Abstract
A decentralized voltage control method for a microgrid based on nonlinear state observers, comprising the steps of step), establishing a large-signal model of distributed generations, a connection network and impedance-type loads in the microgrid; step), establishing a Luenberger-like nonlinear state observer for each distributed generation; step), estimating the dynamic characteristics of other distributed generations in real time based on the local measured values of each distributed generation; and step), implementing the decentralized voltage control based on the control requirements of reactive power sharing and voltage restoration. The control method realizes the voltage control of microgrid based on the decentralized state observers, which does not rely on communication transmission or remote measurement and avoids the adverse effects of communication latency and data drop-out on the control performance.
