Stability of voltage and frequency control in distributed generation based on parallel-connected converters feeding constant power loads
(2007) 17(3). p.38-46- Abstract
- In this paper stability and dynamic properties of voltage and frequency droop control of power electronic converters are investigated for a distributed generation system. Droop control is utilized to share active and reactive power among the source converters. The voltage and frequency controllers are designed so that stand-alone converter operation feeding constant power loads performs satisfactory. These controllers are adapted to mimic the behaviour of present rotating generators connected directly to the power system, for seam-less transfer between island and grid-connected modes of operation. The target system for the analysis is a stand-alone system to which three power electronic converters and one rotating generator could be... (More)
- In this paper stability and dynamic properties of voltage and frequency droop control of power electronic converters are investigated for a distributed generation system. Droop control is utilized to share active and reactive power among the source converters. The voltage and frequency controllers are designed so that stand-alone converter operation feeding constant power loads performs satisfactory. These controllers are adapted to mimic the behaviour of present rotating generators connected directly to the power system, for seam-less transfer between island and grid-connected modes of operation. The target system for the analysis is a stand-alone system to which three power electronic converters and one rotating generator could be connected (Fig. 1). Small-signal and switch-mode, time-domain simulation results of a threeconverter distributed generation system facilitating stand-alone operation verify the operation. Simulation and experimental results of a three-converter stand-alone system, with and without a rotating generator present, are also included for verification. (Less)
