Study on the value of "wind-light-fire" bundled coal electricity delivery in large clean energy base

Although there is widespread shortage in northwest China, it has abundant wind, light and coal resources. It is an important way to solve the contradiction between new energy and load distribution to bundle "wind and fire" power through uHV channel. With the goal of abandoning wind and light, the optimization model of "wind, light-fire" coupling pre-day is built to determine the optimal output of coal power units in the process of "wind-light-fire" baling, and then calculate the economic value and environmental value of coal power units to promote the consumption of new energy. The results show that through the "wind-light-fire" baling delivery, the power generation is reduced, the benefits of new energy delivery is increased, and the carbon dioxide emissions of coal power units are reduced.
