Control and Simulation of Autonomous Hybrid Wind-PV System

This paper designs the control strategies for an autonomous hybrid wind-PV system, and by means of the time-domain simulation verifies the control strategies. The Simulation system consists of two direct-drive permanent magnet synchronous generators, photovoltaic and energy storage devices and related converters. A mathematical model of the system and the corresponding control strategies for direct-drive permanent magnet generators, photovoltaic converter, charge-discharge converter of energy storage, as well as grid side inverter are established in the paper, and by means of the time-domain simulation method, dynamic simulation is done for the related control strategies of the system. The results indicate the designed control strategies in the paper are both correct and feasible.
