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 power generation flexibility of the unit is too large to meet the needs of users. 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

Abstract

The invention relates to a terminal power grid regulation and storage station built by using an unused building. By the terminal power grid regulation and storage station, power regulation and power storage of the terminal power grid can be carried out. The terminal power grid regulation and storage station comprises a multi-storey building, wherein an induced draft fan or a natural induced draft tower barrel is arranged on each corridor end window; an air inlet window with blinds is arranged on each outer window; an air guiding duct is arranged between each inner window and the corresponding corridor end window; a plurality of parallel capacitor power storage units are arranged in rooms on the front side and the rear side of each corridor and are connected with a power-supply network via power grid connection and output devices; temperature sensors are arranged in the rooms on the front side and the rear side of each corridor or on the capacitor power storage units, and control the opening degree of the air inlet windows with the blinds or control the opening degree of the air inlet windows with the blinds and the exhaust air rate of the induced draft fans through ventilation controllers. The terminal power grid regulation and storage station has the advantages that the original building is not required to be rebuilt, and can be used by directly arranging corresponding equipment, the construction period is short, the investment cost and the running cost are low, the output effect is high, the station can be constructed flexibly according to conditions, and is suitable for regulating and storing the power of a terminal power grid in one day or in a short time, and the power supply guarantee capability is high.
