With the rapid expansion of the development and utilization of wind power, the volatility of power and limited power delivery problems have brought new challenges to the consumption and utilization of wind power. In view of the water-wind-storage complementary delivery mode in northwest China, a multi-objective model is built considering both the utilization rate of power transmission channel and the revenue of complementary system, based on which the energy storage operation strategy under the time-of-use price is proposed. Then, this method is applied to a multi-energy complementary base in the upper reaches of the Yellow River. By comparing and analyzing the control strategies of the two large complementary systems, it is proved that the complementary system play an important role in improving the utilization rate of the power delivery channel, absorbing the wind curtailment and improving the operating income. Finally, results show that the uncertainty degree of wind power, the time-of-use price and power transmission channel capacity have great influence on the system complementary effect. This method can provide technical support and reference for the planning and operation of the new energy and hydropower complementary system in the future.
