In the 'electric power energy storage system construction and operation specification' DB11/T1893-2021, although the requirement of the distance from a house to a lithium ion/sodium ion battery with rated energy less than 100KWH is not made, the potential safety hazard still exists in a storage room. The existence of the parking spaces on the same layer creates a non-living space separated from living units for the storage of new energy automobiles, charging piles and household storage batteries, and is assisted by fire-fighting facilities, so that potential safety hazards are reduced and eliminated.

The charging and discharging energy storage device in the step 1) comprises a charging pile, a new energy automobile and a storage battery.

The charging and discharging energy storage equipment in the step 1) is arranged on the free face (namely the pressure relief face) of the parking space on the same floor, and fire fighting facilities are correspondingly arranged. The existence of parking spaces on the same layer provides unique possibility for storing new energy automobiles, and arranging discarded new energy automobile batteries or household storage batteries which are qualified through inspection. The discarded qualified batteries of the new energy automobile or the household storage battery after inspection is placed on the free face (pressure relief face) of the parking space on the same floor, and meanwhile, the fire-fighting facilities are installed, so that potential safety hazards which possibly exist in the discarded qualified batteries of the charging pile, the new energy automobile and the new energy automobile or the household storage battery after inspection are eliminated.

The virtual power plant communication transmission network in the step 2) is a computer network, is connected with the municipal power grid dispatching and business ports, and synchronously transmits the collected valley electricity quantity and the output participating in peak shaving to the valley electricity quantity of the municipal power grid (the existing equipment can be combined into the network).

The main base station system in the step 3) comprises a communication transmission network, a local monitoring system, an operation and maintenance platform and a bidirectional intelligent electric meter, wherein the communication transmission network is arranged by taking a cell as a unit, an area as a unit or an area as a unit;

Some of the terms to which the invention relates are explained below:

the valley electricity refers to electricity wasted by the power grid from 11 nights to 6 early morning hours. Charging piles and storage batteries are arranged on parking spaces on the same floor of the civil building. The charging pile receives the valley electricity to form a user side, the user side charges the new energy automobile and the household storage battery, and the storage battery or the new energy automobile supplies power to the household of the user. The user side collects 'valley' electricity wasted at night to form a distributed micro-grid, the storage battery provides power supply service for household electrical equipment, and abundant electricity of the storage battery is reversely supplied to the municipal power grid.

The term "storage" refers to energy storage equipment in a building, which is stored in a non-residential space of a civil building, such as a new energy vehicle (a movable storage battery) in a parking space on the same floor, a storage battery (a waste and old storage battery eliminated by the new energy vehicle and qualified through inspection can be selected), the user-side charging pile with the bidirectional charging and discharging function can be used for specially collecting and storing night valley electricity wasted by a municipal power grid, and the new energy vehicle and the storage battery can be used as distributed mobile and distributed fixed energy storage of the building.

In 15 months 7 and 2021, the national institute of energy and reform, issued guidance on accelerating the development of new energy storage (issue and reform energy regulation [ 2021 ] No. 1051), encouraged to utilize distributed energy storage facilities such as uninterruptible power supplies, electric vehicles, and user-side energy storage together, and actively supported the diversified development of user-side energy storage.

And in combination with the file requirements, energy storage equipment (such as new energy vehicles and household storage batteries) is installed in parking spaces on the same layer to form a distributed microgrid, so that an achievable technical path is provided for energy storage on the user side.

So-called "direct", i.e. direct current technology. The direct current power supply system is adopted in the residential building, and aims to realize the characteristics of simple direct current, safety and easiness in control, so that distributed power supplies such as valley electricity and energy storage are flexibly and efficiently accessed and regulated, and municipal power grids are collected, applied and reversely supplied in large-scale residential buildings which waste energy. Meanwhile, the characteristic of direct current safety is utilized to create an intrinsically safe electricity utilization environment. The important characteristic of the residential building receiving the valley electricity direct current is the cooperation of the valley electricity, the energy storage, the direct current and the flexibility.

So-called "soft", i.e. flexible power supply technology. The civil building power equipment has the capability of being interruptible (the interruptible means that power supply is stopped from 1 night to 6 early morning hours, and the rest of the time is stopped), and adjustable (when the municipal power grid power consumption peak is reached, the abundant electricity of the power storage equipment supplies power to the municipal power grid), so that the building power demand is changed from rigidity to flexibility. The traditional building energy supply mainly solves the relationship between power supply and building energy consumption, and the flexibility mainly solves the cooperative relationship between mains supply, valley electricity receiving of a distributed micro-grid, energy storage and flexible energy consumption of a civil building. The final purpose of 'soft' in 'Gu Chuzhi soft' is to convert civil building electricity from rigid load to flexible load, and the 'valley Chu Zhirou' is the optimal solution for the cost of realizing the final aim of 'soft'.

The essence of the 'valley Chu Zhirou' power supply mode for peak clipping, valley filling and valley receiving of the same-layer parking space of the civil building is the optimal solution of the cost under the 'double-carbon' target.

The conversion in an electrical manner is one of cost reduction and efficiency enhancement methods under the "dual carbon" goal.

At present, how to realize emission reduction in the operation process of civil buildings, particularly residential buildings, is a worldwide problem to be solved urgently by experts and people in the fields of energy, electric power and engineering. The existing residential building area in China is as follows: 282 billion square meters (Jiang Yi courtyard), the residential building consumes 200 billion degrees of electricity every day (Ouyang Ming courtyard), and in view of continuous thermal power generation, nearly 70 billion degrees of electricity are wasted every 200 billion degrees of electricity every day at night, and the electricity is converted into 86 kilotons of standard coal. 90% of Chinese electric power comes from thermal power and hydropower, wherein the thermal power accounts for 72%, the hydropower accounts for 18%, and future clean energy gradually replaces the thermal power. The difficulty is great.

For civil buildings in China, the carbon peak reaching and carbon neutralization of residential buildings are mainly discussed, the ultimate goal is zero carbon of the residential buildings, and the implementation means is mainly electrification of building energy.

How to realize electrification of building energy, the current main mode is as follows: through energy utilization structure adjustment, direct emission reduction and energy conservation in the operation process of the residential building are realized, and the energy utilization of the residential building is electrified;

through the change of photovoltaic and power utilization modes, the change of the power utilization mode is provided, which means that valley electricity resources are collected, and a power-assisted power system is zero-carbonized;

by changing and optimizing the structure function of the residential building, the use of building materials in the new construction and old modification processes is reduced, so that the carbon emission is reduced, and the emission reduction in the construction process is realized (the carbon emission is reduced by constructing parking spaces on the same floor and canceling underground parking lots).

The power supply mode of 'valley Chu Zhirou' for receiving valley electricity by peak clipping, valley filling and valley filling of parking spaces on the same floor of a civil building is mainly discussed.

It is known that power generation in thermal power plants is continuous for 24 hours. At present, the electricity generated by heat-engine plants in China from 11 o 'clock at midnight to 6 o' clock at morning is dead, so that the electricity is wasted, a large amount of carbon dioxide is discharged, and a large amount of coal resources are consumed. How to store and reasonably utilize the wasted power resources is a worldwide problem.

With the advent of the technology of parking spaces on the same floor of residential buildings and the introduction of the policy of 'one parking space and one charging pile or charging interface' of the fourteen committees of the state, the parking spaces on the same floor of civil buildings are operated by receiving the power supply mode of 'Gu Chuzhi flexible' valley power.

The valley electricity is used, the electricity is wasted by a power grid at night, the collection cost is low, the voltage and the current are stable, and the novel energy automobile and the household storage battery are stable, safe and reliable to use.

The discarded and qualified waste batteries eliminated by the new energy automobile are utilized, the thinking of 'power batteries and echelon utilization' is met, the discarded and qualified waste batteries eliminated by the new energy automobile are paid when purchasing vehicles, the cost is almost zero, the use cost of civil buildings is reduced, and the principle of 'recycling waste materials' building a 'conservation-minded society' is met.

In order to realize the aim of 'double carbon' and realize the living environment of low-carbon life, according to the invention patent of 'high-rise residence and construction method' patent number (ZL 202010471973.9) and the utility model 'high-rise residence community' patent number (ZL202020100353. X), the appearance design patent of 'elevator type floor parking space' applies for patent number (202130101986.2), according to the content in the aforementioned invention patent: the requirement of "setting up the interface that charges of filling electric pile jointly or separately to every floor parking stall or underground parking stall" is established. The invention provides a peak clipping and valley filling type power supply mode for same-layer parking of a civil building.

The proposal of the problems is as follows: with the rapid development of new energy automobiles (electric vehicles), the energy storage battery industry of the new energy automobiles is greatly developed, and the endurance mileage exceeds 400 ㎞. Charging piles are constructed in residential districts which are built and newly built according to the requirements of the national institute of development and improvement and the department of housing construction. For a residential district with one parking space, it is known that a charging pile charges a new energy vehicle once, if the residential district runs in a city, the average running distance is 40 ㎞, about 10 days are needed for charging the new energy vehicle once, and the use efficiency of the charging pile is extremely low.

Because fill electric pile's use, must increase external power supply cable's sectional area increase or add the special cable alone for filling electric pile, increase power supply platform's capacity, intangible increase engineering construction cost and because increase material and equipment and the carbon emission of extra production, simultaneously, increase city electric wire netting's pressure, even need the dilatation.

In order to reduce engineering cost, reduce carbon emission generated by use of materials and equipment and improve the use efficiency of the charging pile, the use efficiency of the charging pile is enabled to reach or approach 100%, valley electricity is fully utilized, a charging system charges a new energy automobile in the valley of power supply of the new energy automobile, and the new energy automobile charges a living unit (user) in the peak of electricity utilization. The method has the advantages that the method follows the concept of low energy consumption, peak clipping, valley filling and complementary guarantee, the alternating current is converted into the direct current, the engineering cost is reduced, the use efficiency is improved, the civil building receives the valley electricity through the charging pile, the civil building becomes a power storage station, the external grid power resource is received, the electricity is stored in the civil, the toughness of the city is enhanced, and the safety of the city is improved.

Aiming at the civil buildings and residential districts, the charging pile and the distributed energy storage equipment are fully utilized, the valley electricity is received, an intelligent system and a micro-grid system (virtual grid) are constructed, the use cost of users and the emission of carbon dioxide in the operation and use management of the residential building districts are reduced, and the living principle of low carbon and environmental protection is practiced. Meanwhile, the civil building is changed into a power storage station, the power storage station receives external network power resources, stores the power in the people, increases the toughness of the city, and improves the safety of the city.

In addition, the civil building receiving the valley electricity 'Gu Chuzhi soft' in the parking spaces on the same floor is a 'virtual power plant' for urban energy storage and peak shaving in the future. The parking spaces on the same floor of the civil building receive the power plant-electricity dispatching place of the virtual power plant under the power supply mode of 'Gu Chuzhi soft'.

Virtual power plants-virtually nonexistent, virtual "sites for electricity dispatch", are a form of the internet. In the technology of 'valley Chu Zhi soft', a virtual power plant is one of important technical means for realizing an intelligent power distribution network, and a power supply, charging pile equipment, valley electricity loads, household energy storage equipment, a new energy automobile, household electrical equipment facilities and the like of each user unit dispersed in a civil building with parking spaces on the same floor are integrated through an advanced information communication technology and a software system and combined into a special power plant to participate in power grid operation.

The Gu Chuzhi flexible virtual power plant system can be used as a 'positive power plant' to supply power to a municipal power grid during peak power utilization, can also be used as a 'negative power plant' to absorb valley power to be supplied to a user unit, consumes the electricity wasted by the municipal power system at night, can flexibly cut peaks and fill valleys, breaks through the physical boundary between the power generation side and the power utilization side in the traditional power system, and realizes arbitrage.

The electricity dispatching means that the generated energy, the power supply quantity and the power consumption quantity are matched through an algorithm, data, a system and the like to form supply and demand balance and production and use balance.

The purpose is not to waste electricity and resources, the utilization of the maximum efficiency of power resources is realized, carbon neutralization is realized, energy is protected, and the human environment is protected.

The following examples illustrate the situation where civil buildings waste electricity and resources:

the daily average power consumption of residential buildings in China is 200 hundred million degrees (Ouyang Ming academy of sciences), and in view of continuous thermal power generation, 200 hundred million degrees of electricity per day wastes nearly 70 hundred million degrees of electricity (kwh) at night, and the electricity is converted into 86 million tons of standard coal (1 ton of standard coal equals 8141 degrees of electricity). The standard coal wasted in 365 days a year can reach: 5363 and 31390 ten thousand tons, the coal purchase price of the power enterprise is not more than 640 yuan/ton in 12 months and 14 days in 2020 by national development and improvement commission, and the coal value wasted each year: 2000 billion yuan.

The night valley electricity wasted by residential buildings in China each year is equivalent to 24.6 three gorges annual energy production (the cumulative energy production of the three gorges power station in 2021 is 1036.49 hundred million kwh).

If, newly-built 10 hundred million square meters per square meter per household, every 100 square meters high-rise residence, every household storage 50 degrees millet electricity (50 kwh), reform transform in the city renewal and install elevator formula floor parking stall 10 hundred million square meters, one terraced two households, every 100 square meters, every household storage 50 degrees electricity (50 kwh), supply new energy automobile and domestic power consumption, when the electric quantity is rich, the electricity is sold to municipal power grids in the reverse direction, both can save extravagant night millet electricity every day: 10 hundred million degrees (10 hundred million kwh, equivalent to 3.66 three gorges power station daily generated energy), can also reverse the power selling, and the peak valley price difference is got to the cover, increases user's income. If 70% of the daily stored electricity is used for arbitrage, the peak-to-valley electricity difference is calculated according to 0.7 yuan/degree (published by 8-month national network in 2022), arbitrage can be performed by 10 million degrees x 70% x 0.7 yuan/degree =4.9 yuan per day, annual average arbitrage is 4.9 yuan/day x 365 day =1789.5 yuan, and emission of carbon dioxide is reduced by 33 ten thousand tons per year.

The Gu Chuzhi flexible virtual power plant can timely calculate the power storage capacity of Gu Chuzhi flexible civil buildings, the supply quantity and the demand quantity of reverse power supply, timely meet corresponding requirements, adjust power, cut peaks and fill valleys, and enhance the toughness and the safety of cities.

Therefore, the 'Gu Chuzhi flexible' virtual power plant is a management center of urban electric power wealth and can also be called an energy cloud. Meanwhile, the device also has a transaction function, and the transaction of the power and carbon emission assets is realized.

Under the policy, the virtual power plant which is produced by the way that the parking spaces on the same floor of the civil building receive valley electricity in a Gu Chuzhi flexible power supply mode can be opened to the profit era.

The fourteen-five modern energy system plan of China is clearly proposed, and the construction of the response capability of the power demand side is enhanced, and the scattered demand response resources are integrated. The virtual power plant which is produced by the way that the parking spaces on the same floor of the civil building receive valley electricity 'Gu Chuzhi soft' power supply is a powerful hand grip for achieving the purpose.

The virtual power plant corresponding to the Gu Chuzhi flexibility can effectively and reasonably and effectively configure the wasted power energy in a marketized manner, so that the power resource utilization efficiency is remarkably improved, the user side can store the red profit of the energy storage at the valley power level, the reverse power supply can be realized through the peak-valley power difference, meanwhile, due to the effective storage of the user side electric energy, the civil building is changed into an energy storage power station, the resistance to various natural disasters is facilitated, when the city is powered off, the self circulation is carried out by utilizing the self distributed micro-grid of the civil building, the toughness of the city is improved, and the safety of the city is enhanced. The social significance and the economic benefit are very great.

The virtual power plant corresponding to Gu Chuzhi soft can be used as an independent market subject to participate in electric power market trading.

Due to the fact that a large number of obsolete batteries of new energy automobiles are increased (the quantity of obsolete power batteries exceeds 20 ten thousand tons in China in 2020, and the quantity of obsolete power batteries exceeds 78 ten thousand tons in 2025), the distributed energy storage scale of the power supply mode of 'Gu Chuzhi soft' for the parking spaces on the same floor of a civil building is greatly increased, and the problem that resources can be accommodated in a virtual power plant corresponding to 'Gu Chuzhi soft' is solved; the national green electricity trading method solves the rule problem of marketization operation of a virtual power plant: the progressive forming of the profit mode solves the problem of sustainable development of the virtual power plant. Nowadays, the establishment of the main status of the independent market of the virtual power plant has the identity of legal market entry. As a core structure of the smart grid, a virtual power plant corresponding to 'Gu Chuzhi soft' is realized from 1 to N, a new racetrack is added for the virtual power plant, and a new blue sea is formed.

How to realize the operation of a 'valley Chu Zhirou' virtual power plant for receiving valley electricity at a parking place on the same floor of a civil building adopts the following steps:

the user-side distributed micro-grid digital intelligent electric meter is connected with a corresponding virtual power plant data center, and the supply quantity of received valley electricity is read every day;

the digital center of the virtual power plant is connected with the municipal power grid electric power transaction platform, the virtual power plant can timely calculate the supply and demand of the 'valley electricity' demand, the 'peak electricity' supply and the reverse power supply of the digital intelligent ammeter of the user side distributed micro-grid of the civil building 'Gu Chuzhi soft', the corresponding demand is timely met, the electric power is timely adjusted, the peak clipping and the valley filling are realized, and the peak valley electricity difference is realized.

The 'valley Chu Zhirou' virtual power plant for receiving valley electricity in the same-layer parking space of the civil building is equivalent to a trading platform, and user-side distributed micro-grid peak-valley electricity difference trading fees are earned.

The method comprises the steps of selecting a standard (obsolete waste batteries qualified through inspection of the new energy vehicle), a detection means and an inspection standard for the storage battery.

After the new energy automobile power battery is retired, 70-80% of residual electric quantity still exists generally, and the new energy automobile power battery can be used in a household energy storage scene, so that the maximum utilization of the residual energy is realized. At present, the technologies such as echelon utilization and detection are mature, the technologies such as battery residual value assessment and remote monitoring and early warning are optimized and improved continuously, and echelon products are applied to the fields such as energy storage and standby power.

According to the new energy automobile power storage battery echelon utilization management method, the Ministry of industry and communications (2021) 114, reasonable echelon utilization enterprises are selected to provide qualified new energy automobile retired power batteries for a civil building same-floor parking space Gu Chuzhi flexible power supply mode.
