Abstract

This paper presents a model of grid-connected hybrid ac/dc micro grid. The proposed system consists of a variable-speed and direct-drive wind generator, wind-side converter, solar array, dc-dc converter and grid interface inverter. All the generation units are connected to a distribution system to operate in grid-connected mode.  The grid interface inverter transfers the energy drawn from the wind turbine and PV array into the grid by keeping common dc voltage constant. Dynamic models for each system component were developed and used for steady state simulation.  The influence of the system operation was simulated at steady state in both ac and dc sides using Matlab/Simulink. The simulation results show the dynamic behaviour of the wind/PV system.
