Abstract: This paper presented a method of multi-voltage level coordinated expansion planning in distribution network.Considering the effect of transmission system and the main electric connection schemes of substation,the reliability parameter of transmission is equivalent to the distribution network power node for multi-voltage level reliability calculation.Based on life cycle cost(LCC),the assessment of reliability and economy is carried out,which selects the unit cost of average service availability index(ASAI) increment as the objection function.Finally,the proposed method was well applied to different improved planning,and the optimum conditions are obtained which serves the long-term interests of power grid.

Key words: multi-voltage level, reliability and economy analysis, unit cost of ASAI increment, life cycle cost
