Description

Technical Field

[0001] This invention relates to the field of power system calculation technology, and in particular to a method and apparatus for calculating the unadjustable zone of load during joint dispatch of multiple generating units. Background Technology

[0002] For a given power generation unit, there are often multiple grid-connected units. Each of these units has its own non-adjustable active load range. These non-adjustable ranges are usually determined by the mechanical performance of the unit, such as the low-efficiency range of thermal power units, the vibration range of hydropower units, and load ranges that technicians consider unsuitable for long-term operation due to poor operating conditions or other reasons.

[0003] In related technologies, for generator sets, the unadjustable zone may change when operating conditions change. Technicians can adjust the unadjustable zone according to the actual operating conditions of the unit. When a power generation unit has multiple grid-connected units, and each unit has one or more unadjustable load zones, these unadjustable zones need to be integrated and calculated to clarify the adjustable range and unadjustable zone of active power load under the joint dispatch of multiple units. In the traditional way, when reporting load output, the on-duty personnel usually specify the expected power output of a single unit and then accumulate them to obtain the total target output, or use a top-down approach to first give the target output and then decompose it to each grid-connected unit to verify whether it belongs to the adjustable zone. However, the above technical solutions have high requirements for the operating experience of technicians, which can easily lead to calculation omissions. The calculation process needs to be repeatedly adjusted during the decomposition process, which lacks systematicity and makes it difficult to guarantee the global optimum. If the comprehensive unadjustable zone cannot be accurately described, it will lead to a reduction in the load adjustment range of the power generation unit, reducing the load adjustment capability and flexibility. Based on the above analysis of the development status of this technology field, the existing technologies lack a mathematical and automated process to calculate the unadjustable load zone of multi-unit joint scheduling using interval addition and combination union operations.

Detailed Implementation

[0013] To enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this document.

[0014] Method Example 1 According to embodiments of the present invention, a method for calculating the unadjustable zone of load during joint scheduling of multiple generating units is provided. Figure 1 This is a flowchart of the multi-unit joint scheduling load unadjustable zone calculation method according to an embodiment of the present invention, such as... Figure 1 As shown, the method for calculating the unadjustable zone of load in multi-unit joint scheduling according to an embodiment of the present invention specifically includes: In step S110, the defined interval addition and combination union operations are obtained, specifically including: Let there be sets A = {x | a1 ≤ x ≤ a2}, B = {x | b1 ≤ x ≤ b2}, and C = {x | c1 ≤ x ≤ c2}; where a, b, and c are specific numerical values. Define the interval addition operation A&B={x∈N|a1+b1≤x≤a2+b2}, A&B&C=(A&B)&C.

[0015] The combination union operation can also be derived from two sets. Let M = {x | x ∈ A1 ∨ x ∈ A2} and N = {x | x ∈ B1 ∨ x ∈ B2}, where A1, A2, B1, and B2 are also sets, and ∨ represents "or". Then the combination union operation M ⊕ N = {x | x ∈ (A1 & B1) ∨ (A1 & B2) ∨ (A2 & B2) ∨ (A2 & B2)}. The same logic applies to M = {x | x ∈ A1 ∨ x ∈ B1 ∨ x ∈ C1}. =M; Therefore, by extension, for a set M = {x | x ∈ A1 | x ∈ A2 | … x ∈ Am}, N = {x | x ∈ B1 | x ∈ B2 | … x ∈ Bn}; Define the combination union operation .

[0016] The above set definition forms the theoretical basis for subsequent operations and is independent of the naming conventions of subsequent parameters.

[0017] In step S120, the load capacity of each unit is read, and the joint dispatch load capacity is obtained using interval addition, specifically including: Calculate the joint dispatch load capacity P = P1 & P2 & … Pi, where Pi represents the load capacity of the i-th unit.

[0018] In step S130, the unadjustable load range of each unit is read, and the adjustable load range of each unit is obtained through complement operation, using the load capacity of each unit as a reference set. Specifically, this includes: For the current i-th unit, the complement operation M is performed. i = Pi N i Calculate the load adjustable range of the i-th generating unit, which is defined as the complement of Ni in the set Pi, where Ni = N. i1 ∪N i2 ∪N i3 …N ij Indicates the non-adjustable load zone of unit i, N ij This represents the j-th section of the load that is not adjustable for the i-th generating unit; Let M be the result of the current complement operation. i = M i1 ∪M i2 ∪M i3 …M ik , of which M ik Let k represent the adjustable load zone of the i-th unit, and then we can obtain the adjustable load zones of each unit.

[0019] In step S140, based on the adjustable load range of each unit, a combined union operation is used to obtain the jointly dispatched adjustable load range. Using the jointly dispatched load capacity as a reference set, a complement operation is used to obtain the jointly dispatched non-adjustable load range, specifically including: Calculate the adjustable load zone M for joint scheduling: M1⊕M2⊕M3…⊕M i ; In the definition of a set, ∨ is equivalent to the union ∪ in set operations.

[0020] Calculate the unadjustable zone N of the joint scheduling load. P M means the complement of M in set P.

[0021] Therefore, for the same power generation unit or power dispatching unit, when each unit has one or more unadjustable load zones, the adjustable zone of a single unit is obtained by using complement calculation, and then the adjustable zones are integrated and calculated to obtain the joint dispatch adjustable zone. Finally, the unadjustable zone of the joint dispatch is obtained by using complement calculation again.

[0022] The method further includes: In step S150, the load adjustable zone of each unit is actually directly used as input data in the calculation logic and program design; according to actual needs, the result of joint scheduling adjustable zone can be output by integrated calculation. For power generation units using the AGC (Automatic Generation Control and Dispatch) program, the results of the non-adjustable load zone under joint dispatch are used as input data for the AGC program to adjust the unit's power generation load. For power generation units not using AGC dispatch, the above calculation results can be used as reference data for operators to report power generation output.

[0023] The above technical solutions of the embodiments of the present invention will be illustrated with reference to the following accompanying drawings.

[0024] Figure 2 This is a schematic diagram of the program calculation flow according to an embodiment of the present invention, such as... Figure 2 The diagram illustrates the program flow for the optimized calculation method of the unadjustable load zone in multi-unit joint dispatching. Specifically, it defines the number of grid-connected units X and performs iterative calculations. Preferably, when the number of grid-connected units or the unadjustable load zone parameters change, the results of previous calculations can be directly superimposed. For example, if a new unit i is added, the calculated unadjustable load zone M for joint dispatching from units 1 to i-1 is directly used to calculate M = M⊕M. i As the latest result.

Grid-connected operation parameters of the two generating units

[0026] According to the calculation method for the unadjustable load zone in joint dispatch of multiple generating units, the program reads the number of grid-connected generating units, load capacity, and unadjustable zone parameters for each unit. The calculation of the unadjustable load zone in joint dispatch is as follows: Calculate the joint scheduling load capacity P = P1 & P2 = {x | 0 ≤ x ≤ 100}; Calculate the load adjustable zone M1 of the first unit, M1 = P1 N1= M 11 ∪M 12 = {x | 2 < x < 15} ∪ {x | 30 < x ≤ 50}; the set {x | 2 < x < 15} is similar to A1 in the definition, and the set {x | 30 < x ≤ 50} is similar to A2 in the definition; Calculate the load adjustable zone M2 of the second unit, M2 = P2 N2= M 21 ∪M 22 = {x | 3 < x < 15} ∪ {x | 35 < x ≤ 50}; the set {x | 3 < x < 15} is similar to B1 in the definition, and the set {x | 35 < x ≤ 50} is similar to B2 in the definition; Calculate the adjustable load zone M for joint scheduling: M1⊕M2= {x∣5<x<30}∪{x∣37<x<50}∪{x∣33<x≤65}∪{x∣65<x≤100}={x∣5<x<30}∪{x∣33<x≤100}; Calculate the unadjustable zone N of the joint scheduling load. P M={x∣0≤x≤5}∪{x∣30≤x≤33}.

[0027] Method Example 3 According to an embodiment of the present invention, assuming that three generating units of a certain power generation unit are operating in parallel with the grid at a certain time, their power generation capacity and non-adjustable zone parameters are shown in Table 2: Table 2. Grid-connected operation parameters of the three generating units

[0028] According to the calculation method for the unadjustable load zone in joint dispatch of multiple units, the program reads the number of grid-connected units, load capacity, and unadjustable zone parameters of each unit. The calculation of the unadjustable load zone in joint dispatch is as follows: Calculate the joint scheduling load capacity, P = P1 & P2 & P3 = {x | 0 ≤ x ≤ 150}.

[0029] Calculate the adjustable load zones for each unit, M1, M2, and M3.

[0030] Calculate the adjustable load zone for joint scheduling, M = M1⊕M2⊕M3 = {x∣24<x<148}.

[0031] Calculate the unadjustable zone of the joint dispatch load, N= P M={x∣0≤x≤24}∪{x∣148≤x≤50}.

[0032] The calculation results are used as reference data for AGC load adjustment, so that AGC load commands are accurately issued within the adjustable range.

[0033] In summary, addressing the existing problems, this invention presents a method for calculating the unadjustable load zone in multi-unit joint dispatching. It employs a mathematical and automated process, utilizing interval addition and combination union operations to accurately describe the adjustable range of active power load and the unadjustable load zone in multi-unit joint dispatching. The calculation scheme is simple and convenient, allowing operators to quickly and accurately obtain comprehensive unadjustable zone data for each grid-connected unit within a power generation unit, given the existence of multiple unadjustable zones. When operating conditions change or other reasons alter the unadjustable zone, technicians can flexibly adjust it and quickly obtain new and accurate unadjustable zone data. For power generation units using AGC (Automatic Generation Control) dispatching, this scheme uploads correct unadjustable zone data to the dispatching system in real time. When the number or information of grid-connected units changes, the program automatically calculates and uploads new data to ensure the accurate issuance and execution of dispatching load commands.
