Energy storage power generation method based on gravitational potential energy and energy storage power generation tower

Abstract

The invention provides an energy storage power generation method based on gravitational potential energy. The energy storage power generation method comprises the following steps of potential energy storage: hoisting heavy objects preset on a first bottom surface, and stacking the heavy objects into an energy storage tower, wherein the height of the energy storage tower is larger than that of the first bottom surface; and potential energy conversion: hoisting the heavy objects on the energy storage tower again, enabling the heavy objects to fall to the first bottom surface under the action of gravity, wherein in the falling process of the heavy objects, power generation equipment is driven to operate, power generation is completed, and gravitational potential energy is converted into electric energy. The heavy objects can be hoisted and stacked through a manual or mechanical hoisting method, and storage of gravitational potential energy is achieved; when power supply is needed, the heavy objects on the energy storage tower are hoisted, and drive the power generation equipment to operate in the falling process, so that power generation is completed; and the time needed for construction is short, the power supply efficiency is improved, and the requirement for increasing the power supply amount in a short time is met. The energy storage power generation tower is simple in structure, not limited by terrains, short in construction period and capable of meeting the requirement for urgently increasing the power supply amount in a short time.

Description

Technical field[0001]The present invention relates to the field of power generation technologies, and more particularly to energy storage power generation methods based on gravity potential energy and energy storage power tower.Background technique[0002]The power storage system is stored in a storage electrical energy through a certain medium, and the stored energy is released when needed. Among them, a large-scale power storage system is a key technique for solving intermittent and volatility of renewable energy, and is also key technologies for distributed systems to achieve load balance. The currently large-scale storage technology includes pumping energy storage, compressed air energy storage, and battery energy storage.[0003]For existing implementations, pumping energy is currently the most common large-scale storage electrical energy technology. However, its energy density is relatively low, and the topographic needles needed to build large reservoirs will bring ecological and...

Problems solved by technology

However, its energy density is relatively low and the topography required to build large reservoirs poses ecological and immigration problems

In addition, the construction period of the pumped storage power station is very long (generally about 7 to 15 years), and the construction period is long, which cannot meet the urgent need to increase the power supply in the short term in some areas
