Abstract：Although the northwest of China is sandy and deserted,it is rich in wind,sunlight and coal resources.The bundled transmission of"wind-photovoltaic-fire"power through ultra-high-voltage channel is an important way to solve the contradiction between new energy and load distribution.With the goal of minimizing wind and light rejection,we constructed a multi-timescale coupling optimization model of"wind-photovoltaic-fire"bundled transmission before the day and within the day to determine the optimal output of coal-fired power units.Then,the economic and environmental values of coal power units to promote new energy consumption are calculated.The results show that the bundling of"wind-photovoltaic-fire"reduces the amount of wind and photovoltaic abandoned power generation,increases the income of green certificate for new energy export,and reduces the carbon dioxide emission of coal power units.
