Problems solved by technology

The adaptation process of the traditional virtual power plant business and different communication methods is simply based on indicators such as bandwidth, delay, and transmission rate. It is difficult to accurately express the differentiated business requirements of the virtual power plant business. A comprehensive approach to building business needs
[0005] 2) Relying on a single communication method, the communication channel of the virtual power plant is independent
In the traditional virtual power plant communication index system, the adaptation process of virtual power plant business and communication mode is simply to select technology based on transmission distance, network security and construction cost, etc., and the adaptation index is not comprehensive enough to accurately express the multi-service of virtual power plant Differentiated application requirements

Embodiment 1

[0097] The virtual power plant business demand index system construction and communication mode adaptation method of the present invention, the specific steps are as follows figure 1 shown:

[0098] (1) Extraction of business demand indicators for virtual power plants

[0099] Aiming at the extraction of multi-data communication business indicators in virtual power plants, such as reliability, effectiveness, economy, adaptability, safety and other indicators, the feature extraction of differentiated business requirements and application scenarios of virtual power plants is carried out to form first-level indicators. Specifically, it includes basic communication capability indicators and practical application feasibility indicators. Among them, the basic communication capability index is mainly used to evaluate the service quality of the access mode, and the practical application feasibility index is mainly used to measure the economy, security, and adaptability of the selecte...

Embodiment 2

[0138] The present invention also provides a virtual power plant business demand index construction and communication mode adaptation system, including:

[0139] The index obtaining module is used to obtain the business demand index of the virtual power plant; the business demand index of the virtual power plant includes two first-level indexes, which are the basic communication capability index and the practical application feasibility index respectively.

[0140] Analysis module: used to analyze the business demand indicators of the virtual power plant layer by layer to obtain the indicator system; the details are as follows:

[0141] The basic communication capability index is divided into two second-level indexes, which are the effectiveness index and the reliability index respectively; the effectiveness index includes three third-level indexes, which are the transmission distance, the transmission bandwidth, and the number of access terminals. Reliability indicators inclu...

Embodiment 3

[0165] Below in conjunction with specific embodiment, the present invention is described in detail:

[0166] In the present invention, the weight of the business demand index of the virtual power plant is first determined. Taking the effectiveness index as an example, the judgment matrix is ​​constructed and assigned for different levels of indicators. Assume that the important scale of the transmission bandwidth of a virtual power plant to the transmission distance is 5, and the important scale of the transmission bandwidth compared with the number of access terminals is 3. The importance scale of the number of access terminals compared to the transmission distance is 4. Then the judgment matrix is ​​obtained as shown in Table 4.
