Description

Background Art

[0002] The building microgrid cluster control system is a microgrid control system that generates new energy to supply and regulate the electrical loads in buildings. It can achieve self - sufficiency in power supply for the electrical loads in buildings through the energy supply module. However, when the power demand of the electrical loads increases, or when the energy production of the energy supply module decreases due to external reasons, the power supply to the electrical loads may be lower than the power consumption. Therefore, in such cases, it is necessary to connect the electrical loads to the external power supply terminal to maintain the electrical safety of the electrical loads.

[0003] However, due to the inconsistent power demands of the electrical loads in the current building microgrid control system, and the dissimilar power consumption times and power consumption powers, there will be a phenomenon of mismatch between the electrical loads and the energy supply module, resulting in large voltage fluctuations of the electrical loads. If the electrical load is a scientific instrument with high precision or a device with high requirements for power stability, such a phenomenon may cause losses to users. Therefore, it is necessary to re - distribute the electrical loads and the energy supply module. Summary of the Invention

[0007] In an exemplary embodiment of the present application, step S300 includes: Step S310: Traverse the energy consumption ratio and the energy consumption ratio threshold corresponding to the m-th building electrical load in each historical time period. If F mi >Y mi , then determine the i-th historical time period as the target historical time period corresponding to the m-th building electrical load; Step S320: If the ratio of the number of target historical time periods corresponding to the m-th building electrical load to j is less than the preset time period number ratio threshold, then determine the m-th building electrical load as the building load to be adjusted.

[0008] In an exemplary embodiment of the present application, step S400 includes: Step S410: Determine the energy supply module corresponding to each building load to be adjusted as the energy supply module to be adjusted; Step S420: Determine any one of the building loads to be adjusted as the first building load, and determine the other building loads to be adjusted except the first building load as the second building load; Step S430: According to the total energy consumption corresponding to the first building load in each historical time period, and the module energy production corresponding to each energy supply module to be adjusted in each historical time period, determine the target energy supply module corresponding to the first building load from several energy supply modules to be adjusted; Step S440: Determine the first building load as the target building load; Step S450: Select any one of several second building loads as the first building load, and return to step S430.

[0009] In an exemplary embodiment of the present application, step S430 includes: Step S431: Obtain the total energy consumption corresponding to the first building load in each historical time period to obtain the second total energy consumption list G=(G1, G2,..., G i ,..., G j ); where G i is the total energy consumption corresponding to the first building load in the i-th historical time period; Step S432: Obtain the module energy production corresponding to each energy supply module to be adjusted in each historical time period, so as to obtain a module production energy list set H = (H1, H2,..., H p ,..., H q ); where p = 1, 2,..., q; q is the number of energy supply modules to be adjusted; H p is the module production energy list corresponding to the p-th energy supply module to be adjusted; H p =(H p1 , H p2 ,..., H pi ,..., H pj ); H pi is the module energy production corresponding to the p-th energy supply module to be adjusted in the i-th historical time period; The module energy production is the energy produced by the energy supply module in the historical time period; Step S433: According to the second total energy consumption list G and the module production energy list H p corresponding to the p-th energy supply module to be adjusted, determine the production-to-consumption energy ratio M i = H pi / G i ; Step S434: Traverse the production-to-consumption energy ratios corresponding to the first building load and the p-th energy supply module to be adjusted in each historical time period. If M i is greater than the energy consumption ratio threshold of the building load to be adjusted corresponding to the p-th energy supply module to be adjusted in the i-th historical time period, then determine the i-th historical time period as the first historical time period corresponding to the first building load; Step S435: If the ratio of the number of the first historical time periods corresponding to the first building load to j is greater than or equal to the preset time period number ratio threshold, then determine the energy supply module with the largest number of the first historical time periods corresponding to the first building load as the target energy supply module corresponding to the first building load.

[0010] In an exemplary embodiment of the present application, step S434 further includes: Step S4341: If M i is greater than the energy consumption ratio threshold of the building load to be adjusted corresponding to the p-th energy supply module to be adjusted in the i-th historical time period and less than the preset maximum energy consumption ratio threshold, then determine the i-th historical time period as the first historical time period corresponding to the first building load.

[0011] In an exemplary embodiment of the present application, step S435 further includes: Step S4351: If the ratio of the number of the first historical time periods corresponding to the first building load to j is less than a preset time period number ratio threshold, then determine the first building load as the third building load, and execute Step S450.

[0012] In an exemplary embodiment of the present application, Step S500 includes: Step S510: Disconnect the power supply connection between each energy supply module to be adjusted and the corresponding building load to be adjusted; Step S520: Establish a power supply connection between each target energy supply module and the target building load corresponding to the target energy supply module.

[0013] In an exemplary embodiment of the present application, after Step S500, the multi - energy input building micro - grid cluster control system is further configured to execute the following steps: Step S610: Determine the energy supply modules to be adjusted that are not the target energy supply modules among several energy supply modules to be adjusted as the first energy supply modules; Step S620: According to the power consumption of several third building loads and a preset energy matching rule, allocate several first energy supply modules to several third building loads.

[0014] The present invention has at least the following beneficial effects: The multi - energy input building micro - grid cluster control system of the present invention first determines the energy consumption ratio threshold corresponding to each electricity - consuming building load in each historical time period according to the effective production time period and the affected production time period of the energy supply module corresponding to each electricity - consuming building load in a number of historical time periods. Then, according to the module energy consumption and the total energy consumption of each electricity - consuming building load in each historical time period, it determines the energy consumption ratio corresponding to each electricity - consuming building load in each historical time period. Next, according to the energy consumption ratio and the energy consumption ratio threshold corresponding to each electricity - consuming building load, it determines the building load to be adjusted from a number of electricity - consuming building loads. And according to the total energy consumption corresponding to any building load to be adjusted in each historical time period, as well as the module production energy and the energy consumption ratio threshold corresponding to other building loads to be adjusted in each historical time period, it determines the target energy supply module corresponding to the building load to be adjusted from a number of energy supply modules corresponding to other building loads to be adjusted. Finally, it disconnects the power supply connection of the target energy supply module corresponding to each building load to be adjusted and constructs a power supply connection with the building load to be adjusted. The energy consumption ratio threshold is determined according to the effective production time period and the affected production time period of the energy supply module corresponding to each electricity - consuming building load in a number of historical time periods, which can make the determined energy consumption ratio threshold adaptively adjust according to different historical time periods of different electricity - consuming building loads, improve the flexibility of threshold comparison, and make the determination of the building load to be adjusted more accurate. Moreover, by adjusting the power supply end of the building load to be adjusted, the production energy of the target energy supply module matched by the building load to be adjusted can meet the electricity demand of the building load to be adjusted, so as to achieve the purpose of energy conservation, emission reduction and full utilization of the energy supply module.

For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0016] Figure 1 It is a flowchart of the method executed by the multi - energy input building micro - grid cluster control system provided by the embodiment of the present invention. Detailed Embodiments

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] A building microgrid cluster control system with multiple energy inputs, the building microgrid cluster control system with multiple energy inputs includes the municipal power grid, a number of energy supply modules and a number of electrical building loads, and each electrical building load is powered by the municipal power grid and an energy supply module; the energy supply module can be a solar module, a wind energy module, etc. that can generate electricity through clean energy; a number of electrical building loads are located in the same geographical area, and can be the load devices of several office buildings in the same park, or the load devices of several residential buildings in the same community; at the initial power supply stage of each electrical building load, it is powered by the municipal power grid and only one energy supply module (the type of energy for power generation), for example, the first electrical building load is powered by the municipal power grid and the solar module, and the second electrical building load is powered by the wind energy module; when the energy production of the energy supply module is less than the energy consumption of the electrical building load, the municipal power grid is used to supply power to the electrical building load, and when the energy production of the energy supply module can meet the energy consumption demand of the electrical building load, the energy supply module is used to supply power to the electrical building load. In addition, the power supply distribution between the electrical building load and the energy supply module is determined by the power supply distribution logic recorded in the prior art.

[0019] Among them, as Figure 1 shown, the building microgrid cluster control system with multiple energy inputs is used to execute the following method: Step S100: According to the energy supply module corresponding to each electrical building load, in the effective production time period and the affected production time period in a number of historical time periods, determine the energy consumption ratio threshold corresponding to each electrical building load in each historical time period; The energy supply module corresponding to the electrical building load is the energy supply module that supplies power to the electrical building load. The effective production time period is the time period preset by the energy supply module in the historical time period during which electrical energy can be produced (for example, the effective production time period of the solar module every day is the time period between local sunrise and sunset), and the affected production time period is the time period during which the energy supply module cannot produce electrical energy due to external factors during the effective production time period (for example, the time period when the solar module has a reduced production capacity or cannot produce electricity due to weather reasons on a certain day). The length of the historical time period can be determined by the user (for example, seven days).

[0020] Further, step S100 includes step S110 - step S130: Step S110: Obtain the effective production time period of the energy supply module that supplies power to each electrical building load in each historical time period, and obtain the effective production time period list set A=(A1, A2,..., A m ,..., A n ); where, m = 1, 2,..., n; n is the number of electrical building loads; A mThe list of effective production time periods corresponding to the energy supply module for powering the m-th building electrical load; A m =(A m1 , A m2 ,..., A mi ,..., A mj ); i = 1, 2,..., j; j is the number of historical time periods; A mi is the effective production time period of the energy supply module for powering the m-th building electrical load in the i-th historical time period; The end time of the i-th historical time period is the start time of the (i + 1)-th historical time period, and the end time of the j-th historical time period is 0:00 on the date of the current time; the length of each historical time period is equal; Step S120, obtain the affected production time periods of the energy supply module for powering each building electrical load in each historical time period, and obtain the list set B of affected production time periods = (B1, B2,..., B m ,..., B n ); where B m is the list of affected production time periods corresponding to the energy supply module for powering the m-th building electrical load; B m =(B m1 , B m2 ,..., B mi ,..., B mj ); B mi is the affected production time period of the energy supply module for powering the m-th building electrical load in the i-th historical time period; Step S130, determine the energy consumption ratio threshold Y mi =(1 - C mi / A mi ) × Y0; where Y0 is the preset initial energy consumption ratio threshold; 0 < Y0 < 1; If B mi ≥ B 0i , then determine C mi = B mi - B 0i ; B 0i is the preset base value of the affected production time period corresponding to the i-th historical time period; If B mi <B 0i , then determine C mi to be zero.

[0021] The energy consumption ratio threshold is determined based on the effective production time periods and affected production time periods of the energy supply modules corresponding to each power-consuming building load in a number of historical time periods. This allows the determined energy consumption ratio threshold to be adaptively adjusted according to different historical time periods of different power-consuming building loads, rather than just a fixed threshold, improving the flexibility of threshold comparison and enabling more accurate determination of the building loads to be adjusted subsequently.

[0022] Step S200: Determine the energy consumption ratio corresponding to each power-consuming building load in each historical time period according to the module energy consumption and total energy consumption of each power-consuming building load in each historical time period. The module energy consumption is the energy produced by the energy supply module consumed by the power-consuming building load during the historical time period, and the total energy consumption is the total energy consumed by the power-consuming building load during the historical time period.

[0023] Furthermore, step S200 includes steps S210 - S230: Step S210: Obtain the module energy consumption of each power-consuming building load in each historical time period to obtain a list set D of module energy consumption = (D1, D2,..., D m ,..., D n ); where D m is the list of module energy consumption corresponding to the mth power-consuming building load; D m =(D m1 , D m2 ,..., D mi ,..., D mj ); D mi is the module energy consumption of the mth power-consuming building load in the ith historical time period; Step S220: Obtain the total energy consumption of each power-consuming building load in each historical time period to obtain a first list set E of total energy consumption = (E1, E2,..., E m ,..., E n ); where E m is the list of total energy consumption corresponding to the mth power-consuming building load; E m =(E m1 , E m2 ,..., E mi ,..., E mj ); E mi is the total energy consumption of the mth power-consuming building load in the ith historical time period; Step S230: Determine the energy consumption ratio F corresponding to the mth power-consuming building load in the ith historical time period according to the list set D of module energy consumption and the first list set E of total energy consumptionmi =D mi / E mi 。

[0024] Step S300: Determine the building load to be adjusted from several building loads according to the energy consumption ratio and the energy consumption ratio threshold corresponding to each building load with electricity consumption. The building load to be adjusted is the building load with electricity consumption for which the power supply of the energy supply module needs to be adjusted, that is, it means that in the current power supply stage, the energy production of the energy supply module cannot meet the energy consumption of the building load with electricity consumption, and the proportion of the power supply from the municipal power grid in the energy consumption of the building load with electricity consumption is too large. Therefore, for the purpose of energy conservation and emission reduction and making full use of the energy supply module, it is necessary to adjust the energy supply module of this building load with electricity consumption.

[0025] Further, step S300 includes steps S310 - S320: Step S310: Traverse the energy consumption ratio and the energy consumption ratio threshold corresponding to the m-th building load with electricity consumption in each historical time period. If F mi > Y mi , then determine the i-th historical time period as the target historical time period corresponding to the m-th building load with electricity consumption. Step S320: If the ratio of the number of target historical time periods corresponding to the m-th building load with electricity consumption to j is less than the preset time period number ratio threshold, then determine the m-th building load with electricity consumption as the building load to be adjusted.

[0026] The time period number ratio threshold is a number greater than 0 and less than 1.

[0027] If the ratio of the number of target historical time periods corresponding to the building load with electricity consumption to j is less than the preset time period number ratio threshold, it means that in most historical time periods of this building load with electricity consumption, the proportion of power supply from the municipal power grid is larger than the proportion of power supply from the energy supply module. Then, it is necessary to adjust the energy supply module of this building load with electricity consumption. Therefore, determine this building load with electricity consumption as the building load to be adjusted.

[0028] Step S400: Determine the target energy supply module corresponding to the building load to be adjusted from several energy supply modules corresponding to other building loads to be adjusted according to the total energy consumption corresponding to the building load to be adjusted in each historical time period, and the module energy production and energy consumption ratio threshold corresponding to other building loads to be adjusted in each historical time period. The module energy production is the energy produced by the energy supply module in the historical time period.

[0029] The target energy supply module is the energy supply module determined after adjusting the energy supply for the building load to be adjusted, and the target energy supply module supplies power to the building load to be adjusted.

[0030] Further, step S400 includes steps S410 - S450: Step S410: Determine the energy supply module corresponding to each building load to be adjusted as the energy supply module to be adjusted; Step S420: Determine any building load to be adjusted as the first building load, and determine the other building loads to be adjusted except the first building load as the second building load; Step S430: Determine the target energy supply module corresponding to the first building load from several energy supply modules to be adjusted according to the total energy consumption corresponding to the first building load in each historical time period and the module energy production corresponding to each energy supply module to be adjusted in each historical time period; Among them, step S430 includes steps S431 - S435: Step S431: Obtain the total energy consumption corresponding to the first building load in each historical time period to obtain the second total energy consumption list G = (G1, G2,..., G i ,..., G j ); where G i is the total energy consumption corresponding to the first building load in the i-th historical time period; Step S432: Obtain the module energy production corresponding to each energy supply module to be adjusted in each historical time period to obtain the module energy production list set H = (H1, H2,..., H p ,..., H q ); where p = 1, 2,..., q; q is the number of energy supply modules to be adjusted; H p is the module energy production list corresponding to the p-th energy supply module to be adjusted; H p =(H p1 , H p2 ,..., H pi ,..., H pj ); H pi is the module energy production corresponding to the p-th energy supply module to be adjusted in the i-th historical time period; Step S433: Determine the production - consumption ratio M p corresponding to the first building load and the p-th energy supply module to be adjusted in the i-th historical time period according to the second total energy consumption list G and the module energy production list H i =H pi / G i ; The energy production - consumption ratio represents the ratio of the module energy production of the energy supply module to be adjusted to the energy consumption of the first building load within the same historical time period. The smaller the energy production - consumption ratio, the smaller the module energy production of the energy supply module to be adjusted compared to the energy consumption of the first building load, and the less able the energy supply module to be adjusted is to meet the electricity demand of the first building load. Conversely, the larger the energy production - consumption ratio, the larger the module energy production of the energy supply module to be adjusted compared to the energy consumption of the first building load, and the more able the energy supply module to be adjusted is to meet the electricity demand of the first building load.

[0031] Step S434: Traverse the energy production - consumption ratios corresponding to the first building load and the p - th energy supply module to be adjusted in each historical time period. If M i is greater than the energy consumption ratio threshold of the building load to be adjusted corresponding to the p - th energy supply module to be adjusted in the i - th historical time period, then determine the i - th historical time period as the first historical time period corresponding to the first building load. If M i is greater than the energy consumption ratio threshold of the building load to be adjusted corresponding to the p - th energy supply module to be adjusted in the i - th historical time period, it means that the p - th energy supply module to be adjusted can meet the electricity demand of the first building load in the i - th historical time period.

[0032] On the other hand, as another embodiment of step S434, step S434 further includes step S4341: Step S4341: If M i is greater than the energy consumption ratio threshold of the building load to be adjusted corresponding to the p - th energy supply module to be adjusted in the i - th historical time period and less than the preset maximum energy consumption ratio threshold, then determine the i - th historical time period as the first historical time period corresponding to the first building load.

[0033] Due to the principle of energy conservation, emission reduction and non - waste of energy, on the premise that the energy supply module to be adjusted meets the electricity demand of the first building load, it is also necessary to limit the energy production of the energy supply module to be adjusted from being excessively greater than the energy consumption of the first building load. Otherwise, if the energy production of the energy supply module to be adjusted is excessive, it will cause energy waste. Therefore, when determining the first historical time period, it is also necessary to make M i less than the preset maximum energy consumption ratio threshold, and the preset maximum energy consumption ratio threshold is greater than the maximum value among several energy consumption ratio thresholds.

[0034] Step S435: If the ratio of the number of the first historical time periods corresponding to the first building load to j is greater than or equal to the preset time period number ratio threshold, then determine the energy supply module to be adjusted with the largest number of the first historical time periods corresponding to the first building load as the target energy supply module corresponding to the first building load, and execute step S440.

[0035] The number of the first historical time periods corresponding to the first building load is the largest among the energy supply modules to be adjusted, which is expressed as the energy supply module to be adjusted with the closest energy production to the energy consumption demand of the first building load. Therefore, it is determined as the target energy supply module corresponding to the first building load.

[0036] On the other hand, step S435 further includes step S4351: Step S4351: If the ratio of the number of the first historical time periods corresponding to the first building load to j is less than the preset time period number ratio threshold, then the first building load is determined as the third building load, and step S450 is executed.

[0037] If the ratio of the number of the first historical time periods corresponding to the first building load to j is less than the preset time period number ratio threshold, it means that the energy production of all the energy supply modules to be adjusted does not meet the energy consumption demand of the first building load. Therefore, the first building load is determined as the third building load for subsequent re-power supply allocation.

[0038] Step S440: Determine the first building load as the target building load; Step S450: Select any one of several second building loads as the first building load, and return to step S430.

[0039] After the target energy supply module is determined for the first building load, the first building load is determined as the target building load; after the target energy supply module is not determined for the first building load, the first building load is determined as the third building load; then, select any one of several second building loads as the new first building load, and execute step S430 - step S450 again until all the second building loads are determined as the first building load, indicating that the power supply adjustment of the target energy supply module has been completed for all the building loads to be adjusted.

[0040] Step S500: Disconnect the power supply connection of the target energy supply module corresponding to each building load to be adjusted, and establish a power supply connection with the building load to be adjusted.

[0041] Furthermore, step S500 includes steps S510 - S520: Step S510: Disconnect the power supply connection between each energy supply module to be adjusted and the corresponding building load to be adjusted; Step S520: Establish a power supply connection between each target energy supply module and the target building load corresponding to the target energy supply module.

[0042] After determining the building load to be adjusted and the energy supply module to be adjusted, disconnect the power supply connection for each building load to be adjusted and each energy supply module to be adjusted, and reconstruct the power supply connection between the target building load for which the target energy supply module has been determined and the target energy supply module, so that the target energy supply module supplies power to the corresponding target building load.

[0043] In addition, after step S500, the building microgrid cluster control system with multi-energy input is further configured to execute steps S610 - S620: Step S610: Determine the non-target energy supply modules among the several energy supply modules to be adjusted as the first energy supply modules; Step S620: According to the power consumption of several third building loads and a preset energy matching rule, allocate several first energy supply modules to several third building loads.

[0044] The third building load is the building load to be adjusted for which the power supply adjustment has not been completed, and the first energy supply module is the remaining energy supply module to be adjusted after determining the target energy supply module.

[0045] Through the preset energy matching rule, the power supply adjustment for several first energy supply modules and several third building loads is performed. The energy matching rule can be a power supply adjustment rule customized by the user or a power supply allocation rule in the prior art. For example, according to the usage area or power consumption of the third building load, the several first energy supply modules are allocated energy (for example, if the several first energy supply modules include two solar modules, three wind energy modules, and four water energy modules, after adjustment through the energy matching rule, one solar module, two wind energy modules, and one water energy module are allocated to a certain third building load for power supply to this third building load).

[0046] The multi - energy input building micro - grid cluster control system of the present invention first determines the energy consumption ratio threshold corresponding to each electricity - consuming building load in each historical time period according to the effective production time period and the affected production time period of the energy supply module corresponding to each electricity - consuming building load in a number of historical time periods. Then, according to the module energy consumption and the total energy consumption of each electricity - consuming building load in each historical time period, it determines the energy consumption ratio corresponding to each electricity - consuming building load in each historical time period. Next, according to the energy consumption ratio and the energy consumption ratio threshold corresponding to each electricity - consuming building load, it determines the building loads to be adjusted from a number of electricity - consuming building loads. And according to the total energy consumption corresponding to any building load to be adjusted in each historical time period, as well as the module production energy and the energy consumption ratio threshold corresponding to other building loads to be adjusted in each historical time period, it determines the target energy supply module corresponding to the building load to be adjusted from a number of energy supply modules corresponding to other building loads to be adjusted. Finally, it disconnects the power supply connection of the target energy supply module corresponding to each building load to be adjusted and establishes a power supply connection with the building load to be adjusted. The energy consumption ratio threshold is determined according to the effective production time period and the affected production time period of the energy supply module corresponding to each electricity - consuming building load in a number of historical time periods, which can make the determined energy consumption ratio threshold adaptively adjusted according to different historical time periods of different electricity - consuming building loads, improving the flexibility of threshold comparison, making the determination of the building loads to be adjusted more accurate. And by adjusting the power supply end of the building load to be adjusted, the production energy of the target energy supply module matched by the building load to be adjusted can meet the electricity demand of the building load to be adjusted, so as to achieve the purpose of energy conservation and emission reduction and the full utilization of the energy supply module.
