A variety of natural energy supports efficiency-enhancing universal power grid peak-shaving Pinggu energy-storage power station

Abstract

The invention relates to a universal power grid summit-eliminating valley-flattening storage power station beneficiated by various natural energies, provided for solving the problem that the prior art is easily limited by the territory condition. The storage power station comprises one or more than one compressed air storing tank with a heat insulation layer and a photovoltaic power generation device, a gas outlet pipe of each compressed air storing tank is connected with a gas driven generator by a check valve and a heating device, and a gas inlet pipe of each compressed air storing tank is connected with an air compressor by a cooling device; the surplus electricity of the power grid drives the air compressor to store the compressed air, and when the power grid is insufficient in power supply, the stored compressed air drives a generator to supply the power to the power grid; and the photovoltaic power generation device drives a steam compressed air conditioner, a heat absorbing end of the air conditioner absorbs heat from the cooling device, and a cooling end of the air conditioner supplies heat to the heating device. The storage power station is low in investment cost, low in operation cost, high in output benefit, long in service life, is not limited by the territory condition, particularly used for adjusting the electric power storage power grid in one day or in a short time, reliable in performance, high in power supply guaranteeing capability, outstanding in economic, social and environmental benefits, very suitable for popularization and use in all regions.

Description

Technical field [0001] The invention relates to an energy storage power station that adjusts the power grid, in particular to a universal power grid peak-reducing Pinggu energy storage power station supported by a variety of natural energy to support efficiency. Background technique [0002] Large-scale power stations can only obtain satisfactory efficiency due to the large-scale units. However, power plants equipped with huge units are restricted by various conditions and cannot be attached to users. Therefore, they have to concentrate power generation from the grid to users. However, the flexibility of generating units is too large to meet the needs of households. The power grid changes with users' power load sometimes as peaks and sometimes as troughs. At present, the main methods to solve the problem of power shortage during peak power consumption and power waste during low power consumption are: 1. Standby units, because it is not convenient to switch on and off frequently, ...

AI Technical Summary

Problems solved by technology

[0002] Large-scale power plants can only obtain satisfactory efficiency because the scale of the units is large enough, but power plants equipped with giant units cannot be attached to users due to various conditions, so they have to centralize power generation and transmit it to users through the grid

However, the flexibility of power generation cannot meet the needs of households when the unit is too large. The power grid sometimes presents a peak and sometimes a trough with the change of the user's power load.

At present, the main means to solve the problem of power shortage during peak power consumption and power waste during low power consumption are: 1. Standby units, because it is not convenient to switch on and off frequently, this method is only suitable for long-term adjustments, such as peak power consumption in summer 2. Construction of pumped storage power stations. Although this method is convenient for time control, it occupies a lot of land and is limited by water sources and topography. The investment is large and the savings and storage efficiency is low. Difficult to popularize and apply; 3. It has been reported that hydrogen and oxygen are produced by electrolyzing water with surplus electricity in the valley of the power grid, and stored. Power grid, this way, because the fuel cell technology is still immature, expensive, short life, can not guarantee economic benefits, at present, there is no feasibility of popularization and application

[0003] In many rural areas, due to the limited power transmission and distribution conditions, there are often problems with sufficient power during the day and severe shortage of power during peak power consumption at night, and even the use of household appliances.

In the hot summer weather, due to the sharp increase in power consumption of air conditioners and the phenomenon of power cuts everywhere, many factories have to stop production and wait for power, or use expensive diesel self-provided units to generate electricity, which seriously affects industrial and agricultural production and social life. cause many unnecessary losses

In today's society with advanced science, perfect technology, and sufficient manpower and material resources, people are still suffering from limited electricity due to the lack of advanced and practical power grid regulation and storage technology, and the surplus of precious electricity is still lost in vain. The fundamental reason is the lack of technological innovation. , fundamentally: no innovation, no future
