title = "Small AC signal droop based secondary control for Microgrids",
abstract = "The well-known active power-frequency and reactive power-voltage amplitude droop control is widely used in the coordinative control of parallel inverters in Microgrids. However, this conventional droop method may cause deviation on the frequency and voltage amplitude, which will affect the accuracy of power supply. This paper proposes a novel secondary control method to compensate this deviation. This method is based on the control of a small AC voltage signal, which serves as a communication link among the parallel inverters. The output power of the inverter can be automatically regulated by establishing a droop relationship between the frequency of the small AC signal and the bias of the inverter's droop characteristics. Through this method, frequency and voltage amplitude deviation can be eliminated and power sharing can be realized among the parallel inverters. Simulation and experimental results are provided to prove the effectiveness of the proposed control method.",
