Evaluation of 10 kV Distribution Network Investment Allocation Based on Multi-Index System
With the increase of the investment on distribution network,a system of evaluation indexes and methods for grid investment allocation is necessary.In this paper,the investment allocation evaluation index system for 10 kv distribution network is established in view of six aspects,i.e.security,reliability,economy,flexibility,coordination and environmental impact.Fuzzy mathematical comprehensive evaluation method is used,and the weighting method based on blind number theory is adopted for index weight considering the influence of objective data and investment planners' attention to each data.Finally,the investment allocations of 10 kV network in a Southeastern power company in 2010 and 2011 were evaluated and the evaluation results show that its investment allocation was reasonable.
