Problems solved by technology

In the environment where the original distribution network and the incremental distribution network coexist, the failure to uniformly plan and deploy the distribution network will lead to improper unit output. If the unit output is improper, it will inevitably lead to waste of resources and even affect the operation quality and safety of the power system.
[0003] In the traditional situation, the method of unified planning of the distribution network by the power grid company is no longer suitable for the distribution network planning problem under the new electricity reform situation.

Embodiment Construction

[0032] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 Shown is the flow chart of the distribution network planning method based on different distribution network investment entities under the liberalization of incremental power distribution business. The following will describe each step in detail.

[0034] Step 1: Distribution network optimization is performed separately for distribution network 1, distribution network 2 and distribution network 3, and the optimization goal is to meet the specified reliability requirements and minimize the planning cost under constraints.

[0035] by the grid company W 1 The objective function f of the power distribution network to be built 1 for:

[0036]

[0037] In formula (1), k 1 For the grid company W 1 The line capital recovery coefficient of the invested and built distribution network; v 1 For the grid company W 1 Proportion o...

Abstract

The invention discloses a distribution network planning method based on different investment entities under the liberalization of incremental power distribution services, and belongs to the technical field of distribution network planning. Establish the optimization model of the power distribution network invested and built by the power grid company and the incremental power distribution network invested and built by other different investment entities. The economic and technical effect that the power grid and the incremental distribution network are mutually backup makes the investment cost of the power distribution network built by different investment entities to meet their respective reliability requirements the smallest, which can provide theoretical support and solutions for subsequent actual power grid planning.

Description

technical field [0001] The invention discloses a distribution network planning method based on different investment entities under the liberalization of incremental power distribution services, and belongs to the technical field of distribution network planning. Background technique [0002] With the introduction of the new document No. 9, the release of incremental power distribution business has become the focus of attention. The connection of the distribution network with the transmission network and users is a key link to ensure the safety and stable supply of electricity, and its planning and construction are physically a natural monopoly link. The liberalization of the power distribution business means that the distribution network has changed from the previous situation that the power grid company planned and constructed it in a unified way. Private capital and social groups can invest in the construction of the power distribution network, which brings great benefits ...
