Grid syncronization, PLL algorithm, Reduced order observer, RST controllerAbstract
In this paper, phase locked loop or PLL algorithm for grid syncronization is investigated. The proposed technique is implemented with reduced order observer of prostoperiodic disturbances and RST controller. Algorithm control loop is implemented in continuous and discrete time domain.
