Abstract

This invention relates to a load coordination and allocation method at the energy source end. The method first determines the type of each energy station and its operating mode within a preset time period. Then, it sequences the energy stations according to their type and mode. Next, it calculates and sorts the comprehensive coefficients of the energy stations in each sequence, and finally allocates the load based on the sorting. Since the comprehensive coefficients controlling the sorting are calculated using performance coefficients, economic coefficients, safety coefficients, quality coefficients, and adjustment coefficients, this load coordination and allocation method at the energy source end aims at performance, economy, safety, and quality, achieving multi-objective requirements for load allocation. The method also promotes the reliability of load allocation through the combined use of optimization and load-addition mechanisms. Furthermore, by comparing the changes in energy stations within sequences in two adjacent time periods, it performs stabilization or shutdown procedures on energy stations to avoid large fluctuations in the energy grid and ensure the stable operation of the energy system.

Description

Technical Field

[0001] This invention relates to the field of energy distribution technology, and in particular to a method for coordinated distribution of loads at energy sources. Background Technology

[0002] Smart energy, with the deep integration of informatization and industrialization as its main focus, integrates information and communication technologies such as mobile internet and big data with various energy networks such as smart grids and thermal energy networks, creating close coupling and sharing of energy networks. At the source end, smart energy integrates distributed clean energy sources such as solar power plants, wind power plants, gas-fired combined heat and power (CHP) plants, and geothermal CHP plants, offering high flexibility.

[0003] Current power park benefit allocation methods focus on energy conservation optimization within the park and are based on contract management. This method, with energy conservation as its sole objective, has limitations in addressing load dispatch and allocation at the source end, and cannot meet the multi-objective requirements of load allocation. Summary of the Invention

[0004] Therefore, it is necessary to provide a method for coordinated allocation of energy source loads that can meet the multi-objective requirements of source load allocation.

Then, the energy stations are sequenced according to their type and mode. Next, the comprehensive coefficient of each energy station in the sequence is calculated and sorted. Finally, load allocation is performed based on the sorting. Since the comprehensive coefficient for controlling the sorting is calculated using performance coefficient, economic coefficient, safety coefficient, quality coefficient, and adjustment coefficient, this energy source-side load coordination and allocation method allocates load with performance, economy, safety, and quality as objectives, thus achieving multi-objective requirements for load allocation.

Let the quality coefficient at time k be the i-th energy station. Let be the adjustment coefficient at time k for the i-th energy station.

[0035] Where n is the number of energy stations in the sequence.

[0036] In one embodiment, steps S1422 and S1423 further include:

[0037] If not, and i = n, then proceed to step S1424;

[0038] S1424, determine whether the x-th energy station in the sequence has the potential to increase its load;

[0043] If energy station b is in the sequence within the first time period but not in the corresponding sequence within the second time period, then the exit command of energy station b is detected.

[0044] If the exit command is detected, energy station b will be exited; if the exit command is not detected, energy station b will be stabilized, and if the ranking of energy station b falls below a preset value, energy station b will be exited and an alarm will be triggered.

[0045] If there is an energy station c that is in the sequence within the second time period but not in the corresponding sequence within the first time period, proceed to step S140. Attached Figure Description

[0054] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0055] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a method for coordinated load allocation at an energy source, used to achieve multi-objective requirements for load allocation at the energy source. The coordinated allocation method includes the following steps:

[0056] S110: Obtain the operating modes of multiple energy stations within a preset time period.

[0057] It should be noted that energy stations include three types: power generation and energy storage energy stations, combined heat and power (CHP) energy stations, and power generation energy stations. Power generation and energy storage energy stations include two operating modes: power generation-led and energy storage-led. CHP energy stations include two operating modes: power generation-led and heating-led.

[0058] S120 assigns energy stations to corresponding sequences based on their type and operating mode.

[0059] Specifically, when the energy station is a power generation and energy storage energy station, if the operation mode is power generation-led, the energy station will be allocated to the power generation sequence; otherwise, the energy generated by the energy station will be stored.

[0060] When the energy station is a combined heat and power (CHP) energy station, if the operation mode is power generation-dominated, the energy station will be assigned to the power generation sequence; otherwise, the energy station will be assigned to the heating sequence.

[0061] When an energy station is a power generation station, it will be assigned to the power generation sequence.

[0062] S130, calculate the comprehensive coefficient of multiple energy stations in each sequence, and sort the multiple energy stations in each sequence according to the comprehensive coefficient.

[0063] S140, load allocation is performed on multiple energy stations in the sequence according to the sequence load demand and the order of multiple energy stations in the sequence.

[0064] By employing the aforementioned energy source-side load coordination and allocation method, the type of each energy station and its operating mode within a preset time period are first determined. Then, the energy stations are sequenced according to their type and mode. Next, the comprehensive coefficient of each energy station in the sequence is calculated and sorted. Finally, load allocation is performed based on the sorting. Since the comprehensive coefficient for controlling the sorting is calculated using performance coefficient, economic coefficient, safety coefficient, quality coefficient, and adjustment coefficient, this energy source-side load coordination and allocation method allocates load with performance, economy, safety, and quality as objectives, thus achieving multi-objective requirements for load allocation.

[0065] It should be explained that while the type of energy station is fixed, its operating mode can change. Therefore, in step S110, it is necessary to obtain the operating mode of the energy station within a preset time period. Furthermore, the length of the preset time period is determined based on actual circumstances, as long as frequent disturbances to the energy station can be avoided.

[0066] In addition, in this embodiment, the sequence includes a power generation sequence and a heating sequence, but those skilled in the art can apply the above-described coordination and allocation method to other sequences, such as energy storage sequences, based on the description of this embodiment, without limitation.

[0067] for Figure 2 It should be noted that the cogeneration energy station in the power generation sequence can generate heat, i.e., heating energy value. This heating energy value can be applied to the heating sequence or to energy storage, without any restrictions.

[0068] Please also refer to Figure 3 In some embodiments, the energy source-side load coordination and allocation method further includes the step of:

[0069] S150, obtain the heating energy value of the cogeneration energy station in the power generation sequence and the power generation energy value of the cogeneration energy station in the heating sequence.

[0070] It should be noted that for cogeneration power plants operating primarily in a power generation mode, after load allocation in the power generation sequence, the power plant will adjust its heating energy output after ensuring sufficient power generation. Similarly, in the heating supply sequence, after load allocation, the cogeneration power plant will adjust its power generation energy output after ensuring sufficient heating supply.

[0071] S160, determine the sequence load demand of the power generation sequence based on the total power generation load demand and the power generation energy value, and determine the sequence load demand of the heating sequence based on the total heating load demand and the heating energy value.

[0072] As can be understood, as mentioned above, for a cogeneration energy station that is primarily for heating, it is located in the heating sequence, but it can also generate electricity, and the electricity generated does not belong to the power generation sequence. Therefore, when calculating the sequence load demand, it is necessary to subtract the power generation energy value of the cogeneration energy station that is primarily for heating from the total power generation load demand.

[0073] Figure 3 Taking power generation as an example, first determine the total power generation load demand W and the power generation energy value U0 of the cogeneration energy station in the heating sequence. Next, calculate the sequence load demand, i.e., W-U0. After determining the sequence load demand, allocate the load to the energy stations in the sequence according to their order.

[0074] For example, if the first energy station is assigned load U1, after allocation, the remaining unallocated load is W-U0-U1. Similarly, the remaining unallocated load is equal to the total demand in the sequence minus the already allocated load.

[0075] In some embodiments, step S130 calculates the comprehensive coefficient of the energy station using formula (1).

[0076]

[0077] in, Let be the comprehensive coefficient of the i-th energy station at time k. Let be the performance coefficient of the i-th energy station at time k. Let be the economic coefficient of the i-th energy station at time k. Let the safety factor of the i-th energy station at time k be . Let be the quality coefficient of the i-th energy station at time k. Let be the adjustment coefficient of the i-th energy station at time k.

[0078] Please see Figure 4It should be noted that in this application, each energy station is equipped with a production control mechanism and a corresponding optimization control mechanism, and the optimization control mechanisms of multiple energy stations are connected to the central control mechanism to form an energy network.

[0079] In the above formula, the performance coefficient is used to consider the performance indicators of the energy station, the economic coefficient calculates the cost parameters of the energy station in real time to determine the economic coefficient level of the energy station relative to the energy grid, the safety coefficient is used to consider the operating status of the energy station's system and equipment, and the quality coefficient is used to evaluate the quality of the electricity or heat produced by the energy station and determine its quality level of connection to the energy grid. Thus, this energy source-side load coordination and allocation method allocates load with performance, economy, safety, and quality as objectives, achieving multi-objective requirements for load allocation.

[0080] In addition, the adjustment coefficient is a parameter introduced to facilitate adjustment under special circumstances, such as unit overhaul or special operating conditions, special allocation considerations, etc., and its default value can be set to 1.

[0081] It needs further explanation that the production control mechanism is the basic level of control, the optimization control mechanism is the intermediate level of control, and the overall control mechanism is the highest level of control.

[0082] The production control mechanism is used to transmit the equipment and system attributes of the energy station to the optimization control mechanism, and after receiving instructions from the upper level, to enable the energy station to coordinate and respond to the energy output requirements received by the energy station in accordance with its internal hierarchical control functions.

[0083] The optimized control mechanism can establish mathematical models of the system and equipment in the energy station, calculate, analyze, and evaluate the technical and economic indicators of the energy station and the performance indicators of the equipment online, and monitor the performance of the energy station's operation to obtain the economic coefficient and performance coefficient of the energy station. Simultaneously, the optimized control mechanism can deploy equipment condition monitoring and predictive maintenance systems, such as intelligent detection instruments, to monitor the status of system equipment in real time and analyze the health and safety coefficients of the system equipment. Furthermore, the optimized control mechanism can collect real-time output load information of the energy station, as well as its performance calculation and analysis, system equipment analysis, and other information to calculate the quality coefficient.

[0084] The central control unit can obtain information from the optimization control unit, allocate energy stations to the corresponding sequences, sort the energy stations in the sequences according to the comprehensive coefficient, then perform load allocation, and finally issue allocation instructions.

[0085] In some embodiments, step S130 further includes the step of: first determining the weights of the performance coefficient, economic coefficient, safety coefficient, quality coefficient and adjustment coefficient in formula (1), and then calculating the comprehensive coefficient.

[0086] It should be explained that the weights reflect the proportion of each coefficient among all coefficients. For example, if the performance coefficient has the largest weight, it means that the performance coefficient has the largest proportion, and the energy source load coordination and allocation method aims at performance. Similarly, for the economic coefficient, safety coefficient, and quality coefficient, the coefficient with the largest weight among the five coefficients indicates which coefficient is given the most weight in the allocation method.

[0087] Of course, the adjustment coefficient, as mentioned above, is a parameter introduced to facilitate adjustment in special circumstances. In special circumstances, its corresponding weight can also be increased to make adjustment more convenient.

[0088] In practical applications, the comprehensive coefficient is specifically calculated using formula (2).

[0089]

[0090] in, Let be the weight of the performance coefficient at time k. Let be the weight of the economic coefficient at time k. Let k be the weight of the safety factor at time k. Let be the weight of the quality coefficient at time k. The weight of the adjustment coefficient at time k.

[0091] It is understandable that by introducing weights for the coefficients, the weights of each coefficient can be assigned according to factors such as energy grid regulation policies, seasonal factors, and market factors, thereby increasing the adaptability of the comprehensive coefficients at different points in time and ensuring the stable operation of the energy grid.

[0092] Please see Figure 5 In some embodiments, step S140 includes:

[0093] S141, calculate the sequence load requirement and obtain the energy supply capacity of each energy station in the sequence at each moment within a preset time period.

[0094] Specifically, energy supply capacity includes power supply (generation) capacity and heating capacity.

[0095] S142, according to the order of multiple energy stations in the sequence, determine the load allocation of the energy stations at each moment in the preset time period based on their energy supply capacity.

[0096] It should be noted that the order of the energy stations will not change within the preset time period, but the load distribution may change.

[0097] Please see Figure 6 and Figure 7 In practical applications, step S142 includes:

[0098] S1421, after determining the load allocation of the i-th energy station, calculate the remaining load to be allocated.

[0099] The calculation of the remaining unallocated load is as follows: Figure 4 As shown above, no restrictions are imposed here.

[0100] It is understandable that i is an integer greater than or equal to 1, and when the number of energy stations in the sequence is n, i is less than or equal to n.

[0101] S1422, calculate whether the remaining load to be allocated is lower than the power supply capacity of the (i+1)th energy station. If yes, proceed to step S1423; if no, and i < n, let i = i+1, and repeat step S1422.

[0102] In other words, if the power supply capacity of the (i+1)th energy station cannot meet the requirements of the remaining load to be allocated, then skip that energy station and compare it with the next energy station in the ranking.

[0103] S1423, calculate whether the remaining load to be allocated is greater than the economic load limit of the (i+1)th energy station. If yes, allocate the remaining load to the (i+1)th energy station. If no, and i < n, let i = i+1 and return to step S1422.

[0104] It should be explained that frequent start-ups and shutdowns of each energy station incur certain economic costs, and if the load is too low after the energy station starts, it will lead to low efficiency and insufficient economic benefits. Only when the load is greater than the economic load limit but less than its energy supply capacity can economic losses be avoided while ensuring that the load demand is met.

[0105] In some embodiments, steps S1422 and S1423 further include:

[0106] If not, and i = n, then proceed to step S1424.

[0107] S1424, determine whether the x-th energy station in the sequence has the potential to increase load.

[0108] If yes, calculate the increaseable load value of the xth energy station, recalculate the remaining load to be allocated based on the increaseable load value, then let x = x + 1, and repeat step S1424; if no, let x = x + 1, and repeat step S1424.

[0109] Specifically, the remaining unallocated load is calculated by subtracting the increaseable load value to obtain the new remaining unallocated load. Furthermore, the allocation process ends once the remaining unallocated load is cleared to zero.

[0110] Steps S1422 to S1423 constitute an optimization mechanism, which involves finding an energy station among the unassigned loads that has sufficient power supply capacity and meets the requirements of its operating range, and then allocating the remaining unassigned load to that energy station. Step S1424 is a load-adding mechanism, which, after the optimization mechanism fails to find an energy station that meets the requirements, sorts the remaining unassigned loads in sequence, and allocates the remaining unassigned loads to multiple energy stations sequentially according to the load-adding value of each energy station, until the load allocation is completed.

[0111] It should be noted that, under normal circumstances, energy stations have a certain load-adding potential. If, in the load-adding mechanism, when the load is allocated to the xth energy station, the xth energy station has not yet been allocated any load, then since the remaining unallocated load has been reduced after recalculation, the optimization mechanism can be returned until an energy station that meets the requirements is found.

[0112] It is understandable that x is an integer greater than or equal to 1, and x is less than or equal to n.

[0113] It should also be noted that the initial value of x in step S1424 is 1, meaning that the detection of whether an energy station with load capacity has increased is started from the first energy station in the sequence. Furthermore, the sequence load demand can be determined based on actual demand and the energy station's supply capacity; therefore, it is generally unlikely that the sequence load demand will exceed the sum of the supply capacities of all energy stations in the sequence. In other words, under normal circumstances, the sequence load demand can be allocated using the above allocation method.

[0114] Additionally, it should be explained that the load potential is derived through the aforementioned optimization control layer calculation and analysis, specifically based on the real-time output load information of the energy station, as well as the energy station performance calculation and analysis, system equipment analysis, and other information.

[0115] In some embodiments, the energy source-side load coordination and allocation method further includes the step of:

[0116] Compare multiple energy stations in the corresponding sequence within the first and second consecutive time periods.

[0117] If energy station a exists in the sequence corresponding to both the first and second time periods, then energy station a will be stabilized.

[0118] If energy station b is in the sequence within the first time period but not in the corresponding sequence within the second time period, then the exit command for energy station b is detected.

[0119] Specifically, if an exit command is detected, energy station b will be exited; if no exit command is detected, energy station b will be stabilized, and if the ranking of energy station b falls below a preset value, energy station b will be exited and an alarm will be triggered.

[0120] If there is an energy station c in the sequence of the second time period, but not in the corresponding sequence of the first time period, proceed to step S140.

[0121] It should be explained that the first time period precedes the second time period, and the first time period can be a period that is currently being executed, while the second time period is a period that has not yet been executed. The sorting and allocation within the second time period are predicted values. Since the demand of the energy grid is relatively stable, a predictive approach can be used for pre-setting.

[0122] Stabilizing an energy station means maintaining its original state. For example, if the energy station is on during the first time period, it may remain on during the second time period, although the sequence of events may change.

[0123] For energy station b, the exit command means that energy station b will be removed from the energy grid. If an exit command is detected, it indicates that energy station b may be experiencing shutdown, equipment failure, or manual intervention. Since energy station b's ranking is below the preset value, it means that energy station b's overall coefficient is low, and the impact of its exit will be minimal; therefore, energy station b can be removed.

[0124] Energy station c is a newly added energy station in the sequence, and the corresponding sequence has been confirmed. At this time, it can be processed directly according to step S140.

[0125] Meanwhile, it should be noted that if the sequence in the second time period only includes multiple energy stations a and c, and there is no energy station b, in order to ensure the stability of load distribution, the original sorting and load distribution can be maintained. After generating excess unallocated load in the sequence, if energy station c meets the requirements of steps S1422 to S1423, the remaining unallocated load can be allocated to energy station c.

[0126] In summary, the advantages of the energy source-side load coordination and allocation method in this application include:

[0127] 1. This energy source-side load coordination and allocation method allocates load with performance, economy, safety and quality as objectives, realizing the multi-objective requirements of load allocation. Moreover, the calculation method of the comprehensive coefficient allows the load allocation to be sorted according to the optimal coefficient within a preset time period.

[0128] 2. The calculation of the comprehensive coefficient introduces the weights of each coefficient, so as to adjust the priority of the coefficients according to the regulatory policies, seasonal factors, market factors and accidental factors, thereby improving the adaptability of the comprehensive coefficient calculation.

[0129] 3. During the load allocation process, an optimization mechanism and a load-addition mechanism are adopted to fully allocate the load according to the sequence order while avoiding economic losses;

[0130] 4. By comparing the changes of energy stations in the corresponding sequences during the first and second time periods, and then taking corresponding measures based on the changes, the stability of the load distribution of the entire energy grid can be ensured and large-scale fluctuations can be avoided.

[0131] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0132] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
