一种用于直流配电网的储能系统下垂控制方法
摘要：
一种用于直流配电网的储能系统下垂控制方法，包括稳态下垂控制和暂态惯性控制，步骤为：计算稳态下垂控制的稳态参考电流偏离值△I0REF1，暂态惯性控制的暂态参考电流偏离值△I0REF2、参考电流偏离值△I0REF和实际电流参考值I*0REF；将实际电流参考值I*0REF减去实际电流值I0，得到电流偏差△I0，经过PI控制策略产生调节信号△I'0；调节信号△I'0经过PWM调制，产生驱动信号驱动储能双向变换器。
摘要（英）：

The invention discloses an energy storage system droop control method used for a direct-current power distribution network. The energy storage system droop control method comprises steady state droop control and transient state inertia control, and comprises the following steps: calculating steady state reference current deviation value delta I0REF1 of steady state droop control, transient state reference current deviation value delta I0REF2 of transient state inertia control, reference current deviation value delta I0REF and actual current reference value I*0REF; subtracting actual current value I0 from the actual current reference value I*0REF to obtain current deviation delta I0, and generating an adjusting signal delta I'0 through a PI control strategy; and carrying out PWM modulation on the adjusting signal delta I'0 to generate a driving signal so as to drive an energy storage bidirectional transducer.
