Description

Technical Field

[0001] The present invention relates to the field of hydropower cluster division, and in particular to a hydropower cluster division method suitable for power dispatching of hydropower-enriched power grids. Background Art

[0002] At present, under the "basin, cascade, rolling, comprehensive" development model, a large-scale basin cascade power station group has been formed. Unlike thermal power, the cascade hydropower station group sequentially and repeatedly utilizes water resources, has complex hydraulic connections, and the power transmission areas of each power station overlap or share limited transmission channels, with close power connections. In addition, each power station has different relative positions in the basin, different affiliations, different dispatching entities, different regulation capabilities, and different installed capacity, which makes it show different characteristics, and thus has different support for the power of the entire network. The power dispatch of a large-scale hydropower-rich power grid needs to comprehensively consider the characteristics of each power station and the intricate hydraulic and power connections and time-lag relationships between power station groups. It is a nonlinear multi-constrained optimization problem with very high computational complexity, which makes it easy to cause dimensionality disasters in the solution process.

[0003] Existing methods have proposed the concept of "virtual reservoir" to divide hydropower clusters, but the "virtual reservoir" is only applicable to cascade power stations located in the same river basin, and is not applicable to large-scale hydropower-enriched power grids with hybrid series-parallel development. Moreover, it only considers the hydraulic connection between cascade power stations in the river basin developed in series, and lacks consideration of the power connection between hydropower stations and their contribution to the total power grid. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a method for dividing hydropower clusters that is suitable for power dispatching in hydropower-enriched power grids. The method is not only applicable to clusters of series-connected cascade hydropower stations, but also to clusters of cross-basin cascade hydropower stations developed in parallel. The method comprehensively considers the power section attributes, dispatching subject attributes, investment subject attributes, regulatory attributes, hydraulic connection attributes and installed capacity scale attributes of the power station, and is more suitable for power dispatching in hydropower-enriched power grids.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0006] A method for dividing hydropower clusters suitable for power dispatching of a hydropower-rich power grid comprises the following steps:

[0007] S1. Classify the hydropower stations according to their installed capacity data to obtain hydropower station scale data;

[0008] S2. According to the reservoir capacity regulation coefficient data of the hydropower station, the regulation capacity of the hydropower station is divided to obtain the regulation capacity data of the hydropower station;

[0009] S3. According to the power section data, dispatching subject data and investment subject data of the hydropower station, the hydropower station is divided into three-level clusters to obtain the third-level cluster data of the hydropower station;

[0010] S4. Obtain a hydraulic topology diagram with installed capacity attributes and regulation capacity attributes based on the relative position of the hydropower station in the watershed and the data of the upstream and downstream hydropower stations, the scale data of the hydropower station, the regulation capacity data of the hydropower station, and the third-level cluster data of the hydropower station;

[0011] S5. According to the hydraulic topology diagram with installed capacity attributes and regulation capacity attributes, combined with hydraulic connection attributes, the final hydropower cluster division result is obtained, and the power generation output of the hydropower cluster is calculated according to the final hydropower cluster division result.

[0012] Furthermore, in step S1, the hydropower station is scaled according to the installed capacity scale data of the hydropower station to obtain the scale data of the hydropower station. The specific process is: according to the installed capacity scale data of the hydropower station, it is determined whether the installed capacity of the hydropower station is greater than or equal to 50,000 kW; if so, the hydropower station is classified as a first-level hydropower station, otherwise, the hydropower station is classified as a second-level hydropower station to obtain the scale data of the hydropower station.

[0013] Furthermore, in step S2, the regulating capacity of the hydropower station is divided according to the reservoir regulation coefficient data of the hydropower station to obtain the regulating capacity data of the hydropower station. The specific process is: according to the reservoir regulation coefficient data of the hydropower station, it is judged whether the reservoir regulation coefficient of the hydropower station is greater than 2%; if so, the hydropower station is divided into a regulating hydropower station, otherwise, the hydropower station is divided into a non-regulating hydropower station to obtain the regulating capacity data of the hydropower station.

[0014] Further, step S3 includes the following steps:

[0015] S31. According to the power section data of the hydropower station, the hydropower stations belonging to the same power section are divided into the same sub-cluster, so as to perform first-level cluster division on the hydropower stations and obtain first-level cluster data of the hydropower stations;

[0016] S32. According to the dispatching subject data of the hydropower station, for each sub-cluster in the first-level cluster data of the hydropower station, the hydropower stations belonging to the same dispatching subject are divided into the same sub-cluster, so as to perform second-level cluster division on the hydropower station and obtain the second-level cluster data of the hydropower station;

[0017] S33. According to the investment subject data of the hydropower station, for each sub-cluster in the second-level cluster data of the hydropower station, the hydropower stations belonging to the same investment subject are divided into the same sub-cluster, so as to perform third-level cluster division on the hydropower station and obtain the third-level cluster data of the hydropower station.

[0018] Further, step S4 includes the following steps:

[0019] S41, for each sub-cluster in the third-level cluster data of the hydropower station, a hydraulic topology diagram is established according to the relative position of the watershed of the hydropower station and the data of the upstream and downstream hydropower stations;

[0020] S42, marking the installed capacity scale attribute on the hydraulic topology diagram according to the hydropower station scale data, and obtaining the hydraulic topology diagram with the installed capacity scale attribute;

[0021] S43. According to the hydropower station regulation capacity data, the regulation capacity attribute is marked on the hydraulic topology structure diagram with the installed capacity scale attribute, and the hydraulic topology structure diagram with the installed capacity scale attribute and the regulation capacity attribute is obtained.

[0022] Further, step S5 includes the following steps:

[0023] S51. According to the hydraulic topology diagram with installed capacity attributes and regulation capacity attributes, the regulating hydropower station is divided into a sub-cluster separately, and the non-regulating hydropower station is aggregated into a sub-cluster, so as to perform fourth-level cluster division on the hydropower station and obtain fourth-level cluster data of the hydropower station;

[0024] S52, aggregating the second-level hydropower stations of each sub-cluster in the fourth-level cluster data of the hydropower stations to divide the hydropower stations into fifth-level clusters, and obtaining fifth-level cluster data of the hydropower stations;

[0025] S53, obtaining a final hydropower cluster division result according to the fifth-level cluster data of the hydropower station and combining the hydraulic connection attributes;

[0026] S54. Calculate the power generation output of the hydropower cluster according to the final hydropower cluster division result.

[0027] Furthermore, in step S53, based on the fifth-level cluster data of the hydropower stations and in combination with the hydraulic connection attributes, the final hydropower cluster division result is obtained. The specific process is: for each sub-cluster in the fifth-level cluster data of the hydropower stations, determine whether there is a direct hydraulic connection between the hydropower stations; if so, the hydropower station is divided into a sub-cluster, otherwise the intermediate power station is determined as a boundary power station, and the upstream power station and the downstream power station of the boundary power station are respectively divided into a sub-cluster to obtain the final hydropower cluster division result.

[0028] Further, in step S54, the power generation output of the hydropower cluster is calculated according to the final hydropower cluster division result. The specific process is: determine whether the hydropower cluster in the final hydropower cluster division result has a regulating hydropower station; if so, use the regulating cluster calculation method to calculate the power generation output of the hydropower cluster; otherwise, use the non-regulating cluster calculation method to calculate the power generation output of the hydropower cluster.

[0029] Furthermore, the power generation output of the hydropower cluster is calculated by using a regulatory cluster computing method, including the following steps:

[0031] in: is the power generation output of regulating cluster r at time t, r is the identifier of the regulating cluster, t is the time, N t is the power generation output of the regulating hydropower station in the regulating cluster r at time t, i is the hydropower station number in the regulating cluster r, I is the total number of hydropower stations in the regulating cluster r, α i is the power generation output ratio of the i-th hydropower station in the regulating cluster r to the regulating hydropower station.

[0032] Furthermore, the non-regulatory cluster computing method is used to calculate the power generation output of the hydropower cluster, which is expressed as:

[0033]

[0034] Where: N t (n) is the power generation output of non-regulatory cluster n at time t, n is the identifier of the regulating cluster, t is time, Q t is the power generation flow of non-regulatory cluster n at time t, k is the conversion factor, δ n is the comprehensive water consumption rate of the non-regulatory cluster n.

This process comprehensively considers the power section attributes, dispatching subject attributes, investment subject attributes, regulation attributes, hydraulic connection attributes and installed capacity attributes of the power station. It is not only applicable to the cluster of series-type cascade hydropower stations, but also to the cluster of cross-basin cascade hydropower stations developed in parallel, and is more suitable for the power dispatch of hydropower-enriched power grids.

[0037] (2) The present invention calculates the power generation output of the hydropower cluster according to the final hydropower cluster division result, specifically by judging whether the hydropower cluster in the final hydropower cluster division result has a regulating hydropower station; if so, a regulating cluster calculation method is used to calculate the power generation output of the hydropower cluster; otherwise, a non-regulating cluster calculation method is used to calculate the power generation output of the hydropower cluster, thereby calculating the power generation output of the hydropower cluster.
