son,an adaptive control strategy of grid-forming energy storage converter considering the state of charge of energy storage and frequency recovery is proposed.First,the small signal model of grid-forming energy storage converter is set up in this paper,and the influence of virtual inertia and damping coefficient on system characteristics is analyzed.Then,the virtual inertia and damping coefficient are designed using root locus analysis and dynamic response.On this basis,a regression function is introduced to construct a control factor among SOC,virtual inertia and damping co-efficient.The energy storage state of charge and frequency recovery are included in the adaptive influencing factors of virtual inertia and damping,ensuring real-time adjustment of inertia and damping coefficient disturbances while ensuring the safety of the energy storage device.Finally,a simulation model is constructed in MATLAB/Simulink and both feasibility and effectiveness of the proposed strategy are verified by the simulation result.关键词
