[0042] This application provides a power system model simulation test method, device, terminal, and medium to solve the technical problem of low efficiency in existing power system simulation model test comparison.
[0043] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0044] First, a detailed description of an embodiment of a power system model simulation and testing method provided in this application is as follows:
[0045] Please see Figure 1 The first aspect of this application provides a power system model simulation test method, including:
[0046] Step 101: Obtain the first power system simulation model and run the simulation based on the first power system simulation model to obtain the first simulation dataset.
[0047] The first power system simulation model was constructed using a pre-set first simulation software.
[0048] It should be noted that, taking the model simulation scenario of a photovoltaic grid-connected power plant power system as an example, RTDS is first used as the primary simulation software to construct a standard photovoltaic power plant topology model as the first power system simulation model, including the AC grid, step-up transformer, combiner transformer, inverter, BOOST converter, and PV modules. The basic parameters are: AC grid voltage level of 220kV, frequency of 50Hz, DC bus voltage of 800V, and rated grid-connected power of 1MW. Then, based on the established photovoltaic power plant topology model, operational simulation is performed to establish RTDS datasets under steady-state and fault-state conditions, i.e., the first simulation dataset M. i,jThis dataset can serve as a comparison standard dataset, where fault states include, but are not limited to, three-phase short-circuit faults in AC power grids, two-phase short-circuit faults in AC power grids, and single-phase short-circuit faults in AC power grids. In the first simulation dataset M... i,j In the table, i = 1, 2, ..., K represents the data category, including PV module port voltage and current, DC bus voltage, inverter output port voltage and current, grid connection point voltage and current, and control loop output signal; j = 1, 2, ..., n represents the data points at different times.
[0049] In this embodiment, the first simulation software can be a mainstream simulation software such as RTDS, RT-LAB, MATLAB, PSCAD, etc.
[0050] Step 102: Establish a mapping relationship between the components of the second simulation software and the components of the first power system simulation model. Through topological mapping, convert the first power system simulation model into a second power system simulation model based on the second simulation software.
[0051] It should be noted that, based on the first power system simulation model in step 101, the photovoltaic model of RTDS is transformed into a second power system simulation model based on the second simulation software using the topology mapping relationship. In this embodiment, the second simulation software is a different simulation software from the first simulation software, and is generally a self-developed simulation software.
[0052] In some embodiments, such as Figure 2 As shown, the steps in step 102 of this embodiment may include:
[0053] Step 1021: Read the component information of each component in the first power system simulation model to obtain the first component set;
[0054] Step 1022: Obtain the preset initial component set of the second simulation software, match the components in the initial component set with the first component set, and establish a mapping relationship between the components matched from the initial component set and the components in the first component set to obtain the second component set that is mapped to the first component set, so as to obtain the second power system simulation model based on the second component set.
[0055] It should be noted that, for example, A is an RTDS model. A contains descriptions of the relevant component information in the model. This component information includes: the type, quantity, location, and initial parameter values of electrical / control components, abstracted as set 'a', and the connection relationships between the components, abstracted as set 'alpha'. When transforming A into model B in the self-developed simulation software based on the mapping relationship, the main steps are as follows:
[0056] 1. First, the information of set a is automatically read through programming and instantiated into the corresponding information of set b in the self-developed simulation software. The information of set b contains the type, quantity and initial value information of the corresponding electrical / control components.
[0057] 2. Secondly, based on the component connection relationship information described by the alpha set, the alpha is automatically read in the self-developed software and the corresponding beta set is generated. The components in the b set are connected according to the relationship described by the beta set, and finally the model B in the self-developed software is obtained.
[0058] In the above example, the mapping relationship means that A corresponds to B, a corresponds to b, and alpha corresponds to beta. That is, for the photovoltaic model in RTDS, it can be transformed into a model in the self-developed simulation software through the above mapping relationship.
[0059] Step 103: Perform an operational simulation based on the second power system simulation model to obtain the second simulation dataset.
[0060] It should be noted that, maintaining the same simulation conditions as in step 101, the second power system simulation model obtained in step 102 is simulated in the second simulation software in the same way to obtain the second simulation dataset N. i,j This can be used as a comparison dataset. The second simulation dataset N... i,j In the table, i = 1, 2, ..., K represents the data category, including PV module port voltage and current, DC bus voltage, inverter output port voltage and current, grid connection point voltage and current, and control loop output signal; j = 1, 2, ..., n represents the data points at different times.
[0061] Step 104: Based on the comparison results of the first simulation dataset and the second simulation dataset, determine the simulation test results of the second power system simulation model.
[0062] It should be noted that by comparing the results of the first simulation dataset and the second simulation dataset, the differences between the self-developed simulation software corresponding to the second simulation dataset and the mainstream simulation software corresponding to the first simulation dataset can be determined, thereby determining whether the simulation test results of the second power system simulation model are qualified.
[0063] More specifically, such as Figure 3 As shown, the process of step 104 in this embodiment may include:
[0064] Step 1041: Using the correlation coefficient calculation formula, based on the first simulation data and the second simulation dataset, calculate the correlation coefficients between similar simulation data in the first simulation data and the second simulation dataset according to the type of simulation data.
[0065] Step 1042: Based on the correlation coefficients of various similar simulation data and combined with the preset weight coefficients, calculate the comprehensive correlation coefficient between the first simulation data and the second simulation data set. Based on the comparison result of the comprehensive correlation coefficient and the preset judgment threshold, determine the simulation test result of the second power system simulation model.
[0066] The formula for calculating the correlation coefficient mentioned in this embodiment is as follows:
[0067]
[0068] In the formula, ρ i M is the correlation coefficient between the i-th type of simulation data in the first simulation data and the second simulation data set. i,j Let N be the value of the j-th data point of the i-th type of simulation data in the first simulation dataset. i,j Let be the value of the j-th data point of the i-th type of simulation data in the second simulation dataset, where i represents the index of the simulation data type, j represents the index of the data point, and n is the number of data points.
[0069] The correlation coefficient ρ for each data category can be calculated using the formula above. i , i = 1, 2, ..., K.
[0070] Recalculate dataset M i,j and N i,j The comprehensive correlation coefficient between the two is used as the final weighted correlation coefficient. The calculation formula can be: Where α i ∈(0,1) represents the weighting coefficients corresponding to the correlation coefficients of each data category. The calculated weighted correlation coefficients range from -1 to 1. A weighted correlation coefficient of 1 indicates that the simulation results of the two station models are completely consistent. The closer the value is to 1, the more consistent the simulation results of the two models are. In practice, the threshold ρ can be selected according to the requirements of different scenarios. TH For example, take ρ TH =0.95. When the calculated weighted correlation coefficient is greater than 0.95, the simulation results of the two simulation models are considered to be consistent, that is, the accuracy of the self-developed simulation software has reached the level of existing mainstream simulation software.
[0071] This application provides a general procedure for systematically testing and comparing power system models, and introduces a weighted correlation coefficient. This method scientifically reflects the differences between different simulation datasets. Using the method provided in this application, the efficiency of the model comparison and testing process can be improved.
