Abstract

In order to maximize the absorption capacity of wind power and solve the problem of wind abandonment in my country, this paper proposed an integrated energy system that combines cogeneration units, wind turbines, electric boilers and heat storage devices. Based on the established mathematical model, the system's ability to absorb wind power and the best operating mode of cogeneration units under three different operating modes were studied. The research results show that the wind power absorption capacity of the system is only 77.9% through the self-regulation of the cogeneration unit; the system's wind power absorption capacity can be increased to 92.8% by adopting the method of mutual adjustment of cogeneration units and electric boilers; and it can reach 97.3% by using the operation mode of combined adjustment of cogeneration units, electric boilers and heat storage device.
