title = "Study and development of a modified droop control strategy for autonomous microgrids",
abstract = "This paper develops a control strategy for converters in low voltage single phase isolated microgrids. Droop control technique for low voltage is used to control the active power as function of the voltage amplitude, and reactive power as function of frequency deviation. This control suppresses the use of physical communication between the power converters by simply local measurements, allowing its connection to the system without adjustment needs. Some concepts as microgrids and types of inverters connected as grid forming, providing and supporting inverters are introduced. It is demonstrated the droop control, and it is individualized for low-voltage systems, where it is more convenient to use active power as function of the magnitude of the voltage. A novel modified droop control equation is proposed to compensate the voltage drop at line resistance. The validity of this new approach is proven by simulations that compare both droop types and presents the effective improvement in active power-sharing and voltage regulation at common bus.",
