Abstract：This study explores a new wind-solar-storage integrated energy system based on a wind-heat unit,incorporating photovoltaic-thermal(PV/T)integration technology and energy storage devices.Using Matlab/Simulink software,a dynamic simulation model of the system was constructed,taking the demonstration base in Baiyin City,Gansu Province,as an example to preliminarily assess the system's feasibility.The results show that the photoelectric efficiency and electricity generation of the photovoltaic-thermal(PV/T)system increase by approximately 14.4%and 11.2%,respectively,compared to conventional photovoltaic panels.During the simulation period,the temperature of the thermal storage tank rose by 13.6 K,and the indoor temperature increased by 6.7 K,demonstrating that this technology effectively meets the requirements for heating conditions and indoor comfort.The average coefficient of performance(COP)for the new wind-solar storage integrated energy system is 2.83,indicating high energy efficiency.
