Embodiment Construction

[0040] Such as figure 1 As shown, a power transmission method that optimizes the arrangement of the energy base’s external transmission channels, establishes an optimization model for the energy-saving and low-carbon development of the transmission point mode, and the decision variable of the model is increased from a single unit to a type of unit; the receiving end system is simplified to a single node , ignoring the grid structure and loss of the receiving end power grid, the power transmission channel in the outer area, various types of units and loads at the receiving end are all connected to the same node; on the basis of the operation plan of the generating units, the output of various units at each time is taken as the decision variable; a certain economic cost is assigned to each unit of carbon emission, and it is combined with the total operating cost of the system as an optimization goal.

[0041] Based on the planning parameters of the Ximeng-Shandong UHV power tran...

Abstract

The invention discloses a power transmission method for optimization arrangement of transmission channels of an energy base. A transmission point optimization model for energy saving and low carbon development is established. The method is characterized in that a decision variable of the model is promoted from a single unit to a type of unit; a receiving end system is simplified as a single node, the rack and loss of a receiving end power grid are ignored, and outer region transmission channels, various types of units at the receiving end and loads are connected to the same node; on the basis of a commissioning plan of generator units, the output of each type of unit at each time is taken as a decision variable; and the carbon emission per unit is given a certain economic cost, which is combined together with the total operating cost of the system as an optimization goal.

Description

technical field [0001] The invention relates to the field of grid planning and operation, in particular to a power transmission method for optimally arranging energy base transmission channels. Background technique [0002] The core concept of carbon emission flow is that the cost of carbon emissions generated in the process of electric energy production should be borne by the electricity consumption link, and the measurement of carbon emissions corresponding to electricity consumption can be realized from the user side, so as to clarify the low-carbon emissions of each region under the condition of power exchange. Development responsibility and contribution. Carbon flow analysis puts a "carbon label" on the transmission of inter-regional electric energy, redefines the distribution of carbon emission costs, helps mobilize consumers' low-carbon enthusiasm, and fundamentally promotes the development of low-carbon electricity. The relevant analysis concept has received widespr...
