Embodiment Construction

[0053] In order to better understand the purpose, technical solutions and technical effects of the present invention, the present invention will be further explained below in conjunction with the accompanying drawings.

[0054] The present invention proposes a distribution network substation-line joint planning method based on parallel computing, and its implementation process includes the following detailed steps:

[0055] Step 1. Obtain substation information, load information and line information in the area to be planned.

[0056] Step 2. Considering the impact of the opposite side substation that does not supply power to the load point but is connected to the load point during normal operation, a joint planning model of the substation-grid that is suitable for the urban cable ring network is proposed:

[0057] The grid frame of the distribution network includes trunk connection, double T connection, ring connection and so on. Q / GDW 10370—2016 recommends that ring network...

Abstract

The invention relates to a parallel calculation-based power distribution network substation-circuit combined planning method. The parallel calculation-based power distribution network substation-circuit combined planning method comprises the steps of considering influence of an opposite-side substation which is not used for supplying power to a load point and is connected with the load point during normal running, and proposing a substation-net rack combined planning model applicable to an urban cable looped network; transforming the model to a dual-layer structure for iterative solution on substation locating and sizing and net rack planning; performing parallel transformation of a master-slave structure on a flock algorithm to form an improved parallel flock algorithm; employing the improved parallel flock algorithm to calculate the model with regard to a large amount of repeated calculation process of a planning target function, capacity verification, N-1 verification and the like.With the adoption of the method, a more reasonable planning result can be solved; and meanwhile, with the improved flock algorithm proposed by the invention, the running time of a program can be effectively reduced when the process number is reasonably configured, and the calculation speed of the planning process is improved.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method for joint planning of distribution network substations and lines based on parallel computing. Background technique [0002] In the process of distribution network planning, after sorting out the status quo of the distribution network in the planning area and obtaining the load forecast results, it is necessary to balance the power and electricity, clarify the construction requirements of substations of each voltage level, and then proceed to the site selection, capacity adjustment and maintenance of new substations. Expand the constant capacity of the substation, and then plan the overhead lines or cable grids of the distribution network, or plan the substations and grids uniformly after the power and electricity balance. However, traditional planning models usually only consider the selection of substations that supply power to load points, so it is necessary to improve the...
