Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] The following is a preferred implementation case of the present invention, including a power trading flow optimization process using the method of the present invention, including the following steps:

[0044] (1) Construct an aggregated network model based on the physical model of the power grid.

[0045] Such as figure 1 As shown, through model aggregation, all generating units in the same province are aggregated into a provincial power generation node, and inter-regional and inter-provincial contact lines are aggregated into transmission sections. In this case, the models are Shaanxi, Gansu, and Qinghai in the Northwest Power Grid , Ningxia, and Xinjiang provinces, as well as Hubei, Hunan, Henan, Jiangxi, Sichuan, and Chongqing of Central China Power Grid. Such as figure 1 shown.

[0046] (2) Set the power ...

Abstract

The invention relates to a power transmission stream optimization method involving power transmission paths. The method includes the following steps that (1), a network model is constructed; (2), an electric energy exchange transmitter and an electric energy exchange receiver are set; (3), the physical power transmission paths are all traversed; (4), optimization parameters are set; (5), a power transaction stream optimization model is established; (6), optimization calculation is performed. On the basis of traversing all the power transmission paths, combined optimization is performed; through a linear programming method, transaction stream optimization is achieved, a complex non-linear path optimization problem is transformed into the linear problem, and therefore the practical level of power transaction stream optimization is easily increased.

Description

technical field [0001] The invention relates to an optimization method in the field of electric power automation, in particular to a power transaction flow optimization method involving power transmission paths. Background technique [0002] The reverse distribution of energy resource centers and load centers determines that power resources must be allocated on a larger scale. In particular, the rapid development of clean energy such as wind power and photovoltaics cannot be fully accepted by the region due to the limitations of the regional economic level and power consumption level. It has become a major factor to promote the development and utilization of clean energy through large power grids and large markets. inevitable choice. [0003] The rapid construction of UHV-based trans-regional and inter-provincial power grids provides a material basis for inter-regional and inter-provincial power exchange. When the supplier of a certain power exchange with multiple power re...
