源-网-荷-储一体化环境下复杂电网投资决策指标体系的研究

Research on the complex grid investment decision indexes system under the integrated source-grid-load-storage environment

从源—网—荷—储的单一环节和多元交互出发,构建了复杂电网投资决策指标体系。为计及复杂电网中各侧指标的依存和反馈关系,考虑决策者的指标偏好及指标包含的信息量,将ANP-EWM组合赋权法引入到投资决策中。首先,提出复杂电网中源、网、荷、储的单侧指标和考虑网源交互、荷网交互、源荷交互、源储交互、荷储交互、网储交互的交互指标,建立投资决策指标体系;其次,利用博弈论得到ANP-EWM组合赋权法为指标赋权;最后,使用优劣解距离法求取项目总效用值。以IEEE 39节点系统为例,将所提方法与其他赋权法进行比较,验证所提方法的有效性。

A complex grid investment decision indexes system is established from the single component and multiple interactions of source⁃grid⁃load⁃storage.To take the interdependence and feedback relationships of the indexes on each side of the complex grid into account,the ANP⁃EWM combined weighting method is introduced into the investment decision,considering the preferences of decision makers and the information contained in the indicators.Firstly,the unilateral indices of source,grid,load and storage in complex grids and the interaction indices considering grid⁃source interaction,load⁃grid interaction,source⁃load interaction,source⁃storage interaction,load⁃storage interaction and grid⁃storage interaction are proposed to establish the investment decision index system.Then,the ANP⁃EWM combined weighting method is designed using game theory to assign weights to the indices.Finally,the overall utility value of the project is calculated using the distance vector merging algorithm.Taking the IEEE 39⁃node system as an example,the proposed method is compared with other weighting methods to verify its effectiveness.
