Embodiment 1

[0067] For ease of understanding, see figure 1 , Embodiment 1 of an optimized power transmission right allocation method provided by the present application, including:

[0068] Step 101. According to the preset time distribution coefficient, the preset unit distribution coefficient and the total annual power generation of the system, the total electricity value of the transmission right assigned by the computer group is calculated.

[0069] It should be noted that the preset time distribution coefficient generally refers to the correlation coefficient of the power generation time of the system throughout the year; the preset unit distribution coefficient generally refers to the correlation coefficient of normal generating units in the system; these coefficients can be determined according to the actual situation of the power generation system setting, and is not limited here.

[0070] Step 102, combining the total power value of the power transmission right, the preset propo...

Embodiment 2

[0079] For ease of understanding, see figure 2 In the embodiment of this application, a second embodiment of an optimized power transmission right allocation method is provided, including:

[0080] Step 201, define the preset time distribution coefficient according to the ratio of the power generation in the preset distribution period to the total annual power generation of the system.

[0081] It should be noted that the total amount of distributed electricity is determined according to the annual power load of the system. The distributed electricity of each distribution period is equal to the sum of the power generation of all generating units in this period, and the preset time distribution coefficient is defined as the preset distribution period The ratio of the power generation of the system to the total annual power generation of the system, the specific first preset definition formula is:

[0082]

[0083] Among them, Q i,j is the power generation of unit i in the...

Abstract

This application discloses an optimized power transmission right distribution method and device, the method includes: according to the preset time distribution coefficient, the preset unit distribution coefficient and the total power value of the power transmission right assigned by the system's annual total power generation computer group; combined with the power transmission right The total power value, the preset proportional coefficient and the preset time are used to calculate the distribution of power transmission rights of the generator set; the total distribution income of transmission rights is calculated according to the distribution of power transmission rights; it is calculated through the preset node electricity price, node power generation and node power consumption The total congestion surplus; when the total congestion surplus is less than the total distribution revenue, adjust the distribution of transmission rights to obtain the optimized distribution of transmission rights. The present application solves the technical problem that the existing technology does not consider the impact of the congestion surplus on the distribution of power transmission rights, which leads to the unstable development of the power supply market.

Description

technical field [0001] This application relates to the technical field of electric power market, in particular to an optimized method and device for allocating power transmission rights. Background technique [0002] Compared with general commodities, spot power has characteristics such as "electric energy cannot be stored in large quantities" and "transmission is limited by the capacity of transmission lines". In the current electricity price mechanism for spot nodes in the electricity market, when the transaction plan is subject to the physical constraints of the power network, the following phenomena will directly occur in the spot electricity price: The output of the node unit that is blocked from the power transmission is cut, and the node electricity price is reduced; in order to meet the power demand of the system, The high-cost units are dispatched to work, and the node electricity price rises; eventually, there is a price difference between the nodes of the whole sy...
