Abstract

Aiming at the problem of the intermittency of distributed generation lead to the micro-gridpower instability

establishes (virtual synchronous generator

VSG) mathematical model based on thecontrol method of VSG technology

designs a feedback controller based on current

voltage and powercontrol

puts forward a new-type VSG control strategy

realizes uniform distributing control for activepower and reactive power of micro- grid by controlling the dynamic characteristic of distributedgenerations (DGs)

by Matlab/Simulink simulation

verifies the validity of the proposed controlalgorithm. The result shows that the control strategy has important significance to suppress fluctuationof new energy sources and to improve the quality of power energy.
