摘要
Abstract
The equivalent output impedance of paral el inverters could be designed to be inductive, resistive or resistance and inductance. With reasonable control methods and suitable design of parameters, under the above three kinds of equivalent output impedance form, the control of paral el inverters could be realized. To further study the paral el-control strategy, the model based on two paral el inverters was established through the introduction of virtual impedance. The droop control strategy based on the capacitive equivalent output impedance was deduced through the output impedance of the inverters which were designed to be capacitive. The robust droop control strategy based on capacitive equivalent output impedance was proposed. The power sharing characteristics under the capacitive, inductive, and resistive equivalent output impedance were compared. It shows that the multiple-inverter paral el system under the capacitive equivalent output impedance has better performance. In the photovoltaic inverter paral el system platform with two 2kVA inverters, the crorrection of robust droop control strategy based on capacitive equivalent output impedance was verified.关键词
