Problems solved by technology

The current research has not considered the use of segmented switches to divide islands in the planning stage, reduce the loss of power outages in the distribution network, and promote the active consumption of DG in the distribution network through economic signals, and both DG and reactive power compensation devices are regarded as distribution networks. The power grid company owns and conducts unified planning, without considering that DG, reactive power compensation device and switch are subordinate to two different entities, the DG generator and the distribution network company respectively

Embodiment Construction

[0059] Such as Figure 5 As shown, the embodiment selects the IEEE33 node system as an example, and deploys two DGs in the IEEE33 node system, and applies the method of the present invention to the installation position, capacity, reactive power compensation device, and section switch of the two distributed power sources. The layout is optimized.

[0060] Such as Figure 1-4 As shown, the distributed power two-tier planning method includes the following steps,

[0061] Step 1: Analyze each node of the power distribution system through the network loss sensitivity method, and obtain the sensitivity of the network loss to the active and reactive power of each node;

[0062] DG can meet the load demand of the distribution network nearby and reduce the power transmission distance, so reducing the system network loss is one of its main values, and it is also an important evaluation index for site selection planning; similarly, reducing the system network loss is also the purpose ...

Abstract

The invention discloses a distributed power supply double-layer planning method. The method comprises: calculating the sensitivity of network loss to each node; selecting a node with high loss sensitivity as a candidate installation position of the distributed power supply and the reactive power compensation device; determining candidate installation positions of the section switches by adopting an island region division method; establishing an upper-layer model and a lower-layer model of the distributed power supply double-layer planning model; and solving the double-layer planning model of the distributed power supply to obtain the installation position and capacity of the distributed power supply, the installation position and capacity of the reactive power compensation device and the installation position of the section switch. According to the invention, the upper layer model optimizes the installation position and capacity of the distributed power supply, and the lower layer model optimizes the installation position and capacity of the reactive power compensation device and the installation position of the section switch, thereby achieving the optimization and coordination ofthe planning and operation of the distributed power supply. An island area division method is introduced, the installation position of the section switch is optimized, and the power failure loss is reduced to the maximum extent by utilizing a distributed power supply.

Description

technical field [0001] The invention belongs to the field of distributed power supply planning, and in particular relates to a two-layer planning method for distributed power supply. Background technique [0002] As the penetration rate of distributed generation (DG) in the distribution network continues to increase, DG has had a profound impact on many aspects of the distribution network. On the one hand, DG can improve the network loss of the distribution network system, reduce the power outage loss, and delay the system upgrade and transformation time; on the other hand, due to the transformation of the traditional passive distribution network Due to the operating characteristics of the power grid, in order to ensure the safety and stability of the system, the distribution network company has to increase planning investment. However, due to the lack of coordinated planning between the two parties, the planning of both parties is unreasonable, making it difficult for the d...
