摘要
针对不同资源禀赋下分布式智能电网建设策略难以精准投资的问题,提出了一种融合群体智慧的分布式智能电网高效发展管理策略。首先,依托海量分布式智能电网发展规划数据,利用Ward凝层聚类,从运行、规划及发展3个方面构建分布式智能电网发展最优指标集;其次,结合指标类型拟合其概率分布函数,确定各指标阈值区间,实现指标的客观打分;然后,构建基于群体智慧的分布式智能电网发展精准投资评估体系,利用指标横纵差异度驱动群体智慧重新赋权,实现分布式智能电网建设策略的合理评估;最后,通过计算发展规划投入产出比形成闭环反馈,实现分布式智能电网高效发展管理。通过对某省10 000组发展规划数据的分析评估,验证了所建体系的合理性。
To overcome the challenge of accurately investing in the construction strategies of distributed smart grids under different resource endowments,an efficient development and management strategy for distributed smart grids based on collective intelligence was proposed.Firstly,relying on development planning data of massive distributed smart grids,the optimal index set for the development of distributed smart grids was constructed from three aspects of operation,planning,and development by using Ward agglomerative hierarchical clustering.Secondly,the corresponding probability distribution function was fitted according to the type of each index,and the index threshold interval was determined to achieve the objective scoring of each index.Then,the precise investment evaluation system for the development of distributed smart grids based on collective intelligence was constructed,and the horizontal and vertical difference degree of indexes was used to drive the re-weighting of collective intelligence,so as to achieve the rational evaluation of distributed smart grid construction strategy.Finally,the closed-loop feedback was formed by calculating the input-to-output ratio of the development planning,and efficient development and management of distributed smart grids was achieved.
