Energy-storage hydroelectric generation system

Abstract

The invention discloses an energy-storage hydroelectric generation system which comprises an upper pool, a lower pool positioned downstream, a hydroelectric generator and a water pump, wherein a water inlet and a water outlet of the hydroelectric generator are respectively connected with the upper pool and the lower pool; a water inlet and a water outlet of the water pump are respectively connected with the lower pool and the upper pool; the hydroelectric generation system further comprises a control device, and a wind driven generator or / and a solar generator which is / are used for providing electric energy needed by the work of the water pump, wherein the control device is used for controlling the work of the water pump according to the generated energy of the wind driven generator or / and the solar generator as well as the water level of the upper pool. By adopting the embodiment of the energy-storage hydroelectric generation system, as the wind driven generator can be used for providing electric energy needed by the work of the water pump, and the water level of the upper pool is maintained to be more stable, the hydroelectric generator has enough water for generating electricity when in the peak period of electricity consumption, and the electricity consumption demand in the peak period of electricity consumption can be met.

Description

technical field [0001] The invention relates to the technical field of hydropower generation, in particular to an energy-storage hydropower generation system that uses wind energy or solar energy as hydropower to provide energy storage. Background technique [0002] As a non-polluting energy source, hydroelectric power accounts for about 21% of the total electrical energy, but hydroelectric power has some shortcomings. On the one hand, because hydropower itself depends on water resources, it is restricted by geographical conditions, and only in areas rich in water resources can a hydropower system be built; Electric energy, cannot provide sufficient electric energy during dry season. There are often peaks and valleys in electricity consumption, and it is difficult to adjust the peaks and valleys of electricity consumption. For example, electricity consumption during the day is greater than that at night. When there is enough water, hydroelectric power can run at full capa...

Problems solved by technology

However, due to the influence of seasonality and power consumption cycle; when the power consumption is low, when the power provided by the hydroelectric power generation system is insufficient, energy storage cannot be carried out.
