Design and Simulation of Stand-Alone Wind-Solar Hybrid Generating System

A modularized stand-alone hybrid generating system is designed and its composition and working principle is illustrated; working principle of components of wind driven generator, photovoltaic array, storage battery and controller etc. are expounded and corresponding mathematical model is established. In addition, tracking and control measures of the maximum power point based on maximum power given method and perturbation and observation method is proposed and design of software of the system is offered. Finally, simulation of the system is studied based on SIMULINK, resulting in that the system can realize tracing and control of the maximum power point.
