Description

Technical Field

[0001] The present invention relates to the field of zero-carbon building technology, and in particular to a method for determining the installation capacity of a zero-carbon building energy control system based on artificial intelligence. Background Art

[0002] A zero-carbon building is a building that uses renewable energy and has an annual production capacity greater than or equal to the building's total annual energy consumption, and uses no primary energy at all. It can operate independently of the power grid and can rely on renewable energy such as solar or wind power.

[0003] It's worth noting that academic discussion currently focuses on low-carbon buildings, while relatively little research has been conducted on zero-carbon buildings. Currently, there's no clear solution for configuring the energy systems of zero-carbon buildings. Technical questions arise, such as the scale of photovoltaic systems and battery capacity required to meet zero-carbon requirements, and whether other energy sources are needed. These questions are particularly challenging when the data required relies solely on estimates without a clear basis for calculation.

[0004] In addition, there are still deficiencies in the existing research on zero-carbon building energy systems that need to be addressed:

[0005] First, air conditioning energy consumption cannot be effectively managed. Air conditioning is currently the primary energy consumer in buildings, accounting for approximately 70%. Current research primarily utilizes battery storage for energy storage, which is then used in air conditioning systems. This would require a very large battery system. Without effective allocation of air conditioning energy consumption, the efficiency of zero-carbon building energy systems will be very low, resulting in high system costs and difficulty in widespread implementation.

[0006] Second, electric vehicles are not considered in system deployment. The number of electric vehicles will be enormous in the future, and their electricity consumption will be significant. Existing research suggests that electric vehicles will not only be able to charge but also discharge energy to the grid, without affecting their battery life. Therefore, ensuring that electric vehicles charge during peak power generation periods and appropriately discharge energy to the grid during peak power consumption periods can reduce energy system capacity allocation and improve system economics.

[0007] Third, there's insufficient coordination between the subsystems of a zero-carbon building energy system. A zero-carbon building energy system consists of numerous subsystems, such as power generation modules, chemical energy storage modules, physical energy storage modules, and electric vehicle modules. These subsystems must closely collaborate with each other. Failure to consider these interoperability and instead configuring them for maximum capacity will waste energy-saving potential and lead to higher system costs. However, detailed consideration of the logical relationships between modules and the rational allocation of capacity data can improve system economics and enable the widespread adoption of zero-carbon buildings.

[0119] Among them, in the formula (16), the battery constraint condition is the optimal usage range, that is, 60% to 80% of the capacity, then the calculated capacity should be 80% of the installed capacity, that is, the installed capacity is 1.25 times the calculated capacity. b For the calculation of , refer to steps S41 to S44.

[0120] Specifically, if Figure 7 As shown, the step S50 further includes sub-steps S51 to S54. The sub-steps include:

[0121] Step S51: Make the installed capacity P of the physical energy storage module 40 s Meet the air conditioning energy consumption P e2 .

[0122] Step S52: Excluding the use of air-conditioning electrical equipment, the installed capacity P of the physical energy storage module 40 s Deduct the real-time power distribution of the power generation module 20, and consider the distribution coefficient k g2 . Partition coefficient k g1 According to the following formula (17): k g2 =W2 / W0, where W2 is the air conditioning energy consumption and W0 is the total energy consumption for the whole year.

[0123] Step S53: The installation capacity P of the physical energy storage module 40 is sThe service factor is set as k s .

[0124] Since all equipment has a utilization efficiency, energy losses include heat conduction, auxiliary equipment energy consumption, etc. The equipment utilization factor is the coefficient of the installed power minus these losses.

[0125] Step S54: Considering steps S51 to S53, the installation capacity P of the physical energy storage module 40 is set to s Satisfies the following formula (18): P s =(P e2 -k g2 P g ) / k s Among them, P e2 Calculate air conditioning energy consumption for artificial intelligence, k g2 P g is the second distribution coefficient k g2 Multiply by the installed capacity P of the power generation module 20 g , the product is the power directly used by the air conditioning load of the power generation module, k s is the water storage capacity P s The usage factor.

[0126] The above describes the method for determining the installation capacity of a zero-carbon building energy control system based on artificial intelligence of the present invention. The following describes the control system architecture for operating the above method.

[0127] like Figure 8 As shown, the zero-carbon building energy control system of the present invention includes a system controller 10, which electrically controls the power generation module 20, the chemical energy storage module 30, the physical energy storage module 40, the electric vehicle module 50 and the building energy consumption management module 60 through a data bus 11.

[0128] The power generation module 20 includes a power generation module controller 21 connected to the data bus 11 ; the power generation module controller 21 is further connected to a photovoltaic power supply unit 22 and a wind power supply unit 23 .

[0129] The chemical energy storage module 30 includes a chemical energy storage module controller 31 connected to the data bus 11 ; the chemical energy storage module controller 31 is further connected to a battery 32 .

[0130] The physical energy storage module 40 includes a physical energy storage module controller 41 connected to the data bus 11 ; the physical energy storage module controller 41 is further connected to a water energy storage device 42 .

[0131] The electric vehicle module 50 includes an electric vehicle module controller 51 connected to the data bus 11 ; the electric vehicle module controller 51 is further connected to an electric vehicle 52 and a charging station 53 .

[0132] The building energy consumption management module 60 includes an energy consumption management module receiver 61 connected to the data bus 11 , and the energy consumption management module receiver 61 obtains energy consumption data of the zero-carbon building energy system through the data bus 11 .

[0133] like Figure 9 , which shows the workflow of the system controller 10 of the zero-carbon building energy control system of the present invention. The process begins with parameter setting, followed by sequential steps of inputting basic parameters, acquiring historical data, acquiring predicted data, and randomly generating initial PSO particle data for the battery. After generating the initial PSO particle data for the battery, it is determined whether the particles meet the battery constraints. If the constraints are met, iteration begins. If the constraints are not met, the initial values ​​(parameter settings and / or basic parameter input) are adjusted to meet the constraints. After the adjustments are completed, iteration begins.

[0134] Next, the battery fitness value is calculated and the initial PSO particle data for water storage energy is randomly generated. After the initial PSO particle data for water storage energy is generated, it is determined whether the particles meet the water storage energy constraints. When the constraints are met, the iteration begins; when the constraints are not met, the initial values ​​(parameter settings and / or basic parameters) are adjusted to meet the constraints. After the adjustment is completed, the iteration begins.

[0135] Next, the water storage energy adaptability value is calculated and the initial PSO particle data of the electric vehicle is randomly generated. After the initial PSO particle data of the electric vehicle is generated, it is determined whether the particles meet the electric vehicle constraints. If the constraints are met, the iteration begins. If the constraints are not met, the initial values ​​(parameter settings and / or basic parameters) are adjusted to meet the constraints. After the adjustment is completed, the iteration begins.

[0136] Next, the electric vehicle fitness value is calculated, the next iteration begins, and whether the number of iterations has been reached is determined. If the number of iterations has not been reached, the system controller 10 returns to the step of randomly generating the initial PSO particle data for the battery. If the number of iterations has been reached, the system controller 10 ends its operation.

[0137] PSO, or particle swarm optimization, is a population-based stochastic optimization technique. It mimics the swarming behavior of insects, herds of animals, flocks of birds, and schools of fish. These groups collaborate to find food, with each member continuously adapting its search pattern by learning from its own experience and that of other members.

[0138] In an embodiment of the present invention, the water storage device 42 of the physical energy storage module 40 is used as an energy storage device for the air conditioning system. Specifically, the water storage device 42 is used to store the cooling energy of the air conditioning system during off-peak hours (when electricity rates are low), and to release the stored energy during peak hours (when electricity rates are high) for air conditioning. This improves the problem of high energy consumption in the air conditioning system. The method of using batteries to store energy and then convert it into the cooling and heating energy required for air conditioning results in a large battery installation and poor economic efficiency. It also avoids the risk of excessive battery installation, which increases the risk of battery equipment failure and fire safety issues. Furthermore, using batteries to provide energy for the air conditioning system requires three energy conversions: electrical energy to chemical energy to electrical energy to thermal energy. However, using the water storage device 42 as the energy storage device for the air conditioning system requires only one conversion: electrical energy to thermal energy. Therefore, the energy conversion efficiency of the water storage device is higher.

[0139] In an embodiment of the present invention, the electric vehicle module 50 is used to increase the accuracy and flexibility of the present invention's artificial intelligence-based zero-carbon building energy control system. Since the number of electric vehicles will be enormous in the future, their electricity consumption will be significant. Furthermore, according to existing research, electric vehicles will not only be able to charge but also discharge electricity to the grid, without affecting their battery life. Therefore, the present invention's zero-carbon building energy control system utilizes the electric vehicle module 50 to take advantage of the different energy consumption characteristics of electric vehicles 52 compared to other energy-consuming devices. This allows for more accurate configuration of devices such as the photovoltaic power supply unit 22, wind power supply unit 23, and battery 32 of the chemical energy storage module 30 in the power generation module 20, based on the individual consideration of the characteristics of the electric vehicle. Furthermore, when building energy consumption is high, the electric vehicle module controller 51 can be used to control the electric vehicle 52 and / or charging station 53 to discharge electricity, thereby replenishing their electrical energy into the zero-carbon building energy control system, thereby improving the system's flexibility.

[0140] Since the zero-carbon building energy system is composed of numerous modules, including power generation modules, chemical energy storage modules, physical energy storage modules, and electric vehicle modules, each module has completely different operating logic. Without finding the mathematical model and constraints of each module, as well as the constraint relationships between modules, it is impossible to form a mature and practically applicable system design. Therefore, in an embodiment of the present invention, the zero-carbon building energy control system of the present invention is based on the aforementioned system architecture and proposes a mathematical model for allocating energy data based on the logical relationships between modules. The mathematical model has high accuracy and reliability, and is a practical method for determining the installation capacity of the zero-carbon building energy control system that can be applied in specific projects.

[0141] Since different buildings have different annual energy consumption curves due to their architectural properties and the meteorological data of their locations, and the annual energy consumption data also changes due to changes in national holidays. Therefore, in the embodiment of the present invention, it is proposed to use an artificial intelligence algorithm, and the annual energy consumption data (annual energy consumption curve) obtained through repeated training has high reliability. Through the application of this algorithm in different projects, it has a self-learning function, thereby making the application accuracy in zero-carbon building energy systems increasingly higher. Specifically, the principle of the artificial intelligence algorithm adopted by the present invention is that under the guidance of a certain algorithm, the system automatically searches for the optimal result; the purpose of this algorithm is also to guide the system to automatically search for the optimal result that adapts to the retrieval of energy consumption data.

[0142] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
