Problems solved by technology

However, the traditional node electricity price does not take into account the change of network transmission margin after wind power is integrated, does not have strong risk management capabilities, and is not conducive to dispatchers to analyze line transmission margins, and it is difficult to fully reflect the value of wind power grid integration

Embodiment Construction

[0062] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0063] The invention provides a wind farm value evaluation method based on node electricity price, comprising the following steps:

[0064] Step S1, extracting system information, operating parameters and network parameters:

[0065] Step S2: The optimal power flow objective function is based on the lowest operating cost of the system and the optimal power flow of the power system without wind power. The primal-dual interior point method is used to obtain the electricity price of each node, the number of the heavy-duty line and the transmission capacity of the heavy-duty transmission line, and calculate Transmission margin r of each line without wind power l ,Right now

[0066]

[0067] Among them, h l is the power flow on line l; F l max is the maximum transmission capacity on the line l; r l is the transmission margin of the he...

Abstract

The invention relates to a node electricity price calculation method considering the wind power grid-connected transmission margin value. It is proposed to consider the line flow transmission margin value of wind power grid-connected, and integrate it into the node power price, so that the node power price including wind power includes four components: energy consumption, network loss, congestion and line transmission margin, which is different from the conventional node power price , which usually only includes the first three parts, the electricity price of this node can fully reflect the value of wind power, and at the same time improve the system risk management capability.

Description

technical field [0001] The invention relates to the field of optimal operation of electric power systems, in particular to a calculation method for node electricity price considering the value of wind power grid-connected transmission margin. Background technique [0002] The node electricity price refers to the change of the marginal cost of power supply caused by a slight increase in the load of a node, and usually includes three parts: energy, congestion and network loss. The node electricity price can reflect the value of electric energy at different moments in different geographical locations of the system, reflect the scarcity of electric resources, improve the efficiency of the use of electric resources, and optimize the allocation of electric resources. With the grid connection of large-scale wind power, due to its characteristics of energy saving, low marginal operating cost, the node electricity price generally drops. However, the traditional node electricity pric...
