Light-wind-water complementary type water pumping and energy storing power generation peak adjusting device

Abstract

The invention relates to a light-wind-water complementary type water pumping and energy storing power generation peak adjusting device which belongs to the field of development and utilization of newenergy sources. The device is characterized in that an upper water storage reservoir is built on the mountain top in a mountain area depending on a high mountain; a lower water storage reservoir is built in a valley; the mountain slope exposed to the sun in the area is provided with a solar energy photovoltaic cell board; wind power generation fields are arranged on the upper water storage reservoir on the mountain top and the position at periphery with more favorable wind current condition; a water pumping and energy storing power generation peak adjusting power station is arranged between the upper water storage reservoir and the lower water storage reservoir; the lower water storage reservoir is provided with a water pump station; a water inlet pipe and a water outlet pipe of the waterpumping and energy storing power generation peak adjusting power station are respectively communicated with the upper water storage reservoir and the lower water storage reservoir; and a water inlet pipe and a water outlet pipe of the water pump station are respectively communicated with the lower water storage reservoir and the upper water storage reservoir. The invention can carry out large-scale development and storage in such a way that solar energy and wind energy are converted into water energy and lead a traditional water pumping and energy storing hydropower station to finish peak adjustment on a power grid under the condition of not consuming or consuming less electric energy of the power grid.

Description

technical field [0001] The invention relates to photovoltaic, wind power and water power utilization technologies, and at the same time relates to peak-shaving technology of pumped-storage power generation. Background technique [0002] The worldwide energy shortage and local energy crisis have affected and restricted the sustainable development of human society and economy to a certain extent. At the same time, due to the excessive dependence of human beings on traditional mineral energy and the extensive use of fuel energy, the resulting greenhouse effect and serious pollution of the atmospheric environment have made the human living environment face severe challenges. In order to change this situation, human beings have to explore new environmentally friendly and clean energy sources. Vigorously developing the development and utilization of energy sources such as solar energy, wind energy, and water energy has become an important way for countries all over the world to s...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that solar energy and wind energy cannot be continuously and stably supplied and the power consumption of the pumped storage hydropower station itself is too large for the power grid. Large-scale development and storage of wind energy in the form of conversion into water energy can also enable the traditional pumped storage hydropower station to complete the peak regulation of the grid without consuming or consuming less power from the grid, so as to maximize the power of the grid.
