Abstract

Due to the increasing energy demands in microgrids (MG), the need for parallel-connected distributed generations (DG) to supply the load required by customers has been increased. An interfacing inverter connects the distributed generation units to the microgrid. The operating performance of a microgrid is largely determined by the interfaced inverter. For stable and reliable operation of the microgrid, the inverters of the distributed generation units have to be controlled for active and reactive power sharing. In this paper, active power–frequency (P–F)/reactive power-amplitude (Q–V) droop control is used to control the parallel-connected inverters in a microgrid operated in islanded mode. The inverter frequency and voltage droop control should keep the frequency and voltage within the allowable limits when operating on an islanding grid mode. Voltage and frequency Droop control for parallel inverters is implemented, and each inverter provides proportionate load sharing. MATLAB/Simulink is used to model the droop control of a parallel-connected inverter. Furthermore, the findings show that droop control has a substantial influence on balancing the voltage magnitude, frequency, and active power sharing within the limit.
