Research on multi-mode virtual inertial control of DC microgrid energy storage
摘要
Abstract
Enhancing the inertia of a direct current(DC)microgrid is a key issue to prevent the induction of DC voltage oscillations caused by the introduction of constant power DC loads.Considering the differences in the required supplementary power response rates under various voltage change rates,this paper first proposes a multi-mode virtual inertia control strategy for the energy storage battery terminals of the DC microgrid,using linear and exponential modes to provide inertia power at different rates,thereby reducing DC voltage fluctuations.Secondly,the equivalent virtual capacitance expressions for both modes are derived,establishing a dynamic relationship between the virtual capacitance and voltage adjustment.Finally,a simulation model of a DC microgrid system with energy storage is constructed to verify the effectiveness of the proposed control strategy in supporting DC voltage stability.关键词
