Energy storage voltage source active support method and device with power self-adaptive adjustment

The invention relates to an energy storage voltage source active support method with power adaptive adjustment. The method comprises the following steps: S1, acquiring an output reference frequency of a power distribution network inverter; s2, compensation power is calculated, and the compensation power comprises at least one of a first compensation value, a second compensation value, a third compensation value and a fourth compensation value; S3, the maximum output power of the energy storage system and the sum of the inverter output active power rated value and the compensation power are compared, and the minimum value of the maximum output power and the sum of the inverter output active power rated value and the compensation power is taken as the output power of the energy storage system. 本发明涉及一种功率自适应调节的储能电压源化主动支撑方法，包括：S1、获取配电网逆变器输出参考频率；S2、计算补偿功率，所述补偿功率包括第一补偿值、第二补偿值、第三补偿值、第四补偿值中至少一者：S3、比较储能系统最大输出功率、逆变器输出有功功率额定值与补偿功率之和，取两者中的最小值为储能系统输出功率。
