The invention provides a method for optimizing a power grid planning scheme based on a comprehensive cost model. According to the method, the comprehensive cost model, which adopts the planning target age limit as a boundary and considers the annual cost and the current value of a planned scheme at the end of the year, is created. The calculating range of the model is the grid equipment (substations and transmission lines) which produces variable amount of costs in the scheme, wherein economic life of old equipment is needed to be forecasted to determine whether needing to update and when updating within the planning period. Meanwhile, fault rate forecast of new and old equipment within the planning period is trained and output through a least square support vector machine algorithm. In addition, when the comprehensive cost model is applied to comparing planning schemes, in order to reduce the influence on error of economic variables, an interval method is adopted. Numerical examples show that economic optimization of the power grid planning scheme is effectively realized by combining the comprehensive cost model with the interval method, and the comprehensive cost model is suitable for planning target age limits in various lengths.
