The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention.
[0042] Example 1
[0043] like Figure 1 As shown, a rapid modeling method for massive amounts of new energy includes the following steps:
[0044] S1. Obtain a pre-built integrated digital model of the power transmission and distribution network.
[0045] It should be noted that the integrated digital model of the power transmission and distribution network involved in this scheme covers all digital information of the power transmission and distribution network. This integrated digital model can include transmission and distribution network component models and equipment operating limit parameters, etc. More specifically, the transmission and distribution network component models can include transmission line parameters (resistance, reactance, conductance, susceptance), transformer parameters (leakage reactance, turns ratio, tap position), generator node parameters (active and reactive power output values), load node parameters (active and reactive power values); generator reserve capacity data; and equipment operating limit parameters can include: line rated current, transformer rated capacity, and generator maximum output (maximum active power output and maximum reactive power output). This method is applied to the integrated digital model of the power transmission and distribution network.
[0046] S2. Locate the new energy access point in the integrated digital model of power transmission and distribution network.
[0047] In this solution, step S2 specifically includes:
[0048] (1) Obtain all the busbars of the power grid in the integrated digital model of power transmission and distribution network to form a busbar set.
[0049] (2) Using bus key, voltage level, and grid zone as setting conditions, match the bus name, bus voltage, and grid zone of the bus with the set bus key, voltage level, and grid zone respectively;
[0050] Specifically, the method for matching the busbar name, busbar voltage, and power grid zone with the set conditions is as follows:
[0051] The method for matching bus names with set bus keywords: Let the string be A and the keyword be a. If Then it matches;
[0052] Method for matching bus voltage with the set voltage level: Set the highest voltage level to U. max The lowest is U min The node voltage is U. If U min <U<U max If , then it matches;
[0053] The method for matching power grid partitions with the configured power grid partitions is as follows: The partition is set as Z = {z1, z2, ...}, and the node partition is z b If z b If ∈Z, then it matches.
[0054] (3) Form a bus set Φ from the matched buses. b and for the bus set Φ b Perform hash mapping processing.
[0055] (4) Based on the set conditions, traverse the transformer branches, extract the two buses of each transformer branch, and perform a query based on the Hash mapping to determine whether both extracted buses exist in the bus set Φ. b If a transformer branch exists, it is selected as the target transformer; that is, the transformer branch consisting of the two selected busbars is used as the target transformer. If it does not exist, the transformer branch is ignored. This ultimately forms the target transformer set Φ. T .
[0056] (5) According to the PSD-BPA new energy access rules, the target transformer set Φ T As a given condition, a set of transformers at the new energy access point Φ is formed. NG Among them, the elements in the set of access point transformers are used as new energy access points.
[0057] Specifically, according to the PSD-BPA access rules for new energy sources, new energy generating units should be connected to the busbar of the substation with the corresponding voltage level. This substation busbar is the busbar that makes up the transformer branch.
[0058] Specifically, the target transformer set Φ T The set of access point transformers Φ is formed as a given condition. NG The method is as follows: Let the target transformer set be... Based on the new energy access requirements, the set of transformers at the access point can be determined. Φ NG ∈Φ T .
[0059] S3. Obtain the pre-built new energy unit model template.
[0060] Specifically, the new energy unit model template is divided into static model template, dynamic model template and parameter template; more specifically, it includes a comprehensive template consisting of generator-transformer groups, step-up transformers and connecting lines from low voltage to high voltage, as well as new energy unit model parameters; among them, the voltage level of the comprehensive unit ranges from low voltage to high voltage.
[0061] Specifically, this solution constructs static and dynamic model templates for new energy unit generators based on different types of new energy unit models and on-site wiring methods, according to the PSD-BPA power grid simulation calculation data specification, and saves them to the new energy template library. This includes:
[0062] (1) Static model of new energy unit, including bus node information, line information and transformer information.
[0063] Specifically, the bus node information includes node name, node type, reference voltage (covering all voltage levels), node zone, maximum active power output of new energy units, and actual active power output of new energy units; the line information includes line name, line rated current, per-unit resistance, per-unit reactance, and ground susceptance, covering the connection lines between each new energy unit and the collection station; the transformer information includes transformer name, rated capacity, leakage reactance, and transformer tap location, covering the transformer substations and step-up transformers of each new energy unit.
[0064] More specifically, the static model template example for new energy unit is as follows:
[0065]
[0066] (2) Dynamic model of new energy unit, including three new energy power generation models in PSD-ST program.
[0067] Specifically, the three new energy power generation models cover: fixed-speed wind turbines, doubly-fed wind turbines, direct-drive wind turbines, wind turbines with manufacturer-packaged parameters, and photovoltaic power generation.
[0068] Specifically, the three new energy power generation models included in the PSD-ST transient stabilization program are as follows:
[0069] ① The first set of new energy power generation models
[0070] Based on early models from the Western Electric Coordinating Committee (WECC) and GE (PSLF software), the first set of general-purpose models for wind turbines, photovoltaic power generation, and energy storage was established. The wind turbine models include three types: fixed-speed, GE doubly-fed, and GE direct-drive. The photovoltaic power generation model is a photovoltaic array paired with an inverter control model. The energy storage system is a chemical battery paired with an inverter control model.
[0071] ② The second set of new energy power generation models
[0072] In response to the frequent occurrence of grid disconnection of renewable energy sources in Zhangbei, Northwest China and other regions, a second set of doubly-fed, direct-drive wind turbine and photovoltaic power generation models was developed. These models can accurately and in detail simulate fault ride-through characteristics, providing reliable guidance for improving renewable energy consumption and ensuring the safe and stable operation of the power grid.
[0073] ③ The third set of new energy power generation models
[0074] To further support power grid calculations and reduce inconsistencies in calculation conclusions caused by differences in models and parameters, the PSD-ST and PSASP programs have standardized new energy models, establishing a third set of new energy power generation models. This model unifies the wind turbine model, photovoltaic power generation model, and energy storage system model across every control module and stage in both programs, and also achieves a one-to-one correspondence of relevant parameters. This provides a more accurate and reliable guide for power grid planning, design, and dispatching calculations.
[0075] After selecting the static model template for the new energy unit, set the single-unit capacity to determine the number of new energy units in the dynamic model.
[0076] Since the dynamic model and the static model are in one-to-one correspondence, the bus names in the dynamic model template of the new energy unit are consistent with those in the static template.
[0077] More specifically, the following is an example of a dynamic model template for new energy unit in this solution:
[0078]
[0079] This step ultimately forms a comprehensive system comprising generator sets, step-up transformers, and connecting lines from low to high voltage, as well as a new energy unit model template containing new energy unit model parameters, enabling complete management of static and dynamic models and parameters across multiple stages.
[0080] S4. Generate static and dynamic models of new energy sources in batches based on the new energy access point and new energy unit model template.
[0081] In this solution, step S4 specifically includes:
[0082] (1) Obtain the name of the access point transformer of the new energy access point;
[0083] (2) Based on the name of the access point transformer, the generated new energy static model and new energy dynamic model are based on the voltage level and refer to the name of the access point transformer. H or M or L is added after the name of the access point transformer as the bus name of different voltage levels in the new energy model. If multiple buses are connected to the same voltage level, A, B, C... are added after H, M, L to distinguish them.
[0084] It should be noted that the transformer at the access point must contain the highest voltage level of the new energy template data.
[0085] Taking Tianjin Chaoyin Temple Station as an example, this paper explains the new energy model generated based on the new energy unit model template.
[0086] Static new energy model:
[0087]
[0088] Dynamic New Energy Model:
[0089]
[0090] S5. After batch generating the static and dynamic models of new energy, add the static model of new energy to the .dat file; add the dynamic model of new energy to the .swi file.
[0091] In step 5, the batch-generated static models of new energy sources are added to the .dat file, and the batch-generated dynamic models of new energy sources are added to the .swi file, ultimately generating a PSD tidal flow and stability data file containing a massive amount of new energy sources.
