摘要：

The voltage droop control technology is commonly adopted to control the power sharing between parallel energy storage units in island dc microgrid for its low cost on the control and communication system, but a large number of voltage and current sensors are needed in the traditional droop control method. An improved droop control method for reducing current sensors is proposed. To achieve voltage droop control, the power transferred by converters is analyzed and calculated without detecting output current, then, a function of converter input/output variables and control variables which is proportional to the output power of converters is adopted in the improved droop controller. Verification results are provided to validate the effectiveness and reasonability of the proposed control method.
