Description

Technical Field

[0001] This invention relates to a method and system for identifying asynchronous power sources that participate in the transient power angle stability control of a power grid, belonging to the field of power system automation technology. Background Technology

[0002] With the grid connection of a large number of new energy generating units, the low inertia and low immunity of these units have had a profound impact on the power angle stability of the power grid. After a grid fault occurs, the torque balance of the generator rotor is disrupted, and the power of the prime mover exceeds the electromagnetic power of the generator, causing the generator rotor to accelerate and lose synchronization.

[0003] When dealing with the problem of transient power angle instability of the power grid caused by fault disturbances, traditional control measures generally adopt methods such as generator tripping. During the transient process, the generator tripping strategy disconnects the synchronous generators in the leading group, thereby reducing the mechanical power and overall inertia of the leading group, reducing the acceleration kinetic energy of the power grid, and ensuring that the power grid resumes safe and stable operation.

[0004] However, relying solely on traditional generator tripping methods to address the risks of high volatility and uncertainty brought about by the new power system remains insufficient. On the one hand, traditional safety control measures for synchronous generator tripping lead to a reduction in generator equipment lifespan, and the cost of starting and stopping synchronous generators is high, resulting in a significant price to pay for ensuring grid safety and stability. On the other hand, due to the large-scale integration of new energy units, a large number of synchronous generators have been replaced, significantly reducing traditional control resources, and the traditional generator tripping capacity can no longer meet the grid's operational needs. Therefore, exploring the participation of asynchronous power sources in grid transient power angle stability control has become one of the primary objectives in addressing grid transient power angle instability, but currently, there are no corresponding methods. Summary of the Invention

Attached Figure Description

[0042] Figure 1 A flowchart for a non-synchronous power source mining method for participating in the transient power angle stability control of the power grid. Detailed Implementation

[0043] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0044] like Figure 1 As shown, the method for identifying asynchronous power sources participating in the transient power angle stability control of the power grid includes the following steps:

[0045] Step 1: Group the asynchronous power sources within the grid under fault conditions; where the fault is one that can cause transient power angle instability of the unit.

[0046] Step 2: Based on the results of asynchronous power source grouping within the network under fault conditions, determine the response direction of the asynchronous power source during the transient process.

[0047] Step 3: Calculate the control cost sensitivity of the asynchronous power supply replacement switching quantity under fault conditions;

[0048] Step 4: Based on preset rules and control cost sensitivity, screen asynchronous power sources and use the screened asynchronous power sources as control resources to participate in the transient power angle stability control of the power grid, with the response direction serving as the control direction of the control resources.

[0049] The above method groups asynchronous power sources that can cause transient power angle instability faults in generating units. Based on the grouping results, it determines the response direction of asynchronous power sources during the transient process, calculates the control cost sensitivity of the asynchronous power source replacement tripping quantity under the fault, and screens asynchronous power sources. The screened asynchronous power sources are used as control resources to participate in the transient power angle stability control of the power grid, and the response direction is used as the control direction of the control resources. This realizes the discovery of asynchronous power sources that can participate in the transient power angle stability control of the power grid.

[0050] There are many asynchronous power sources in the power grid. Based on the power grid conditions, identify the asynchronous power sources that can be used to address transient power angle stability issues. Generally, this refers to asynchronous power sources that can meet the response speed requirements for transient power angle stability issues, and must meet the response speed requirements in the hundreds of milliseconds.

[0051] During the acquisition process, a binary table D can be established regarding the adjustable active power output and response speed (expressed in time) of the asynchronous power source. n (P n_adjust ,t n For example, asynchronous power sources such as DC control and protection systems, new energy converter control, and energy storage power regulation in the power grid are controlled by power electronic equipment, which can complete power regulation within a few hundred milliseconds. This can provide support for transient processes after a fault, and therefore can be included in the candidate set B for dealing with transient power angle instability of the power grid. n middle.

[0052] For the target power grid structure, time-domain simulation is performed on the fault disturbances described in the second-level safety and stability standard specified in the "Guidelines for Power System Safety and Stability". If the fault causes transient power angle instability of the synchronous generator, the fault is placed into the fault set F. k This allows for the construction of a fault set capable of causing transient power angle instability in generating units. Simulation analysis is then used to determine the traditional safety control unit tripping quantity G required to ensure the safe and stable operation of the power grid after a fault occurs. k .

[0053] Traverse the fault set, and for each fault, group the asynchronous power sources within the network under the fault. The specific process can be as follows:

[0054] 1) Based on the extended equal area rule, the synchronous generator sets under fault conditions are grouped; among them, the synchronous generator sets are divided into the leading group of synchronous generator sets and the remaining group of synchronous generator sets.

[0055] Based on the identification of the trajectory dominance mode in the extended equal area law, the complementary group inertia center-relative motion transformation is applied to each time section to aggregate the trajectory into a series of equivalent single-machine infinite system image trajectories. For unstable trajectories, among all possible complementary groups of multi-machine disturbed trajectories, at least one pair of complementary groups has crossed the dynamic saddle point in relative motion, which can determine the grouping structure of the grid synchronous units after the fault occurs.

[0056] This step can use FASTEST software to perform simulation analysis to obtain the grouping results of the synchronous generator sets under each fault. The synchronous generator sets located in the leading group of the synchronous generator sets are denoted as S, and the synchronous generator sets located in the remaining groups of the synchronous generator sets are denoted as A.

[0057] 2) Based on the grouping results of the synchronous generator and the oscillation center section of the power grid after the fault, the asynchronous power sources in the grid under the fault are grouped; among them, the asynchronous power sources in the grid are divided into the leading asynchronous power source group and the remaining asynchronous power source group.

[0058] The specific process can be as follows:

[0059] 21) Based on the grouping results of the synchronous generator sets and the oscillation center section of the power grid after the fault, the power grid is divided into the leading group and the remaining group; among them, the power grid group where S is located is the leading group, the power grid group where A is located is the remaining group, S is the synchronous generator set in the leading group, and A is the synchronous generator set in the remaining group.

[0060] 22) Assign asynchronous power sources in the leading group of the power grid to the leading asynchronous power source group, and assign asynchronous power sources in the remaining groups of the power grid to the remaining asynchronous power source group.

[0061] After obtaining the asynchronous power source grouping results, the response direction of the asynchronous power source in the transient process can be determined, that is, to reduce the active power output of the asynchronous power source in the leading asynchronous power source group and increase the active power output of the asynchronous power source in the remaining asynchronous power source group.

[0062] Time-domain simulation can be used to calculate the control cost sensitivity of asynchronous power supply replacement switching quantity under fault conditions.

[0063] Within the adjustable range of active power of each asynchronous power source, ΔP n To adjust the power adjustment step size, the asynchronous power supply D... nThe active power is simulated a times from minimum to maximum value, and t is performed after the fault occurs. n Time taken The measures were taken to determine the G required to ensure the safe and stable operation of the power grid at each step. k The amount that can be reduced ΔG k The asynchronous power supply D can be derived. n The set of mappings of the impact of traditional switching control measures within the adjustable range is as follows: According to asynchronous power supply D n The actual real-time active power output and adjustable capacity are used to calculate the reduction in power output during tripping (based on the results obtained from software simulation); if the asynchronous power supply D... n If the sum of actual active power output and adjustable power satisfies the following inequality, then according to P... nmin +(a-1)ΔP n calculate

[0064] P nmin +(a-1)ΔP n ≤P n_real +P n_adjust <P nmin +aΔP n

[0065] Where Pn_real is the asynchronous power supply D n In reality, there is effort and contribution, P n_adjust For asynchronous power supply D determined by response direction n Adjustable amount, P nmin Non-synchronous power supply D n The minimum active power, To address the asynchronous power supply D during a fault n The amount of grid tripping can be reduced in the a-th simulation;

[0066] The asynchronous power source D is set according to the actual situation of the power grid. n The cost of active power adjustment The control cost of traditional safety-controlled generator disconnection (safety and stability control system action to disconnect generator set) The control cost sensitivity can be calculated using the following formula:

[0067]

[0068] in, Non-synchronous power supply D n The control cost and sensitivity of the replacement cutting quantity. Non-synchronous power supply D n The adjustment resulted in a reduced cutting volume.

[0069] Calculate B nAfter replacing the control cost sensitivity of all asynchronous power sources with the switching quantity, the control cost sensitivity is iterated. If the control cost sensitivity is greater than the threshold, the corresponding asynchronous power source is used as the control resource to participate in the transient power angle stability control of the power grid, and the response direction is used as the control direction of the control resource.

[0070] The threshold for comparing sensitivity to control cost is generally set to 0. Non-synchronous power supplies with a value greater than 0 are placed in the adjustable control resource group. The others are placed in the resource control group without adjustment. In the event of a relative fault, the power grid will adjust accordingly. The adjustment amount for each of the control resources is P. n_adjust The corresponding reduction in the number of cutters is Total reduction in cutting volume:

[0071]

[0072] in, for The total number of generator trips that can be reduced by non-synchronous power supplies is represented by C, which is the tripping margin and is set based on scheduling experience.

[0073] The asynchronous power sources obtained based on the above methods can participate in the transient power angle stability control of the power grid. By making full use of the abundant asynchronous power sources in the power grid, the amount of power generation cut-off after a fault is reduced to the minimum. While increasing the total control resources of the power grid, the control cost of the power grid is reduced, and the ability of the power grid to cope with transient power angle instability after a fault is improved, thus meeting the requirements for safe and stable operation of diversified power grids.
