摘要
As an approach to making distributed energy resources with virtual inert a, the virtual synchronous generator control strategy plays a significant role in the micro-grid stability. On the basis of theoretical derivation and analysis of vi dual synchronous generator control and micro-grid, an overall virtual synchronous generator control strategy of distributed energy resources inverter was proposed to improve the stability of micro-grid. The outside control of distributed inverter was constructed by using synchronous generator's rotor motion equation, primary frequency regulation feature and the delay characteristic of reactive power regulation. And the bottom control was adopted by the vector relationship of synchronous generator grid-connected to grid. Finally, a simple micro-grid digital simulation system based on Matlab/Simulink was built, and the results show that the proposed control method has an important effect to support the frequency stability of micro-grid.
