Problems solved by technology
The CCEM method is relatively easy to implement in radial power grids, but for complex power grids, it is difficult to rationally divide the partition boundaries due to the small difference in the power prices of nodes at the partition boundaries

Embodiment 1
[0174] The IEEE-39 node system is used to illustrate the dynamic partition pricing process. The network topology of the system is shown in the figure. The parameters of the line, transmission limit, and upper output limit of the generator set adopt typical parameters, and the lower output limit of the generator set is 40% of the upper limit of each generator set. 50%.
[0175] In this paper, four typical instances are selected as the object of analysis and calculation, among which instance 1 is used as the initial instance. In order to reflect the change of load distribution mode, the load distribution ratio of Example 2 is the same as that of Example 1, and the load level has changed; the load level of Example 3 is the same as that of Example 1, but the load distribution ratio has been slightly modified; the load level of Example 4 and The load distribution ratio is changed on the basis of Example 1. The specific data are shown in Table and Table 4. Due to the lack of quota...

The invention provides a construction method of an analytic model of dynamic partitions, which comprises the following steps: determining a blocked line set, an optimal partition number and attribution of power generation nodes to partitions based on quotation information, blocked line information, power grid power flow distribution and a topological structure of each power generation node of a power grid; obtaining the attribution of the non-power-generation node to the partition based on the information by using a fusion algorithm; and determining the optimal affiliation of all the nodes tothe partitions, and dividing clear boundaries among the partitions. Through an analytic dynamic partition model taking node electricity price drop as guide and fusion algorithm taking blocked line analysis as guide for node partition affiliation, a complete comprehensive dynamic partition pricing model based on an analytic method and a fusion algorithm is established. The analytic method successfully solves the problem of unit partition and the problem of regional intersection of power generation nodes which are not solved in the past, the fusion algorithm solves the problem of partition boundaries, and the method has a good application prospect.
Description
technical field [0001] The invention belongs to the field of power system operation, and particularly relates to a method for constructing an analytical model of dynamic partitions. Background technique [0002] The electricity price mechanism is the core issue of the electricity market. In the long-term development of electricity markets in various countries in the world, there are mainly three pricing mechanisms: system marginal pricing, zonal marginal pricing and nodal pricing mechanism. With the deepening of transmission pricing and congestion management research, more and more researches have begun to focus on the use of regional electricity pricing mechanisms to simplify transmission pricing and congestion management based on the two electricity price mechanisms of the whole network unified price settlement and node marginal price settlement. [0003] A large number of practices have shown that congestion occurs frequently in lines between certain areas, while intra-a...
