Abstract: The life cycle cost of power grid assets is a key technology in power system planning to control long-term cost and short term investment. Considering the effects of reliability, economic indicators and different replacement cycleson the cost calculation, this paper proposes a cost calculation model base on LCC for transmission network to compare and select the schemes of smart grid planning. Meanwhile, in combined with the theory of power network reliability analysis and LCC theory, this paper proposes the reliability index calculation and quantitative method based on Monte Carlo model, studies the effect of different load types on reliability cost, and then establishes the LCC cost model of power grid planning with considering the replacement of equipment. Finally, this paper verifies the accuracy and effectiveness of the proposed LCC cost calculation model through an appropriately example of comparing and selecting of two planning schemes for an 110 kV substation.

Key words: life cycle cost (LCC), Monte Carlo model, reliability calculation, power grid planning
