Description

Technical Field

[0001] The present invention relates to the field of energy supply, and in particular to a building microgrid cluster control system with multiple energy inputs. Background Art

[0002] The building microgrid cluster control system is a microgrid control system that regulates the power supply to the electrical loads in the building by generating new energy. It can be self-sufficient in electricity consumption for the electrical loads in the building through the energy supply module. However, when the electricity demand of the electrical loads increases, or the output of the energy supply module decreases due to external reasons, the energy supply of the electrical loads may be lower than the energy consumption. Therefore, in this case, the electrical loads need to be connected to the external power supply terminal to maintain the power safety of the electrical loads.

[0003] However, since the power demands of the power loads in the current building microgrid control system are not uniform, and the power consumption time and energy consumption power are also not similar, there will be a mismatch between the power loads and the energy supply module, resulting in large voltage fluctuations in the power loads. If the power loads are high-precision scientific instruments or equipment with high requirements for power stability, this phenomenon may cause losses to users. Therefore, it is necessary to reallocate the power loads and energy supply modules. Summary of the Invention

[0034] In an exemplary embodiment of the present application, step S400 includes:

[0035] Step S410: determining the energy supply module corresponding to each building load to be adjusted as the energy supply module to be adjusted;

[0036] Step S420: Determine any building load to be adjusted as a first building load, and determine other building loads to be adjusted except the first building load as second building loads;

[0037] Step S430: Determine a target energy supply module corresponding to the first building load from among the energy supply modules to be adjusted based on the total energy consumption of the first building load in each historical time period and the module energy production of each energy supply module to be adjusted in each historical time period.

[0039] Step S450: Select any one of the second building loads as the first building load, and return to step S430.

[0040] In an exemplary embodiment of the present application, step S430 includes:

[0041] Step S431: Obtain the total energy consumption corresponding to the first building load in each historical time period to obtain a second total energy consumption list G=(G1, G2, ..., G i ,...,G j ); where G i is the total energy consumption of the first building load in the i-th historical time period;

[0042] Step S432: Obtain the module production capacity corresponding to each energy supply module to be adjusted in each historical time period to obtain the module production capacity 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 The module capacity list corresponding to the p-th energy supply module to be adjusted;

If M i If the energy consumption ratio 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 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, the i-th historical time period is determined as the first historical time period corresponding to the first building load;

[0047] Step S435: If the ratio of the number of 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, the energy supply module to be adjusted with the largest number of first historical time periods corresponding to the first building load is determined as the target energy supply module corresponding to the first building load.

[0054] Step S520 : Establishing a power supply connection between each target energy supply module and the target building load corresponding to the target energy supply module.

BRIEF DESCRIPTION OF THE DRAWINGS

[0060] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for use in the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0061] Figure 1 This is a flow chart of a method executed by a building microgrid cluster control system with multiple energy inputs provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0063] A multi-energy input building microgrid cluster control system, which includes a city grid, several energy supply modules and several power-consuming building loads, each of which is powered by the city grid and an energy supply module; the energy supply module can be a solar module, a wind module or other module that can generate electricity through clean energy; the several power-consuming building loads are located in the same geographical area, and can be load equipment of several office buildings in the same park, or load equipment of several residential buildings in the same community; each power-consuming building load is powered by the city grid in the initial power supply stage. The grid and only one energy supply module (type of energy for power generation) are used for power supply. For example, the first power-consuming building load is powered by the municipal grid and the solar module, and the second power-consuming building load is powered by the wind module. When the energy output of the energy supply module is less than the energy consumption of the power-consuming building load, the power-consuming building load is powered by the municipal grid. When the energy output of the energy supply module can meet the energy consumption demand of the power-consuming building load, the power-consuming building load is powered by the energy supply module. In addition, the power supply distribution of the power-consuming building load and the energy supply module is determined by the power supply distribution logic recorded in the prior art.

[0064] Among them, Figure 1 As shown, the building microgrid cluster control system with multiple energy inputs is used to perform the following methods:

[0065] Step S100: Determine an energy consumption ratio threshold corresponding to each power-consuming building load in each historical time period based on the effective production capacity time period and the affected production capacity time period in a plurality of historical time periods according to the energy supply module corresponding to each power-consuming building load;

[0066] The energy supply module corresponding to the power-consuming building load is the energy supply module that supplies power to the power-consuming building load. The effective production time period is the time period preset within the historical time period during which the energy supply module can produce electricity (such as the daily effective production time period of the solar module is the time period between local sunrise and sunset). The affected production time period is the time period within the effective production time period during which the energy supply module cannot produce electricity due to external factors (such as the time period during which the solar module's production capacity decreases or cannot be produced due to weather reasons on a certain day). The length of the historical time period can be customized by the user (such as seven days).

[0067] Furthermore, step S100 includes steps S110 to S130:

[0068] Step S110: Obtain the energy supply module that supplies power to each electricity-consuming building load, and obtain the effective production time period in each historical time period to 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 m A list of effective production capacity time periods corresponding to the energy supply module supplying power to the mth electricity-consuming building load;

[0069] A m =(A m1 ,A m2 ,...,A mi ,...,A mj ); i = 1, 2, ..., j; j is the number of historical time periods; A mi The effective production capacity time period of the energy supply module that supplies power to the m-th electricity-consuming building load in the i-th historical time period;

[0070] 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 midnight of the current date. The length of each historical time period is equal.

[0071] Step S120: Obtain the energy supply module that supplies power to each electricity-consuming building load, and obtain the affected production capacity time period in each historical time period to obtain the affected production capacity time period list set B = (B1, B2, ..., B m ,...,B n ); among them, B m A list of affected production capacity time periods corresponding to the energy supply module supplying power to the m-th electricity-consuming building load;

[0072] B m =(B m1 ,Bm2 ,...,B mi ,...,B mj );B mi The affected capacity time period in the i-th historical time period for the energy supply module supplying power to the m-th electricity-consuming building load;

[0073] Step S130: Determine the energy consumption ratio threshold value Y corresponding to the mth power-consuming building load in the ith historical time period according to the effective power generation time period list set A and the affected power generation time period list set B. mi =(1-C mi / A mi )×Y0;

[0074] Wherein, Y0 is the preset initial energy consumption ratio threshold; 0<Y0<1;

[0075] If B mi ≥B 0i , then determine C mi =B mi -B 0i ; B 0i is the base value of the affected production capacity time period corresponding to the preset i-th historical time period;

[0076] If B mi <B 0i , then determine C mi is zero.

[0077] The energy consumption ratio threshold is determined based on the effective production capacity time period and the affected production capacity time period of the energy supply module corresponding to each electricity-consuming building load within several historical time periods. The determined energy consumption ratio threshold can be adaptively adjusted according to different historical time periods of different electricity-consuming building loads, rather than just a fixed threshold. This improves the flexibility of threshold comparison and makes the subsequent determination of the building load to be adjusted more accurate.

[0078] Step S200: determining the energy consumption ratio corresponding to each power-consuming building load in each historical time period based on the module energy consumption and total energy consumption of each power-consuming building load in each historical time period;

[0079] The module energy consumption is the energy produced by the energy supply module consumed by the power-consuming building load during the historical period, and the total energy consumption is the total energy consumed by the power-consuming building load during the historical period.

[0080] Further, step S200 includes steps S210 to S230:

[0081] Step S210: Obtain the module energy consumption of each power-consuming building load in each historical time period to obtain a module energy consumption list set D=(D1, D2, ..., Dm ,...,D n ); where D m The module energy consumption list corresponding to the mth electricity-consuming building load;

[0082] D m =(D m1 ,D m2 ,...,D mi ,...,D mj );D mi The module energy consumption of the mth electricity-consuming building load in the i-th historical time period;

[0083] Step S220: Obtain the total energy consumption of each power-consuming building load in each historical time period to obtain a first total energy consumption list set E=(E1, E2, ..., E m ,...,E n ); where E m is the total energy consumption list corresponding to the mth electricity-consuming building load;

[0084] E m =(E m1 ,E m2 ,...,E mi ,...,E mj );E mi is the total energy consumption of the mth electricity-consuming building load in the i-th historical time period;

[0085] Step S230: Determine the energy consumption ratio F corresponding to the mth power-consuming building load in the i-th historical time period based on the module energy consumption list set D and the first total energy consumption list set E. mi =D mi / E mi .

[0086] Step S300: Determine a building load to be adjusted from a plurality of power-consuming building loads based on the energy consumption ratio and energy consumption ratio threshold corresponding to each power-consuming building load;

[0087] The building load to be adjusted is the electricity-consuming building load that requires adjustment of the power supply module of the energy supply module, which means that under the current power supply stage, the energy output of the energy supply module cannot meet the energy consumption of the electricity-consuming building load, and the power supply of the municipal power grid accounts for too large a proportion of the energy consumption of the electricity-consuming building load. In order to save energy and reduce emissions and make full use of the energy supply module, it is necessary to adjust the energy supply module of the electricity-consuming building load.

[0088] Furthermore, step S300 includes steps S310 to S320:

[0089] Step S310: traverse the energy consumption ratio and energy consumption ratio threshold corresponding to the mth power building load in each historical time period. If F mi >Y mi , then the i-th historical time period is determined as the target historical time period corresponding to the m-th electricity-consuming building load;

[0090] Step S320: If the ratio of the number of target historical time periods corresponding to the mth power-consuming building load to j is less than a preset time period number ratio threshold, the mth power-consuming building load is determined as the building load to be adjusted.

[0091] The time period quantity ratio threshold is a number greater than 0 and less than 1.

[0092] If the ratio of the number of target historical time periods corresponding to the power-consuming building load to j is less than the preset time period number ratio threshold, it means that in most historical time periods of the power-consuming building load, the proportion of power supply using the municipal power grid is greater than the proportion of power supply using the energy supply module. In this case, the energy supply module of the power-consuming building load needs to be adjusted. Therefore, the power-consuming building load is determined as the building load to be adjusted.

[0093] Step S400: Based on the total energy consumption corresponding to any building load to be adjusted in each historical time period, and the module energy production and energy consumption ratio thresholds corresponding to other building loads to be adjusted in each historical time period, a target energy supply module corresponding to the building load to be adjusted is determined from a plurality of energy supply modules corresponding to other building loads to be adjusted;

[0094] Module production energy refers to the energy produced by the energy supply module during the historical period.

[0095] The target energy supply module is the energy supply module determined after energy supply adjustment is performed on the load of the building to be adjusted, and the target energy supply module supplies power to the load of the building to be adjusted.

[0096] Further, step S400 includes steps S410 to S450:

[0097] Step S410: determining the energy supply module corresponding to each building load to be adjusted as the energy supply module to be adjusted;

[0098] Step S420: Determine any building load to be adjusted as a first building load, and determine other building loads to be adjusted except the first building load as second building loads;

[0099] Step S430: Determine a target energy supply module corresponding to the first building load from among the energy supply modules to be adjusted based on the total energy consumption of the first building load in each historical time period and the module energy production of each energy supply module to be adjusted in each historical time period.

[0100] Wherein, step S430 includes steps S431 to S435:

[0101] Step S431: Obtain the total energy consumption corresponding to the first building load in each historical time period to obtain a second total energy consumption list G=(G1, G2, ..., G i ,...,G j ); where G i is the total energy consumption of the first building load in the i-th historical time period;

[0102] Step S432: Obtain the module production capacity corresponding to each energy supply module to be adjusted in each historical time period to obtain the module production capacity 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 The module capacity list corresponding to the p-th energy supply module to be adjusted;

[0103] H p =(H p1 ,H p2 ,...,H pi ,...,H pj );H pi The module energy production corresponding to the pth energy supply module to be adjusted in the i-th historical time period;

[0104] Step S433: According to the second total energy consumption list G and the module capacity list H corresponding to the pth energy supply module to be adjusted p , determine the energy production and consumption ratio M corresponding to the first building load and the pth energy supply module to be adjusted in the i-th historical time period i =H pi / G i ;

[0105] The energy-to-energy ratio indicates 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-to-energy ratio, the smaller the module energy production of the energy supply module to be adjusted is compared to the energy consumption of the first building load, and the less the energy supply module to be adjusted can meet the electricity demand of the first building load. Conversely, the larger the energy-to-energy ratio, the greater the module energy production of the energy supply module to be adjusted is compared to the energy consumption of the first building load, and the more the energy supply module to be adjusted can meet the electricity demand of the first building load.

[0106] Step S434: traverse the energy production and consumption ratios of the first building load and the pth energy supply module to be adjusted in each historical time period. If M i If the energy consumption ratio 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 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, the i-th historical time period is determined as the first historical time period corresponding to the first building load;

[0107] If M i If 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 is greater than the energy consumption ratio threshold of the building load 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.

[0108] On the other hand, as another embodiment of step S434, step S434 further includes step S4341:

[0109] Step S4341: If M i If the energy consumption ratio threshold of the building load to be adjusted corresponding to the pth energy supply module to be adjusted in the i-th historical time period is greater than the energy consumption ratio threshold, and is less than the preset maximum energy consumption ratio threshold, the i-th historical time period is determined as the first historical time period corresponding to the first building load.

[0110] Due to the principle of energy conservation, emission reduction and non-waste of energy, under 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 output of the energy supply module to be adjusted not to be too much greater than the energy consumption of the first building load. Otherwise, the excess output of the energy supply module to be adjusted will cause energy waste. Therefore, when determining the first historical time period, it is also necessary to set M i The energy consumption ratio is less than a preset maximum energy consumption ratio threshold, and the preset maximum energy consumption ratio threshold is greater than a maximum value among a plurality of energy consumption ratio thresholds.

[0111] Step S435: If the ratio of the number of 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, the energy supply module to be adjusted with the largest number of first historical time periods corresponding to the first building load is determined as the target energy supply module corresponding to the first building load, and step S440 is executed.

[0112] The energy supply module to be adjusted with the largest number in the first historical time period corresponding to the first building load is represented as the energy supply module to be adjusted whose energy production is closest 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.

[0113] On the other hand, step S435 further includes step S4351:

[0114] Step S4351: If the ratio of the number of first historical time periods corresponding to the first building load to j is less than a preset time period number ratio threshold, the first building load is determined as the third building load, and step S450 is executed.

[0115] 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 output of all 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-powering and redeployment.

[0116] Step S440: determining the first building load as the target building load;

[0117] Step S450: Select any one of the second building loads as the first building load, and return to step S430.

[0118] After the first building load determines the target energy supply module, the first building load is determined as the target building load; after the first building load fails to determine the target energy supply module, the first building load is determined as the third building load; then, one of the second building loads is selected again as the new first building load, and steps S430 to S450 are executed again until all the second building loads are determined as the first building load, indicating that all the building loads to be adjusted have completed the power supply adjustment of the target energy supply module.

[0119] 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.

[0120] Furthermore, step S500 includes steps S510 to S520:

[0121] Step S510: disconnecting each energy supply module to be adjusted from the corresponding building load to be adjusted;

[0122] Step S520 : Establishing a power supply connection between each target energy supply module and the target building load corresponding to the target energy supply module.

[0123] After determining the building load to be adjusted and the energy supply module to be adjusted, the power supply connection of each building load to be adjusted and each energy supply module to be adjusted is disconnected, and the target building load of the target energy supply module is reconnected with the target energy supply module so that the target energy supply module supplies power to the corresponding target building load.

[0124] In addition, after step S500, the building microgrid cluster control system with multiple energy inputs is further configured to execute steps S610 to S620:

[0125] Step S610: Determine an energy supply module to be adjusted that is not a target energy supply module among the plurality of energy supply modules to be adjusted as a first energy supply module;

[0126] Step S620: Allocate the first energy supply modules to the third building loads according to the power consumption of the third building loads and a preset energy matching rule.

[0127] The third building load is a building load to be adjusted for which power supply adjustment has not been completed, and the first energy supply module is an energy supply module to be adjusted that remains after the target energy supply module is determined.

[0128] Through preset energy matching rules, power supply adjustment is performed for several first energy supply modules and several third building loads. The energy matching rules can be power supply adjustment rules defined by users or power supply allocation rules in the prior art. For example, energy is distributed to several first energy supply modules according to the usage area or power consumption of the third building load (for example, if several first energy supply modules include two solar modules, three wind modules, and four hydropower modules, then after adjustment through the energy matching rules, one solar module, two wind modules, and one hydropower module are allocated to a certain third building load for supplying power to the third building load).

[0129] The multi-energy input building microgrid cluster control system of the present invention first determines the energy consumption ratio threshold corresponding to each power-consuming building load in each historical time period based on the effective production capacity time period and the affected production capacity time period of the energy supply module corresponding to each power-consuming building load in several historical time periods, then determines the energy consumption ratio corresponding to each power-consuming building load in each historical time period based on the module energy consumption and total energy consumption of each power-consuming building load in each historical time period, then determines the building load to be adjusted from several power-consuming building loads based on the energy consumption ratio and the energy consumption ratio threshold corresponding to each power-consuming building load, and determines the target energy supply module corresponding to any building load to be adjusted from several energy supply modules corresponding to other building loads to be adjusted based on the total energy consumption corresponding to any 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, finally disconnects the target energy supply module corresponding to each building load to be adjusted from the power supply connection, and establishes a power supply connection with the building load to be adjusted. The energy consumption ratio threshold is determined based on the effective production capacity time period and the affected production capacity time period of the energy supply module corresponding to each electricity-consuming building load within several historical time periods. The determined energy consumption ratio threshold can be adaptively adjusted according to different historical time periods of different electricity-consuming building loads, thereby improving the flexibility of threshold comparison and making 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 capacity of the target energy supply module matching 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 full utilization of the energy supply module.
