The scheduling optimization of asynchronous interconnection can ensure the stable operation of the back-to-back DC transmission system,but different scheduling periods may affect the balance and stability of the scheduling optimization,hence,a scheduling optimization method for the asynchronous interconnection of the back-to-back DC transmission system in different stages is proposed.The equivalent circuit of the back-to-back DC transmission system is analyzed,and the voltage val-ue output by the rectifier is calculated according to the equivalent circuit of the rectifier,and the output model of the back-to-back DC transmission system is constructed.In power generation and transmission stage,the asynchronous interconnection scheduling constraints and optimization algorithm of DC transmission system are designed,and the asynchronous interconnec-tion scheduling optimization of DC transmission system is realized.The experimental results show that the output power of the DC transmission system is always stable between 20 kW and 42 kW,which can stably improve the balance and stability.
