To improve the quick frequency response effect of photovoltaic power generation system and solve the problems of power distribution error and power oscillation occurred during conventional droop control
a selfadaptive transient droop control scheme is proposed in this paper. This scheme can automatically adjust the active power droop coefficient according to the output power
and introduce a transient factor
to reduce the fluctuation of power generation. In the self-adaptive transient droop control
the introduction of transient components reduces the dynamic response time
reduces the vibration amplitude of output power
and improves the dynamic performance of drooping control. The MATLAB/Simulink simulation results show that
the self-adaptive transient droop control scheme proposed in this paper can effectively reduce the regulation amount of output power
avoid the wide range regulation of photovoltaic inverter
