摘要
Abstract
Aimed at the problem that the traditional virtual inertia control method cannot restore the DC bus voltage to its rated value at the frequency recovery stage,a virtual inertia control method using a high-pass filter is proposed.MATLAB/Simulink simulation results show that the changes in DC bus voltage can reflect the microgrid frequency in real-time,and the novel virtual inertia control strategy can ensure the frequency stability in the entire changing process.At the frequency recovery stage,the virtual inertia is reduced to accelerate the frequency recovery,providing sufficient time margin for subsequent frequency adjustment.The high-pass filter virtual inertia control method can restore the DC bus voltage to its initial value and maintain the DC bus voltage stability of the new energy storage microgrid without changing the inertia support of the super capacitor energy storage.关键词
