In order to improve the utilization of renewable energy and reduce the damage caused by the volatility of renewable energy, it is necessary to further study the multi-energy combined operation strategy. In this paper, a combined operation mode of wind power, gas-fired power and pumped storage is put forward. In this mode, wind power is the main source while gas-fired power and pumped storage act as an adjustment to smooth wind power output. The model takes the maximum benefit of joint operation as the objective and adopts mixed integer linear programming. Through an example, the economic benefit of the combined operation mode of wind-gas-pumped storage is calculated. The results show that this operation mode not only improves the utilization of wind power, but also improves the efficiency of power grid operation.
