A method for large-scale and stable delivery of wind power generation

Abstract

The invention discloses a method for large-scale stable delivery of wind power generation. In the method, wind power is taken as the major part, pumped storage is used as an energy storage adjusting means for the wind power, and thermal power is used for supplementation, so that large-scale stable delivery of wind power generation is realized; when more solar power exists around, light energy can be delivered in a complementation with wind power, then the pumped storage is used for storing, and the thermal power is used for adjusting the storage or supplementation. In the method, the wind power is taken as the major part, the electric energy in other forms is used for supplementing the wind power, and rational dispatching is performed through a power transmission line, so that the large-scale stable delivery of wind power generation is realized. The development of wind power generation is promoted. The method has extremely obvious direct power generation benefit, is possibly developed together with the wind energy at the areas such as Mongolia and the like, has extremely remarkable indirect environmental benefit and also contributes to national energy safety. The large-scale wind energy utilization is facilitated; the coal-generated power at the delivery end can be promoted; the economy of the power transmission line is improved; the dispatching of a receiving power grid is facilitated; and the method has the benefit in the aspect of environmental protection by using clean and renewable energy.

Description

technical field [0001] The invention relates to a method for large-scale and stable delivery of wind power generation, and belongs to the technical field of power station combination. Background technique [0002] Both wind power and solar power are relatively economical and pollution-free power generation methods, but these two power generation methods will be affected by the natural environment and cannot guarantee continuous and stable power supply at full load. In my country's vast plains and Inner Mongolia grasslands, there are extremely rich wind resources. However, due to the influence of the weather, sometimes the wind is very strong, sometimes the wind is very small, or even no wind, so it is difficult to ensure continuous and stable power supply to the grid for wind power generation. Wind energy is a non-polluting and clean energy. It uses the energy of the wind to drive the wind wheel to rotate, and then the wind wheel drives the generator to generate electricity...
